Homemade Acne Treatment which Works

Home made treatments are appreciated for acne since most of the applications are external. Deep in your skin, water is a crucial component, providing the basis of a healthy, soft and youthful complexion. Without an adequate supply of water, your cells cannot rebuild your body, nor can they clear waste products which stack up in the cells and your blood. One of the most effective homemade acne treatment methods is to wash the face with soap and water at least twice each day. Preferably, first thing in the morning and once again before going to bed at night. Vitamin B5 deficiency is believed to be the root of acne, and supplementation with vitamin B5 can help to alleviate acne. Vitamin B5 plays a vital role in the production of Coenzyme A, as it metabolizes the skin oil. Deficiency in these vitamins leads to the growth of bacteria that clogs the skin oil which leads to acne. There are so many treatments are available for the acne. The acne treatment contains home remedies, some medications, creams and many more. The acne can be controlled by using the proper treatment. Homemade treatments start with careful cleaning of the skin. Rosewater is usually suggested in most of the treatments. Low concentrated alcohol is also suggested in a few treatments for cleaning. Milk and curd are recommended for the cleaning of those affected by dry skin. Cleaning is important in acne treatment because it removes the dirt in the skin and opens up the pores. Oatmeal is used for both cleaning the face and as a face pack for the treatment.What are homemade acne treatments?Rub lemon on your skin before going to sleep and you will find a clear skin in the morning. Blending the clay with some water to form a paste and applying it to skin can draw out toxins and dirt. Grated cucumber applied over the face, eyes, and neck for fifteen to twenty minutes has been found effective. To wash the face with soap and water at least twice each day. The aloe vera, calendula and chamomile may be applied to face for acne. Raw papaya can also help reduce the swelling and soreness of acne. Whisk together 1 tablespoon honey, 1 egg white, 1 teaspoon glycerin (available at drug and beauty stores) and enough flour to form a paste. Smooth over face and throat. Leave on 10 minutes. Wash off with warm water. The acne facials are used for to reduce the acne. To avoid of fatty and oily foods. Tomatoes are also a great acne home remedy. Including large amount of fruits and vegetables in the diet and drinking lot of water are part of acne treatment. Zinc is another effective remedy in the area of nutrition that seems to offer new promise of help for acne.

Vitamins A, C, E and quasi-vitamins Coenzyme Q10 and alpha lipoic acid are powerful antioxidants that neutralize the damage caused by free radicals and oxidation. Our body’s cells are undergoing a continuous cycle of oxidation (losing an electron) and reduction (gaining an electron). Oxygen and other atoms or molecules that are unstable because they lack an electron are called free radicals. These free radicals don’t like to exist in an unstable state and will steal another electron from where ever they can and can damage the cell that they oxidize. Free radicals are created as part of the body’s normal metabolic process and if there are insufficient antioxidants available to donate electrons and neutralize the free radicals then cell damage will result. When we are young, the body generates some of the antioxidants it needs and it acquires the remainder from the food we eat. As we get older, the body generates fewer antioxidants and the free radicals outnumber the antioxidants. This means the body is unable to repair the free radical damage and it ages and becomes subject to age-related degenerative diseases like cancer, diabetes, heart disease, strokes, Alzheimer’s disease, and macular degeneration. Additional free radicals are created when we expose our body to the sun’s ultraviolet radiation, cigarette smoke, exhaust fumes and other air and water pollutants. Approximately 10 million people in North America have cancer and about 600,000 people will die from it this year. Until recently, we thought the key to slowing the aging process and associated diseases was to ensure the body had an excess supply of antioxidants by eating lots of fruits and vegetables and supplementing our healthy diet with multi-vitamins.

For years we assumed it was the vitamins in fruits and vegetables that provided us with a defense against aging and age-related diseases. We also wanted to ensure we had an adequate supply of vitamins so we took low dose once-a-day-type multivitamins for insurance. However long term studies have shown that low dose multivitamins had no impact on the survival of healthy people. Recently scientists have theorized that the health benefits due to eating fruits and vegetables may be from other nutrients such as phytochemicals or the combination of phytochemicals and vitamins. Phytochemicals or phytonutrients are simply “plant chemicals” that exist in fruits, vegetables and other plants like whole grain and tea. Scientists have already discovered thousands of phytochemicals and think that as well as being powerful antioxidants these phytonutrients provide our body with an entire range of health benefits. A few examples of foods, the phytochemicals they contain, and their health benefits are discussed below.

Blueberries, strawberries, raspberries, cranberries and other berries contain the phytonutrients anthocyanidin and ellagic acid which are antioxidants that can suppress cancer and protect against heart disease. Berries are also rich in soluble fiber which should lower our cholesterol. Citrus fruits such as oranges, lemons, limes etc. contain flavanones such as limonoids which help stimulate the body’s enzymes to detoxify carcinogens. These citrus fruits also contain carotenoids which are powerful cancer fighting antioxidants and flavonoids which are antioxidants that may inhibit blood clotting.

Cruciferous vegetables like broccoli, brussel sprouts, kale, cabbage, cauliflower etc. contain indoles which act to make estrogen less potent and which may reduce the risk of breast cancer. These vegetables also contain isothiocynates such as sulphoraphane which may neutralize cancer-causing chemicals and interfere with tumor growth. Orange and yellow fruits and vegetables like apricots, papaya, sweet potatoes, carrots, sweet peppers, etc. and leafy greens such as spinach contain carotenoids such as beta carotene, lutein and zeaxanthin that are powerful antioxidants that should suppress cancer, strengthen the immune system and reduce the risk of atherosclerosis. These colorful foods are also rich in Vitamin C, other vitamins, minerals and fiber and should reduce the risk of macular degeneration.

Non-traditional healthy foods such as tea, wine and soy have also been found to be high in phytonutrients. Both green tea and black tea contain flavonols which combat cancers and catechins which may protect arteries from the buildup of plaque. Red wine contains resveratrol which may prevent internal cell and skin cell damage, inhibit tumor growth and lower blood cholesterol. Other phytochemicals in red wine are flavonols like quercetin and catechins, anthocyanidins and ellagic acid which were discussed earlier. Soy products contain isoflavonoids, lignans, saponins and protease inhibitors which can all provide cancer protection.

Products to combat aging and degenerative diseases are being developed. Both Pfizer and Merck are testing drugs to stimulate the older body to make more growth hormone and develop more lean muscle mass. Controlled studies on seniors are showing a lot of promise. Phytonutrient supplements like lycopene and beta carotene have been available for some time. The next supplements based on groups of phytonutrients that target specific conditions are already being marketed. How effective they will be remains to be seen. For now we should concentrate on obtaining our phytonutrients from our healthy diet and monitor developments in the pharmaceutical and nutritional supplement industries.

Healthy eating is difficult to achieve because we have so many health factors to consider and food choices to make. We know antioxidants are good for us so we want to eat lots of colorful fruits and vegetables because they contain phytochemicals like carotenoids and flavonoids which neutralize the free radicals that cause the age-related degenerative diseases. We know that we may not get all the antioxidants that we need in our food so we take supplements to ensure an adequate supply of antioxidants. But what about the actual food we eat. One of the major problems with our modern diet is that the food we eat is a tasty combination of saturated fats and highly processed and quickly digested carbohydrates. However in the last several years, people have become so concerned about fats in their diet that they have substituted carbohydrates and avoided even the good unsaturated fats in lean meat, olive oil and other plant oils. Now everybody seems to be eating a medium- to high-carbohydrate diet without giving proper attention to the type of carbs that they eat.

Not all carbohydrates behave the same in our bodies. We have been told for years to avoid simple carbs like honey and white bread and eat complex carbohydrates that our body doesn’t digest and turn to glucose as quickly. However determining whether a food containing carbohydrates is absorbed and raises our blood sugar quickly or slowly is not at all intuitive. Scientists have done a lot of rigorous testing over the past several years and have found that white bread and baked potatoes raise our blood sugar level much faster than honey, jams and chocolate bars. These scientists developed a numerical index called the Glycemic Index or GI to compare the ability of different carbohydrate containing foods to raise the body’s blood sugar levels – or in other words the speed of conversion to glucose. GI values are determined by feeding human subjects who have fasted overnight a fixed amount of the food and then measuring their blood glucose levels at fixed intervals of time. Pure glucose is set at 100 and then other foods are compared to this profile. Testing is time consuming and the tests have to be averaged for a number of individuals. However these studies have yielded some surprising results such as the fact that the starches in rice, bread, potatoes and many types of cereals were absorbed and raised blood sugars very quickly but the sugars in fruit, candy, chocolate and ice cream did not result in prolonged rises in blood sugars. In other words many of the starchy foods had a much higher Glycemic Index than many of the sugary foods. Needless to say these results seem counter intuitive and have caused a lot of controversy in the food industry. The rate of absorption is very dependant on how the carbs are bound up with the food fiber and the particle size. For example less gelatinized products like al dente spaghetti and oatmeal have lower GI values and stone ground flours have lower GI values than finely ground flours. The fibrous coat surrounding beans and seeds stop enzymes from getting at the starchy carbs inside and will slow the digestion of grainy breads, legumes and barley. The acidity of foods also slows down digestion and vinegar, lemon juice, pickles and sourdough bread will result in lower GI meal values.

The Glycemic Index is important not only to diabetics but also to non-diabetics because we need to know what foods will keep our blood sugars on an even keel and not raise them too high and then have them plummet down again causing hunger. The slow digestion of low GI foods and the gradual rise and fall in blood-glucose response helps people with diabetes control their blood sugar levels and increase their sensitivity to insulin. Low GI foods will help healthy people delay hunger pangs and promote weight loss in overweight individuals. In addition low GI carbohydrates can reduce blood cholesterol levels and also reduce our risk of heart disease. High blood glucose spikes can result in oxidative stress leading to the formation of plaque that can cause atherosclerosis and even blood clots. So keeping our blood sugar levels fairly level and low seems like what we should be trying to achieve through healthy eating. How do we go about achieving this?

The first step is to look at what carbohydrates we are consuming and the GI levels of the meals that we are eating. Then we should try and ensure we have at least one low GI food in each meal to keep the overall meal GI close to 50. Most fats and proteins have no effect on the GI level of our meal because they don’t contain carbs. However watch out for saturated fats and too many calories. Let’s look at some meals and see what substitutions we could make. The GI values are shown in brackets.

Breakfast

Cut back on Corn Flakes (92), Rice Krispies (82) and substitute All-Bran (32) or switch to a cereal based on oats, barley or bran. Stop eating white bagels (72), white bread (70) or whole-wheat bread (77) and switch to pumpernickel (50) or sourdough (55). Fruits are mostly low GI foods and surprisingly orange juice (46) is very good.

Lunch and Dinner

Eat your colored vegetables and make your salad dressings with olive oil and vinegar. Avoid parsnips (97) and substitute pastas like al dente white spaghetti (38), linguini (46) or macaroni (47) for Instant white rice (87) and potatoes – baked (85), red-skin peeled and boiled (88). Except for parsnips and potatoes most vegetables have a low GI value.

Additional information on GI values can be found at the University of Sydney website www.glycemicindex.com/ or in the “The New Glucose Revolution: Shopper’s Guide to GI Values 2006.

Child Obesity and Preventive Measures

It is extremely difficult to remove obesity from the body once it gets established. And therefore, it is advisable to take proper care of all those children who are becoming obese from their very childhood. Mothers of such children should keep complete information regarding balanced diet and should take care to ensure that their children develop the right habits of eating and living. Here, in this article we will discuss upon the root factor of fat deposit in the body and how we can restrict it to the normal level. In the human body, fat is present in the form of an independent tissue called adipose tissue. This tissue contains a large number of fat cells. During the first year of a child’s life, the number of fat cells has a tendency to increase. After the age of one year, there is no appreciable change in the number of fat cells. The size of individual fat cells, however, may increase or decrease, depending upon the nature of energy imbalance. Thus, if a child is excessively fat during the first year of his life, the number of fat cells increases rapidly. Later on, fat gets accumulated in these cells and obesity ensues.So the question arises, how to put check on the diet of your child. It is not desirable to impose a big cut on obese children’s diet. In this regard, the treatment of child obesity differs from that of the adults. It is unnecessary to make any efforts to actually reduce child’s weight. It is enough to devise a diet plan that ensures prevention of weight gain. As the child grows, he gradually moves towards his ideal weight. It is also necessary to insure that during his dietary regimen, he gets an adequate supply of vitamins and minerals.Preventive measures against child obesityThe two most important things you have to do in order to prevent your child from being obese are – 1. Plan a diet for your child that contains low carbohydrate, medium fat and high protein food. Exclude carbohydrate foods like cake, ice creams, chocolate, jam, sugar, sweets, etc. 2. Encourage him to participate in sports and other physical activities. This will help him in shedding extra fat from the body.Hazards of childhood obesity Child obesity creates many hazards and disadvantages for children. Some of them are as below – 1. Obese children easily fall a victim to diseases of respiratory system.2. Besides this, the long term dangers include increased serum insulin levels and increased serum cholesterol and triglyceride levels.Disclaimer: This article is not meant to provide health advice and is for general information only.

Skeletal muscle makes up about 40-50% of total body mass, i.e., 28-35 kg in a 70-kg individual. The main constituents of skeletal muscle include water (75%) and protein ( 20%). Of this 20%, the majority is contractile protein (myofilaments) (-11%) with smaller amounts of sarcoplasmic ( 6%) and connective tissue (3%) protein. Of the 20 amino acids that are the component parts of protein, only approximately 50% can be produced in the body-the remainder are called indispensable (or essential) because they must be consumed in the diet or the ability to form body protein (both structural and enzymatic) is compromised. Consequently, the supply of amino acid (type and quantity of protein) in the diet plays a critical role in muscle growth. Historically, as mentioned above, the adequacy of dietary protein has been assessed using the nitrogen balance technique. This involves quantifying nitrogen intake (food protein is ~16% nitrogen) and excretion (urine, feces, sweat, and miscellaneous) as accurately as possible . Dietary protein requirement is determined as the quantity of protein in which nitrogen intake exactly matches nitrogen excretion, i.e., when the individual is at nitrogen balance.

Classically, the daily RDA for protein has been determined by measuring the requirement in a sample that is representative of the population of interest and adding a safety buffer equal to two standard deviations of the mean. Statistically, this should mean that when this quantity of protein is consumed, the vast majority (>95%) of individuals from the representative population would receive an adequate supply of amino acids. This safety buffer is necessary because requirements can vary somewhat among individuals. Many experiments have been completed over the years and, at least in sedentary individuals, it is clear that the requirement for protein is about 0.6 g/kg/day. When the safety buffer is included, the recommendation for protein intake is slightly higher (0.8 g/kg/day). Logically, it would seem that for those attempting to build muscle mass or maintain an increased muscle mass additional protein might be necessary. In fact there are data that support this idea but there is still little consensus on this topic. Further complicating the issue is that the nitrogen status (balance) technique is rather labor intensive and has several other limitations-the major one being its black box approach, i.e., it cannot distinguish whether changes in balance are due to effects on protein degradation/synthesis, or amino acid oxidation, etc.

Another way to investigate the dietary protein requirements involves the use of metabolic tracers which make it possible to see into the “nitrogen status black box” by assessing which components of protein metabolism are affected by an exercise or dietary treatment. This is an improvement when compared with the nitrogen status technique. Some recent data that were obtained using this technique suggest that current amino acid requirements (determined using the nitrogen status technique) may underestimate resting need by 40-90% but these new data remain controversial. In addition, some studies (to be discussed below) indicate that strength athletes can benefit from protein intakes that exceed the current RDA. Recent experiments using both metabolic tracers and nitrogen balance methodologies indicate that the protein requirement for strength athletes is likely about 1.5 g/kg/day, i.e., almost twice the current . When two standard deviations are added, the protein RDA for strength athletes could be as high as 1.7-2.0 g/kg/day. Despite this, it is unlikely that protein deficiencies will be rampant in athletes because it is not difficult to obtain this quantity of protein in one’s diet given the high energy intake of most athletes. For example, even if only 10% of the energy in a 21,000 kg (5000 kcal) diet is protein, an 80-kg individual consuming this diet would receive 1.6 g of protein/kg/day . Typically, the percentage of protein in a US diet is closer to 12-15%.

Every single bodily function depends on an adequate supply of vitamins and minerals in the bloodstream, including the growth process. Nutrition has a major influence on the quality and speed of cell growth, starting in the uterus and continuing into adulthood. Poor prenatal nutrition will not only retard the growth process, but may also lead to birth defects and other physical abnormalities.

Every single bodily function depends on an adequate supply of vitamins and minerals in the bloodstream, including the growth process. Nutrition has a major influence on the quality and speed of cell growth, starting in the uterus and continuing into adulthood. Poor prenatal nutrition will not only retard the growth process, but may also lead to birth defects and other physical abnormalities.The most important group of vitamins in terms of growth and development are the vitamins that make up the Vitamin B complex. The B complex is critical for normal growth in children, as well as many physical and mental bodily functions. One of the vitamins with the B complex, Vitamin B12, is especially important for normal growth in children due to its supply of cobalt. Vitamin B9, also known as folic acid, is probably the most important of the B vitamins while the child is still inside the uterus. Folic acids are known to prevent birth defects and aids in the proper creation of the child’s DNA.In order for a child to grow into a healthy body weight, the thyroid must function properly. The key mineral that aids in thyroid health and development is Zinc. Zinc deficiency is commonly seen in third world countries where diets are usually poor and the crops are grown in poor soil quality which is usually short on Zinc. Because of these factors, the percentage of retarded growth among children is unusually high. Depending on age and weight, children should be consuming between 10 and 15 mg of Zinc every day.

For a child’s bones to grow and develop into normal size and hardness, the most important vitamins and minerals, calcium, phosphorous, Vitamin D, Vitamin C, Vitamin K, Vitamin A, and magnesium, must all be present in sufficient quantity within the body. These vitamins and minerals all have properties that cause them to work as partners in regards to bone structure and density. Taken individually, they will not be as effective as they are when present as a group. Since the bones are continually losing calcium, sustaining the required levels of this group of vitamins and minerals is critical to proper growth.Anyone with children can tell you that it is not always easy to fit all these nutritional requirements into their daily diet. Kids won’t always eat the healthiest foods, and won’t often eat everything you put in front of them. For this reason, dietary supplements may be an easier and more effective way to ensure that your child will grow properly. However, different children have different dietary needs, so always consult with your family doctor before starting your child on a nutritional supplement program.Nancy Dean is a freelance author who has worked in the health care industry for several years.

The main aim of exercising is to improve muscle tone, strength and endurance. This requires the production and use of energy by the body. This energy constitutes complex molecules known as ATP, Adenosine Triphosphate. These ATP Molecules are the essential elements of a biochemical process called the Krebs Cycle or Tricarboxylic Acid Cycle. Carbohydrates break down into sugars that form ATP molecules.

The simpler sugars break down more easily and quickly on an average. However, the more complex carbs take longer to break down and therefore provide the body with an adequate supply of compounds required to produce ATP. It is a known fact that sugars so to speak are not bad for the body but when consumed in excess and in unhealthy forms, can lead to adverse health problems such as Diabetes. ATP molecules are broken down into ADP(Adenosine Diphosphate) and thus release energy in the process. Once the ADP are produced, they pick up the molecules required for the production of more ATP and thus the cycle continues once again.

The energy that is released during this process is used to repair and maintain the damaged cells in the body,aid in the process of respiration, help the organ system function properly and more importantly produce the energy required to fuel muscle contractions.

The Krebs Cycle leads to the production of heat and carbon dioxide as byproducts. The heat is eliminated from the body through the processes of respiration and sweating. Whereas, the carbon dioxide is carried through the system and some of it is expelled during the respiratory process. Exercise which basically involves muscle contractions requires ATP molecules to be produced continuously at different stages in time.

 In order to achieve this the body has the capability of producing 3 different systems, which produce ATP at different rates. The phosphagen system allows ATP to be replenished quickly but only for short periods. Thus this system greatly helps sprinters. The glycogen-lactic system produces ATP at a much slower pace and lasts only for upto 90 seconds or so. The third system is known as Aerobic respiration. This process makes ATP the slowest but can last indefinitely. When you exercise, ATP gets consumed. This is the principle reason why we need to eat in order to replenish the lost nutrients and gain more energy in order to exercise and produce more ATP. Thus, this cycle starts over again.

The body is a fascinating self regulating system that consists of interconnecting components. This structure of the body is central to the way it produces and uses energy.

An adequate supply of macro nutrients and micronutrients are required for survival, growth, and development, and for the maintenance of health and well-being throughout life. Regarding skeletal muscle growth, the accretion of protein (primarily contractile) represents one of the primary goals that a select group of athletes (e.g., bodybuilders, powerlifters, Olympic-style weightlifters) aspire towards. Rates of protein accretion (and loss) are a function of the balance between protein synthesis and degradation. An increase in skeletal muscle mass can occur via an increase in synthesis, a decrease in degradation, or a combination of the two. Note that each process is mechanistically distinct. That is, one can occur in the absence of changes in the other.

Nutritional status and the hormonal milieu present in the body have a profound impact on how protein is used (i.e., oxidized, used to make additional contractile or noncontractile protein, etc.). Various supplements have been touted as muscle-builders” based on the notion that they impact protein metabolism, specifically, via an inhibition of protein degradation. Some of these supplements, it is clear, do in fact ameliorate the decline in protein synthesis seen under certain stressful states; however, protein synthesis may also be affected when these supplements are consumed.

A couple factors must be taken into account regarding the degradation of cellular protein? The half-lives of different proteins vary tremendously between and within cells. Also, proteins do not exist within solution intracellularly but are part of distinct structures (e.g., contractile protein, cytoskeleton, etc.) within the cell. If the integrity of each cell is to be maintained, the degradation of various proteins within a cell must be regulated smoothly. Regarding skeletal muscle, there is evidence that myofibrillar and nonmyofibrillar protein are independently regulated. Thus, when examining the existing data on how various dietary supplements affect protein synthesis and degradation, one must remain cognizant of the fact that wholebody protein synthesis and degradation may (or may not) reflect changes in skeletal muscle protein synthesis and degradation.

The supplements that this chapter will cover are those that have been touted as anticatabolic. It would seem plausible that a decrease in protein degradation with no change in protein synthesis should result in the accumulation of extra protein. This of course would be particularly important for athletes involved in the strength-power sports (i.e. bodybuilding, powerlifting, Olympic-style weightlifting, shot put, discus throw, etc.)

Looking For A Calcium But Not Sure Which Is Best For You?

Calcium is essential to good health, but if you are looking for calcium it can be confusing to decide in which form you take it. There are so many available and every one claims to be good for you, so why the difference? Why not just sell the best and let us all know what it is? Well, this same argument could be applied to all supplements that are sold in different forms, and also to many foodstuffs.

The supplement best for you might not be the best for the next person due to dietary requirements each persons diet is different, so it is better to learn about what is available then make your choice based upon knowledge rather than ignorance. It is not only the source of the calcium you have to bother about, but also the other vitamins that have be present to make sure that that the calcium is absorbed by the body in the way that you want it to be.

To understand that then you need to learn why the body needs calcium, other than just the bones and teeth that everybody knows about. After all, why else do we need calcium? It is only contained in bones and teeth right? Wrong!

Although 99% of calcium is contained in your bones and teeth, 1% is contained in the blood, muscles and central nervous system. With out that 1% we would all die. Without teeth we would not. Calcium is essential for blood clotting and for the proper function of our muscles, brain and central nervous system. Calcium combines with phosphorus to create healthy bones and teeth, and is essential early in life to build up a strong skeleton. Note that phosphorus is also necessary so we also need an adequate supply of that mineral.

Calcium is essential to allow muscles to properly contract. Without that ability, muscles could not work, and a deficiency of calcium causes muscle cramps and spasms. The movement of the smooth muscles is regulated by a protein that is bound to calcium. This is just one of the uses of the calcium in the body that most people are unaware of.

Calcium also takes part in the binding process of the blood platelets during the coagulation of blood. Although most people are aware of the need for vitamin K and fibrin, in fact calcium is also essential in its interaction with the platelets in the coagulation cascade that eventually results in a blood clot that stops bleeding. Basically, without calcium, the blood could not form a clot. In addition to its effect on blood clotting, calcium also plays an essential part in the movement of ions through the membranes of nerve cells, and without it intercellular communication could not occur. Our nerve impulses would not occur and the body again would not be in a working condition.

However, the body has a way of modulating the calcium level in the blood past a minimum level needed for effective nerve cell communication, and below a certain level it can even use the calcium in the bones to divert to the more needy areas of the body. It is therefore not possible for the body to fail through a lack of calcium. The skeleton would disintegrate first. Nevertheless, nobody wants a disintegrating skeleton since that would be counterproductive to effective movement of the body, so a good source of calcium is essential for overall bodily health, not just that of the teeth and the bones.

There are many sources of calcium, but some are more suitable for absorption by the body than others. Chalk, or calcium carbonate, is an excellent source of calcium, but will fail to promote bone growth if your diet does not contain sufficient potassium, vitamin D, magnesium and strontium needed to make it work to build healthy bones. It is the most common on the shelves, and likely the cheapest, but not necessarily the best source. It is basically chalk or limestone, and only 10% of the supplement will actually become available for your body to use.

The bioavailability of a calcium supplement is a figure that indicates how much of the calcium is actually absorbed by the body during digestion. It is important that the supplement is digested and absorbed properly or the calcium will not be available for use. This availability is called the bioavailability. Calcium citrate has a bioavailabilty of 50%, but the size of the citrate part of the molecule is so large that only 10.5% of the molecule is available to the body as calcium. Not much more than the carbonate.

Calcium aspartate is highly soluble and produced by reacting calcium with aspartic acid to form the soluble salt. It is much easier to assimilate and be absorbed by the body than any of the forms above. The amino acid, aspartic acid, delivers the calcium exactly to where it is needed, where it is absorbed and used. Although a bioavailability figure is not available, it is not the amount of calcium that is significant here but the fact that it comes with its own transportation system and is immediately available where needed.

If you want to calculate the availability for yourself, find the molecular weight of the particular calcium product, and then the weight of the calcium contained within it. For example, in calcium carbonate, CaCO3, the molecular weight is 100 (40 + 12 + 3×16) and the atomic weigh of calcium is 40, so the amount of calcium present in 1000g calcium carbonate is 40% or 400g. Only 25% of calcium carbonate is absorbed, so only 10%, or 100g, of calcium is available for each 1000g supplement.

Calcium citrate on the hand (Ca3(C6H5O7)2.4H2O) has a molecular weight of 570, so the amount of calcium present is 3*40*100/570 = 21%. Since the bioavailability of calcium citrate is 50%, the amount of calcium available is only 10.5%, or 105g in 1000g citrate. You can carry out the same calculation on all the molecules if you know how much is absorbed by the body.

The bioavailability is calcium aspartate is 85%. Its molecular formula is [C4H6NO2]2Ca, and molecular weight 304. The calcium availability is therefore 40*100/304 = 13.16%. If 85% is absorbed, then 1000g provides 80% of 13.16 x 10 = 115.6g. The aspartate therefore wins it.

Amino acid chelates can also be used as a source of calcium, and its bioavailability is improved tremendously by including vitamin D and magnesium in the supplement. The bioavailability of these calcium chelates are not quoted, but is claimed to be high. Whether or not it is as high as the aspartame is debatable, though it is claimed to be.

Calcium is a very important mineral for human health, and there are several different supplements that can be used. The bioavailability of the calcium is different in each supplement, though the organic forms, calcium aspartate and amino acid calcium chelates appear to be the highest. When looking for a calcium supplement look for one with additional minerals added as mentioned above to help improve absorption and usability by the body.
