Beta Carotene Is The Safe Form Of Vitamin A

Beta Carotene Is The Safe Form Of Vitamin A

The fact that beta carotene is stated to be a safe form of vitamin A suggests that vitamin A is in some way unsafe. In fact an overdose of vitamin A can lead to any one of a number of conditions, including nausea, jaundice, vomiting, abdominal pain and headaches. This vitamin is fat soluble, and so any excess is not easily washed out of the body but can build up in the tissues. Toxicity in the liver can occur at fairly low concentrations, and the toxicity of the vitamin is increased by excessive alcohol intake. However, toxicity only occurs with vitamin A already formed such as that obtained from liver. There are several forms of vitamin A, including the retinoid form originating from animal sources and the carotenoid forms that have a vegetable origin. Carotenoids are converted to vitamin A in the liver, but the higher the concentration of beta carotene in the body, the smaller the percentage that is converted to vitamin A, so beta carotene is a safer source of vitamin A than retinoids. It is only the finished form of vitamin A that is toxic, and beta carotene is therefore self-regulating in its production. This vitamin is stored in the body in the form of the alcohol (retinol) and of retinyl esters. Studies have indicated that as much as 95% if the stored vitamin is in the form of the ester. The liver is responsible for releasing vitamin A to the body as it is required. One of its better known effects is on vision, and the old wives tale that carrots help you to see in the dark has an element of truth in it. In order for it to aid vision, retinol is oxidized to the aldehyde, retinal, that forms a complex with a molecule of opsin, a light sensitive protein found in the retina. Rhodopsin, as the complex is called, is an essential component of the biochemical chain of events that lead to the perception of light. It is extremely sensitive, and enables you see in very low levels of light. In other words it is essential for good night vision, so carrots do help you to see in the dark! When a photon of light hits a molecule of rhodopsin, it leads eventually to an impulse being sent up the optic nerve to the brain. One of its properties is its reaction to white light. When rhodopsin is exposed to white light it loses its pigmentation, and hence its photoreceptor properties and can take 30 minutes to regenerate. That is why you lose your night sight if your retina is exposed to bright light. The more rhodopsin you can generate the quicker you develop night sight. The other biochemical processes of the vitamin include the synthesis of some glycoproteins and maintenance of normal bone density. Without vitamin A, calcium is not properly absorbed by the body and glycoproteins are involved in this process. A deficiency of vitamin A can lead to the abnormal development of bone and other health problems, so there are limits between the levels of vitamin A in the body that must be maintained: above or below these limits will lead to health problems, some of which can be extremely serious. Most of the biochemistry of vitamin A in the liver is initiated by the presence of alcohol, and otherwise it is though to passively store the vitamin until needed when it is released into the blood. There are several ways in which the presence of alcohol allows the liver to deplete its store of retinol, but generally there are a number of enzymes that, in the presence of ethanol, can render vitamin A into a water soluble form that is excreted by the urine. The benefits of vitamin A other than its effect on night sight and the healthy development of bone tissue, includes a powerful antioxidant effect that neutralizes free radicals that can destroy body cells. These free radicals are generated by the body’s metabolism in generating energy from blood glucose, and are also created through exposure to pollutants such as cigarette smoke and traffic fumes. They are electron deficient, so when they are generated they grab an electron from tissue close by which destroys the cells involved. This can lead not only to the appearance of premature aging as the skin cells are damaged but also to serious health problems such as atherosclerosis and some forms of cancer. Vitamin A helps to protect against these by destroying the free radicals before they can do damage. It also helps build up resistance against infections by supporting the immune system. Beta carotene is converted to vitamin A either by cleaving at the center of the molecule, or by breaking it down from one of the ends. This latter process is carried out in the small intestine, and the resultant vitamin stored in the liver in the ester form. Only a proportion of what you eat is converted to retinol ester in this way, and the more beta carotene you consume, the less is converted, so you can never suffer from an overdose of beta carotene-derived vitamin A. It might turn you yellow, but you won’t suffer from excess vitamin A since the excess beta carotene is stored in your body fat, including the subcutaneous fat reserves. Alpha carotene can also be used in the synthesis of vitamin A, but not as actively as beta carotene. The best natural sources are fruits and vegetables, especially the red, yellow and orange varieties such as carrots and apricots, and also the leafy green vegetables, although supplements are also a convenient way of maintaining your beta carotene uptake. It is a much safer supplement than straight vitamin A for the reasons explained earlier. The supplement is not useful just for its antioxidant effect, but also for its ability to protect you from excessive exposure to the sun. While not as effective as a good sun blocker, beta carotene does provide some protection.There is no doubt that beta carotene is a safer way to maintain an adequate vitamin A uptake due to the fact that you cannot take an overdose, since an overdose of beta carotene does not translate into the same dose of vitamin A, and the change is self-regulating. It is therefore safer to obtain your vitamin A needs from colored fruits and vegetables or beta carotene supplements than from eating liver, from which the retinol is in a form that can cause damage in the event of consuming an excess. The old adage that you should never eat polar bear livers is a true one, and certainly has a provable scientific basis, so use beta carotene as your main vitamin A source for maximum health benefits in the safest possible way.

Determine Whether Vitamin A Enhances Immune Response

October 27th, 2008 by admin

Determine Whether Vitamin A Enhances Immune Response

Several approaches have been taken in an attempt to determine whether Vitamin A supplementation enhances immune response and resistance or recovery from infection. In some investigations, researchers have attempted to correlate plasma concentrations of beta-carotene or retinol with immune response or susceptibility to infection. One limitation of this approach is related to the fact that plasma concentrations may have depressed plasma retinol levels as a result of disease. Therefore, it is not possible to establish whether low plasma retinol levels resulted in suppressed immune response or if plasma retinol levels decreased in response to disease or infection. Another approach used is to supplement the diet with retinol precursors and examine immune response at a later time point. This approach may be useful in examining the particular aspects of immunity that may be altered by supplementation, but additional studies are necessary to determine whether these effects have clinical significance in terms of disease outcome. Vitamin A has been fairly well studied in terms of its immunomodulatory effects, and we will review the evidence from randomized controlled trials as well as potential mechanisms of action. Vitamin A supplementation may afford some protection from infection in malnourished individuals, but the potential benefits of supplementation in normal wellnourished individuals remain to be established. There is evidence from several studies that suggests that vitamin A deficiency is associated with depressed immune function and an impaired response to influenza infection. Supplementation of vitamin A is associated with a reduction of mortality and morbidity among certain populations. It appears that populations suffering from malnutrition may benefit from adequate or additional vitamin A supplementation. However, it is less clear if normal, healthy, well-nourished individuals will benefit from additional supplementation with respect to enhanced immunity. The results from several studies involving beta-carotene supplementation in the diet of healthy individuals suggest that certain aspects of innate immunity, such as NK cytotoxicity and monocyte production of the cytokine TNFcx, are enhanced. It appears that lymphocyte subsets or the lymphocyte response to mitogens are not altered. In addition, one study of healthy older individuals found that vitamin A supplementation was associated with a reduction in the number of T lymphocytes. Whether these observed changes of immune function in response to supplementation actually result in reduced susceptibility to infection in healthy individuals is not well established. The results from one study demonstrated no association between vitamin A supplementation and incidence of bacterial infection. we are not aware of any long-term, randomized clinical trials that have evaluated the incidence of viral infection in response to supplementation with vitamin A alone. However, several studies have examined the possibility that supplementation with several multivitamins and or trace elements such as zinc, may alter susceptibility to infection. In general, the findings from these studies show no protection from infection in association with vitamin intake, but a slight decrease in the incidence of infection in those individuals consuming supplemental trace elements such as zinc and selenium. At this time, the potential benefits of vitamin A supplementation for healthy well-nourished individuals regarding susceptibility to infection remain to be established. A high beta-carotene intake has also been associated with a reduced risk of cancer. Earlier epidemiological studies suggested a high natural (fruits and vegetables) intake of beta-carotene was associated with reduced risk of cancer. However, more recent studies have not observed any benefit of beta-carotene intake on incidence of cancer and two studies actually observed an increased incidence of lung cancer in those participants consuming beta-carotene supplements. The presence of other carotenoids in fruits and vegetables has been suggested to be the protective factor in regards to cancer incidence in the early epidemiological studies based on the findings from these recent studies, dietary supplementation with high doses of synthetic beta-carotene may be contraindicated for smokers. As a reminder, it has been known for some time that a high intake of vitamin A results in adverse effects (neurologic, dermatologic, musculoskeletal, gastrointestinal, birth defects) and the results from the most recent studies suggest a potential risk of high doses of synthetic beta-carotene in certain populations. At this time it is probably safest to follow the National Cancer Institute recommendations that suggest five or more servings of fruits and vegetables per day. Immune Effects and Exercise We are currently aware of only one study that has examined whether vitamin A supplementation is associated with a reduced incidence of infection in athletes. Several studies have shown that the risk of upper respiratory infection is increased following competition in marathons or ultramarathons However, vitamin A supplementation before marathon competition did not reduce the incidence of infection in the postrace period. Therefore, to our knowledge, vitamin A supplementation has not been associated with enhanced resistance to infection in healthy athletes.

Nature’s Recipe for Turning Back the Clock

Nature’s Recipe for Turning Back the Clock

Women everywhere are now more aware of the anti-ageing process than ever before and as a result the anti-ageing skincare market has rocketed over the past decade. It is now reported to be worth over billions in the UK alone, and scientific ingredients such as pentipeptides and retinol are part of most female’s vocabulary these days.

However, whilst scientists toil in their laboratories to discover and create new weird and wonderful anti-ageing ingredients, Mother Nature has some of her own ingredients that are useful and can be found right before your eyes.

Most women love roses, especially red ones delivered in quantities of twelve by a handsome man! It is also claimed that rose has aphrodisiac properties; however the female love affair with roses may be even more intense if there was more awareness of their secret anti-ageing properties. Rose is packed with antioxidants to help promote smooth and glowing skin and both moisturises and hydrates, so is especially beneficial to dry or mature skin. It is reputed that damask roses grown in Turkey and Morocco have the most concentrated levels of antioxidant, along with the most potent smell - especially if hand-picked at dawn to retain as much fragrance as possible. Many of the anti-ageing products made by natural brands use damask rose as a key ingredient.

Tea is another natural ingredient with anti-ageing properties – both the white and the green varieties. For thousands of years, before its skin therapy benefits were discovered, tea has been made into a refreshing drink. However, more than just a drink, it has been discovered that tea can help protect skin cells – in fact many in the Eastern world refer to white tea as “the fountain of youth”.

Green tea has been hailed as one of the most potent antioxidants around, fighting free radicals in the environment that can cause so much damage to skin. Green tea includes Vitamins A, C and E, as well as tannins, which can help reduce skin puffiness. Green tea becomes most powerful when used in conjunction with its sister, white tea. Clinical studies have shown that white tea can boost the body’s immune function and can help the skin repair itself as well as defending the skin against UVA and UVB damage, and brands such as Origins and Neals Yard now use white tea in certain skincare ranges.

The grape is most famous as the basic ingredient of wine. However, yet again, this plant has anti-ageing properties which are now being harnessed by skincare brands such as Caudalie. Many different parts of the plant have useful properties; grape seed polyphenols contain antioxidants to help neutralise free radicals, whilst Resveratrol is the grapevine’s natural defence mechanism, helping to stimulate cell renewal. In addition an ingredient has just been patented, called Viniferine, which comes from the stalk of the vine and which boosts radiance as well as helping prevent dark age spots.

So, whilst science is playing a role in combating ageing, Mother Nature has also got some fantastic ingredients to help turn back the clock - or at least slow down the ticking!

Acne Scar Effects and Resulting Acne Scar Treatment

Once acne begins to heal, in minor cases, it in noticed that the area where the acne once was has a color, which is red. With the continuation of the healing process this coloration gradually darkens initially and within the next six months lightens slowly and vanishes to have an unmarked and clear skin. These scars are minor acne scars and using products such as Retinol or any other hydroxyl acid will help in fast healing of the area.Unlike the minor out break scars, scars due to nodular or cystic acne are very deep and more discolored. In this case what should be the best plan of action? The treatment in this case very much depends upon a number of factors. These are the severity of the outbreak, type of skin, condition of skin and finally the dermatologists finding and suggestions.Chemical peels:Chemical peels happen to be the most viable and effective treatment for minor acne outbreak cases. In this treatment method, chemicals are applied on the skin. These chemicals injure the skin around the dried acne temporarily and help in the growth and regeneration of new skin. This procedure needs to be repeated a number of times to obtain favorable results. The successive treatments sessions need to be spaced such that the skin has gets sufficient time to heal itself.Dermabrasion and Laser Resurfacing:Dermabrasion and laser Resurfacing are very effective treatments for acne scars that are light or shallow. In dermabrasion, the skin layers are removed which helps in the development of a new skin layer free of blemishes. The scar marks are thus removed with the old skin and the new skin will grow blemish less. Dermabrasion is most effective when there is no acne as well as no other skin infection. There are various types of dermabrasion, superficial and deep dermabrasions are important among them. Deep dermabrasion removes the epidermis layer from the skin and reaches the dermis layer. This type of dermabrasion requires a longer healing time because the skin has to now generate a whole new protective epidermis layer.A high beam of light with CO2 is used to burn off the top most layer (epidermis) of the skin in laser resurfacing. This layer has most of the scars, so removing this layer removes the majority of scars when a new top layer is formed. Laser resurfacing is a very effective method but the person undergoing this treatment needs care during recovery, as the risk of infection is very high.Surgical Method:The deep scars left by acne are deep ice pick, box scar or rolling acne scar. There are various surgical methods for treatment for such kinds of scars. A punch tool is used to extract the skin inside a deep scar and sew it. This creates a level surface on the skin. This method is called punch excision. Often bands of fibrous tissues are formed under the skin due to deep acne scarring. It is important to break this band. This is done by minute subcutaneous incisions. After healing, this treatment has great effect in reducing or completely doing away with the rippled skin caused by the deep acne scars. Every acne scar treatment has its own positive and negative point. Consult your doctor and dermatologist for the right advice. Beside the above-mentioned measures, there are many other treatments that are known to effectively help the problem of acne. Each case is unique in its own way. The treatment depends upon the type of scar you have.

Large Pores Treatment – 3 Proven Ways to Get Rid of Large Pores for Good

October 24th, 2008 by admin

There are two primary reasons large pores show up on your face – age and genetics. While neither of these factors can be altered or reversed, there are some things you can do to get rid of large pores for good. The verdict is still out on whether large facial pores can be eliminated permanently, but it’s something that has to be taken on a case-by-case basis. Using the methods below, you can at east expect to dramatically shrink your large pores so they are less noticeable.

So, let’s begin.

Harness the Power of Vitamin C and Retinol

Using a mild face wash or topical medication that contain either vitamin C or retinol can work wonders when it comes to reducing large pores. The antioxidants in these items remove dirt and oil form your pores while helping your skin to produce more elastin and collagen.

Exfoliate Regularly

Exfoliation can be accomplished in one of three ways – at a dermatologist, spa, or at home. You can use a simple facial scrub to exfoliate from home and shrink large pores. You may also want to consult your local dermatologist or spa for a microdermabrasion treatment. Microdermabrasion is one way to gently remove dead layers from the surface of your skin and get rid of large pores. Be careful, though. This treatment can be harsh because it basically involves sanding your skin with a rotating wire or steel brush. Ouch!

Use a Chemical Peel Treatment

A facial chemical peel is perhaps one of the best ways to get rid of large pores. You can visit your dermatologist’s office for a chemical peel or you can do it at home. The average chemical peel administered by a dermatologist is going to cost you anywhere between $300 to $2000. On the other hand, you can find at home chemical peels of the same quality for as low as $80 and as much as $660 for more advanced kits. Choosing the at home route, you end up saving $220 to $1,340.

Important Facts about Vitamins

October 18th, 2008 by admin

Are you aware of the fact that vitamins cannot be manufactured by the body? Vitamins need to be supplied by the diet or in some cases through supplements. However, the most natural and better sources of vitamins is through the food you eat. It is essential that the body is supplied with the regular and adequate amount of vitamins for it to function properly and effectively. Vitamins are essential nutrients for normal growth, and general health. A person with adequate supply of vitamins in the diet faces less danger of encountering health-related concerns.

Other functions of vitamins include metabolism regulation, conversion of fat and carbohydrates into energy, and bone as well as tissue formation.

Two Vitamin Categories

Fat soluble vitamins
Fat soluble vitamins are absorbed from the small intestines together with dietary fat. These vitamins are chiefly stored in the liver and stores of fat while waiting for the time when the body needs it. These vitamins can be identified by the mnemonic “ADEK”, which means vitamins A, D, E, and K.

Functions of fat soluble vitamins
Vitamin A also known as retinol is responsible for bone, teeth, and skin formation. On the other hand, Vitamin D (calciferol) helps calcium absorption in the GI tract. Vitamin E, also known as tocopherol promotes healthy circulation responsible for maintaining the special glow of the skin.

Water soluble vitamins
Vitamins B and C are water soluble vitamins. These vitamins are not stored in the body; the reason why replacement or replenishment is necessary on a daily basis due to the fact that these vitamins excluding Vitamins B6 and B12 are excreted in the urine without substantial storage.

Functions of water soluble vitamins
These vitamins have a variety of noteworthy and important functions in the body including working as coenzymes in supporting get energy from the diet or the food you eat. In addition to this vital function, they also contribute to formation of red blood cell, stimulating appetite, good vision, healthy and glowing skin, and healthy nervous system. Due to its multiple functions, have adequate supply of these vitamins in the diet is a great necessity. In cases of insufficiency, vitamin supplementation can fulfill the inadequacy.

Vitamins for your diet:

Weight Loss With Vitamin B
Vitamins B3 and B6 supply the fuel needed to the cells, and help them burn the energy increasing our metabolism rates.
Taking zinc along with B6 pills, it will make our pancreas function better, and this is necessary to digest food consumed.
B2 (Riboflavin), B3 (Niacin) and B6 are for the thyroid functioning normally; deficiencies could lead to sudden weight gain.
For energy production and controlling the fat metabolism in our system, we need Vitamin B5.
Some of the Vitamin B rich foods are wheat grains, nuts, barley, cabbage oats, chicken and even yogurts.

Diet With Vitamin C
This Vitamin helps our body in more ways than one, from keeping our system strong to conversion of glucose from food into energy, it does it all.
Consumption of bell peppers, oranges, grape fruit and lemons are all good sources of this vitamin.
This vitamin helps control by burning the sugar and other food items into calories and energy.

Weight Reduction With Choline
Part of the Vitamin B family, it is required for body to burn fat metabolism and avoid accumulation of fat in our liver.
Egg yolks, cucumber, wheat germ are good sources of this.
Losing Weight With Calcium
Said to be very effective in weight loss, calcium helps keep our bones strong and in fighting reducing risk of gaining weight.
Milk, cheese, yogurt are good sources of Calcium.

Vitamins are life-giving substances. This is the primary reason why adequate amounts should be supplied to the body; either through natural food sources or vitamin supplements. However, there are cases, especially with fat-soluble vitamins where excess amounts would bring negative effects. As always, it is but wise to consult first with the doctor before you decide on which vitamin supplements to take. Do not self-medicate.

Acne Scar Effects and Resulting Acne Scar Treatment

October 15th, 2008 by admin

Once acne begins to heal, in minor cases, it in noticed that the area where the acne once was has a color, which is red. With the continuation of the healing process this coloration gradually darkens initially and within the next six months lightens slowly and vanishes to have an unmarked and clear skin. These scars are minor acne scars and using products such as Retinol or any other hydroxyl acid will help in fast healing of the area.

Unlike the minor out break scars, scars due to nodular or cystic acne are very deep and more discolored. In this case what should be the best plan of action? The treatment in this case very much depends upon a number of factors. These are the severity of the outbreak, type of skin, condition of skin and finally the dermatologists finding and suggestions.

Chemical peels:

Chemical peels happen to be the most viable and effective treatment for minor acne outbreak cases. In this treatment method, chemicals are applied on the skin. These chemicals injure the skin around the dried acne temporarily and help in the growth and regeneration of new skin. This procedure needs to be repeated a number of times to obtain favorable results. The successive treatments sessions need to be spaced such that the skin has gets sufficient time to heal itself.

Dermabrasion and Laser Resurfacing:

Dermabrasion and laser Resurfacing are very effective treatments for acne scars that are light or shallow. In dermabrasion, the skin layers are removed which helps in the development of a new skin layer free of blemishes. The scar marks are thus removed with the old skin and the new skin will grow blemish less. Dermabrasion is most effective when there is no acne as well as no other skin infection. There are various types of dermabrasion, superficial and deep dermabrasions are important among them. Deep dermabrasion removes the epidermis layer from the skin and reaches the dermis layer. This type of dermabrasion requires a longer healing time because the skin has to now generate a whole new protective epidermis layer.

A high beam of light with CO2 is used to burn off the top most layer (epidermis) of the skin in laser resurfacing. This layer has most of the scars, so removing this layer removes the majority of scars when a new top layer is formed. Laser resurfacing is a very effective method but the person undergoing this treatment needs care during recovery, as the risk of infection is very high.

Surgical Method:

The deep scars left by acne are deep ice pick, box scar or rolling acne scar. There are various surgical methods for treatment for such kinds of scars. A punch tool is used to extract the skin inside a deep scar and sew it. This creates a level surface on the skin. This method is called punch excision. Often bands of fibrous tissues are formed under the skin due to deep acne scarring. It is important to break this band. This is done by minute subcutaneous incisions. After healing, this treatment has great effect in reducing or completely doing away with the rippled skin caused by the deep acne scars.

Every acne scar treatment has its own positive and negative point. Consult your doctor and dermatologist for the right advice. Beside the above-mentioned measures, there are many other treatments that are known to effectively help the problem of acne. Each case is unique in its own way. The treatment depends upon the type of scar you have.
