Vitamin U and acne, dandruff and eczema
Acne, dandruff and eczema are skin conditions the origins of which are often idiosyncratic and mysterious. However, one characteristic shared by all three conditions is low glutathione levels. Glutathione is by far the most important antioxidant in the human body, yet we absorb little of it from our food- that's why our body makes it.
There are three main causes of low glutathione -
1. A medical condition that drains large amounts of glutathione
2. A genetic block that prevents the biosynthesis or regeneration of glutathione
3. Not enough glutathione precursors in our diet
Identifying the root cause of your skin condition is an important first step in the healing process. However, this is easier said than done. Often we just don't know why these conditions happen. Sometimes they can break out suddenly and worsen quickly, particularly under stress. At other times, symptoms can persist chronically for years.
Irrespective of the root cause, restoring your glutathione levels is a vital part of this rebalancing act. Glutathione is a tripeptide comprised of cysteine, glutamate and glycine. Of these amino acids, cysteine is most commonly in short supply. If glutathione levels are low due to dietary factors, it is usually due to a shortage of cysteine. Cysteine is found in protein, especially that derived from animals. Cysteine is also made from methionine, again abundant in animal proteins. These sulfur amino acids are also plentiful in grain proteins. However, some people find that meat/dairy/grain are inflammatory for other reasons like hormones or allergens.
Vitamin U is S-methylmethionine, a soluble nutrient abundant in vegetables and fruit that is converted into methionine by the enzyme BHMT2. There have not been any direct studies into whether Vitamin U has any effect on these three conditions, whether taken internally in the diet or as a supplement, or when applied topically as an active component of a lotion. However, taking Vitamin U can help restore glutathione levels which are low in the tissues affected by acne, dandruff and eczema, so it is quite likely that increasing your intake of Vitamin U will help with these conditions, especially in combination with the identification and removal of triggers of these conditions in you.
A glass of freshly-made vegetable juice every day is an excellent way to boost your Vitamin U intake along with a slew of vitamins and minerals essential for good skin health. For those who prefer a supplement, one capsule per day of Bioremediation's Vitamin U may be a useful alternative.
Take care and good luck,
Vitamin U - A possible natural alternative to N-acetylcysteine (NAC)
NAC is also sold as a dietary supplement as a means of optimizing glutathione levels on an everyday basis. Glutathione is the master antioxidant in the human body, responsible for detoxifying compounds in the liver as well as reacting with reactive oxygen species that are harmful in large amounts. Glutathione differs significantly to other antioxidants (such as Vitamin C) in that it is made by humans. Our body makes glutathione from three amino acids - glutamate, cysteine and glycine. Levels can get low when our diet is short of these amino acids. The rate-limiting amino acid is usually cysteine, which the body can obtain from the diet following the digestion of protein, and also enzymatically from methionine. When cysteine levels in the diet are inadequate, glutathione levels in the body become inadequate, resulting in general inflammation. Most chronic illnesses are characterized as having low glutathione levels and restoring glutathione levels may help reduce inflammation, if not actually reverse the underlying problem.
