Water soluble vitamins:

Vitamin C (Ascorbic Acid)
Vitamin C also known as, ascorbic acid, L-ascorbic acid, dehydroascorbic acid, the antiscorbutic vitamin, L-xyloascorbic acid and L-threo-hex-2-uronic acidy-lactone, is a much talked about vitamin, with people claiming it as a cure-all for may diseases and problems – from cancer to the common cold.

Vitamin P – bioflavonoids
Bioflavonoids also called Vitamin P are not strictly speaking a vitamin, but for easy classification, i am listing it as a vitamin. The term bioflavonoids refers to many different ingredients and include hesperin, hesperidin, eriodictyol, quercetin, rutin etc. This nutrient can not be manufactured by the body and must be supplied in the diet.

Vitamin B Complex
Vitamin B1 – thiamine, thiamin
Thiamin, also called vitamin B1, is used in many different body functions and deficiencies may have far reaching effects on the body, yet very little of this vitamin is stored in the body, and depletion of this vitamin can happen within 14 days.
Thiamin is also a miraculous nutrient, somebody suffering from beriberi, scarcely able to lift their head from their pillow, will respond quickly from injected thiamin, and will be on their feet within a matter of hours.

Vitamin B2 – riboflavin
Riboflavin (vitamin B2) is manufactured in the body by the intestinal flora and is easily absorbed, although very small quantities are stored, so there is a constant need for this vitamin.

Vitamin B3 – Niacin, Niacinamide, Nicotinic Acid
Niacin also called nicotinic acid, niacinamide or nicotinic acid and referred to as vitamin B 3, which can be manufactured by the body. Niacin is derived from two compounds – nicotinic acid and niacinamide.

Vitamin B5 – Pantothenic Acid
Pantothenic acid, also known as vitamin B5, as well as the “anti-stress vitamin” is part of the B group vitamins and classified as a water-soluble vitamin. This nutrient can be manufactured in the body by the intestinal flora.

Vitamin B6 – Pyridoxine
Vitamin B6, also known as pyridoxine is part of the B group vitamins and is water-soluble and is required for both mental and physical health.

Vitamin B9 – Folacin, Folic Acid
Folic acid, also known as Vitamin B9, is also referred to as folacin or folate and its chemical name is pteroylglutamic acid. This vitamin can be manufactured by the body and be stored in the liver.

Vitamin B12 – Cyanocobamin, Cobalamin
Vitamin B12, known as cyanocobalamin, cobolamin and also known as the energy vitamin is a very widely researched vitamin, and used in supplementation to a very large degree.
This complex structured compound with its cobalt content forms part of the B group vitamins, and the body needs very small amounts.

Vitamin H – Biotin
Biotin, as referred to as Vitamin H is part of the Vitamin B complex group and might be interesting to some people since one of the most visible symptoms of shortage of this vitamin is thinning of hair which can lead to total hair loss.
This does not mean that baldness is a sign of Vitamin H in short supply – severe hair loss might just be indicative of biotin being deficient.

PABA – Para-aminobenzoic acid
PABA is the shortened name for para-aminobenzoic acid that is often thought of as only an ingredient used in sunscreens, while it is in actual fact a nutritional ingredient as well. Since it is a moiety of PGA, a form of folic acid, some health professionals do not consider it a vitamin, but only a B-complex factor.

Choline
Choline’s metabolism is closely interrelated to that of methionine, and methyl-folate, yet choline is at times treated by some nutritional specialists as a stepchild in nutrition.

Inositol
Inositol is needed for health at cellular level and a fair concentration is found in the lens of the human eye as well as the heart.
Men taking extra inositol reported that their hair loss had improved, with less hair falling out – although this has not been tested under clinical situations.
