Vitamin E is a fat-soluble vitamin that exists in eight different forms. Each form has its own biological activity, the measure of potency or functional use in the body. Alpha-tocopherol is the most active form of vitamin E in humans, and is a powerful biological antioxidant. Antioxidants such as vitamin E act to protect your cells against the effects of free radicals, which are potentially damaging by-products of the body's metabolism. Free radicals can cause cell damage that may contribute to the development of cardiovascular disease and cancer. Studies are underway to determine whether vitamin E might help prevent or delay the development of those chronic diseases.

Vitamin A or retinol has a structure depicted to the right. Retinol is the immediate precursor to two important active metabolites: retinal, which plays a critical role in vision, and retinoic acid, which serves as an intracellular messenger that affects transcription of a number of genes. Vitamin A does not occur in plants, but many plates contain carotenoids such as beta-carotene that can be converted to vitamin A within the intestine and other tissues.

Vitamin D is ... made in the skin when it is exposed to sunlight. In the white race, as little as 15-20 minutes a day in the sun creates enough vitamin D in the skin for the body's use. The more pigment there is in the skin, the less sunlight gets through so that deeply pigmented and black individuals create little vitamin D. A quart of vitamin D fortified milk a day is enough. However, prolonged intake above 2000 IU a day can cause toxic effects. The recommended dose is 400 IU a day. Check your sunlight exposure, your milk intake and the amount of vitamin D in your multivitamin preparation.

Vitamin C is ... known as ascorbic acid, because it is the "anti-scorbutus" vitamin (scorbutus being the Latin name for the disease of scurvy). Unlike other vitamins, it is only required by a few species, particularly humans, but also guinea pigs and bats. Others, such as dogs and cats, make it for themselves by oxidizing glucose. Species that require the vitamin have lost the key enzyme that manufactures vitamin C because of a genetic mutation during evolution, in a period when the natural diet was vitamin C–rich, resulting in no disadvantage. The empirical formula of the vitamin is C6H8O6; it is a white crystalline powder, freely soluble in water and pleasant tasting, but easily destroyed by heat and oxidation. A daily intake of as little as 7 milligrams (mg) has been found to be sufficient to prevent the development of signs of scurvy, but the usual recommendation is that adults should aim to take some 70 mg per day, partly as a safety factor.
