  • All Known Essential Vitamins

    Vitamins are a group of substances that are needed for normal cell function, growth, and development. There are 13 essential vitamins:

    • Vitamin A (retinol, retinal, 4 carotenoids)
    • Vitamin C (ascorbic acid)
    • Vitamin D (D3 - Cholecalciferol, D2 - Ergocalciferol)
    • Vitamin E (tocopherols, tocotrienols)
    • Vitamin K (phylloquinone, menaquinones)
    • Vitamin B1 (thiamine)
    • Vitamin B2 (riboflavin)
    • Vitamin B3 (niacin)
    • Vitamin B5 (pantothenic acid)
    • Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine)
    • Vitamin B7 (biotin)
    • Vitamin B9 (folic acid)
    • Vitamin B12 (cyanocobalamin)

    Fat-soluble vitamins are stored in the body's fatty tissue: vitamins A, D, E, K

    Water-soluble vitamins - the body must use almost all water-soluble vitamins right away - vitamins B1, B2, B3, B5, B6, B7, B9 and C.
    Vitamin B12 is the only water-soluble vitamin that can be stored in the liver for many years.

Isaac Bashevis Singer

When a human kills an animal for food, he is neglecting his own hunger for justice. Man prays for mercy, but is unwilling to extend it to others. 

Recommended Dietary Allowance RDA

Recommended Dietary Allowance (RDA) - the average daily dietary nutrient intake level sufficient to meet the nutrient requirement of nearly all - ~97% - healthy individuals in a particular life stage and gender group. 

The process for setting the RDA depends on being able to set an Estimated Average Requirement (EAR). If an EAR cannot be set, no RDA will be set. The EAR is the daily intake value of a nutrient that is estimated to meet the nutrient requirement of half the healthy individuals in a life stage and gender group.

The RDA is set at the EAR plus twice the standard deviation (SD) if known (RDA = EAR + 2 SD). If data about variability in requirements are insufficient to calculate a standard deviation, a coefficient of variation for the EAR of 10% is ordinarily assumed (RDA = 1.2 x EAR).

The RDA for a nutrient is a value to be used as a goal for dietary intake by healthy individuals. The RDA is not intended to be used to assess the diets of either individuals or groups or to plan diets for groups.
