In humans there are 13 vitamins: 4 fat-soluble (A, D, E, and K) and 9 water-soluble (8 B vitamins and vitamin C). Water-soluble vitamins dissolve easily in water and, in general, are readily excreted from the body, to the degree that urinary output is a strong predictor of vitamin consumption. [ 47 ]

For all animals, some amino acids are essential (an animal cannot produce them internally so they must be eaten) and some are non-essential (the animal can produce them from other nitrogen-containing compounds). About twenty amino acids are found in the human body, and about ten of these are essential.
Humans require thirteen vitamins in their diet, most of which are actually groups of related molecules (e.g. vitamin E includes tocopherols and tocotrienols): [20] vitamins A, C, D, E, K, thiamine (B 1), riboflavin (B 2), niacin (B 3), pantothenic acid (B 5), pyridoxine (B 6), biotin (B 7), folate (B 9), and cobalamin (B 12). The requirement ...
Animals store vitamin B 12 from their diets in their livers and muscles and some pass the vitamin into their eggs and milk. Meat, liver, eggs, and milk are therefore sources of the vitamin for other animals, including humans. [62] [2] [77] For humans, the bioavailability from eggs is less than 9%, compared to 40% to 60% from fish, fowl, and ...
Unlike the other twelve vitamins, vitamin D is only conditionally essential - in a preindustrial society people had adequate exposure to sunlight and the vitamin was a hormone, as the primary natural source of vitamin D was the synthesis of cholecalciferol in the lower layers of the skin's epidermis, triggered by a photochemical reaction with ...
Humans require thirteen vitamins in their diet, most of which are actually groups of related molecules, "vitamers", (e.g. vitamin E includes tocopherols and tocotrienols, vitamin K includes vitamin K 1 and K 2). The list: vitamins A, C, D, E, K, Thiamine (B 1), Riboflavin (B 2), Niacin (B 3), Pantothenic Acid (B 5), Vitamin B 6, Biotin (B 7 ...
