Also to know is, what vitamins are synthesized in humans?Humans are able to synthesize certain vitamins to some extent. For example, vitamin D is produced when the skin is exposed to sunlight; niacin can be synthesized from the amino acid tryptophan; and vitamin K and biotin are synthesized by bacteria living in the gut.Beside above, can vitamin D be made in the body? The liver and kidneys convert vitamin D (produced in the skin and taken up in the diet), into the active hormone, which is called calcitriol.
