Product Description

Product Description

Vitamin K1 is a fat-soluble vitamin that is stable in air and moisture but decomposes in sunlight.    It is a polycyclic aromatic ketone. It is found naturally in a wide variety of green plants, particularly in leaves, since it functions as an electron acceptor during photosynthesis, forming part of the electron transport chain of photosystem. The main type is called phylloquinone, found in green leafy vegetables like collard greens, kale, and spinach. The other type, menaquinones, are found in some animal foods and fermented foods.

Vitamins are organic molecules (or a set of closely related molecules called vitamers) that are essential to an organism in small quantities for proper metabolic function. Essential nutrients cannot be synthesized in the organism in sufficient quantities for survival, and therefore must be obtained through the diet. For example, Vitamin C can be synthesized by some species but not by others; it is not considered a vitamin in the first instance but is in the second. Most vitamins are not single molecules, but groups of related molecules called vitamers. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols.

The term vitamin does not include the three other groups of essential nutrients: minerals, essential fatty acids, and essential amino acids.^[2]

Major health organizations list thirteen vitamins:

• Vitamin A (all-trans-retinols, all-trans-retinyl-esters, as well as all-trans-beta-carotene and other provitamin A carotenoids)
• Vitamin B₁ (thiamine)
• Vitamin B₂ (riboflavin)
• Vitamin B₃ (niacin)
• Vitamin B₅ (pantothenic acid)
• Vitamin B₆ (pyridoxine)
• Vitamin B₇ (biotin)
• Vitamin B₉ (folic acid and folates)
• Vitamin B₁₂ (cobalamins)
• Vitamin C (ascorbic acid and ascorbates)
• Vitamin D (calciferols)
• Vitamin E (tocopherols and tocotrienols)
• Vitamin K (phylloquinones, menaquinones, and menadiones)

Some sources include a fourteenth, choline.
