  • Product Detail
FISH POULTRY ANIMAL FEED ADDITIVE VITAMIN B12 PURE POWDER
Vitamin B12, vitamin B12 or vitamin B-12, also called cobalamin, is a water- soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins.
Like all B vitamins, vitamin B12 is a water-soluble vitamin. This means it dissolves in water and travels through the bloodstream. The human body does not store cobalamin. Any excess or unwanted amounts are excreted through urine.
