It is the most famous vitamer of the family, because it is chemically the most air-stable, and it is the easiest to crystallize and therefore easiest to purify after it is produced by bacterial fermentation.

Vitamin B12 neuropathy, involving the degeneration of nerve fibres and irreversible neurological damage, can also occur. D.Particle Size: 100% pass 80mesh
