Vitamin B12, primarily supplied as Cyanocobalamin, is a water-soluble cobalt-containing vitamin essential for DNA synthesis, red blood cell formation, and neurological function. It is produced exclusively by microbial fermentation using specially selected bacterial strains and appears as a dark-red crystalline powder.
Vitamin B12 is the most chemically complex of all vitamins and is naturally found only in animal-derived foods, making supplementation critical for vegetarian and vegan populations. It is widely used in dietary supplements, food and beverage fortification, infant formula, and animal feed premixes. Its high potency means very small quantities are effective, with typical supplement doses measured in micrograms.
