Vitamin B12 Supplements, Methylcobalamin, Adenosylcobalamin, Hydroxocobalamin & More

Vitamin B12, also known as cobalamin, is a water-soluble vitamin found naturally in animal-based foods including meat, fish, dairy products, and eggs, making it a nutrient of particular relevance to those following vegetarian or vegan diets. It is available in several supplemental forms. Cyanocobalamin is the most commonly used synthetic form. Methylcobalamin and adenosylcobalamin are the two naturally occurring, biologically active coenzyme forms. Hydroxocobalamin is another natural form, often used in injectable medicine but also available in oral supplements. Because B12 absorption can be affected by digestive factors, it is also available in formats designed to bypass standard digestion, including sublingual lozenges, oral sprays, liquid drops, and liposomal preparations. Our Vitamin B12 collection covers all of these forms and formats from a wide range of established brands, at a variety of strengths.
