Description
Natural Factors Methylcobalamin B12 provides the superior, biologically available, bioactive form of vitamin B12. This essential nutrient helps prevent vitamin B12 deficiency, is vital for the formation of red blood cells, and assists in the normal function of the immune system and energy metabolism in the body. This convenient, one-per-day, sublingual formula provides 5000 mcg of methylcobalamin per tablet and is suitable for vegetarians, gluten free, and non-GMO.
Methylcobalamin is a coenzyme form of vitamin B12. A coenzyme is a naturally occurring compound, such as a vitamin or mineral, that partners with specific enzymes to help maintain the body’s ability to metabolize nutrients. Preformed coenzyme forms of B vitamins, including methylcobalamin, offer immediate, direct nutritional support, even for those with genetic differences that impair metabolism of standard B vitamins.
Natural Factors Methylcobalamin B12 is offered in a sublingual tablet – no need for injections or to swallow pills! This advanced formula is ideal for anyone who wants the highest quality, most bioactive form of this key nutrient to prevent B12 deficiency and help maintain good health.
Frequently Asked Questions
What is Natural Factors and is it a reliable Canadian supplement brand?
Natural Factors is one of Canada's largest supplement manufacturers, founded in 1955 by Jack and Rona Katz in British Columbia and still 100% Canadian family-owned. The company controls every production stage from raw material sourcing to finished product. Its facility holds TGA certification from Australia's Therapeutic Goods Administration, one of the world's strictest supplement manufacturing standards. All products are ISURA certified — independently tested for 800+ contaminants including pesticides and heavy metals — and Natural Factors conducts four rounds of product testing, double the industry average of two.
What sets Natural Factors apart from other supplement brands?
Natural Factors' most distinctive quality is vertical integration: the company grows its own raw herbs on 1,000+ acres of certified organic farmland in BC's Okanagan Valley, then processes and manufactures in-house. Most supplement brands source raw materials from external suppliers with no direct agricultural control. Natural Factors also uses ISURA third-party testing, a Canadian standard that screens for over 800 contaminants, well beyond typical heavy-metal panels. B Corp certification further reflects a documented commitment to environmental and social accountability, not just a marketing claim.
What makes Natural Factors different from other Canadian supplement manufacturers?
Natural Factors holds TGA certification from Australia's Therapeutic Goods Administration — one of the world's most rigorous pharmaceutical manufacturing standards, rarely earned by Canadian brands and far exceeding most North American certification requirements. Its ISURA testing program screens every product for 800+ contaminants, and it conducts four rounds of quality testing per product versus the industry standard of two. The company also operates its own farm in the Okanagan Valley for select botanical ingredients — a level of vertical integration uncommon among supplement manufacturers — and has been family-owned for over 70 years.
