🧪 Formulation Notes

100% solar production zero-carbon footprint

100% solar Protected for optimum absorption

100 mcg natural methyl B12 plus complete B-complex

Andrew Lessman's vitamin B12 100 delivers an exceptionally high potency (100 mcg) of our unique absorption-protected methylcobalamin (natural coenzyme Vitamin B12). Among the B-vitamins, B12 is not just the most important from a functional standpoint, but also because of its limited availability from the diet and extremely difficult absorption. Vitamin B12's challenged absorption stems from its unusually large size and complex molecular structure. Vitamin B12 is essential for energy production, including carbohydrate and fat metabolism, as well as the creation of hemoglobin, without which, vital oxygen cannot be transported throughout the body. Vitamin B12 is also required for the synthesis of our genetic material (DNA and RNA) and is therefore required for normal cell growth and development. Vitamin B12 supports heart and brain health by supporting homocysteine metabolism. Typical supplements deliver Vitamin B12 in the highly inferior, unnatural form of cyanocobalamin. As its name implies, cyanocobalamin can deliver trace amounts of cyanide – an undesirable toxic chemical. No quality product would use cyanocobalamin. The large molecular size of Vitamin B12 makes it highly susceptible to destruction in the digestive system, which is why our natural methylcobalamin is protected from stomach acid so it can release its benefits in the small intestine where it can be absorbed. It is the most intelligent and effective way to orally deliver B12's benefits. It is well-established that stress, aging and digestive issues reduce B12's already poor absorption, so given its critical functions, one should carefully consider supplementing this difficult to find and hard to absorb vitamin.

Our Vitamin B12 overcomes all of the problems of typical B12 supplements and insures the benefits you seek in a small, easy-to-swallow capsule that is gentle to even sensitive stomachs.

Contains no additives or common allergens Contains no milk, soy, yeast, corn, wheat, gluten, sodium, salt, sugar, fat, cholesterol, color, preservative, common allergens, genetically modified (GMO) ingredients or manufacturing additives.
