  • zinc supports the pancreas – important for absorption
  • a viable option to sublingual B12 products

In order for vitamin B12 to be absorbed in the gastrointestinal tract, it first needs to be bound in the stomach to a protein called R-protein. In the intestines pancreatic proteases cause the R-protein to release vitamin B12 to bind with intrinsic factor, making it absorbable. Thorne Research's Bio-B12 contains methylcobalamin (an active form of vitamin B12) and 5-MTHF (an active form of folate) in a base of papain. Papain is a potent protein-digesting enzyme from papaya that also results in the release of vitamin B12 from the R-protein, thus facilitating the absorption process.* Zinc picolinate is included for support of the pancreas, which produces other digestive enzymes that facilitate the absorption process.*

Methylcobalamin (an active form of vitamin B12) is essential for recycling homocysteine and the formation of methyl donors involved in cardiovascular function, sleep, blood cell formation, and nerve function.* Most vitamin B12 supplements contain cyanocobalamin; however, the liver must first "detoxify" the cyanide molecule and attach a methyl group to form methylcobalamin from the cyanocobalamin. Methylcobalamin is already in the biologically active, tissue-ready form.* Evidence indicates the body utilizes methylcobalamin more efficiently than it does cyanocobalamin.* Research shows the quantity of cobalamin detected following a small oral dose of methylcobalamin is similar to the amount following administration of cyanocobalamin; but significantly more cobalamin accumulates in liver tissue following administration of methylcobalamin. Human urinary excretion of methylcobalamin is about one-third that of a similar dose of cyanocobalamin, indicating substantially greater tissue retention.*

Suggested Use Take 1 capsule one to three times daily or as recommended by your health-care practitioner.
