Vitamin B12, why sublingual, thanks to Dr. Weil !

"Sublingual (under the tongue) tablets and oral spray forms of vitamin B12, both of which are absorbed by the blood vessels in the mouth, are often better for seniors who may have trouble absorbing this vitamin from the stomach.

Vitamin B12 absorption and/or depletion may occur in those who use alcohol excessively; take antibiotics; use stomach-acid controlling drugs, including H-2 blockers and proton pump inhibitors; or take Metformin to treat type 2 diabetes. Nicotine can also lower serum levels of vitamin B12.
In addition, potassium supplements can reduce absorption of vitamin B12, and there is some evidence that vitamin C in supplements can interfere with obtaining the B12 vitamin found in foods."
