Arches Tinnitus B12 Formula offers the most scientifically advanced Vitamin B12 compound found anywhere in the world. B12 is important for everyone and especially for those with tinnitus. B12 is supplied as methylcobalamin, the stable form immediately used by the body. Most B12 products use cyanocobalamin, which has to be metabolized by the body before it is in a usable form. A clinical study showed a high prevalence of B12 deficiency in patients with chronic tinnitus. Our B12 formula includes L-methylfolate instead of folic acid. Folic acid must be converted in the body to L-methylfolate before it can be used. About 50-60% of people have a genetic variation that does not allow this process to be completed. Unmetabolized folic acid can lead to serious health problems including a damaged immune system. Only L-methylfolate is immediately available for absorption. L-methylfolate is essential for healthy hearing and cardiac function. It is also necessary for the synthesis of the neurotransmitters serotonin, dopamine and norepinephrine. L-methylfolate deficiency leads to increased risk of cardiovascular disease, stroke, dementia, depression, cancers, and birth defects. Buy the best, most bioavailable B12 formula compound to ensure better health, improved mood and reduced tinnitus.
