Methylcobalamin is the most active, bioavailable form of vitamin B-12 and is essential for brain and nervous system function. Methylcobalamin protects the brain from toxins, improves brain metabolism, increases energy production, stimulates nerve cell growth factor, leads to a more restful sleep, and aids in maintaining the proper level of homocysteine.
Other forms of B-12 must be converted by the liver into methylcobalamin for optimal nerve cell function. Most people do not adequately convert other forms of vitamin B-12 into methylcobalamin. For maximum bioavailability and absorption, Methylcobalamin should be dissolved under the tongue, not chewed or swallowed.
