Methylcobalamin is the only form of vitamin B-12 found in the brain. The liver is unable to convert the common form of B-12, cyanocobalamin, into an ample supply of methylcobalamin. Sublingual Methylcobalamin supports a healthy brain and spinal cord. ProHealth's Neuro B-12 sublingual delivery system ensures optimal absorption and maximum benefits. Protecting Cognitive Function According to Dr. Paul Cheney, vitamin B-12 is a potent detoxifier of the brain. The supplementation of oral methylcobalamin, the bioactive form of B-12, may support cognitive function. Improving Sleep Patterns A study published in the journal Neuropharmacology showed that methylcobalamin reduced the amount of time subjects slept, while it improved sleep quality and helped subjects awake feeling refreshed, with better alertness and concentration. Part of this effect was due to melatonin management during the daytime, because methylcobalamin supplementation reduces drowsiness by apparently decreasing daytime melatonin levels. In general, supplementation with sublingual methylcobalamin is an effective way to provide the bioactive form of B-12 throughout your entire body for maximum benefits. *These statements have not been evaluated by the FDA.
