B12 Methylcobalamin · 1000 mcg

- Methylcobalamin is the active form of vitamin B12 for maximum benefit.
- Higher bioavailability than the most common form, cyanocobalamin, which does not convert to a sufficient amount of methylcobalamin to correct certain forms of anemia, neurological defects and aging1.
- Reduces homocysteine ​​levels for protective effects on the cardiovascular system
- Sublingual tablets provide rapid action directly into the bloodstream.
Vitamin B12 is the cofactor of enzymatic reactions with various physiological functions. It is necessary for the conversion of methylmalonyl CoA to succinyl CoA, as well as the conversion of homocysteine ​​to methionine by methionine synthase, which is then converted to S-adenosylmethionine. B12 deficiency leads to deficiencies in these two pathways, disrupting neurological function, including poor formation of myelin sheaths, production of toxic levels of homocysteine, and inefficient energy production in all cells.
Methylcobalamin, the major circulating form of B12 and the one that is transported to peripheral tissues, has been shown to reduce not only homocysteine, but also inflammatory factors and carotid artery plaque volume in stroke patients, as well as pain and neuropathy in diabetics. Because of its relationship with myelin production and neurological function, high dose B12 has been used in a variety of neurodegenerative diseases, including Parkinson's disease, amyotrophic lateral sclerosis, and multiple sclerosis.
Some people, especially those with malabsorption or low dietary intake, are at higher risk of B12 deficiency. People with poor B12 absorption rely on passive absorption, which is typically 1% of the amount ingested. Therefore, high doses may be necessary for people with greater B12 needs, such as the elderly and those with neurodegenerative disorders.
