An extract from sugar beets and also known as anhydrous Betaine, TMG is a natural polysaccharide and a good source of methyl groups that promotes healthier levels of the powerful pro-oxidant and free radical generator homocysteine. Homocysteine is a toxic end product of the metabolism (methylation) of methionine (an essential amino acid) and is now known to be a leading cause of heart and artery disease. Multiple studies have demonstrated that medium to high levels of plasma homocysteine are associated with increased risk of heart disease, cerebrovascular disease and peripheral artery disease. In one study, daily treatment with TMG, folic acid and choline normalized homocysteine levels in 17 of 19 patients. [Arteriosclerosis and Thrombosis 13(9): pp.1253-60, 1993]

Along with cofactors such as vitamins B6, B12 and Folic Acid, TMG is part of a chemical contingent in the body that works against cancer, heart and neurological diseases, and nearly every age-related disorder.

TMG is a versatile nutrient and provides an intermediary metabolite that can enable a person or animal to function at more optimum mental and physical levels. It aids the body in overcoming a number of adverse health conditions, and is an intricate part of human metabolism. DMG (TMG’s metabolite) has been used as a nutritional supplement for over 25 years. In a broad sense, TMG protects the body from many forms of physical, metabolic and environmental stress.

Applications include
Immune modulation: Improves antibody response, enhances B- and T-cell function, and regulates cytokines.
Viral/bacterial infections: Enhances immune response.
Cardiovascular: Reduces cholesterol and triglyceride levels, helps eliminate hypoxia, improves coronary circulation, decreases angina pain.
Athletic performance: Enhances endurance, improves oxygen utilization, reduces lactic acid buildup, improves muscle recovery.
Autism/epilepsy: Improves verbal communication/social interaction/lethargy, may reduce seizures
Chronic fatigue syndrome: Greater mental alertness and energy, improves immune dysfunction.
Melanoma: Anti-tumor activity, prevents metastasis.
Lupus (SLE): Reduces antinuclear antibodies, modulates cytokine production.

In the liver, TMG transfers one of its three methyl groups to homocysteine, which is then converted into the useful amino acid methionine.

When methylation is working properly, homocysteine is quickly converted back to methionine which is then converted to SAMe (S-adenosylmethionine), which protects the liver and is a natural antidepressant. [Arteriosclerosis and Thrombosis 13(9): pp.1253-60, 1993] [J Inherited Metabolic Disease 17(5): pp.560-5, 1994] SAMe then acts as a methyl donor for DNA: when attached to DNA, methyl groups appear protective, preventing mutated genes from expressing themselves. [Growth, Development & Aging 57(4): pp.261-73, 1993] It may improve health, reduce the risk of genetically induced cancers, and slow cellular aging. Factors that decrease methylation include smoking, alcohol consumption, high fat diets and birth control pills.

TMG supplementation may sometimes produce hyperactivity in autistic children. Folic acid appears to help neutralize this effect at one or two 800mcg tablets. [Autism Res Rev Int 10( 3): 7, 1996]

The usual TMG dose is 500 to 1,000mg per day - roughly equivalent to what a diet high in broccoli, spinach or beets would provide.

If you are using SAMe, though more expensive, try taking 400mg BID. If symptoms fail to improve after three weeks, try increasing your dose to 400mg TID. If symptoms lessen with 400mg BID, you can try to lower the dose to 200mg BID.

NOTE: An inexpensive variety is Betaine HCL which acts as a stomach acidifier and is not practical due to stomach irritation at the doses required to enhance methylation metabolism.
