SAM-e is an
important physiological agent formed in the body by combining the essential
amino acid methionine with adenosyl-triphosphate (ATP). It is involved in
over 40 biochemical reactions in the body. SAM-e functions closely with
folic acid and vitamin B12 in methylation reactions- the process of adding
a single carbon unit (a methyl group) to another molecule. It is many times
more effective in transferring methyl groups than other methyl donors. Methylation
reactions are critical in the manufacture of many body components, especially
brain chemicals, and in detoxification reactions. The New York Times called
SAM-e "a gentle remedy" and "a rival of Prozac". According
to evidence documenting SAM-e's anti-depressant abilities SAM-e is an even
better antidepressant that St. John's wort. In double-blind clinical studies
between 1973 and 1987, SAM-e was proven superior to tested placebo.
Among those typically deficient in tissue levels of SAM-e are the elderly
and patients suffering from osteoarthritis, depression, and various liver
disorders. A deficiency of methionine, vitamin B12, or folic acid can result
in this decreased SAM-e synthesis. However, high supplemental doses of methionine
neither increase associated levels of SAM-e, nor provide equivalent pharmacological
activity. They are also associated with some degree of toxicity. As of this
writing, supplementation with SAM-e appears to safely and effectively treat
these conditions. SAM-e is also used in the treatment of fibromyalgia and
migraine headaches.
