S-adenosylmethionine (SAMe)

DOSAGE: 200 mg to 1600 mg per day.


The unique biological properties of SAMe makes it a critical component of a health maintenance program. SAMe is the most effective facilitator of youthful methylation. Published research shows that methylation defects create a variety of agerelated disorders including neuronal and hepatic dysfunction.1-8 Enhancing youthful methylation facilitates healthy enzymatic life processes throughout the body.

Not only can SAMe enhance mood and alleviate melancholy, but it can also protect the joint linings from structural degradation.9-13 Since aging people often suffer joint discomfort and immobilization, SAMe addresses multiple problems people face as they grow older.

An agency of the U.S. Department of Health and Human Services conducted a meticulous evaluation of SAMe in 2002. Their findings show that the efficacy of SAMe is comparable to mainstream medicine in promoting good mood and bone and joint health. The difference, however, is that SAMe is virtually free of the side effects.14

This U.S. government report concluded that SAMe is 80% better in promoting joint comfort. This report also verified that SAMe was as effective as nonsteroidal anti-inflammatory drugs (NSAIDs) in treating bone and joint discomfort. The significance of this finding is that NSAIDs are associated with serious side effects, whereas SAMe provides benefits throughout the body.14

SAMe should be taken with cofactors vitamin B12 and folic acid.15 If you take the Life Extension Mix and/or the Life Extension Booster, you will get these cofactors.

Not all SAMe supplements are created equal. SAMe is an unstable molecule that requires special processing to ensure stability. Analysis of several popular brands of SAMe revealed many of them did not contain what was claimed on the label. (Refer to page 91 for an update about quality control problems with commercial SAMe supplements).
