S-adenosylmethionine is available as a nutritional supplement and is also known as:
- Ademetionine, *Adenosylmethionine
- S-Adenosyl Methionine, S-Adenosyl-L-Methionine or S-Adenosylmethionine,
- S-Adenosylmethionine Butanedisulfonate
- S-Adenosylmethionine Tosylate, S-Adenosylmethionine Tosylate Disulfate,
- SAMe or SAM-e,
- Sammy or Samyr,
and abbreviated as:
- AdoMet, SAM-e or SAMe,
S-adenosylmethionine may become depleted with B-vitamin deficiency, chronic inflammation, and has been observed to decrease with age.
Theory[edit | edit source]
SAMe may help people with ME/CFS by restoring methyl donor levels, allowing methylation reactions to continue at a normal rate. If there is a deficiency of methyl donors in the central nervous system, SAMe supplementation might be expected to improve some brain function, or improve mood. Among many other synthetic reactions, SAMe aids in the synthesis of the neurotransmitters norepinephrine, dopamine, and serotonin.
Evidence[edit | edit source]
A small number of studies have been conducted in fibromyalgia patients which showed some positive effects when taking SAMe. The main positive effect has been described as a reduction in pain levels. However, Volkmann et al (2009) found no significant effect in a ten day trial of fibromyalgia patients.
