SAMe (S-adenosyl-methionine) is an amino acid derivative normally synthesized
in the body. SAMe is used by the body in three important pathways:
■Methylation (contributing methyl groups to activate certain
molecules)16,17
■The synthesis of polyamines (for cell growth, gene expression, neuronal
regeneration, etc.)18-20
■Trans-sulfuration (synthesis of cysteine, glutathione, and other sulfate
chemicals)21-23
SAMe occurs naturally in the body; it is concentrated in the liver and
brain and is a major methyl donor in the synthesis of hormones, nucleic
acids, proteins, and phospholipids, catecholamines, and other
neurotransmitters, such as dopamine and serotonin. SAMe is required for the
synthesis of norepinephrine, dopamine, and serotonin, and also plays a role
in other intracellular metabolic pathways.24 SAMe facilitates glutathione
usage and maintains acetylcholine levels, which help enhance or maintain
cognitive function and attenuate or prevent aggression of aging and
neurodegeneration.
SAMe levels may become depleted from sickness and age. Supplementation of
the co-factors — folate, trimethylglycine (TMG or betaine), vitamins B6 and
B12, together with SAMe — appears to be an effective method to overcome this
deficiency. There is evidence that SAMe helps to synthesize
phosphatidylcholine, which keeps cell membranes fluid, and is used in the
brain to make the neurotransmitter acetylcholine.16,17,19,22-23,25
In 2002, an agency of the U.S. Department of Health and Human Services
conducted a meticulous evaluation of SAMe. Their findings show the efficacy
of SAMe in helping maintain stable mood and joint function, without any side
effects.26 Since aging people often suffer joint discomfort and
immobilization, SAMe addresses multiple problems people face as they grow
older.18,27-32 In addition, SAMe has multi-modal mechanisms of action that
are used throughout the body, and especially in the liver, which help
maintain liver health. SAMe facilitates healthy methylation enzymatic
processes and boosts hepatic levels of the critical antioxidant glutathione.
When liver function is compromised, glutathione is depleted, which leads to
free radical damage.
