Amino acids are the building blocks of protein. S-adenosyl methionine (SAM-e) is a form of the amino acid, methionine that is bonded with ATP, the major source of energy in the body. It works in three biochemical pathways.
How Does Sam-E Work in The Body?
Firstly, SAM-e donates molecules, called methyl groups, to other substances as a way to stabilize the molecules and reduce damage to body tissues. Methylation also forms genetic material, components of the cell membrane, the insulating coating on nerve fibers and brain chemicals. Secondly SAM-e helps to form sulfur-containing amino acids like glutathione. Glutathione is used by the liver to detoxify harmful chemicals.
Lastly, SAMe plays a role in the formation of polyamines. Polyamines are molecules that regulate gene expression. Thus they keep our cell’s growing and replicating at the proper rate.
Health Benefits of Sam-E
SAMe is recommended by natural health practitioners for a variety of conditions including depression, rheumatoid and osteoarthritis, fibromyalgia, cardiovascular damage due to homocysteine, liver toxicity, liver disease, age-related disease, cognitive disorders, and insomnia.
Sam-E Supplements
SAMe supplements are found in capsules. It should always be taken on an empty stomach because the presence of other amino acids, from protein, will decrease the amount that is absorbed.
Cautions & Considerations
Side effects of SAMe include gastrointestinal upset, dry mouth, and restlessness. It should not be combined with other antidepressants, tryptophan, 5-HTP or St. Johns Wort. SAMe should not be used by individuals with bipolar disorder. It should not be used with blood thinners or by people who have active bleeding or blood disorders. Discontinue SAMe 2 weeks prior to surgery or dental work.




Hearing SAMe brought me staight back to organic chemistry class from college! I was proud to remembe that the abbreviation stood for S-adenosyl methionine and that this methionine form is bonded with ATP. I also remembere SAMe's role as a methyl donor and that this can have a beneficial effect because the methyl donation can stabilize molecules as well as insulate cell membranes. Unfortuntely I had forgotten the other two pathways thay SAMe is involved in, so thank you for reminding me that SAMe also 1) helps to form sulfur-containing amino acids like glutathione, an important amino acid for redox and 2) helps in synthesis of polyamines which are important in regulating gene expression. I appreciate the refresher on SAMe and won't be forgetting these realled learnings for some time :)
Hello Rachel,
Happy our article could provide some nostalgia for you! Thank you for sharing your knowledge about Sam-E and we're happy you enjoyed the refresher. As you mentioned, glutathione, one of the most important antioxidants for the body, you can learn more about it here: https://www.nationalnutrition.ca/articles/supplements/glutathione/
Stay healthy & well.
