From the FDA Drug Label

S-Adenosyl-L-methionine Disulfate Tosylate The FDA drug label does not answer the question.

From the Research

S-adenosylmethionine (SAMe) plays a crucial role in maintaining gut health by supporting methylation processes, reducing inflammation, and promoting intestinal barrier function, as evidenced by its ability to decrease bacterial translocation, proinflammatory cytokines, oxidative stress, and apoptosis markers in hepatic ischemia-reperfusion injury 1.

Key Functions of SAMe in Gut Health

  • Supports methylation processes, facilitating numerous biochemical reactions that maintain intestinal barrier function and regulate gut microbiota composition
  • Helps produce phosphatidylcholine, a key component of the protective mucus layer that lines the intestinal wall, preventing leaky gut syndrome
  • Exhibits anti-inflammatory properties, which may help reduce gut inflammation in conditions like inflammatory bowel disease
  • Supports liver function, closely connected to gut health through the gut-liver axis

Maintaining SAMe Levels

  • Dietary sources rich in methionine, such as eggs, fish, and nuts, can help maintain SAMe levels
  • Supplementation with SAMe, typically at doses of 400-1600 mg daily, may be beneficial, but should be discussed with a healthcare provider, especially for those with existing digestive disorders or taking other medications

Recent Studies

  • A 2023 study found that SAMe decreased bacterial translocation, proinflammatory cytokines, oxidative stress, and apoptosis markers in hepatic ischemia-reperfusion injury in Wistar rats 1
  • Another study published in 2012 investigated the effects of SAMe on inflammation-induced colon cancer in mice, finding that SAMe reduced tumor load by approximately 40% 2
