SAM-e and Ketamine Therapy | Tovani Health
SAM-e (S-Adenosyl-L-Methionine) (also: SAMe) — Methyl-donor supplement (mood adjunct)
Verdict at Tovani Health
Fully compatible; serotonergic concern applies to prescription combinations, not KAP.
SAM-e and ketamine have no clinically significant interaction. SAM-e has mild antidepressant effects via methylation pathways. The serotonergic combination concern is with prescription SSRIs/SNRIs/MAOIs, not ketamine. Don't start SAM-e during active SSRI or MAOI therapy without your prescriber's involvement.
If you take SAM-e regularly and are considering at-home ketamine therapy, the combination is generally safe at therapeutic doses. This page covers the brief pharmacologic context and what we do at intake.
How SAM-e interacts with ketamine
SAM-e is a methyl donor in many pathways including monoamine synthesis. Limited direct interaction with ketamine pharmacology; the SS concern applies to combinations with prescription serotonergic agents.
What we do at intake
Disclose dose, brand, and reason for use. Do not start SAM-e during active SSRI or MAOI therapy without your prescriber's involvement. KAP can proceed at typical 400-1600 mg/day doses.
Bottom line
SAM-e and ketamine have no clinically significant interaction. SAM-e has mild antidepressant effects via methylation pathways. The serotonergic combination concern is with prescription SSRIs/SNRIs/MAOIs, not ketamine. Don't start SAM-e during active SSRI or MAOI therapy without your prescriber's involvement.
