| Substance | Interaction | What happens |
|---|---|---|
| SSRIs/SNRIs | Contraindicated | SAMe increases serotonin synthesis. Combined with SSRIs: serotonin syndrome and/or manic switch risk. 9/11 bipolar patients developed mania on SAMe. details → |
| Tramadol | Contraindicated | SAMe has antidepressant activity and serotonergic relevance, while tramadol inhibits serotonin reuptake and is a known serotonin syndrome risk drug.... details → |
| MDMA | Conflict | SAMe has serotonergic and mood-elevating activity that can add to MDMA's serotonin release, increasing the risk of serotonin excess when the two are... |
| 5-HTP | Caution | Both SAMe and 5-HTP independently elevate serotonin activity, so combining them stacks two pro-serotonergic mechanisms. Case literature documents... |
| Buspirone | Caution | SAMe has antidepressant effects and evidence of serotonergic involvement, including 5-HT1A pathway activation in preclinical work. Buspirone also... |
| Citalopram | Caution | SAMe has independent serotonergic and antidepressant activity. Combined with citalopram, the additive serotonergic effect raises the risk of... |
| Duloxetine | Caution | SAMe has antidepressant and monoamine-modulating activity. Duloxetine increases serotonin and norepinephrine signaling, so adding SAMe may increase... |
| Escitalopram | Caution | SAMe has serotonergic properties that may potentiate escitalopram's effects. While some psychiatrists use SAMe augmentation in treatment-resistant... details → |
| Fluoxetine | Caution | SAMe increases serotonergic activity through multiple mechanisms. Combined with fluoxetine's potent and long-lasting SERT inhibition, the risk of... details → |
| Fluvoxamine | Caution | SAMe has independent serotonergic and antidepressant activity. Combined with fluvoxamine, the additive serotonergic load raises the risk of... |
| Paroxetine | Caution | SAMe has independent serotonergic and antidepressant activity. Combined with paroxetine, the additive serotonergic effect raises the risk of... |
| Sertraline | Caution | SAMe (S-adenosylmethionine) has demonstrated antidepressant properties and increases serotonergic, noradrenergic, and dopaminergic activity. When... details → |
| Trazodone | Caution | SAMe has independent serotonergic and antidepressant activity. Combined with trazodone (a serotonin reuptake inhibitor whose active metabolite mCPP... |
| Venlafaxine | Caution | SAMe has antidepressant and monoamine-modulating activity. Venlafaxine increases serotonergic signaling, especially at lower and moderate doses, and... |
| Methylcobalamin | Synergy | SAMe is the universal methyl donor; methylcobalamin supports the methionine cycle that regenerates SAMe. |
| Vitamin B6 | Synergy | Supplemental SAMe increases flux through the methionine cycle and generates homocysteine downstream. Vitamin B6 is the cofactor that allows the... details → |

What interacts with SAMe?
In the NutriStack database, SAMe has 16 documented interactions with other supplements and medications. The most notable include SSRIs/SNRIs, Tramadol, MDMA, 5-HTP, and Buspirone.
What should you not take with SAMe?
SAMe is flagged against 3 substances in the database, including SSRIs/SNRIs, Tramadol, and MDMA. Review these with a clinician before combining, especially alongside prescription medications.
What works well with SAMe?
SAMe pairs synergistically with Methylcobalamin and Vitamin B6 in the NutriStack database. Synergy still depends on dose and timing; open any pair for the detail.
Can you take SAMe with SSRIs/SNRIs?
NutriStack classifies the SAMe and SSRIs/SNRIs pairing as contraindicated: SAMe increases serotonin synthesis. Combined with SSRIs: serotonin syndrome and/or manic switch risk. 9/11 bipolar patients developed mania on SAMe. Do NOT combine without close psychiatric supervision. Risk of mania especially high in patients with bipolar disorder.
