Several supplements have evidence for depression treatment, though effects are typically modest compared to evidence-based therapy and antidepressants. Best supplements for depression includes options with reasonable evidence and several with strong cautions. This guide covers what’s supported. For moderate-severe depression, evidence-based treatment is essential. Always discuss with your healthcare provider, especially before combining with antidepressants.
Supplements with evidence
Omega-3 fatty acids (EPA particularly): Multiple studies support EPA-rich supplements for depression. 1-2 g EPA daily. Often used as adjunct to antidepressants.
Vitamin D: Deficiency associated with depression. Treatment of deficiency can improve symptoms. Modest effect in non-deficient patients.
SAMe (S-adenosylmethionine): Some evidence as adjunct or monotherapy. 800-1600 mg daily. Don’t combine with antidepressants without medical guidance.
Saffron: Some studies show benefit comparable to low-dose antidepressants. 30 mg daily.
St. John’s Wort: Significant evidence for mild-moderate depression. Major drug interactions limit use.
St. John’s Wort cautions
St. John’s Wort interacts with many medications:
- SSRIs (serotonin syndrome risk)
- Birth control pills (reduces effectiveness)
- Warfarin (reduces effect)
- Many other medications via CYP enzyme induction
Discuss all medications with prescriber before considering.
Folate considerations
L-methylfolate has been studied as adjunct for treatment-resistant depression, particularly for MTHFR variant carriers. Mixed evidence. Some prescribers recommend it.
What doesn’t have strong evidence
- Most “mood support” blends
- 5-HTP (quality concerns, interaction risks)
- Tyrosine
- Most adaptogens for depression specifically
When to seek treatment
For moderate-severe depression:
- Therapy (CBT, IPT, others)
- Antidepressants when indicated
- Combination often most effective
- Don’t delay treatment relying on supplements alone
