Evidence-based supplements and habits for mood stability, anxiety reduction, and emotional wellbeing.

What to expect

Synthesized from research on this protocol's components. Individual response varies.

Weeks 4–8

Look for: Depressive symptoms may begin to ease — omega-3 PUFA supplementation shows a beneficial effect on depressive symptoms in adults with major depressive disorder, with a typical magnitude of about 2.2 points on the 17-item Hamilton Depression Rating Scale, and effects are stronger when combined with prescribed antidepressants.

Not yet expected: Strong mood lift from vitamin D supplementation alone — meta-analyses of randomized trials find no significant effect on depression scores, and pure DHA supplementation does not significantly reduce depressive symptoms.
