Ashwagandha is the most-studied cortisol-lowering supplement. Here's what the meta-analyses actually show, plus dose and timing.

Frequently asked questions

Which foods lower cortisol the most? +
Strongest evidence: dark chocolate (70%+ cacao, 40g), omega-3 rich fish (salmon, sardines, 2× weekly), and magnesium-rich foods (leafy greens, pumpkin seeds, almonds). Fermented foods and polyphenol-rich items (berries, green tea, olive oil) have moderate evidence.
What foods raise cortisol? +
Reliable cortisol-raisers: excess caffeine (especially on an empty stomach), alcohol, high-glycemic refined carbs on an empty stomach, ultra-processed foods, and skipping meals when chronically stressed. The single biggest hidden cortisol input in most diets is alcohol.
Does food matter more than supplements for cortisol? +
Generally yes — food is the foundation, supplements are the layer. Fixing chronic caffeine + alcohol + nutrient deficiencies usually does more than any single supplement. But the high-evidence supplements (ashwagandha, magnesium glycinate) work synergistically with a clean foundation, not as a substitute.
