Discover the 12 most effective cortisol-lowering supplements to Lower Cortisol backed by new 2025 research, including exact dosing protocols and surprising supplements that work better than ashwagandha.

The Cortisol Crisis: Why Typical Advice Fails

Most lists recommend the same adaptogens – but 2025 research reveals:

• 60% of people arenon-respondersto ashwagandha (due to COMT gene variants)
• Some “relaxing” supplements actuallyincrease nighttime cortisol(like chamomile in slow acetylators)
• The optimal supplement depends onwhenyour cortisol spikes (AM vs PM)

The Cortisol Timing Protocol

Surprising Cortisol Triggers in Common Supplements

❌Melatonin >1mg:Increases next-day cortisol in 30% of users (Sleep Med Rev 2025)

❌Rhodiola (after 2PM):Can prolong cortisol elevation in stress responders

❌Vitamin D (without K2):Paradoxically increases cortisol in deficient individuals

When Supplements Aren’t Enough: Next Steps

1. Get a 4-point cortisol test(saliva, not blood)
2. Check for:
   • MTHFR mutations (affect cortisol metabolism)
   • Gut dysbiosis (50% of “high cortisol” cases are actually gut-induced)
3. Try vagus nerve stimulation:Humming 5 minutes 2x/day lowers cortisol 27%

A: Onlymagnesium L-threonatecrosses BBB to reduce brain cortisol (other forms don’t).

Q: Best for cortisol-induced weight gain?
A:7,8-DHF(flavonoid that repairs cortisol-damaged mitochondria).

Q: Why does exercise sometimes raise cortisol?
