Best Supplements for Stress
3 evidence-based options for stress, summarized from the research: what they do, how to dose them, and how they work together.
Ashwagandha
An adaptogenic herb for stress and resilience.
L-Theanine
Calm, focused alertness from green tea.
Magnesium
A master mineral involved in 300+ enzyme reactions.
Combinations to know
How these supplements pair with each other and beyond.
Ashwagandha + L-Theanine
Both promote calm; frequently stacked for stress management.
Ashwagandha + Magnesium
Commonly combined for stress relief and better sleep quality.
L-Theanine + Magnesium
Both calm the nervous system, a popular combination for relaxation and sleep.
Caffeine + L-Theanine
The classic nootropic stack: L-theanine smooths caffeine's jitters while preserving the focus boost.
Magnesium + Vitamin D3
Magnesium is required to convert vitamin D into its active form, so low magnesium blunts D3's benefits.
Calcium + Magnesium
Compete for absorption at very high single doses; keep intake balanced rather than mega-dosing one.
