Sleep Stacks: Combining Supplements Safely
Magnesium with theanine, melatonin with glycine — 'stacking' sleep supplements is popular online. Which combinations have logic and evidence, and which combinations create real risk.
Key takeaways
- Sensible combos with evidence or strong logic: magnesium glycinate + theanine, melatonin + glycine, theanine + GABA.
- Redundant stacking wastes money — two melatonin-containing products or overlapping valerian-and-passionflower blends double sedation risk.
- Check total doses: 'PM' blends often each contain melatonin, and taking several means accidentally megadosing.
- Herb-drug interactions are the hidden danger: valerian, ashwagandha, and 5-HTP each interact with common medications.
- Add one supplement at a time, wait a week, and track effects — a stack you can't attribute effects to is a stack you can't manage.
