Buying Guide
What to look for when choosing glycine-and-GABA sleep aids:
- Glycine dose: Most products list 3000 mg per serving. Confirm serving size and whether you need 1 or 2 gummies per dose.
- GABA and L-Theanine: These are common calming ingredients that help reduce brain activity before bed. Check their presence and relative amounts.
- NAC and magnesium: NAC supports antioxidant balance; magnesium (glycinate preferred) aids muscle relaxation. Consider your tolerance for NAC or magnesium-based products if you have digestive sensitivity.
- Vegan, sugar-free, and allergen considerations: Many options are vegan and sugar-free, which helps with daily dietary goals.
- Melatonin-free: If you prefer no melatonin, verify ingredients to avoid melatonin blends.
- On-the-go or night-time routine: Gummies are convenient, but powder forms or capsules may suit different lifestyles.
