10 episodes · 29 references · 2021–2025
- Stanfield takes glycine himself (~3,200 mg nightly) based on consistent sleep evidence and mouse lifespan data showing 4–6% extension - Strong enthusiasm for glycine's sleep, glutathione, and longevity benefits, supported by multiple RCTs and the Interventions Testing Program - No cautions, warnings, or reasons to avoid discussed in any reference
Consumption
- Stanfield takes just over 3,200 mg of glycine daily as part of his sleep supplement - Started taking it after being convinced by repeated sleep improvement findings across studies - No specific brand or standalone form mentioned; included in a combined sleep supplement
Benefits
- Improves sleep onset and deep sleep by lowering core body temperature via vasodilation, without disrupting sleep architecture - Mouse lifespan extended 4–6% across three independent ITP testing sites; also activates autophagy - Building block for glutathione (with NAC), reducing oxidative stress and supporting mitochondrial function in aging
Best Practices
- Standard dose is 3 grams per day, the amount used in most sleep studies - Take shortly before bedtime for sleep benefits - Generally considered safe at typical doses of 1.5–3 grams per day per recent review recommendations
