3g Balances Cortisol and Increases Deep Sleep within minutes - Dr David Sinclair

Описание: What if one simple amino acid could help you detach from stress, improve sleep architecture, and optimize cortisol rhythm?

In this 20-minute deep dive, Dr. David Sinclair explores the overlooked power of glycine — a naturally occurring amino acid with profound effects on sleep quality, autonomic balance, and metabolic health.

You’ll discover how 3 grams before bed can dramatically enhance deep sleep, why 1 gram in the morning may improve stress resilience, and the neuroscience behind glycine’s role as both an inhibitory neurotransmitter and NMDA receptor modulator.

From cortisol regulation to emotional flexibility and circadian rhythm optimization, this video reveals a strategic protocol designed to improve performance, recovery, and long-term health.

If you struggle with sleep, chronic stress, rumination, or poor recovery — this may be the simplest intervention you haven’t tried.

Watch until the end for dosing strategies, timing protocols, and the science behind why glycine works.

💡 POWERFUL VIRAL TOP 5 TIPS

1️⃣ Take 3g glycine 30–60 minutes before bed to enhance deep sleep and reduce nighttime awakenings.

2️⃣ Add 1g in the morning to improve stress resilience and emotional control during high-pressure situations.

3️⃣ Combine glycine with creatine to support brain energy stability and recovery.

4️⃣ Use glycine consistently for 2–4 weeks before evaluating results — sleep architecture adapts gradually.

5️⃣ Track sleep score, morning alertness, and stress reactivity to objectively measure impact.
