Glycine is often promoted as a simple anti-ageing supplement — but does it actually live up to the hype?

In this episode, I break down what glycine really does in the body and whether the claims around anti-ageing, longevity, sleep quality, collagen production, and metabolic health are supported by science or taken out of context.

We explore glycine’s role as a conditionally essential amino acid, how it interacts with the nervous system, why it’s commonly used before sleep, and where the evidence is strong — and where it’s overstated.

Rather than selling you another “hack,” this episode focuses on critical thinking in nutrition, helping you understand when glycine may be useful, who might benefit most, and why supplements should complement — not replace — good lifestyle foundations.

In this episode, we cover:

• What glycine is and why it’s important
• Glycine and sleep: mechanisms and real benefits
• Collagen, connective tissue, and ageing claims
• Longevity research: what we know vs what’s exaggerated
• Dosage, timing, and practical considerations
• How to think critically about supplement trends

This episode is for anyone interested in evidence-based nutrition, longevity, and making smarter supplement choices.
