Frequently Asked Questions
1. What is GlyNAC?
GlyNAC is a precision combination of two amino acids — Glycine and N-Acetylcysteine (NAC) — that together act as the direct precursors to glutathione, the body’s most important endogenous antioxidant. Glutathione production naturally declines with age, contributing to oxidative stress, mitochondrial dysfunction and many of the visible signs of biological ageing.
Optima Max GlyNAC delivers a clinically meaningful 600mg of each precursor per serving. Multiple randomised controlled trials at Baylor College of Medicine have shown that GlyNAC supplementation can support glutathione restoration and address multiple hallmarks of ageing — making it one of the most evidence-backed additions to a longevity-focused routine.

2. Who is it for?
GlyNAC is suited to:
- Individuals looking to support glutathione production and antioxidant defence.
- Those seeking to support mitochondrial function and cellular resilience.
- People interested in addressing oxidative stress and inflammaging.
- Anyone following a science-led longevity or healthy ageing protocol.
- Those complementing NAD+, fasting or metabolic optimisation regimens.
3. Can I take it with other supplements?
Yes — GlyNAC is one of the most foundational supplements in a longevity routine and pairs particularly well with other cellular renewal and NAD+ actives.
Pairs particularly well with:
Pairs particularly well with:
- Ca-AKG — supports the Krebs cycle, epigenome and mitochondrial efficiency, complementing GlyNAC’s role in antioxidant defence and cellular resilience.
- Spermidine — supports autophagy and cellular renewal, working alongside GlyNAC to address multiple hallmarks of ageing.
- Enhanced Optima Max (NAD+) and Neuro Optimiser (NR) — together with GlyNAC, these form the textbook longevity stack: glutathione restoration plus direct NAD+ support for cellular energy.
- Omega-3 PRO — foundational anti-inflammatory support that reinforces GlyNAC’s antioxidant benefits.
4. How does it combine with NAD+?
GlyNAC and NAD+ support different but complementary cellular pathways — GlyNAC supports glutathione synthesis and antioxidant defence, while NAD+ supports cellular energy and metabolic function.
Because glutathione restoration is fundamental to skin health, oxidative stress and the visible signs of ageing, GlyNAC also pairs beautifully with our topical Active NAD+ Face Serum and Active NAD+ Essential Cream — addressing antioxidant defence from within while supporting skin renewal at the surface.

5. When will I see results?
GlyNAC’s benefits are associated with long-term cellular processes including glutathione restoration and mitochondrial support. Consistent daily use is recommended for best results.
