Optima Max Glynac
Optima Max Glynac Sale price £35.00

GlyNAC is a synergistic combination of glycine and N-acetylcysteine (NAC), two amino acids that serve as critical precursors for the body’s production of glutathione, one of the most important antioxidants for cellular health.

Glutathione plays a central role in protecting cells from oxidative stress, supporting detoxification processes, and maintaining mitochondrial function. Research indicates that glutathione levels naturally decline with age, which may impact cellular resilience, metabolic efficiency, and overall physiological balance.

Supplementing with GlyNAC provides the body with the building blocks required to support endogenous glutathione production, rather than supplying glutathione directly. This approach aligns with mechanisms studied in ageing and metabolic research, where restoring precursor availability has shown promise in supporting cellular defence systems.

NADdirect GlyNAC is formulated to deliver a consistent, standardised dose of both glycine and NAC, supporting daily intake as part of a structured, preventative wellness routine. It is designed for individuals who prioritise purity, transparency, and science-informed formulation, without unnecessary fillers or additives.

why Optima Max Glynac

Elevate your cellular vitality

Glutathione & Cellular Defence Support

A sophisticated blend of Glycine and N-Acetylcysteine, two key precursors known to support the body’s natural antioxidant defences. This advanced formulation helps optimise cellular energy processes, promote metabolic efficiency, and sustain resilience against everyday oxidative stressors. Designed for those exposed to oxidative stress, fatigue, or seeking overall cellular rejuvenation. GlyNAC is your foundation for enduring vitality at the cellular level.

Recommended Dosage

Take 2 capsules per day with water before a meal. This equals to 600mg of NAC and 600mg of Glysine. 

⚠️ Do not exceed the recommended daily intake.

Who is it for?

✔ Individuals looking to support cellular antioxidant defences
✔ Those seeking to maintain healthy glutathione levels with age
✔ People focused on mitochondrial health and metabolic support
✔ Individuals exposed to high physical, cognitive, or environmental stress
✔ Those following science-led, preventative longevity approaches
✔ Individuals combining NAD+, fasting, or metabolic optimisation protocols

Combined with NAD+  

GlyNAC and NAD+ support distinct but complementary cellular systems:

  • GlyNAC supports glutathione production and cellular defence against oxidative stress
  • NAD+ plays a central role in cellular energy metabolism and DNA repair

Together, they are often used in longevity-focused routines to support both cellular energy production and cellular protection, helping maintain balance between metabolic output and antioxidant capacity as part of a comprehensive, mechanism-based approach to healthy ageing.

Benefits
  • Boosts Glutathione and antioxidant defence
  • Improves mitochondrial function
  • Enhances energy, immunity, and metabolic health
  • Promotes healthy aging
Combine it with other products

For advanced cellular defence and longevity support, combine GlyNAC with Optima Max Spermidine and the NAD+ Smart Pen. GlyNAC supports glutathione production and cellular protection against oxidative stress, Spermidine activates autophagy and cellular renewal, and NAD+ drives cellular energy metabolism and DNA repair. Together, they form a comprehensive, mechanism-based approach to cellular resilience and healthy ageing.

FAQs

Find quick answers to the most common questions about our products.

Why not just take glutathione directly?

The body regulates glutathione production per cell individually. Too little or too much can be harmful. Direct glutathione supplementation bypasses this regulation. GlyNAC provides the building blocks and lets each cell synthesise exactly what it needs.

What clinical evidence supports GlyNAC?

Dr Rajagopal Sekhar at Baylor College of Medicine has conducted multiple clinical trials demonstrating that GlyNAC supplementation in older adults significantly improved glutathione deficiency, oxidative stress, mitochondrial function, inflammation, cognition, strength, and gait speed. A randomised controlled trial published in 2022 replicated and extended these findings.

What is the role of NAC?

N-Acetylcysteine provides cysteine, the rate-limiting amino acid in glutathione synthesis. NAC is also a direct antioxidant and supports respiratory and liver health.

Can it be combined with NAD+?

Yes. GlyNAC and NAD+ support distinct but complementary cellular systems. NAD+ targets energy metabolism and GlyNAC targets antioxidant defence. They are frequently combined in comprehensive longevity stacks.

What are the contraindications for this product?

As with all food supplements, certain individuals should exercise caution. This includes people who are pregnant or breastfeeding, those with pre-existing medical conditions, individuals currently taking prescription medication (including blood thinners, diabetes medication, immunosuppressants, or thyroid medication), and those under the age of 18. Supplements are not intended to diagnose, treat, cure, or prevent any disease. We strongly recommend that every client consults a qualified healthcare professional before starting any new supplement, particularly if they have an existing health condition or are taking medication. When in doubt, escalate to the NADclinic clinical team.
