Why buy

The level of glutathione – a key antioxidant in the body – naturally decreases with age. The GlyNAC complex from Purovitalis provides exactly the substances the body needs for its own restoration.

Each capsule contains 300 mg of L-glycine and 300 mg of N-acetylcysteine – a dose corresponding to clinical research. This combination creates a synergy that can be more effective than NAC alone.

The raw materials used meet pharmaceutical standards and contain no fillers or binders. Manufacturing takes place in the EU in a GMP certified facility and each batch is tested in an independent laboratory.

The supplement is intended for those who care about their cellular health, long-term vitality, and metabolic balance.

Who is GlyNAC Clarity suitable for

• Adults in middle and older age (35+) who want to support glutathione production and vitality.
• Active athletes seeking faster recovery and protection against oxidative stress.
• People with increased mental or physical stress – for example, during stress, demanding work, or frequent travel.
• Individuals interested in biohacking and longevity and wanting to support mitochondrial functions.
• Anyone striving for mental freshness and energy in daily life.

When is the product not suitable

• For children, pregnant and breastfeeding women.
• In case of serious liver or kidney diseases – we recommend consulting a doctor.
• When taking blood-thinning medications or chronic diseases, it is advisable to consult a specialist.

Key benefits

• Glycine and NAC – two amino acids needed for the production of glutathione.
• 300 mg of each component per capsule – a dose corresponding to clinical studies.
• High purity of raw materials – only L-glycine and N-acetylcysteine of pharmaceutical quality.
• Without fillers, binders, and synthetic additives – nothing extra, just the essentials.
• Manufactured in the EU + GMP certification – laboratory tested, with an emphasis on safety.
• Effective synergistic formulation – glycine and NAC work better together than separately.
• Composition based on available studies – designed based on real research.
• Focused on balance – in the body, stable energy, and everyday vitality.

Composition

L-glycine, N-acetylcysteine, microcrystalline cellulose, hydroxypropylmethylcellulose (vegan capsule).

Dosage

Take 2 capsules in the morning with food.

How to take

NAC is traditionally recommended to be taken on an empty stomach because food (especially proteins) can partially reduce its absorption. On the other hand, in more sensitive people, it can cause mild digestive issues (heartburn, nausea).

Glycine is an amino acid that is well tolerated even with food and is sometimes taken in the evening to support sleep.

In the GlyNAC combination (300 + 300 mg in one capsule), it is most often administered with food in clinical studies because:

• it reduces the risk of stomach irritation,
• a regular daily routine makes adherence easier,
• good bioavailability was confirmed in practice even when taken with food.

Practical recommendations

• The safest and most convenient is to take with food (e.g., with breakfast or lunch).
• With a sensitive stomach, food is a necessity.
• If the goal is to maximize NAC absorption, it can be taken 30–60 minutes before a meal, but this option is more suitable for experienced users or after consulting a specialist.

How to combine GlyNAC with other supplements

Warning: This is a dietary supplement. It does not replace a varied and balanced diet or a healthy lifestyle. Not suitable for children, pregnant and breastfeeding women. Consult a specialist when taking medication.

How GlyNAC works

With increasing age, the level of glutathione in the body decreases – a substance that naturally participates in protecting cells from oxidative stress. This imbalance can be associated with higher mitochondrial load, decreased energy, and disruption of the natural balance inside cells.

This complex combines L-glycine and N-acetylcysteine, two amino acids that the body uses as direct precursors of glutathione. Their regular intake can help the body restore its natural antioxidant capacity and maintain proper cell function.

The result can be better energy metabolism, more stable mental performance, higher resilience to stress, and support for overall cellular balance. These effects have been observed in several published clinical studies.

Studies and research

• Restoration of glutathione and reduction of oxidative load – A 24-week clinical study monitored the effect of GlyNAC in older adults. Results showed a significant increase in glutathione levels and a reduction in oxidative stress markers.

  🔗 STUDY

• Impact on mitochondria and cellular energy production – Research published in Frontiers in Aging focused on mitochondrial balance. Supplementation with GlyNAC was associated with improved cellular energy efficiency.
  🔗 STUDY

• Observed impact on memory, walking, and muscle strength – A controlled study recorded improvements in selected physical and cognitive functions – including walking speed, memory, and muscle performance.
  🔗 STUDY

• Changes in inflammatory markers and insulin sensitivity – Further research showed reduction in levels of substances associated with inflammatory response and improvement in insulin sensitivity, which are linked to metabolic balance.
  🔗 STUDY

• Due to legal regulations, we cannot make more specific statements about the effects of some ingredients in dietary supplements. This is why there is very little or no information about the effects of some products. Additionally, if no effect is mentioned, you can conduct your own research and form your own opinion about the products. We ask for your understanding in this regard.

FAQ

How long does it take for the product to work?

Clinical studies suggest that visible benefits may appear in approximately 8–12 weeks with regular daily use.

When to take it during the day?

It is recommended to take 2 capsules in the morning with food to align with the body's natural rhythms and support energy throughout the day.

Is GlyNAC complex better than NAC alone?

Yes. The combination of glycine and NAC has been shown to more effectively increase glutathione and support proper mitochondrial function than NAC alone.

Why take GlyNAC complex instead of glutathione?

GlyNAC provides precursors needed for the internal synthesis of glutathione, which can be more effective than direct glutathione due to its limited absorption.
