Unit Size: 70ct

A multi-functional nootropic formula that benefits for cognitive health, enhanced focus, musculoskeletal support and vision defense.

N-acetyl cysteine ethyl ester (NACET) is a supplement form of the amino acid cysteine with a greater bioavailability than N-acetyl cysteine (NAC). NACET is a potent scavenger of harmful free radicals.

Glycine is the supplement form of a nonessential amino acid that acts as a precursor to several important metabolites in the body and is not generally sufficiently synthesized in humans under normal dietary conditions.


[Nacet X Glycine Capsules] Benefits and Uses

Our easy-to-take NACET and glycine capsules (GlyNAC-ET) provide a more stable version of NACET that helps to reduce reflux and may be taken for a range of health benefits:

Joint Support and Anti-Aging:

Research suggests that a combination of N-acetyl cysteine ethyl ester (NACET) and glycine help to support overall health and promote healthy aging by countering glutathione deficiency. Glutathione, which depletes with age, is a critical cellular defense system against many forms of stress, and is a powerful antioxidant for musculoskeletal and immune health.

Focus and Cognitive Clarity:

Recent studies have found that a combination of N-acetyl cysteine ethyl ester (NACET) and glycine may support brain health, reducing cognitive decline in aging adults, as well as notably improving cognition in healthy adults.

Vision Support:

A high-tier nootropic, NACET X Glycine capsules may help to sharpen and preserve vision and ocular health.

[NACET X Glycine] is known by a number of alternative names, including:

  • GlyNAC-ET
  • Glycine + N-acetyl cysteine ethyl ester
  • GlyNAC
  • GlyNACET

Scientific Consensus

Scientific research continues to explore the benefits of NACET and Glycine supplementation. GlyNAC-ET is considered safe for use when taken at the recommended serving size. NACET X Glycine (GlyNAC-ET) may cause side effects including nausea, diarrhea, and constipation. Please contact your physician if you are taking any medication or have/suspect any underlying medical conditions. Safety has not been established for pregnant or breastfeeding women.

Quality supplement manufacturing: Due to the heat sensitivity of NACET, LiftMode implements special in-house control procedures to ensure our NACET X Glycine (GlyNAC-ET) capsule ingredients are consistently kept at sub-zero temperatures whenever stored or handled.

NACET (N-Acetyl L-Cysteine Ethyl Ester)

NACET is an N-Acetyl L-Cysteine amino acid (pictured to the left) with an added ethyl ester group. Studies have indicated that the additional ester group enhances cellular uptake and bioavailability. NACET is best-known for its ability to improve intracellular glutathione levels. In effect, NACET has fascinating antioxidant properties to help support healthy ageing. Studies have indicated that NACET’s antioxidant effects are also potent in the eyes, where it protects retinal cells against oxidative damage. - Enhanced bioavailability form of N-Acetyl L-Cysteine (NAC) - Improves intracellular glutathione levels, powerful antioxidant - Protects retinal cells against damage and supports healthy ageing



Glycine is a naturally occurring precursor amino acid to glutathione. It can be found in naturally occurring sources of protein such as meat, dairy, and legumes. It is a powerful scavenging antioxidant that helps to reduce oxidative stress inside cells, and may help to reduce age-related glutathione deficiency. Glycine supplementation has been found to increase tissue glutathione levels in some studies, while also supporting connective tissue and joint health. Other research has indicated that glycine may improve mood and sleep quality, by increasing extracellular serotonin. - Boosts glutathione levels - Supports healthy joints - Reduces oxidative stress - Boosts mood and sleep quality.
