GlyNAC works by combining glycine and N-acetylcysteine (NAC) to support your body’s production of glutathione, one of the most important antioxidants in the human body. Together, these two amino acids act synergistically to improve cellular health, mitochondrial function, and oxidative balance, all of which are central to healthy aging and overall vitality.
Is GlyNAC safe?Yes, GlyNAC is generally considered safe when taken at appropriate doses and under the guidance of a healthcare provider, especially for healthy adults. Glycine is a naturally occurring amino acid found in protein-rich foods and is typically well tolerated, even at higher doses (up to 3–5 grams/day in studies). N-Acetylcysteine (NAC) is also widely used and has a long safety history in both clinical and over-the-counter applications, including as a mucolytic agent and antioxidant. Typical supplement doses range from 600–1800 mg/day.
A notable study showed that GlyNAC was safe and well-tolerated over 24 weeks in older adults. The study reported no significant adverse effects and showed improvements in mitochondrial function, oxidative stress, insulin resistance, and physical performance.

Mix 1 scoop (approx. 5g) with 200-300ml of water, once or twice daily. Best taken on an empty stomach for maximum absorption.

GlyNAC supplementation has been shown in clinical studies to reverse multiple hallmarks of aging in older adults—including improved mitochondrial function, reduced oxidative stress, enhanced insulin sensitivity, and even increased walking speed—in as little as 12 weeks.
This makes GlyNAC one of the few compounds with human evidence supporting its ability to target the biology of aging at a cellular level.
