Doctor Developed: Formulated by a medical doctor, for himself and his family, using ingredients informed by human research — not because they’re trending. So you get the same carefully considered formula he chooses for the people closest to him.

Meaningful Doses: 1,000 mg of Glycine plus 500 mg of N-Acetyl L-Cysteine (NAC) in every daily serving. No proprietary blends. No hidden doses.

Built To Work Together: Glycine and NAC provide two of the key building blocks your body uses to make glutathione — one of the body’s most important natural antioxidants.

Tested for Trust: Every batch is independently third-party tested for dose, purity and contaminants.

Active Ingredients

Each daily serving of 2 capsules contains:

Glycine — 1,000 mg

An amino acid your body uses for a wide range of functions, including the production of glutathione. Glycine has also been studied for its role in supporting sleep quality.

N-Acetyl L-Cysteine (NAC) — 500 mg

A stable form of cysteine. NAC provides cysteine that the body can use to produce glutathione, helping support its natural antioxidant defenses.

Designed To Work Together

Glutathione is often described as the body’s “master antioxidant” because of its important role in protecting cells from oxidative stress.

But glutathione is a relatively large molecule made from three amino acids, and its absorption when taken directly can be limited and variable.

Instead, Glycine + NAC provides two of the key building blocks your body uses to make its own glutathione. Glycine provides glycine directly, while NAC provides a source of cysteine.

This combination has been shown in human studies to effectively increase glutathione levels, supporting the body’s own antioxidant defenses.

Allergies

Free from gluten, dairy, soy, artificial colors, preservatives and artificial flavoring.

Research-Led Formulation

Rather than relying on supplemental glutathione itself, our formula provides glycine and NAC — two of the building blocks your body naturally uses to produce glutathione.

Human studies of Gly NAC have shown that supplementing with glycine and NAC can increase glutathione levels and support antioxidant defenses.

Each daily serving provides 1,000 mg of Glycine alongside 500 mg of NAC.

Third-Party Tested

Every batch is independently tested for dose, purity and contaminants including heavy metals and microbes.

Manufactured in the USA in a GMP-certified, FDA-registered facility under strict quality standards.

Directions

Take 2 capsules daily with food (consider taking them in the evening with or just after your last meal).

Why take it in the evening? You can take Glycine + NAC with any meal, but we suggest taking it with or after dinner. Glycine has been studied for its role in supporting sleep quality, making the evening a natural time to take it.

There’s no need to take it at an exact time. Choose a routine that works for you and take it consistently each day.

Each serving provides 1,000 mg of Glycine and 500 mg of NAC.

Glutathione is one of the body’s most important natural antioxidants, helping protect cells against oxidative stress. Glycine and NAC provide two of the building blocks your body needs to produce it.

Chronic inflammation is recognized as one of the 12 hallmarks of aging.

Support glutathione production: Glycine and NAC provide two of the three amino acids your body uses to make glutathione, supporting your natural antioxidant defenses.

Support cellular protection: By supporting glutathione production, Glycine + NAC helps support the body’s defenses against oxidative stress and healthy cellular function.

Support better sleep: Glycine has also been studied for its role in supporting sleep quality, making Glycine + NAC a natural fit for an evening routine.
