Pros
- High dose of both NAC and glycine per serving
- Unflavored, so it's easy to mix with any drink or food
- Vegan, non-GMO, and gluten-free, suitable for various diets
- Manufactured in a certified facility, ensuring quality and purity
- Generous 62 servings per container, offering good value
Cons
- Unflavored taste may be unpleasant for some; mixing with strong-flavored beverages is recommended

Nutricost NAC + Glycine Powder combines two powerful amino acids in a single, potent formula. With 2,000mg of N-acetylcysteine (NAC) and 2,000mg of glycine per serving, this supplement is designed for those seeking robust antioxidant support, detoxification, and potential benefits for joint and skin health. It's particularly suited for individuals who are looking to boost their glutathione levels or support their body's natural defense systems.
The standout feature is the high dosage, making it a strong choice for those who need a more concentrated product. The unflavored powder is a practical choice for those who prefer to control their intake and mix it into their favorite smoothies, juices, or even recipes. However, the natural taste of NAC is often described as bitter or slightly sulfuric, so the manufacturer's recommendation to mix it with strong-flavored beverages is spot on.
In terms of quality, the product is manufactured in an NSF Certified, GMP Compliant, FDA Registered facility, which speaks to its safety and purity. The powder is vegan, non-GMO, and gluten-free, making it accessible to a wide range of dietary preferences. The packaging is simple and functional, with a resealable pouch that helps maintain freshness, though some users might find the container less convenient for scooping without spilling.
While the product delivers on its promises, potential drawbacks include the unflavored taste, which may not be palatable for everyone, and the fact that it comes in a single size. For those who are new to NAC or glycine, starting with a smaller dose might be advisable, but the 62 servings per container provide ample opportunity to adjust. Overall, this is a high-quality, effective supplement that offers great value for the price.
In conclusion, Nutricost NAC + Glycine Powder is a solid choice for health-conscious individuals looking for a potent, clean, and affordable combination supplement. It excels in providing high doses of both compounds, and the unflavored format adds versatility. While the taste may be a hurdle, it's easily overcome with proper mixing. I would recommend this to anyone seeking to enhance their antioxidant status or support overall wellness.

Buying Guide
Form: Powder vs Capsules
Glycine is available in two primary forms: powder and capsules. Powder offers flexibility in dosing and can be mixed into water, tea, or your favorite beverage. It is ideal if you prefer to control your serving size or want to combine glycine with other powders like magnesium or protein. Capsules, on the other hand, provide convenience and portability, especially for travel or for those who dislike the taste of powder.
NOW offers both a pure powder and a 1,000 mg capsule option, while Nutricost provides multiple powder options, including a blend with NAC. If you value simplicity and precise dosing, capsules from NOW are a solid choice. For those who want to mix and match, Nutricost’s powders deliver versatility.

Purity and Certification
Both brands emphasize purity, but their certifications differ slightly. NOW glycine products are Non-GMO, Soy Free, and Vegan, and are manufactured in facilities with ISO/IEC accredited in-house laboratories. Nutricost glycine powders are also Non-GMO and Gluten Free, made in GMP compliant, FDA registered facilities. Additionally, some Nutricost products carry NSF certification, an extra layer of quality assurance.
When choosing between the two, consider whether you have dietary restrictions such as gluten intolerance or if you prefer a vegan label. Both brands meet high standards, but Nutricost’s NSF certification on select products may appeal to those seeking third-party verification.

Serving Size and Convenience
Serving size matters when you plan your daily intake. NOW’s glycine powder provides a generous 1-pound container with a suggested serving that fits a typical 5-month supply if used daily. The capsule version offers 100 capsules at 1,000 mg each, making it easy to take on the go. Nutricost’s single 1-pound powder also offers a 5-month supply, and their 2-pack option extends that duration even further.
If you prefer a set-it-and-forget-it approach, capsules from NOW are convenient. For those who want the most flexibility and a longer supply, Nutricost’s 2-pack powder is worth considering. Remember that powder requires a scoop (included) and some mixing, while capsules are grab-and-go.
Brand Reputation and History
NOW has been a family-owned manufacturer of natural products since 1968, earning a loyal following for quality and transparency. Nutricost is a newer but rapidly growing brand known for offering solid supplements at accessible prices. Both have strong ratings among users, but NOW’s decades of experience may appeal to those who prioritize longevity in brand trust.
If you value a track record of consistency, NOW is a safe bet. If you prefer a modern brand with frequent product innovations, Nutricost offers a range of glycine-based options, including the NAC + Glycine blend.
