Creatine is one of the most researched and effective sports supplements available, with numerous studies confirming its benefits for strength and muscle growth. GNC offers a wide array of options, but whether their house brand and other selections are truly high-quality depends on your specific fitness needs and budget.

Quick Summary

GNC's creatine, particularly its Pro Performance Monohydrate, offers a budget-friendly, pure, and effective option for many users. The company also stocks a variety of third-party tested, advanced creatine formulas from other brands. Quality is generally reliable, but consumer preference may vary based on factors like mixability and cost.

Key Points

In-House Quality: GNC's Pro Performance Creatine Monohydrate is a reliable, budget-friendly option, produced in cGMP facilities and tested for banned substances.
Product Variety: GNC offers various creatine forms, including monohydrate and creatine HCl, both from its own brands and numerous third-party manufacturers.
Third-Party Testing: While GNC performs its own banned substance tests, many consumers prefer products with additional independent certifications like Informed-Choice or NSF, which are also available at GNC.
Mixability Issues: Some customers report that GNC's monohydrate product can be gritty and difficult to mix, while creatine HCl and micronized versions generally dissolve better.
Value Proposition: GNC creatine offers strong value, especially for beginners, but more advanced users or those with higher budgets may opt for different formulas or brands for specific features.
Creatine HCl vs. Monohydrate: Creatine monohydrate is the most extensively studied and scientifically-backed form, while HCl is marketed for superior solubility and bioavailability at a higher cost.

GNC's In-House Creatine Offerings

GNC offers its own branded creatine, primarily the Pro Performance Creatine Monohydrate. This product is manufactured in cGMP certified facilities and is tested for banned substances. It is often seen as a cost-effective starting point for those new to creatine supplementation. Another in-house option is GNC AMP Creatine HCl 189, which uses creatine hydrochloride, marketed for potentially better solubility and absorption compared to monohydrate, though monohydrate has more scientific backing.

Third-Party Brands Available at GNC

Beyond its own brands, GNC provides access to many reputable third-party creatine brands like Optimum Nutrition, NutraBio, and Kaged. These brands often feature patented forms of creatine monohydrate like Creapure®, third-party certifications such as Informed-Choice or NSF, and offer various formats like capsules, gummies, and pre-mixed blends.

Assessing Quality: The Importance of Micronization and Purity

High-quality creatine monohydrate is typically micronized for better solubility, reducing grittiness. While GNC's Pro Performance is micronized, customer feedback on its mixability is varied. Purity is also crucial, with some brands emphasizing high purity levels.

The Takeaway: GNC Creatine vs. Other Top Brands

Choosing between GNC's in-house creatine and other brands depends on individual preferences and priorities. GNC's Pro Performance is a straightforward, budget-friendly option. Creatine HCl options, available from GNC and others, may offer better mixability but are typically more expensive and less studied than monohydrate. Third-party monohydrates, while potentially pricier, can offer additional third-party certifications for those who prioritize them.
