The Importance of Third-Party Testing
Choosing a supplement that has been third-party tested is crucial for several reasons. The supplement industry is not as strictly regulated as the pharmaceutical industry, so independent testing provides a vital layer of consumer protection. When a product is tested by an organization like NSF Certified for Sport or Informed-Sport, it means the supplement has been verified for purity, potency, and the absence of banned substances. This is especially important for athletes who are subject to anti-doping regulations, but it also benefits any consumer who wants to ensure their product is clean and accurately labeled.
Key third-party testing certifications include:
- NSF Certified for Sport: Tests for over 280 banned substances and contaminants, and verifies the product contains the ingredients listed on the label.
- Informed-Sport: Certifies that every single batch of a supplement product has been tested for banned substances by the world-class sports anti-doping lab, LGC.
- ConsumerLab.com: An independent organization that tests health and nutrition products and publishes reviews to help consumers identify the best quality products.
Creatine Monohydrate: The Gold Standard
While various forms of creatine exist, creatine monohydrate remains the most extensively researched and scientifically proven form. Its effectiveness is supported by decades of research, demonstrating consistent benefits for muscle strength, power, and lean mass. Micronized creatine monohydrate is a common variation where the particles are processed to be smaller, which can improve mixability and potentially reduce gastrointestinal distress. Unless a consumer has a specific reason to choose an alternative, creatine monohydrate is the most cost-effective and reliable option.

For consumers who prioritize maximum value without sacrificing testing, Nutricost and Naked Creatine are strong contenders. Ultimately, all these choices provide a scientifically-backed path to enhancing your exercise performance safely and effectively.

How to take creatine
A consistent daily intake of creatine monohydrate is a common approach for maintaining saturated muscle creatine stores. Some individuals may choose to start with a period of higher intake for a few days to reach saturation faster, but this is not essential for achieving benefits. Consuming creatine with a meal containing carbohydrates and protein may help improve its uptake into the muscles by stimulating an insulin response. Long-term use of creatine is generally considered safe for healthy individuals and is not typically associated with a need to cycle on and off the supplement.
Potential side effects
While generally safe, some people may experience mild side effects, particularly when first starting supplementation or when consuming larger quantities. These can include an increase in body weight (attributed to water retention within the muscles), digestive discomfort such as stomach upset or diarrhea, and muscle cramps. Maintaining adequate hydration is an important consideration when using creatine to potentially help alleviate these effects.
Other forms of creatine
While creatine monohydrate is the most extensively validated form, other variations are available, such as creatine hydrochloride (HCI) and creatine ethyl ester. Some products marketed with these forms suggest advantages in solubility or absorption, but the scientific evidence supporting these claims is not as robust as the data for monohydrate. For the most dependable results, opting for tested creatine monohydrate is advisable.
Tips for selecting a brand
- Look for certifications: Prioritize products with certifications like NSF Certified for Sport or Informed-Sport, especially if you are a competitive athlete.
- Read the label: Check for pure creatine monohydrate and ensure there are no unnecessary fillers or additives.
- Check for micronized: Micronized creatine is a plus, as it improves mixability and can reduce potential stomach issues.
- Read reviews: See what other consumers are saying about taste (or lack thereof), mixability, and their experiences with the product.
The takeaway
There is no single "best" creatine powder for everyone, but focusing on tested creatine monohydrate is the most reliable approach. High-quality, tested brands like Thorne and Momentous are excellent choices for purity, while budget-friendly options like Nutricost and Naked Creatine provide great value. The key is to verify the product's testing status and choose a reputable brand that aligns with your fitness goals and budget.
