10 Best Creatine Supplements of 2026, Tested by Us

Thorne Creatine provides 5 grams of easily mixable micronized creatine monohydrate and nothing else. It’s NSF Certified for Sport and cost-effective at under 50 cents per serving, making it an excellent choice for nearly anyone looking to put on muscle. This is one of the brands most commonly used by athletes and is officially partnered with the UFC Performance Institute, being used by a lot of MMA fighters.

This powder has been my creatine supplement of choice for nearly two years, and I’ve been impressed with how it performs. It mixes easily, is truly tasteless, and doesn’t have any of that gritty texture creatine powders can sometimes have. If you’re new to performance supplements, Thorne’s products are a reliable starting point, designed with a focus on minimal, clean, and transparent ingredients backed by clinical research for safety and efficacy.

This creatine from CytoSport, parent company of Muscle Milk, is the new iteration of Muscle Milk’s Pro Series Creatine. The sleek, newly designed packaging is nice, but what we love most is that this version maintains its reputation with a familiar and NSF-certified formula. Each serving delivers a solid 5 grams of creatine monohydrate, making it a consistent choice for those seeking muscle-building benefits.

Beyond its no-frills formulation, a whopping 100 servings per container adds the perks of convenience and cost-efficiency. This means it’ll last at least three months for a single user. It’s also the cheapest creatine that has satisfied our testing criteria over the years.

Plus, we love the easily stackable, mess-free tub packaging. The cap is well-designed to keep the powder fresh and prevent the frustrating scenario of spillage.

If avoiding GMOs is important to you when it comes to your food, there’s no good reason your supplements should be the exception. This Non-GMO Project– verified offering is made from Creapure, known as a high-purity micronized creatine produced in Germany (which is why it says “German Creatine” on the container). The serving of the standard 5-gram dose dissolves effortlessly in every liquid we tested, with no clumping issues that can plague other powders.

In terms of purity and quality, Sport Research has secured an Informed Sport certification, meaning what’s on the label is precisely what you’re getting in each serving. For individuals seeking a creatine supplement to accommodate their preferences and take out the guesswork out of dosing, this option is worth exploring.

Gnarly’s Creapure unflavored creatine delivers 5 grams per serving, contains no additional ingredients, and is NSF Certified for Sport. Creapure is a patent-protected, micronized creatine monohydrate known for its rigorous research, focusing on purity and safety. While the research comparing it to other certified forms of creatine monohydrate is inconclusive, products featuring Creapure often come with a higher price tag.

Despite its higher price, I conducted my own test after three months creatine-free, taking this powder twice daily for the first two weeks as recommended by the brand. Within that timeframe, I observed a roughly 10-20% increase in the reps of exercises like burpees, squat jumps, and overhead presses during AMRAP workouts.

This NSF for Sport certified option from Klean Athlete delivers 5 grams of pure creatine monohydrate per scoop without any artificial flavors or added ingredients. While it offers a modest 60 servings, it’s a great pick if you’re seeking a creatine supplement for short-term use or to leave at the gym or office.

You can enjoy free delivery regardless of your order’s total amount, but while you’re at it, you can also try out other Klean Athlete products. We love the Klean Isolate whey protein powder as a standalone addition or the Muscle Building Bundle, which includes the protein powder, creatine, and two additional products to support your gains.
