Buying Guide: What to Look for in a Creatine Supplement
Form: Capsules vs. Powder
The first decision is convenience versus flexibility. Capsules are pre-measured and easy to swallow. You can toss a bottle in your gym bag and take them without mixing. Optimum Nutrition’s capsules provide 2.5 grams per two-capsule serving. If you dislike the taste of creatine powder or want a grab-and-go option, capsules are ideal.
Powder, on the other hand, lets you adjust your serving size and mix it into shakes, water, or juice. The unflavored powder blends seamlessly into any beverage. For those who already use a protein shake post-workout, adding a scoop of creatine powder is effortless. Our optimum nutrition amino energy review shows how stacking supplements can enhance your pre-workout routine.
Micronization and Mixability
Micronized creatine has been processed into smaller particles. This improves its ability to dissolve in liquid, reducing grittiness and settling. Optimum Nutrition uses micronized creatine monohydrate in both its capsules and powder. With powder, you will notice it mixes quickly with minimal clumping. Capsules bypass mixing entirely, so micronization ensures rapid absorption once digested.
If you have ever struggled with gritty creatine powders, micronized versions are a game changer. The fine texture makes it easy to down without a chalky aftertaste. For a closer look at how Optimum Nutrition’s other powders perform, see our optimum nutrition platinum hydrowhey review.
Purity and Quality Assurance
Not all creatine supplements are created equal. Some contain fillers, artificial additives, or lower-grade raw materials. Optimum Nutrition prides itself on purity. Their creatine is sourced from premium ingredients and undergoes third-party verification through the Informed Choice program. This means every batch is scanned for banned substances, giving you peace of mind.
For athletes subject to drug screening, this level of quality assurance is non-negotiable. It also reflects the brand’s commitment to transparency. You can view certificates of analysis on their website. If you value rigorous quality control, Optimum Nutrition’s entire line meets high standards. Our optimum nutrition gold standard casein review highlights similar dedication to purity in their slow-digesting protein.
Serving Size and Value
Consider how many servings you need per month. A standard creatine dose is 5 grams daily. The 100-count capsules provide 50 servings (2 capsules each), while the 300-count offers 150 servings. The 60-serving powder tub gives you 60 servings, and the 120-serving tub delivers 120 servings. Think about your usage frequency and storage space. Capsules take up less room but cost more per serving. Powder offers better value for long-term use.
If you are just starting out, the smaller capsule bottle is a low-commitment way to try creatine. For seasoned users, the larger powder tub reduces per-serving cost and reduces packaging waste.

Final Thoughts
Both forms of Optimum Nutrition micronized creatine deliver the same high-quality monohydrate. If you prioritize convenience and portability, the Optimum Nutrition Micronized Creatine Monohydrate capsules are your best bet for on-the-go supplementation. If you want maximum value and flexibility to mix into your favorite drinks, the Optimum Nutrition Creatine Monohydrate Powder in the 120-serving tub is the smarter long-term choice. Whichever you pick, you are getting a verified, pure creatine that supports strength, power, and recovery.
Frequently Asked Questions
How much creatine should I take per day?
The standard dose is 5 grams daily. Some people use a loading phase of 20 grams for five to seven days, but this is optional. Optimum Nutrition’s capsules make it easy to start with 2.5 grams per serving if you prefer a lower dose. As of 2026, most research supports 3 to 5 grams per day for ongoing maintenance.
Can I take creatine with protein powder?
Yes, combining creatine with protein is a common and effective stack. Mixing unflavored creatine powder into a shake is seamless. For best results, consume creatine post-workout alongside protein to support muscle recovery. You can learn more about protein timing in our optimum nutrition gold standard casein review.
Is micronized creatine better than regular creatine?
Micronized creatine has smaller particles, which means it dissolves more easily in liquid and may be absorbed faster. It reduces the grittiness often associated with standard creatine powders. Both forms are equally effective, but micronized offers a better user experience, especially for those sensitive to texture.
How long does it take for creatine to work?
Creatine saturates your muscles over time. With a loading phase, you may notice increased strength and power within the first week. Without loading, it typically takes two to four weeks to reach full saturation. Consistency is key.
