Creatine is a dietary supplement that many pro-athletes and bodybuilders swear by. If you are interested in enhancing your muscle strength, size and power, and taking your performance to the next level, you should definitely give this supplement a try.

The nutritional sports industry is filled with all kinds of supplements, with carbohydrates and/or protein-rich supplements being widely used. These two nutrients work to fuel your workouts and build muscles. What you probably don’t know is that there is a third source which is just as effective as carbs and proteins – creatine monohydrate.

When you purchase creatine supplements, the first thought that crosses your mind is a smart blend to maximize creatine’s potential. The question on many people’s lips is, “can creatine be effective on its own?” The simple answer is YES, it can. Keep reading to understand how. Creatine is produced in the body naturally via the synthesis of specific amino acids. When consumed as a dietary supplement, it’s converted to Creatine Phosphate. Creatine Phosphate then helps the body in synthesizing Adenosine Triphosphate (ATP) that produces the energy that allows the muscles to contract.

If you are in search of an effective creatine supplement, you’ll be glad to know that monohydrate boasts the most scientific backing. Studies have proven that when mixed with high-intensity activities like powerlifting, CrossFit or bodybuilding, creatine supports muscle strength, power and size. There are many creatine supplements in the market which makes the job of finding the best supplement challenging.

The popularity of creatine has prompted many manufacturers to produce their versions of creatine supplement on the already crowded market. With 30+ years experience in the industry, Optimum Nutrition is a reputable brand best known for manufacturing premium-quality and award-winning sports nutrition products for athletes of all types. The company decided to join the bandwagon and produce their own version of creatine. This OPTIMUM NUTRITION Micronized Creatine Monohydrate Powder Review will help you determine whether it’s the right supplement for your weight training.


When shopping for a nutritional supplement, quality matters. The supplement industry is rife with fraud. ON creatine powder achieves a higher level of purity to guarantee you effectiveness. ON’s micronized creatine keeps the molecular structure of other creatine forms, but its particles are 20X smaller to increase the rate of absorption. Just like other products from Optimum Nutrition line, this supplement is made in a cGMP-compliant facility. The certification goes a long way in improving consumer confidence. This powder has just one ingredient –creatine monohydrate. There are 2 main strains of creatine monohydrate: CreaPure and the standard monohydrate powder. ON uses CreaPure, a patented formula manufactured by AlzChem. It is the finest micronized, most potent and purest (99 percent pure) creatine currently in the market. CreaPure is free of by-products, damaging toxins and impurities like Thiourea, Dicyandiamide and Creatinine.

Besides being micronized (to reduce the size of particles), it is also odorless and tasteless meaning you can easily mix the supplement into any drink of your choice (water, juice or protein shake). This is the first thing you will notice about this product. Each serving packs 5g of pure creatine
monohydrate that enhances energy reserves in the muscles while reducing protein breakdown. The micronized formula lets you utilize a small amount of the supplement with great results.

Results may vary from one user to another, but common effects include enhanced muscle power and strength, better performance during high-intensity workouts, and faster recovery rates. Unlike other forms of creatine, this supplement causes fewer side effects. Side effects are mostly due to the slow absorption rate. Being micronized, this formula will be absorbed faster.

Final Verdict

ON Micronized creatine is as good as any standalone high-quality creatine brand can get. This superior product absorbs quickly and has less side effects. The only factor that makes a difference when buying a supplement is the brand behind the product, and knowing Optimum Nutrition, you’re in good hands. If you want to incorporate a creatine supplement into your training regime, ON creatine is the way to go!
