Optimum Nutrition Micronized Creatine Powder Review Review Facts

One of the most frequently used muscle boosters is the Optimum Nutrition Micronized Creatine Powder which is creatine monohydrate - highly valued as one of the safest and purest muscle boosters.

The first thing you need to know is that this is not a steroid nor it's a drug that is going to interfere with your natural metabolism or your daily lifestyle. This question has often been discussed in forums or social networking sites, so we felt the need to address it right away.

In addition to increasing the lean body mass, it is used for treating some medical conditions such as creatine deficiency syndromes that impact the brain, bone density, congestive heart failure, aging, Parkinson's disease, muscles and nerves diseases, etc. However, the most frequent use is found in improving the athletic capabilities of healthy people during intensive exercises and for adding extra muscle mass.

Creatine monohydrate is an amino acid derivative which functions as a substitute for fuel that is primarily found in the skeletal muscles and the brain - we get it the food we eat, particularly red meat and seafood.

Since it has been permitted for use by the International Olympic Committee and National Collegiate Athletic Association, we feature this creatine powder as one of those supplements that can help you increase your muscle strength and endurance. 

Editor's Pros & Cons

Pure micronized creatine monohydrate

Ensures maximum potency during your workouts

It increases lean muscle mass

Easy to dissolve and easy to absorb



Chalk-like taste

It can cause some kidney-related health issues


As expected, it's most common use is to enhance the physical performance of athletes by adding more muscle mass and strength, even endurance.

When used by seniors, it has greater results as it helps to reactivate and increase the lean muscle mass, improve the overall physical ability, and increase the ability to perform more than just basic daily activities.

The science behind supports the use of creatine to enhance people's physical endurance during high-intensity workouts as it affects only the lean muscle mass and has no influence on body mass whatsoever.

Micronized Creatine Powder is also used as a recovery product and as an after injury treatment, as it helps muscles regain the tissue and repair any tears.

In addition to being super beneficial for athletes’ performance, it is shown to have some advantages in treating a wide range of medical conditions, most of which imply lowered or lack of creatine.

There’s particularly one group of people who will benefit the most from taking creatine and that is vegetarians and vegans. Since creatine is mostly found in meat, many vegans and vegetarians may experience low levels of creatine in their bodies. When they add creatine to their diet, it will help increase creatine levels in muscles.

Use and Dosing

When it comes to frequency of use and the amount needed to enjoy the benefits of this product, users need to follow the instructions and recommendations provided by the manufacturer.

Sometimes, in case of health issues, it is advisable to discuss the use with your doctor prior to taking the Micronized Creatine Powder since it can cause adverse reaction in case there’s an intolerance.

When you first start using the Micronized Creatine Powder, you need a dosing protocol so that your body gets used to it and loads for almost immediate effect. Mind you though that a single or a very short-term use won’t provide any benefits; you need at least a week’s use to notice any effects.

The dosing protocol for first-time users includes taking 20 grams daily until the body reaches an optimum level of creatine, and then gradually lower the dose to roughly 5-6 grams to maintain said level. Those who’ve been taking it, they just need the maintenance dose of 3-6 grams a day.

The optimum result can be seen after two to three months when users can expect an increase in the lean muscle mass, in their physical strength, and endurance.

When to Use It

Optimum Nutrition Micronized Creatine Powder is recommended for post-workouts. Also, most of the study data suggest that if you are using it periodically or preparing for competition/intensive workouts, post-workout is more recommended.

The reason behind this is that beginners and irregular users don’t have sufficient and stable creatine levels, so when you take it after high-intensity exercises it will directly affect your muscles and help repair them.

On the other hand, if you are a regular user who’s been taking about 5 grams a day, then it makes no difference whether you take it in the morning, pre-workout or post-workout.

How to Use It

This creatine product comes in the form of a powder, so it can be dissolved in any type of liquid. We have to refer to the user's comments who claim that it is a bit hard to dissolve, so you need to be extra patient to wait for it to naturally dissolve on its own.

Many athletes, particularly those who have decided to use it post-workout, mix it with their protein shake or energy drink. In addition, it can be added to caffeine drinks and juices since it has no taste whatsoever. Blended in juices it will surely modify the structure of the liquid by making it more chalky, so this is the least favorable option.

To ensure you're taking 5 grams, the package comes with a rounded 5-gram spoon, so the only thing you need to do is fill the spoon and add the powder to your drink of choice.
