There are no fillers in this creatine monohydrate. The only ingredient is Creapure. The simplicity of the ingredient list helps keep the cost down and makes ON’s Creatine one of the cheapest and highly rated creatine supplements available. The powder supplement is odorless and tasteless, making it easy to mix with other powdered supplements.

99.9% creatine monohydrate unflavoured powder. At 114 servings, this container is a better value by the ounce than many competitors. Contains 5 grams of creatine monohydrate per serving.

Most users noticed that after a week of using Optimum Nutrition Micronized Creatine, they noticed a difference in their workouts at the gym; they were able to add on more reps, use heavier weights, have a shorter recovery time, and noticed a visible increase in the overall size of their muscles.

This powder is tasteless making it easy to mix into drinks and recipes. Each serving contains 5g of creatine and for a 600g tub, the price is still cheaper than the average tub of protein powder.
- Wear Action
This creatine powder can also increase your energy levels and quicken your recovery time by enhancing the energy reserves in your muscles while minimizing protein breakdown.
- Cure Disease
This is best recommended for post-workout use.
- Pure Path

This unflavored micronized creatine powder is available in a choice of two different sizes so you can try a little or a lot, at a price that works for you.

This has pure micronized creatine monohydrate.
- Garage Gym Power
It mixes very well and can be blended with a shaker bottle. There are no fillers or additives in this product.
- Garage Gym Builder
Since every bit of this micronized powder is so tiny, the supplements quickly dissolve in any type of liquid, so you will be able to mix them with any drink, be it juice or water and experience the effects sooner rather than later. It will increase your evergy levels and speed up the recovery rates.

It’s incredibly affordable. While Integrated Supplements Creapure Creatine is technically the cheapest Creapure.
- Mantelligence
The fact that it’s micronized means this powder can dissolve in water with less clumping. It can be made into post-workout shakes and more. This ON supplement doesn’t have any filler and is true to its claim of being pure. It’s relatively safe to take, but if you’re under 18 or pregnant/nursing, make sure to consult a medical expert first.

What experts didn't like

The biggest overall complaint by users of ON Creatine Powder is the lack of a scoop for the powder in the package. Instead of providing a scoop, Optimum Nutrition instructs consumers to use a rounded teaspoon to measure the recommended serving of five grams.

Does not include with a scoop.
- BestReviews
The biggest downside that a lot of people complain about with Optimum Nutrition Micronized Creatine is that the powder doesn’t mix in well.
- Alt Protein

It comes as a flavorless powder. So some might not really like the bland taste it gives when mixed with water. But if you are looking for a creatine supplement that you can combine with your other post workout shakes then this is the best option.
- Beasts Live

Product recommends taking at least three times a day, which is more than most creatine supplements. Also, it doesn’t offer any obvious guarantees about the product being vegan, non-GMO, etc.
- Cure Disease
Unflavored powder may not taste great on its own. This may not mix as well as other powder products.
- Pure Path
No measuring spoon included.
- Garage Gym Power
This is tasteless.
- Garage Gym Builder
The container's design is a tad inconvenient, might be difficult to get the last bits of powder with a spoon.

An Overview On

Looking for a little boost for your gym time or sports workout? Creatine is a supplement that can help you. With muscle building attributes, creatine is an ideal substance for those who are performing heavy lifting or exercise that is high-intensity.

Kristin Forte/Simplemost Media

There are countless natural substances found throughout your body. These substances are there to help your body function properly for everyday living. Some of these substances are depleted when you push your body to extremes with things like childbirth, extreme workouts or even a very physical occupation.

Creatine is one of those substances needed for your muscle cells to function at their max capacity. It encourages the production of energy in your muscles. It has similar characteristics to amino acids and can be made from glycine and arginine, two common amino acids.

Kristin Forte/Simplemost Media

The consumption of meat, hormone levels (especially testosterone) and exercise affect the boy’s creatine levels. It is stored mostly in the muscles as phosphocreatine but a small percentage can be found in the liver, kidneys and brain.

What happens when you take the supplement is an increase in the phosphocreatine, which becomes energy stored. This stored energy then produces ATP or Adenosine Triphosphate, an energy carrier in most living things. When you eat or your body absorbs energy through light, it is stored as ATP for when you need to use that energy. When your body needs that energy, it then breaks down ATP through hydrolysis. Through this process, the bond is broken, and the phosphoryl group is eliminated, in turn releasing energy for the cells.

Kristin Forte/Simplemost Media

In addition to increasing energy, creatine accelerates recovery in your muscles and even increases muscle mass. How does creatine do these things? It allows your body to endure through longer periods of extreme exercise which helps your muscle grow. It also increases cell signaling that helps with muscle growth and more importantly muscle recovery. Finally, creatine elevates water levels in the cells, which not only helps with the function but also plumps the muscle up.

Taking creatine is shown to significantly reduce the breakdown of proteins that comprise our muscles. It encourages the growth of the muscle by lowering myostatin levels, the protein that can prevent muscle growth. Additional studies have found that the increase of phosphocreatine in the brain enhances function and can prevent neurological malfunctions.

Creatine can have other benefits, too, says Dr. Niket Sonpal, a doctor based in New York City.

“Sleep deprivation has a negative effect on mental performance and mood. This can be caused by a drop in creatine levels in the brain,” he says. “Studies suggest that taking a creatine supplement can help to offset the decline in mental performance that normally happens when you’re short on sleep.”

Importantly, Dr. Sonpal advises talking to your doctor before you begin taking supplements of any kind, including creatine. And keep in mind that if something sounds too good to be true, it likely is.

“Always check with your physician before adding any supplement to your diet.  Do not expect miracles from any product. A sensible, healthy diet and regular exercise program are the real keys to achieving and maintaining weight loss and overall health,” he says.

So how do you consume creatine supplements? Most consumers use a powder form of creatine that can be mixed into beverages or smoothies. There are a few different varieties to choose from, but most of them are monohydrate variations. You will find different potencies to accommodate the level of exertion you plan on performing.

With several different potencies, you can start with the lowest strength of the Optimum Nutrition Creatine and work your way up if need be. This Keto-friendly powder won’t disturb your dieting and will enhance your muscle mass and energy levels.

For a pH balanced option that won’t affect your GI tract, you’ll want the patented EFX Cre-Alkalyn Creatine. This has a pH level of 12 to prevent all the noted bloating and cramping associated with creatine supplements.

With the concern of different diets these days, there are now vegan-friendly options as well. The Creatine Monohydrate Powder Micronized by BulkSupplements leaves you feeling good with its vegan-friendly claim and pureness of the supplement.

When you want the purest creatine, MuscleTech Platinum Creatine delivers. With a no sugar, no filler, pure-as-can-be formula, this creatine will surely give you the muscle gain you want without the added ingredients.

Creatine is a great supplement to take if you are working towards a physical achievement or goal. Your muscles will thank you both during and after the workout session, and you won’t feel as much strain on your muscles when used. Find the dosage that works for you and see the results for yourself.

The Creatine Buying Guide

  • Creatine should not be abused. Your body makes enough creatine, naturally and through the foods you eat, to support everyday functions, so this supplement is really specific to those athletes that are going above and beyond.
  • Make sure to always consult a health professional and discuss safe doses for your body before starting on any amounts of creatine.
  • Although most of the powders are unflavored, it is always more pleasant to add this supplement to a shake or smoothie.
  • Make sure to explore the options that best suit your diet, whether that means vegan, low-sugar or even Keto-friendly.
  • When you experience adverse side effects, talk to a medical professional before continuing on a regiment.
