Convenience

Easy and convenient to swallow the pills rather than to mix the powder with a drink

As part of ON's effort to be environmentally conscious and reduce plastic, our Creatine Powder does not come with a scoop. The serving size for this product is one rounded teaspoon.

Great bang for your buck! Only annoying thing is it doesn’t come with a scoop.

Did not dissolve in water and made my stomach upset everytime I used it.

We appreciate your honest feedback, we’re sorry to hear the mixability didn’t work for you. We recommend checking out our new creatine releases like Creatine Gummies!

Great product. Dissolves well in water. I’ve noticed increased stamina on runs and faster recovery times.

Truly flavorless, but does not dissolve

It truly is flavorless and I’m starting to see a difference in my workouts after just a few weeks of consistent use, however it does NOT dissolve in cold liquids. I was trying to drink it with just water and while it tastes like nothing, you can feel the grains in your teeth so I highly suggest mixing it in a smoothie or protein shake, otherwise it’s great! I will definitely continue to buy and use it.
