Gritty and doesn’t dissolve

I’ve taken several brands of creatine. This is the worst creatine I’ve ever taken due to its grittiness. It doesn’t dissolve at all, even when mechanically blended in. It’s so bad I’m going to try to return it

Convenience

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

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!

The ease of mixing in my water or drink with no flavor is awesome. This is a great quality product.

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

Great alternative to powder

The tablets are on the bigger side but that's unavoidable and they're easy to take as part of a routine.

Stomach problems

I bought this product and have been using it a week so far at recommended dose. This brand causes me stomach issues and I have to quit taking it. Other brands have not caused me discomfort before so I have to swap back. I love this company, but this product was a waste of money for me sadly and I cant return it since been used.

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.
