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

Gritty Drinks

Does not mix into your drink week and leaves it being very gritty. It may work better in a hot drink but I'm not willing to sacrifice my coffee to grittiness.

Creatine is a product that does not fully dissolve, so rest assured that this is completely normal. Note that creatine should be consumed immediately upon mixing.

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

Convenience

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

GRITTY!

SO SO gritty and would dissolve all the way. And there's no scoop!

Easy way to take creatine!

Product was great, never felt bad about having to take it as pill form. So much easier

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.

Brain power, muscle power, feeling good

I've always really liked the benefits of creatine but I find that this brand seems to not hurt my belly as much.

No scooper

Does not come with a scooper. Wants to to carry around a spoon with you. Hope they saved a lot of money not including one. Will not buy again.

Better brands available

Creatine does not mix at all and is very gritty. Other brands at least mix a little bit. This container does not come with a scoop either.
