Or perhaps there is something lacking in the brand that does not help them sleep? By that I mean maybe there is less creatine than claimed, or it is supplied in a form that is harder to digest.
Really hard to know, but the creatine that didn't seem to help was a cheaper, bulk buy. My guess is that it wasn't as much creatine as it said. Unfortunately, I feel like there is a lot of misrepresentation around supplements.
