The 0 one is a meta study. It goes deeper into Huntington's 30g, Parkinson’s, elderly with cognitive decline, and supplementing for help with memory related tasks. I didn’t dive deep into all either because I saw what applied to me and decided to see the results.

I think dividing the dosages throughout the day would help offset the stomach issues some and there have been 5 year long studies showing creatine doesn’t have any major risks with 5-7% people experiencing GI issues during loading phases.
