The Claim

In healthy young men, supplementation with 20 g/day of creatine combined with a high-carbohydrate diet increases muscle total creatine content by 9% after 1 day, 14% after 3 days, and 24% after 6 days following exhaustive exercise, with significantly higher levels compared to placebo at each time point.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

If young, healthy guys take a lot of creatine with a high-carb diet after a tough workout, their muscles store more creatine within just a few days — and it keeps going up the longer they take it.

What the research says

1 study
  1. Study: Creatine ingestion augments dietary carbohydrate mediated muscle glycogen supercompensation during the initial 24 h of recovery following prolonged exhaustive exercise in humans

    The study shows that taking creatine with lots of carbs after tough exercise boosts creatine levels in muscles more than a fake pill, just like the claim says.
