The Claim
In healthy young men, five days of creatine supplementation at a dose of 20 grams per day increases total muscle creatine content but does not affect muscle glycogen levels during or immediately after exhaustive cycling exercise, indicating that elevated muscle creatine stores alone do not enhance glycogen utilization or preservation during endurance-type activity in the absence of prior glycogen-depleting exercise.
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.
Taking creatine for five days boosts creatine in muscles, but doesn’t change how much glycogen (energy) is used during intense cycling in healthy young guys — so more creatine alone doesn’t help save energy stores during endurance workouts if muscles weren’t already drained.

What the research says
1 studyThe study found that taking creatine for 5 days fills up creatine stores in muscles but doesn’t change how much glycogen is used or saved during intense cycling, which matches what the claim says.
