The Claim

Short-term creatine monohydrate supplementation (20 g/day for 3 days followed by 5 g/day for 7 days) causes upregulation of genes related to cytoskeleton remodeling, including COL5A3 and FLNA, in the skeletal muscle of healthy young men, suggesting structural reorganization due to cellular swelling.

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

How it works
1 study reviewed
In plain English

Taking creatine for a week might change genes in young men's muscles that help reshape the muscle structure, possibly because the muscle cells are holding more water.

See the scientific wording

Short-term creatine monohydrate supplementation (20 g/day × 3 days, then 5 g/day × 7 days) causes upregulation of genes involved in cytoskeleton remodeling, such as COL5A3 and FLNA, in skeletal muscle of healthy young men, indicating structural reorganization in response to cellular swelling.

What the research says

1 study
  1. Study: Global and targeted gene expression and protein content in skeletal muscle of young men following short-term creatine monohydrate supplementation.

    The study gave young men the same creatine doses mentioned in the claim and found that genes involved in muscle structure changes were turned up, which supports the idea that creatine causes muscle cells to reorganize due to swelling.
