The Claim

Creatine enters muscle cells through the SLC6A8 transporter in a process that co-transports sodium ions, leading to increased intracellular osmolarity, which drives passive water entry into the cell, resulting in cell swelling and enhanced intracellular hydration.

Supports is higher

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

How it works
1 study reviewed
In plain English

When creatine gets into muscle cells, it brings sodium with it, which pulls water into the cells and makes them swell up a bit — like a sponge soaking up water.

See the scientific wording

Creatine entry into muscle cells via the SLC6A8 transporter is coupled with sodium influx, increasing intracellular osmolarity and driving passive water influx, resulting in cell swelling and enhanced intracellular hydration.

What the research says

1 study
  1. Study: Regulation of intracellular creatine in erythrocytes and myoblasts: Influence of uraemia and inhibition of Na, K‐ATPase

    The study shows that creatine gets into cells with the help of sodium, which supports the idea that it can pull water into cells. It doesn’t directly measure swelling, but the first part of the process checks out.
