The Claim
Creatine uptake into skeletal muscle cells is mediated by the sodium-dependent transporter SLC6A8, which requires a sodium ion gradient for active transport.
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.
Your muscles use a special door called SLC6A8 to let creatine in, and this door only works when there’s more sodium outside the cell than inside — like a pump that needs salt to open.

What the research says
3 studiesStudy: Creatine uptake in isolated soleus muscle: kinetics and dependence on sodium, but not on insulin.
The study shows that muscle cells need sodium to take in creatine, just like the claim says. Less sodium means much less creatine gets inside the muscle.
Study: Cooperative Binding of Substrate and Ions Drives Forward Cycling of the Human Creatine Transporter-1
The study shows that creatine gets into muscle cells using a special doorway that only works when sodium is present, which matches the claim.
The study shows that the creatine transporter needs sodium to work properly, which supports the idea that creatine gets into muscle cells using a sodium-powered system.
