The Claim

The Na⁺/K⁺-ATPase pump maintains an electrochemical gradient across the cell membrane with higher extracellular sodium concentration, and this gradient drives the sodium-coupled transport of creatine via the SLC6A8 transporter.

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.

How it works
3 studies reviewed
In plain English

Cells use a special pump to create a sodium imbalance outside and inside the cell, and that imbalance acts like a battery to help pull creatine into the cell through a specific door called SLC6A8.

See the scientific wording

The Na⁺/K⁺-ATPase pump maintains an electrochemical gradient across the cell membrane, with higher extracellular sodium concentration, which drives the sodium-coupled transport of creatine via SLC6A8.

What the research says

3 studies
  1. Study: Cyclocreatine Transport by SLC6A8, the Creatine Transporter, in HEK293 Cells, a Human Blood-Brain Barrier Model Cell, and CCDSs Patient-Derived Fibroblasts

    The study shows that creatine gets into cells using a specific transporter that needs sodium, which supports the idea that sodium levels help drive this process, even though the study didn’t directly test the pump that sets up those sodium levels.

  2. Study: Regulatory effect of insulin on the structure, function and metabolism of Na+/K+-ATPase (Review)

    The study shows that the sodium-potassium pump helps maintain a balance of minerals in cells, which is needed for certain nutrients to get in, but it didn’t look directly at how creatine enters cells.

  3. Study: Cooperative Binding of Substrate and Ions Drives Forward Cycling of the Human Creatine Transporter-1

    The study shows that the creatine transporter uses the sodium difference across the cell membrane—created by the sodium-potassium pump—to bring creatine into cells, which supports the idea in the claim.
