Effect of insulin upon membrane‐bound (Na+ + K+)‐ATPase extracted from frog skeletal muscle.

Cross-Sectional Study

Animal

1975 Oct

Insulin boosts a molecular pump in muscle cells that helps move sodium and potassium. This study shows that insulin makes this pump work harder, which supports the idea that it could help bring more creatine into cells.

The study shows insulin makes the sodium-potassium pump work harder in human muscle cells, which supports the idea that it could help pull in more creatine using sodium as a helper.

Narrative Review

2021 Nov

The study shows insulin boosts a cellular pump that helps control sodium and potassium, which supports the idea that it could help cells take in more creatine using that pump.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

When insulin is present, it tells muscle cells to pump more sodium and potassium around, which creates a better environment for the cell to pull in more creatine — a compound that helps muscles store energy.

Insulin helps your muscles take in more creatine by making blood flow better and boosting a pump-like system in muscle cells, which helps bring in more nutrients.

When you eat, your body releases insulin, which helps muscle cells pull more potassium from your blood by putting more pumps on their surface—this keeps your muscles working smoothly after meals.

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.

When you take creatine with carbs, it helps your body hold onto more creatine because the carbs spike insulin, which helps shuttle creatine into your cells better.
