How insulin helps cells pump salt and potassium
Regulatory effect of insulin on the structure, function and metabolism of Na+/K+-ATPase (Review)

Insulin tells cells to put more salt-and-potassium pumps on their surface, helping them move salt and potassium around faster — good for clearing lung fluid and keeping muscles working, but might help some cancers grow.
Surprising Findings
Insulin doesn’t just activate salt pumps—it prevents their destruction by blocking ubiquitination.
Most assume hormones only turn things on—but here, insulin acts like a shield against cellular recycling, a much more sophisticated and underappreciated mechanism.
Practical Takeaways
If you have lung issues or are recovering from illness, talk to your doctor about whether optimizing insulin sensitivity (via diet/exercise) could support lung fluid clearance.

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 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.
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.
Insulin might help cancer cells grow faster because some cancers have too many insulin receptors, and a specific protein called Na+/K+-ATPase β3 is linked to worse outcomes in liver cancer.
