Insulin helps open up blood vessels in your muscles, letting more blood through so nutrients like creatine can get to the muscle cells more easily.

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 helps blood vessels in muscles relax, letting more blood flow in. This brings more creatine to the muscle surface, where it can be absorbed.

85%

Insulin helps more blood flow to muscles in rats and people by using a substance called nitric oxide, which helps sugar get into muscle cells better.

85%

When you eat carbs, your body releases insulin, which helps shuttle creatine into your muscles more effectively—like a key that unlocks the door for creatine when sugar is around.

78%

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.

78%

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.
