The Different Body Parts Insulin Stimulates

3. Absorption Of Amino Acids And Potassium

Amino acid and potassium supplementation would be greatly decreased without insulin to help absorb it into the bloodstream. Insulin increases the permeability of many cells to potassium. In other words, it allows potassium to cross over cellular membrane into cells where it is needed for many functions. When amino acid levels are low, such as in a state of fasting, insulin helps stimulate the uptake of amino acids by pushing the balance toward intracellular protein degradation, or the breakdown of protein into amino acids.
