Supplementation with pea protein for 84 days in sedentary adults does not cause clinically relevant changes in liver, kidney, or hematological markers, and the rate of adverse events is comparable to that observed with whey protein supplementation.

When pea protein is eaten, it breaks down into amino acids that the body uses to build and repair muscle, just like whey protein. The liver and kidneys process these amino acids normally without becoming overloaded, and the blood shows no signs of damage or imbalance. The body handles pea protein the same way it handles other high-quality proteins, so no harmful changes happen in the liver, kidneys, or blood cells.
