Overconsumption of protein supplements can lead to digestive problems such as bloating, gas, diarrhoea, and stomach cramps.
Excessive protein intake can put a strain on the kidneys, potentially leading to kidney damage or exacerbating existing kidney conditions.
High protein diets can increase the need for hydration as the kidneys require more water to process and eliminate the by-products of protein metabolism, potentially leading to dehydration if fluid intake is not increased simultaneously.

Some protein supplements contain high levels of saturated fats or added sugars, which can negatively impact heart health by increasing cholesterol levels and contributing to cardiovascular disease.
