Yes, it is possible to overdose on protein powder. Consuming too much protein can lead to a number of adverse effects, including digestive problems such as nausea, abdominal pain, and diarrhea, as well as dehydration and imbalances in electrolyte levels.
Additionally, consuming high amounts of protein can put a strain on the kidneys, especially if an individual already has kidney problems. Excessive protein intake can also lead to the production of excess nitrogen in the body, which can be harmful if not properly excreted.
If you are considering using protein powder, it is recommended to consult with a healthcare provider to determine the appropriate dose and to monitor for adverse effects.
