Pea protein powder, like other protein powders, can cause digestive issues, including diarrhea, in some individuals. This is because some people may have difficulty digesting pea protein, leading to gastrointestinal discomfort and diarrhea. Other factors that may contribute to digestive issues with pea protein powder include an individual's tolerance to plant-based proteins, the quality of the pea protein powder, and individual differences in gut bacteria and digestive function.
Additionally, consuming too much protein powder in a short period of time, especially if not well hydrated, can also lead to digestive discomfort and diarrhea.
If you're experiencing digestive issues with pea protein powder, it's best to speak with a healthcare professional to determine the cause and receive appropriate treatment. You may also want to try reducing your intake of pea protein powder or switching to a different type of protein powder to see if it improves your symptoms.
