Plant-based protein powders, like other sources of protein, can potentially cause constipation for some individuals. This is because protein is naturally less bulky and less fermentable than fiber, which are both factors that contribute to easier and more frequent bowel movements. Additionally, some people may have digestive issues with certain plant-based protein sources, leading to constipation.
The prevalence of constipation caused by plant-based protein powder is not well documented. To help prevent or alleviate constipation, it's recommended to drink plenty of water, eat a balanced diet with fiber-rich foods, and engage in physical activity. Additionally, taking a probiotic supplement and increasing the intake of magnesium-rich foods can also help with regular bowel movements. If constipation persists, it's best to consult with a healthcare professional.
