Whey protein can cause bloating in some individuals. Bloating is a common side effect associated with the consumption of whey protein, especially for those who are lactose intolerant or have a sensitivity to dairy products.
Additionally, some people may be sensitive to certain components of whey protein, such as lactoglobulin or lactalbumin, which can also trigger digestive issues like bloating.
If you experience bloating or other digestive discomfort after consuming whey protein, you may want to consider alternative protein sources such as plant-based protein powders like pea protein, soy protein, or rice protein. Alternatively, you can opt for 99% lactose-free whey protein isolates.
