Whey protein powder is generally considered safe for most people when consumed in moderation as part of a balanced diet. Whey protein is a high-quality, complete protein that is commonly used in supplements and protein powders, as it provides the body with essential amino acids needed for muscle growth and repair.
However, some individuals may be intolerant or allergic to lactose, which is a sugar found in dairy products, including whey protein powder. Consuming whey protein powder can cause digestive symptoms such as bloating, gas, and diarrhea for individuals who are lactose intolerant. Additionally, people with a dairy allergy should avoid whey protein powder.
In conclusion, whey protein powder is generally safe for most people when consumed in moderation as part of a balanced diet. However, it's always a good idea to check with your healthcare provider, especially if you have any pre-existing health conditions or dietary restrictions.
