It is better to depend upon natural sources of protein rather than powder protein. Powdered whey proteins contain very high amount of protein that may cause damage to basement membrane of kidney cause loss of precious protein from our body (proteinuria). Also most of these whey proteins contain high amount of creatin which may cause hypertension (high blood pressure) and other side effects of high blood pressure. So avoid these powdered food supplements and depend upon natural sources of high protein such as egg, chicken, cheese, soybean, dry fruits and dairy products Thanks
