Can People having Kidney Stones Problem Take Whey Protein I suggest that you speak to your doctor before starting any supplement. They will be able to guide you based on your current situation. No matter what supplement we plan to take, we should always talk to a professional and not self-medicate. Whey protein is the protein that is got from milk, after the cheese-making process. It is of three types - concentrate, isolate and hydrolysate. These days, there are many whey protein supplements available in the market. There are flavoured as well as unflavoured. When protein, when consumed in excess, has to be eliminated from the body and this elimination process happens through the kidneys. There is only so much protein a person can absorb, and the excess has to be removed from the body. When you consume a lot of whey protein daily, your kidneys get stressed and have to work overtime. This can cause problems. Another thing is that protein supplements do contain a lot of additives that can additionally cause problems to the body. Many brands add a lot of additives. Always read through the additives and find out more about them. Some common additives are artificial colors, artificial flavours, artificial sweeteners (Erythritol, Acesulfame Potassium, Saccarin, Aspartame, Sucralose, etc.), Gums & Thickeners, Vegetable Oils & Fats, etc.
