Whey protein is known in the fitness world as a key ingredient to build muscle, but there are whey protein dangers to be aware of. When you know the dangers of whey protein, you can better choose the right product to use for your specific goals. Speak with your doctor before starting any new supplement or fitness routine.
- What is Whey Protein? Whey is a derivative of milk curd collected during the cheese making process. It's a perfectly natural substance. The curd is turned into powder and other ingredients and flavors are added before it hits the fitness market. Whey makes up about 20 percent of store-ready milk. Drinking large quanitites of milk can also provide you with the affects of whey protein.
- Potential Kidney Damage. Because whey protein is difficult to digest, it can have a negative long-term effect on the kidneys. The side effects and symptoms often go unnoticed until there is a serious problem. This problem can present itself as kidney failure. This can be caused from excessive use of a whey protein shake powder. This isn't likely to be a problem for those who use whey protein over a short period time or occasionally, but can potentially surface in those who use the protein source on a regular basis.
- Potential Liver Damage. Because the liver also aids in digestion, it can be negatively effected by overuse of whey protein. The impact of whey protein on the liver is different for each person because liver function may vary. It's important to find protein from a variety of natural sources and not solely rely on whey protein supplements for muscle building.
- Osteoporosis. The long-term consumption of whey protein can contribute to mineral and vitamin imbalance in the body. This can lead to a difficiency of bone density and thus osteoporsis. While you can add more calcium and vitamin D to your diet to help counteract this, it will not protect you from the overall harmful effects of whey protein.
- Recommended Dosage. The liver and kidney problems come from the overusage of whey protein. If you drink milk and whey protein shakes on a daily basis it can be easy to go over the recommended dosage. Many bodybuilders also increase the recommeded dosage of whey protein shakes looking for faster, better results. Most whey protein powders recommend no more than two to three doses per day. Many bump this up to five or six and make the shakes with milk. The minor side effects from too much whey protein are gas and upset stomach. Many people don't experience this at all. Because of the lack of side effects, you may not know about the damage until you are seriously ill.
