Whey is a type of protein derived from milk that is processed to reduce its fat and lactose content, leaving mainly proteins.
Whey protein isolateis a more refined form of whey protein concentrate, which has been further filtered to remove most of the lactose and fat. It is an excellent low-calorie option for bodybuilders, those who control their weight, or even those who are lactose intolerant. Nutrition experts suggest that you limit the amount of processed foods you eat, and that includes some whey products and whey isolates.
If you have lactose intolerance, whey isolate is a better choice than whey concentrate. Much of the lactose and sugars are removed from whey isolate during processing. However, if you are allergic to dairy products, both whey and whey isolate can cause stomach discomfort. In that case, look for plant-based proteins instead.
When selecting between whey protein or protein isolate, you'll need to consider the following factors to help you decide which whey protein is best for you: its purity, its fat and lactose content, its cost, and its flavor. Whey protein isolate contains little or no fat, cholesterol, carbohydrates and lactose. It has protein concentrations that exceed 95%, so it is essentially a dietary supplement with pure proteins. Advanced Essential Whey is a unique blend of both proteins for those who don't prefer a high quality isolated and healthy whey protein concentrate. Many whey products and whey isolate products contain added sugar to improve their flavor.
Check labels for sugar and processed ingredients, such as artificial flavors. As the most ubiquitous supplement in existence, the popularity of whey protein powder is unrivaled by athletes and weightlifters of all levels. The truth is that most adults don't digest lactose well, but that doesn't matter because whey protein isolate contains such a minuscule amount that it probably won't affect you. If you experience annoying gas, bloating, nausea, cramps, headaches, or stomachaches while using whey protein isolate, it may be best to stop consuming whey protein and try a different source of protein as a supplement.
