There has always been a debate over which protein powder is better. Two most popular proteins available in market are whey protein and whey isolate. Both of these proteins are derived from same milk concentration and are amazing in their own way. To answer the question about which protein supplement is better for you, let’s first understand about them
Whey is simply the liquid by-product you get while making cheese. Once you remove water and casein content from this by-product, you are left with whey protein concentrate or widely known as whey protein. The most popular sports supplement now a days is whey protein because of its strong amino acid profile and absorption property. During the complete production process it is ensured that the protein stays intact and as pure as it can be.
Whey protein is rich in both BCAA’s and Glutamine. This makes it the ideal protein to help build muscle size, definition and aid recovery.
Whey protein has been shown to augment muscle protein synthesis, support fat burning, boost the immune system, improve insulin sensitivity, and decrease appetite.
While whey protein has a protein content of around 80-84%, the protein content of whey isolate is more like 90%. This is because whey isolate undergoes a process called Cross-Flow Micro-filtration. This separates the protein from fat, cholesterol and lactose yielding a purer protein as the end product.
Whey isolate is believed to have less fat, cholesterol, lactose, carbohydrates and calories than most other proteins on the market. It is therefore a common choice for those looking to maintain low levels of body fat but who still require the protein to help their muscles repair and recover. Although whey protein is already considered low in lactose, whey protein isolate is considered even lower because of the additional manufacturing processes. Whey protein isolate is therefore often recommended for athletes who suffer from lactose intolerance.
Things to keep in mind before choosing any protein
- What is your end goal
- Do you have any kind of allergy
Whey protein vs Whey isolate
If you perform intermediate workouts and want a general protein supplement that will help improve your health, will not break the bank and you are okay with lactose intake, pick a whey protein that has at least 80% protein. On the other hand if you are a hi-performance athlete or your have an intense workout regime, you’ll need a pure, rapidly absorbable whey for post workout that’s easy on the stomach too like whey isolate or whey hydrolysed isolate.
