Whey Concentrate Vs Whey Isolate



Being one of the two major components of milk, whey is the liquid that is separated from the curds when you make cheese. Whey is packed with proteins, carbohydrates, minerals, and fats, making it an essential addition to any athlete’s diet. It’s also the most popular sports nutrition supplement, and has been shown to greatly augment muscle protein synthesis, boost the immune system, decrease appetite and improve insulin sensitivity. It also boosts the production of glutathione.

Whey protein comes in three forms: isolate, concentrate, and hydrolysate, and this time we will be focusing on the differences between concentrate and isolate – both forms contain whey protein, but isolate undergoes further processing which, in the end, results in more protein per unit than concentrate.

So which one should you choose? There is a number of reasons why both options are good and why one is better than the other. It’s important that you carefully analyze your goals, budget, and, most importantly, any allergies you might be suffering from.

Whey concentrates, for instance, are lactose-heavy, so anyone who is lactose intolerant should stay away from them. Isolates are processed more, so they are usually more expensive and lose some of the health-promoting benefits that concentrates have – but they have a higher amount of protein per unit, which is important for people who count their calories and wish to stick with as much real food as possible. Isolates are more rapidly absorbed and create a more profound insulin response, which makes them a popular post-workout choice.

The conclusion? If you want a general protein supplement that won’t rip your wallet into pieces, take a concentrate with at least 80% protein. If you want rapid absorption, and you don’t care that much about the health benefits or the price, you should opt for an isolate.
