It can be difficult to choose a whey protein supplement when faced with different types and brands in the market. When it comes to taste, amino acid profile and digestibility, whey protein really is the top muscle gain supplement choice for many people, with whey concentrate and whey isolate being the top two. However, which of the two is ideal for you.
The Difference Between Whey Concentrate and Whey Isolate
The top-selling whey protein forms are whey isolate and whey concentrate, Musashi notes. Primarily, the difference between the two is purity, such that isolates are purer than concentrates because non-protein components in whey isolate have been eliminated to ‘isolate’ the proteins.
The majority of whey concentrates contain 80% of protein, meaning that 80% of the overall weight when dry is pure protein. For example, 100 grams of concentrate has approximately 80 grams or protein, 400 calories, 150 milligrams of cholesterol, 6 grams of fat, and 9 grams of carbohydrates of which half is lactose. On the other hand, whey isolates contain around 90% of protein, or 90 grams, so protein content is increased for every 100 grams. Additionally, you only get roughly 370 calories and significantly reduced cholesterol, fat, lactose and carbohydrates.
If you’re not sensitive to lactose and you’re looking for a great protein supplement for overall health and weight management and have little money to spare, go with whey concentrate. On the other hand, if you have lactose intolerance, need more of a protein punch for your training, but fewer carbs and fats, and you have money to spare, go with whey isolate.
