BlenderBottle might be most notable for mixing post-workout protein shakes. And it’s no secret that there are sometimes too many post-workout protein powders to choose from, each one insisting its better than the last, with some costing nearly twice as much for the same amount! Does it really make a difference? What are the types of protein powders to buy? These are common questions for any consumer.
Generally speaking, you’ll most likely be trying to decide between four types of protein powders/supplements: whey concentrate, whey isolate, soy, or casein.
Whey concentrate is arguably the most popular type available. It’s simply a concentrated form of milk protein that many use immediately after a workout. To be considered “concentrated” levels, 29-89% of the powder must be a complete protein enzyme.
Whey isolate, also derived from milk, is even more condensed, except with the powder required to be at least 90% protein. Many enthusiasts prefer isolate because it’s considered purer and offers less caloric filler than its concentrate cousin.
Soy protein comes from plants. If you suffer a sensitivity or an allergy to lactose, soy protein might be a better fit. Studies have shown that the benefits of soy and whey are practically identical, so it’s a solid alternative.
