Blender Bottle 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 proteins to buy? These are common questions for any consumer.
Generally speaking, you’ll most likely be trying to decide between four types of protein 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.
