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

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

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

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.


Casein protein also comes from cows. The primary difference between casein and whey comes in the release pattern. Many body builders use casein due to its slow release pattern, but generally not immediately following a workout, since it has such a slow absorption rate. It’s usually consumed before bedtime, so it can be slowly released during sleep. If you’re on a budget, the less costly proteins do the trick, they just have less protein content per gram and more sugars and carbs. Always be sure to check the nutrition labels for any added ingredients. If you’re looking to gain mass, consider a whey protein packed with calorie-dense high-carbohydrate ingredients, but do so only at the advise of a professional.
