the science

Isothority is a cross-flow cold-microfiltered whey protein isolate. Sounds fancy, right? Let's break it down: Isolate is the purest form of Whey Protein available. You get less filler, carbs, lactose, etc. This means it also digests much more easily without stomach issues.

The method by which the protein is extracted is much more precise. Rather than using extreme heat, acid washes, and other harmful processes, we utilize a filtration system to isolate the protein.

This leaves an incredibly clean protein that is easy to flavor, has a great texture, and digests extremely well. There truly is not another protein that is this pure, and tastes this good.

Who is it For?

Everyone. If you are exercising, restricting your calories, or cleaning up your diet - you'll benefit from Isothority. Isothority is especially important after your workout as it will help you recover faster, be less sore, and boost your metabolism.

What Will I notice

This is a tricky question. Here's another way to look at it: What would you notice from eating a chicken breast, or egg whites? In general, you will be less sore after your workouts. Your body will adapt and gain strength and endurance much more easily. You'll also boost your metabolism and stave off hunger more easily when taking a quality protein source in.


How do I use it?

The most important time is after your workout - 1 scoop mixed with 6oz of water (or milk) will do it for most everyone. It can also be utilized at any other time you would need a protein source; as part of a meal, as a milk shake, or just to increase total protein intake for the day.

Great taste!

This mixes well and has a really good taste, so far all of the flavors that I have tried have been spot on. This one is kinda rich though so for me personally, I’d rather have a fruity flavor if I’m drinking the same flavor every day.

Love Isothority

I’m a new customer and have ordered twice so far, sample packs and then two canisters of isothority. I’m very impressed and will continue to order. The items are shipped very quickly! I’ve loved all of the flavors I’ve tried so far. I blend my shakes and they come out super creamy! I was in a slump and didn’t want to eat protein shakes, since switching to isothority, I’m back to consistently having them.

Tastes Amazing

I am very happy with my purchase. I only bought a trial packet because I didn't want a huge container if I didn't like this product. However, I LOVE it. The taste is great and there is no grit at all.

We appreciate you and your review Brandi!!! Welcome to the family :)

Churro & Peppermint Mocha were okay

peppermint mocha tastes metallic in a way, I don’t get too much rich mocha flavor in there unfortunately so I won’t be buying that flavor unless they adjust the formula. Churro was okay but nothing special, not too much cinnamon or actual churro flavor. Caramel coconut is the best flavor so far! And the tropical pre workout tastes yummy.

Hey Lexi, happy to hear you like the flavors of some of the products!!

Carmel Coconut Cookie

I really like this protein. It mixes easy with a shaker and ball without having to blend it. The flavor is great, as I mix mine with coffee in the morning. I’ll be buying more after I finish what I bought.

Happy to hear you are loving it Samanatha!!!!
