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.

Best Customer Service!!

I tried the Caramel Coconut cookie that everybody was raving about because I have a weakness for the Girl Scout Samoa cookies. Unfortunately it was a bit to sweet for me but I tried for weeks to see if I could adjust. I was ready to give up but I decided to contact Jared (the owner) to see if there was any option for an exchange. He is what every business should model. Not only was his response prompt, but he was bending over backwards to do whatever he could to try to give me other options without any expense to me! That ALONE will make me try every product on this website because it is so difficult to find great customer service…especially lately!! Support this business! He deserves it! Also, they included so many samples with my original order I was able to try just about everything so I know what to order next! This company is for the consumer!

Whipped Banana Cream

Very chalky. Other whipped flavors are fine.

Pretty delicious, bur I do wish it had more of a coconut and caramel flavor. But to me it's just sweet (but still yummy!) Mixes easily and smells amaaaazing

Antonis M.

Tastes artificial if I’m honest, tried the sample pack.

Just as good, but better than Girl Scout cookies

I put this in my morning coffee, instead of creamer. I put it in my plain lowfat Greek yogurt, edible cookie dough, and in shakes. Super delish! I need the extra protein between meals. Love this stuff!


How are all of the flavors amazing? I’ve tried milk chocolate, banana, strawberry, blueberry, & coconut and every single one of them is soooo good. Like the absolute best tasting protein out there. Thank YOU for making this. I have a subscription now and will try the other flavors as well. Yum!
