PROTEIN ISOLATE: Isolate: Generally goes through a defined filtration process yielding a higher content of protein: 90% protein, or higher. Because of this, it contains less lactose and fat than normal whey concentrate.
ESSENTIAL AMINO ACIDS: All nine essential amino acids perform varied roles in your body. They’re involved in important processes such as tissue growth, energy production, immune function, and nutrient absorption.* Supplementing with EAAs could reduce muscle soreness after exercise.
DIGESTIVE ENZYMES: UXO uses DigeZyme as our digestive enzyme. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases to break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases. Breaking protein down allows for it to be digested more efficiently and put to use faster for more lean muscle gains.*
Unlock your full potential with POST ISO, the ultimate in protein purity and performance. Designed for the fitness enthusiast who demands excellence, this fast-digesting whey protein isolate is your go-to for maximum absorption and results without compromise.

Improved absorption and digestion for those who have issues with other whey protein sources. Hit your macros and feel good. †
AMAZING FLAVORS
We pride ourselves in nailing the flavors. We realize if it doesn't taste exceptional, people aren't going to want to drink it. So we go the extra mile with every flavor launch.†
Protein is one of the most powerful nutrients for athletes—vital for building lean muscle and accelerating recovery after intense training. But it’s more than just a post-workout add-on; your body depends on consistent daily intake to perform and grow. Aim for roughly 1 gram of protein per pound of body weight each day to fuel strength and repair. Alongside whole-food meals, UXO Whey Protein Powder makes it easy to hit those numbers, delivering clean, high-quality protein to keep your muscles fed and progress on track.

Frequently asked questions

Whey protein isolate is a highly refined form of whey protein that has undergone additional processing to remove most of the fat, lactose, and carbohydrates. This results in a protein powder that is typically 90% or more protein by weight, making it a great choice for those looking to maximize protein intake while minimizing extra calories.
It is fast-digesting and rich in essential amino acids, particularly leucine, which plays a key role in muscle protein synthesis. Because it contains little to no lactose, whey protein isolate is also a good option for people with lactose intolerance. It's commonly used for muscle recovery, lean muscle building, and overall protein supplementation.
The main difference between whey protein isolate and whey protein (often referring to whey protein concentrate) is the level of processing and protein content.
- Whey Protein (Concentrate): Contains 70-80% protein, with more fats, carbs, and lactose. It retains more natural nutrients and can have a creamier texture.
- Whey Protein Isolate: Contains 90% or more protein, with most fats, carbs, and lactose removed. It’s a purer and faster-digesting option, ideal for those wanting high protein with minimal extras.
If you're lactose-sensitive or looking for a leaner protein source, whey isolate is the better choice. If you want a more natural, cost-effective option with some added nutrients, whey concentrate works well.
100% Isolate has gone through more filtering taking out majoirty of the lactose and fructose. Yielding it with a much higher protein content. They are perfect for individuals on a very strict macro plan or in a caloric deficit.
Blend proteins will have fructose and lactose, and usually a bit more carbs, and fats. They tend to be creamier and can taste a little bit better. They are also known to cause GI distress.
It is up to you. Protein timing does not necessarily mean as much as getting your total protein content in each day. So having a goal of lets say 220g of protein and ensuring you hit that before you go to bed each night.

Customer Reviews
Good flavor, easy to mix, no clumping
I LOVE the idea of having samples to try before buying a big container of anything, but especially protein powder. The confetti cake was my absolute favorite but honestly they were all great.
Fantastic flavors in this sample pack! I was blown away by the vibrant flavors.
I always have these stashed in my suitcase and carry on bag when traveling
I wanted to try their protein, and this sample was the way and it was great, taste really good and also the macros are good
