How it
Works.

Whey protein is a complete protein source containing all essential amino acids, including naturally occurring branched-chain amino acids (BCAAs). These amino acids play a key role in muscle protein synthesis, recovery, and maintenance of lean muscle mass.

By combining whey protein concentrate and isolate, PX-Protein delivers a balance of protein quality, taste, and digestibility, making it suitable for consistent daily use rather than occasional supplementation.

Who PX-Protein is for

Gym-goers and strength trainers
Athletes and sports participants
Active adults with higher protein needs
Men and women looking for clean daily protein support

Who it’s not for

Individuals with dairy or lactose intolerance
Those seeking a vegan or plant-based protein
People not requiring additional dietary protein

OLLI PX-Protein whey protein concentrate and isolate

How OLLI PX-Protein stands out

Isolate-only proteins

Many whey isolate products remove beneficial fractions found in concentrate, often at a higher cost.

Low-quality blends

Some protein powders rely on fillers, artificial sweeteners, or unclear protein sources.

OLLI PX-Protein wins

OLLI PX-Protein uses a transparent blend of whey concentrate and isolate, offering quality, taste, digestibility, and value without unnecessary additives. It is positioned as a dependable, everyday protein rather than a niche or over-engineered supplement.

Frequently Asked Questions
PX-Protein

Whey Concentrate is less processed and retains more healthy fats and carbs, while Whey Isolate undergoes further filtration to remove most lactose and fat, resulting in a higher protein percentage. Our PX-Protein combines both to give you the high absorption of isolate with the creamy texture of concentrate.

A typical post-workout shake should provide between 20g and 25g of protein to maximally stimulate muscle repair. Our formula is designed to hit this optimal range, delivering a complete amino acid profile to kickstart recovery immediately after your gym session.

Yes, whey protein is derived from milk, making it suitable for vegetarians (but not vegans). It is considered a complete protein source, providing all 9 essential amino acids required for building and maintaining healthy tissues.

While PX-Protein is excellent for boosting protein intake, it is best used as a supplement to a balanced diet rather than a full meal replacement. However, you can blend it with oats, fruit, and nut butter to create a calorie-rich, nutritious smoothie that acts as a quick breakfast or snack.

No, our PX-Protein is formulated without artificial sweeteners like Aspartame. We use Stevia, a natural plant-based sweetener, to provide a great taste without the added chemicals or extra calories found in many commercial protein powders.

Scientific Evidence

Whey Protein is a popular researched supplement for optimizing strength, power, and recovery. It works through three core mechanisms proven by science:

The Claim: Whey protein supports muscle protein synthesis following resistance
exercise.

The Evidence: A study published in the American Journal of Clinical Nutrition
demonstrated that whey protein stimulates muscle protein synthesis more
effectively than other protein sources. Reference: Tang, J. E., et al. (2009).
https://pubmed.ncbi.nlm.nih.gov/19589961/

The Claim: Adequate protein intake supports maintenance of lean muscle mass.

The Evidence: Research in The Journal of Nutrition shows higher protein
diets support lean body mass in active adults. Reference: Phillips, S. M., et al. (2016).
https://pubmed.ncbi.nlm.nih.gov/26797090/

The Claim: Whey protein supports muscle recovery after exercise.

The Evidence: A review in Nutrients highlights whey protein’s role in
post-exercise muscle repair. Reference: West, D. W. D., et al. (2017).
