How it
Works.

Protein-i6 supports recovery by delivering nutrients required immediately after exercise. Protein provides essential amino acids for muscle repair, while carbohydrates help restore glycogen levels. Together, these nutrients support recovery processes that allow the body to adapt to training and maintain performance across sessions.

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

Frequently Asked Questions
Protein-i6

What should I look for in a post-workout shake?

A good post-workout shake should contain high-quality protein, essential amino acids (including BCAAs), carbohydrates, and electrolytes. Protein supports muscle repair and growth, while carbohydrates replenish glycogen stores and electrolytes restore hydration. Shakes like Protein-i6 combine all these nutrients in one, making it convenient to maximize recovery, reduce muscle soreness, and prepare your body for the next workout. Research shows that consuming protein with carbs after exercise optimizes muscle protein synthesis.

How soon after a workout should I take a post-workout shake?

Experts recommend taking a post-workout shake within 30–60 minutes after exercise, a window often called the “anabolic window.” This ensures your muscles receive amino acids, protein, and carbohydrates when they’re most receptive, speeding up recovery and reducing fatigue. Protein-i6 is designed to be quickly absorbed, providing the right nutrients for lean muscle gain and faster recovery immediately after training.

Can a post-workout shake help with muscle growth and recovery?

Yes - post-workout shakes like Protein-i6 provide protein and amino acids that stimulate muscle protein synthesis, repair micro-tears in muscle fibers, and accelerate recovery. Adding carbs helps replenish glycogen, while electrolytes support hydration. Studies show consuming protein post-exercise improves muscle mass, strength, and recovery, making shakes essential for anyone training for strength, endurance, or overall fitness.

What is the best type of protein for a post-workout shake?

High-quality whey protein is widely regarded as ideal for post-workout recovery due to its rapid absorption and high essential amino acid content. Other proteins like casein, soy, or blended plant proteins also work but may digest more slowly. Protein-i6 uses a complete protein blend with fast-absorbing whey and added amino acids, ensuring your muscles get the nutrients they need quickly to maximize repair, growth, and energy replenishment.

Can post-workout shakes help with recovery for women and older adults?

Absolutely, post-workout shakes benefit anyone engaging in resistance training or endurance exercise. Women and older adults especially benefit from protein and amino acids to maintain muscle mass, support bone health, and improve recovery. Protein-i6’s all-in-one formula provides the right nutrients in one convenient shake, making it ideal for both younger athletes and older adults looking to maintain strength, reduce fatigue, and support overall wellness.

Scientific Evidence

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

Whey Protein and Muscle Protein Synthesis

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/

Protein Intake and Lean Muscle Mass

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/

Whey Protein and Recovery

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).
