Optimize Athletic Potential: Enhance Recovery and Performance

XR™ was originally formulated by surgeons to aid in surgical recovery based on advances in nutritional sciences. This innovative amino acid blend is designed to target musculoskeletal recovery. Clinically researched ingredients at optimal effective doses, support not only surgical and injury recuperation but also athletic performance. Built upon a solid scientific foundation, incorporating aerospace research, and supported by clinical studies for each ingredient, this unique supplement ensures both safety and efficacy. The XR™ comprehensive approach offers a nutritional strategy designed to optimize and maintain performance while supporting quicker recovery with sports nutrition.

Addressing Athlete Challenges: 

Preserving Muscle Strength and Mass During Recovery

In the face of injury, recovery, or immobilization, XR™ ingredients support preventing muscle and strength loss during periods of inactivity. This can hasten return to sport and functional recovery. (1,2,3,4,5,6)

Stimulating Muscle Growth

XR™ features the innovative MSK Anabolic Complex, specifically formulated to optimize skeletal muscle production. (7,8,25)

Decreasing Metabolic Stress

The ingredients within XR™ work to reduce post-exercise metabolic stress markers; cortisol levels, oxidative stress, and lactate buildup. By addressing these markers, we support and optimize the body's natural recovery mechanisms, promoting improved overall wellness and faster recuperation. (9,10,11)

Easing Delayed Onset Muscle Soreness (DOMS)

Improving athletic performance requires sufficient muscle and tissue recovery. XR™ contains ingredients that have be shown to expedite healing, minimize downtime, support muscle fatigue and reduce duration and magnitude of DOMS*, a symptom of exercise-induced muscle damage that occurs following intense exercise. (12,13)

Minimizing Exercise-Induced Muscle Damage (EIMD)

Intense exercises, especially those involving eccentric muscle contractions, can cause mechanical stress and damage to the muscle's structural components. XR's ingredients have been clinically proven to reduce creatine kinase (CK) breakdown, a marker of exercise-Induced muscle damage (EIMD), compared to a placebo.  (13,14,16)

Optimizing Circulation

Optimal circulation and blood flow are necessary to support intense training and promote tissue healing. XR™'s formulation contains ingredients that have been demonstrated to enhance Nitric Oxide production, leading to  increased blood flow, improved muscle contraction, gas exchange, oxygen kinetics, mitochondrial efficiency and improved muscle contractility. (17,26)

Enhance Athletic Performance

XR™'s comprehensive formulation includes a key combination of amino acids that have been demonstrated to work synergistically to positively impact both aerobic and anaerobic performance parameters. (17,20,27,28,29,30,31)

Faster Return to Functional Activity

XR™ supports a quick return to functional activities by aiding in the preservation of muscle strength and mass during recovery, ultimately expediting rehabilitation and enabling athletes to resume their normal daily and athletic routines swiftly. (3,6,18,19)

Preservation of Muscle Mass During Calorie Deficit

Athletes and active adults often aim to improve or maintain fitness while losing weight through caloric restriction, intermittent fasting, and exercise. However, this can risk lean tissue loss, limiting performance. Research indicates that the BCAA supplements in XR™, when combined with resistance training during a hypocaloric diet, can help maintain lean mass and preserve skeletal muscle performance while reducing fat mass. (21,22,23,24)

Minimize Cognitive Fatigue

The decline in cognitive performance has been shown after intense exercise. XR™'s formulation includes Branched-chain amino acids (BCAA) along with creatine, arginine and L-citrulline which have been shown to alleviate exercise-induced central fatigue and improve cognitive function. (32,33,34,35,36)
