INTRA[R3]™ provides a clinically researched 15-gram dose of Cluster Dextrin, a superior form of highly branched cyclic dextrin (HBCD), to support improved performance in the gym, as well as help fuel better recovery and muscle gains.* This innovative patented ingredient is easily and rapidly absorbed, promoting fast gastric emptying while helping to minimize gastrointestinal discomfort (bloating, gas, stomach cramps, etc.) as you train.* Its unique molecular structure also helps ensure minimal impact on blood sugar and insulin levels.* The energy and recovery matrix also features 5 g of pure dextrose for instant impact.* Sipping on INTRA[R3] during your workout will drive energizing carbohydrates to muscles quickly, helping you to sustain longer, more intense workouts.*


INTRA[R3] also includes a powerful 100-milligram dose of pantothenic acid, or vitamin B5, to promote optimal synthesis, conversion, and utilization of carbohydrates.* Research shows that B5 also supports neurotransmitters like acetylcholine (ACh) and serotonin, promoting enhanced mental performance, and is used by the body to help maintain the normal healthy function of the adrenal glands.*


INTRA[R3] provides a full spectrum of all nine essential amino acids (EAAs) to help support energy production, improve recovery, combat muscle breakdown, and enhance muscle protein synthesis.* With a fully disclosed 8 g total of anabolic EAAs, including 6 g of fermented instantized branched-chain amino acids (BCAAs) in the proven 2:1:1 ratio, INTRA[R3] delivers an efficacious dose of plant-based amino acids to support your hard training.* The 100% transparent formula means no hefty doses of inferior amino acids hidden behind proprietary blends.* Research shows that when you take EAAs in combination with carbohydrates within the workout window, net muscle protein synthesis is greater than when consumed post-workout.* Consuming an essential amino-carb combo at this time enhances amino acid delivery and absorption in working muscle—leading to faster muscle growth and less muscle soreness after training.*


PeakO₂ is a potent complex of six adaptogenic mushrooms scientifically shown to help the body adapt to and overcome physical and mental stress when performing intense exercise.* By improving oxygen utilization in the body while decreasing lactate build-up in muscles, PeakO₂ supports increased strength, power, and endurance, helping you train harder for longer.* INTRA[R3] delivers a 1-gram dose designed to build off of your pre-workout and fuel all-out workout performance, from start to finish.*


Betaine has been shown to enhance strength, power, and muscle endurance.* INTRA[R3] features a 1-gram dose to support your workout performance.* By acting as a methyl donor, betaine may enhance creatine availability.* Betaine is also osmoregulatory, helping to regulate water balance and promote cell hydration.*


INTRA[R3] delivers a 1-gram dose of vegan, fermented L-tyrosine. Tyrosine is a precursor to neurotransmitters such as norepinephrine and dopamine, which can become depleted during stressful activities like intense training. Tyrosine works to increase these stress-depleted neurotransmitters, supporting enhanced mental performance for better workouts.*


For a complete intra-workout formula, INTRA[R3] features precise doses of key electrolytes—sodium, potassium, and magnesium—to support hydration and help replenish electrolytes lost during hard training.* This advanced matrix also gives you a 1-gram dose of taurine. Research shows that taurine helps draw fluid into muscle cells and enhances the body’s ability to utilize electrolytes.* The additional 100 mg of Pink Himalayan Sea Salt combine to make this matrix a powerhouse for supporting hydration, increased muscle performance, and improved blood flow.*
