INTRA[R3] delivers premium performance carbohydrates and vitamin B5 for maximum impact on energy levels while you train and recover better afterward.

CLUSTER DEXTRIN: 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 immediate impact. Sipping on INTRA[R3] during your workout will quickly drive energizing carbohydrates to muscles, helping you sustain longer, more intense workouts.

VITAMIN B5: 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] features a full spectrum of all nine essential amino acids, precisely dosed for hard-hitting muscle support, enhancing energy, strength, recovery, and growth.

ESSENTIAL AMINO ACIDS: INTRA[R3] provides a full spectrum of all nine EAAs to help support energy production, improve recovery, combat muscle breakdown, and enhance muscle protein synthesis. With a fully disclosed 8 g total of 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.



INTRA[R3] delivers a powerful combination of PeakO2, Betaine, and L-Tyrosine designed to extend the effects of your pre-workout and amplify training performance. 

PEAKO₂: 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.

BETAINE ANHYDROUS: Betaine has been shown to enhance strength, power, and muscle endurance. INTRA[R3] features a 1-gram dose to build off your pre-workout and support workout performance. Betaine is also osmoregulatory, helping to regulate water balance and promote cell hydration.

FERMENTED L-TYROSINE: 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.



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 makes this a powerhouse for supporting hydration, increased muscle performance, and improved blood flow.

Take one serving (1 rounded scoop) of lntra[R3]™, mixed with 16-20 fl. oz. of water and sip throughout training.
