Workout recovery support; Muscle protein synthesis support; Electrolyte replenishment
Active adults who want intra- and post-workout amino support, and people with high-volume training seeking convenient muscle recovery nutrition.
Mix 1 scoop in 10–14 fl oz of water and shake well. On training days, take 1 serving during exercise and 1 serving after exercise; on non-training days, take 2 servings spaced out. Taking with adequate water may improve tolerance during workouts.
NSF Contents Certified; Informed Choice certified. Contains artificial and natural flavors; no sugar listed in Supplement Facts.
Leucine signals muscle cells through the mTOR pathway, which may support muscle protein synthesis during and after exercise.
Caution: High-dose amino acids on an empty stomach may cause stomach upset; take with adequate fluids.
Isoleucine is used by muscles for energy and may support glucose uptake into cells during activity.
Caution: May cause digestive discomfort in some people; start with 1 serving to assess tolerance.
Valine serves as an energy source for muscles and may help buffer exercise-related fatigue.
Caution: Excess free-form amino acids may compete with other amino acids for absorption; follow the suggested use.
Glutamine is a major fuel for rapidly dividing cells and may help replenish the body’s glutamine pool after strenuous exercise.
Caution: Large single doses can cause gastrointestinal discomfort; spread intake through the day if sensitive.
Vitamin B6 acts as a coenzyme in amino acid metabolism, which may support effective use of BCAAs.
Caution: High intakes from multiple supplements may add up; check your total daily B6 from all sources.
Leucine activates muscle protein synthesis while isoleucine and valine provide complementary branched-chain amino acids used for energy during training. Glutamine helps replenish amino acid pools after intense exercise. Vitamin B6 supports enzymatic reactions involved in amino acid metabolism, helping the body use these aminos efficiently.
Label Warning: For healthy adults 18 years and older only. Do not use if pregnant or nursing. Consult a licensed, qualified healthcare professional before use, especially if you take medication or have a medical condition. Discontinue use 2 weeks before surgery. Use only as directed.
Who should be cautious: People with kidney concerns or on sodium- or potassium-restricted diets may want to review electrolyte content. Those sensitive to artificial sweeteners may wish to monitor tolerance. If you use medications, discuss with a healthcare provider before use.
