Workout recovery, Muscle support, Electrolyte support
Active adults who train regularly and want convenient intra- and post-workout amino acids, and people seeking a zero-sugar option to support workout recovery needs.
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 throughout the day. For best tolerance, sip with adequate water; amino acid powders are often comfortable taken around workouts.
Zero sugar. Contains artificial flavors and colors. No allergen disclosures listed.
Leucine signals muscle protein synthesis via activation of the mTOR pathway and serves as a building block for new muscle proteins.
Caution: High doses of isolated amino acids may cause digestive upset in some people; start with a single serving to assess tolerance.
Isoleucine supports muscle protein synthesis and can be used by muscles as an energy source during exercise.
Caution: Large amounts of BCAAs may interact with some medications or compete with other amino acids; space from protein-rich meals if sensitive.
Valine contributes to muscle protein synthesis and serves as a substrate for energy production during activity.
Caution: Excessive intake may cause stomach discomfort; follow serving directions to avoid unnecessary excess.
Glutamine is a conditionally essential amino acid that supports nitrogen transport and serves as fuel for rapidly dividing cells.
Caution: May affect tolerance in those with sensitive stomachs; take with adequate fluid to reduce GI discomfort.
Vitamin B6 acts as a cofactor in amino acid metabolism, supporting the conversion and utilization of amino acids.
Caution: Very high intakes of B6 over time may cause nerve-related symptoms; this formula provides a moderate amount per serving.
Leucine, isoleucine, and valine work together as branched-chain amino acids to drive muscle protein synthesis while also providing exercise fuel. Glutamine complements the BCAAs by supporting nitrogen balance and recovery needs. Vitamin B6 aids amino acid metabolism, helping the body utilize these amino acids efficiently.
Label Warning: For healthy adults 18 years or older. Do not use if pregnant or nursing. Consult a licensed healthcare professional before use, especially if you take medication or have a medical condition. Stop use 2 weeks before surgery. Use only as directed.
Who should be cautious: People with high blood pressure, kidney issues, or on sodium-restricted diets may want to review the electrolyte content. Those sensitive to artificial sweeteners may prefer caution. If combining with medications, discuss with a healthcare provider before use.
Storage: Store in a cool, dry place.
