Workout recovery support, Hydration and electrolyte support, Muscle protein support
Active adults who train regularly and want convenient intra and post-workout amino acids, or those with higher sweat loss seeking added electrolytes for hydration support.
Mix 1 scoop in 10 to 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. If you experience stomach sensitivity, sip gradually and consider taking with a small snack.
Zero sugar. Contains artificial flavours and colours. Made in the U.K. Product does not list common allergens.
Leucine activates the mTOR pathway in muscle cells, which may signal muscle protein building after exercise.
Caution: May cause stomach upset in some people if taken on an empty stomach; take with water and adjust timing if sensitive.
Isoleucine serves as a branched-chain amino acid that can be used by muscles for energy and may support muscle protein turnover.
Caution: High single doses may cause mild digestive discomfort; space doses if needed.
Valine is a branched-chain amino acid involved in muscle energy use and may help reduce exercise-related muscle breakdown signals.
Caution: Excessive intake may contribute to nausea in sensitive individuals; follow serving guidance.
Glutamine is a conditionally essential amino acid that supports nitrogen transport and may help replenish muscle glutamine levels after exercise.
Caution: Those with sensitive stomachs may prefer to take with food or split servings to reduce discomfort.
Vitamin B6 acts as a cofactor in amino acid metabolism, helping enzymes process and utilise amino acids during and after exercise.
Caution: Do not exceed suggested intake as very high chronic doses of B6 may cause nerve-related symptoms.
Leucine triggers mTOR signalling for muscle building while isoleucine and valine provide BCAA support for energy use and reduced breakdown during training. Glutamine helps restore amino acid pools, and vitamin B6 supports the enzymes that metabolise these amino acids. Sodium and potassium contribute to fluid balance to aid hydration during workouts.
Label Warning: For healthy adults aged 18 and over only. Do not use if pregnant or breastfeeding. Consult a licensed, qualified 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 kidney concerns or on sodium- or potassium-restricted plans may need caution due to electrolytes. Those sensitive to artificial sweeteners or food dyes may wish to assess tolerance. If you take any medications, discuss with a healthcare provider before use.
Storage: Store in a cool, dry place.
