The Active Ingredient Is: Essential Amino Acids

Essential amino acids are a full set of nine amino acids that your body can’t make on its own and needs to come from the diet or supplements. This blend delivers all nine essential amino acids in a balanced mix to help support normal muscle function and protein turnover. This form combines an amino acid blend with electrolytes and hydration-supporting ingredients to help replenish minerals lost during activity. The inclusion of coconut water powder and adaptogenic ashawagandha supports the broader recovery and hydration context of the formula.

What Do Essential Amino Acids Do?

Essential amino acids play a part in muscle protein synthesis and recovery, helping maintain normal muscle structure after training. They also contribute to hydration and mineral balance through the included electrolytes, which help nerve and muscle function during exercise.

EFSA-guided understanding recognises the role of essential amino acids in keeping protein balance steady and supports their importance in active, healthy people.
