EAA 375g

Efectiv Nutrition EAA is a full-spectrum essential amino acid powder delivering 8g of all nine EAAs per serving, including 6g of branched-chain amino acids in a clinically supported 2:1:1 ratio of leucine, isoleucine and valine. It is designed for intra-workout use, post-training recovery or between-meal amino acid support when a full protein shake is impractical or too heavy.

The formula provides a clinical 3g dose of leucine, the primary amino acid identified in research as the key trigger for mTOR pathway activation and muscle protein synthesis. The remaining EAAs include L-lysine, L-threonine, L-phenylalanine, L-methionine, L-histidine and L-tryptophan, covering every essential amino acid your body cannot produce on its own. Each 12.5g serving also includes potassium citrate and magnesium citrate for mineral support, plus vitamin B12. The 375g tub provides 30 servings across 3 flavours at just 10 calories with zero sugar per serving.

The most common use is sipping during training when a full protein shake would sit heavy on the stomach and slow you down. EAAs provide the building blocks for muscle protein synthesis without the digestion load of whole protein. They also work well between meals to maintain a steady amino acid supply throughout the day, which is especially relevant during higher-volume training phases or when overall protein intake from food is inconsistent. Mix one scoop with 500ml of water and drink throughout your session.

EAAs suit anyone who wants targeted amino acid support around training. They are particularly useful for fasted training, longer sessions over 60 minutes, and people who struggle to eat solid food immediately post-workout. If you are already meeting your protein target consistently through food and shakes, separate EAA supplementation is a nice-to-have rather than essential. For a complete protein source that includes all EAAs naturally alongside additional amino acids, Efectiv Whey Protein Concentrate delivers 23g of whole protein per serving.
