Protein & Amino Acids

Muscle doesn’t build itself. Every repair cycle and training adaptation depends on a steady supply of amino acids, the structural units your body uses to construct and maintain protein tissue.

Protein from food gets broken down during digestion, then reassembled into muscle fibres, enzymes, and hormones. Nine of the twenty are classed as essential, meaning your body can’t produce them. Leucine, one of the three branched-chain amino acids, acts as a direct signal for mTOR, the pathway that triggers muscle protein synthesis after training.

Research consistently links adequate protein intake to lean muscle retention and faster post-exercise recovery. Studies indicate that spreading protein across meals, rather than concentrating it at dinner, produces stronger muscle-building responses throughout the day. Whey absorbs quickly post-training. Casein digests slowly overnight. Plant proteins like pea and rice complement each other well when combined.

Athletes and gym-goers are the obvious audience, but this category covers more ground. Older adults managing age-related muscle loss, busy professionals skipping meals, and plant-based eaters working around lower protein density all commonly reach for these products.
