Amino Acids

Essential, Conditionally Essential & Specialist Amino Acids

Amino acids are the building blocks of protein and play a role in many physiological processes, from muscle maintenance to neurotransmitter production, energy metabolism and sleep regulation. Our range covers essential and conditionally essential amino acids, including L-carnitine, L-theanine, L-lysine, L-tryptophan, taurine and L-glutamine, available as standalone formulas or in combination blends for specific goals such as recovery, relaxation or cognitive focus. Each amino acid has a distinct role, so this category is organised to help you find the specific compound relevant to your goal rather than browsing generic blends alone. Products are sourced from brands with transparent dosing and manufacturing standards, covering capsule, powder and tablet formats suited to different daily routines.

Food supplements should not replace a varied and balanced diet and a healthy lifestyle.
