Questions, answeredAnswers to what shoppers ask us most. These same answers power the FAQ schema on this page.

EAAs (essential amino acids) are the full set of 9 amino acids the body can't make itself and must get from food or supplements, while BCAAs (branched-chain amino acids) are just 3 of those 9, often highlighted for muscle protein synthesis. Specific aminos like L-Glutamine or NAC are single amino acids (or derivatives) supplemented on their own for a targeted purpose — glutamine for recovery and gut support, NAC as an antioxidant precursor. LYTES stocks all of these formats so you can choose a broad EAA blend like Perfect Amino or a targeted single amino depending on your goal.

Not necessarily — a good quality protein powder already supplies a full spectrum of amino acids once digested, so amino acid supplements are generally an addition for a specific purpose rather than a replacement. People often add free-form aminos like Perfect Amino for fast absorption around training, or single aminos like glutamine or NAC for recovery and antioxidant support, on top of their regular protein intake. Whether you need both comes down to your training volume, diet and personal goals.

It depends on what you're targeting: Perfect Amino is a broad essential-amino blend suited to general muscle recovery and lean muscle support; L-Glutamine is a single amino popular for training recovery and gut-health support; NAC is typically chosen for general antioxidant support; and TMG (betaine) is often used in performance and hydration-focused stacks. Many people combine one broad EAA product with a targeted single amino based on their specific goals — browse each collection below for the full product range.
