Clear filtersAbout Amino Acids supplements in NZ
Amino acid supplements — including BCAAs (branched-chain amino acids) and EAAs (essential amino acids) — support muscle protein synthesis, reduce exercise-induced fatigue, and speed up recovery. BCAAs (leucine, isoleucine, and valine) are the most anabolic amino acids for muscle-building, while EAAs provide all nine amino acids the body cannot produce on its own.
Amino Acids — Frequently Asked Questions
BCAAs are three of the nine essential amino acids (leucine, isoleucine, valine). EAAs include all nine essential amino acids, making them a more complete supplement. If you're already consuming adequate protein, BCAAs may suffice. EAAs are better for fasted training or when total protein intake is low.
If you consume enough total protein from food and protein supplements, additional BCAAs offer limited extra benefit. They are most useful for fasted workouts or as an intra-workout drink to reduce muscle breakdown during long training sessions.
BCAAs and EAAs are typically taken during or around training. Intra-workout (sipped during your session) is a common approach to reduce muscle breakdown and maintain energy.
