BCAA & EAA Amino Acid Supplements
Amino acid supplements give your muscles the building blocks they use during and after training. BCAAs contain three branched-chain amino acids (leucine, isoleucine and valine), while EAAs contain all nine essential amino acids. Many people sip them during long or hot workouts, and some formulas add electrolytes for hydration.

BCAA & EAA Amino Acid Supplements: frequently asked questions
Should I choose BCAA or EAA?
EAA contain all nine essential amino acids, while BCAA contain only three. If you pick one, EAA give more complete support. Our EAA guide explains more.
Do I need BCAA if I already take whey?
Not really. Whey already contains BCAA. Extra amino acids are most useful when training fasted or sipping during long sessions.
Amino tablets or powder: which is better?
Tablets like Amino 2222 are easy to carry and have no taste. Powders mix into water you can sip through your workout, and many come flavoured.
Are amino drinks with electrolytes good for hot weather?
Yes, options like Amino Energy with Electrolytes or BCAA Pro + Electrolytes help replace salts lost in sweat while you train.
BCAA or EAA: which should you choose?
- EAA is the more complete choice, because muscle repair needs all nine essential amino acids. Read our EAA guide.
- BCAA is popular as a low-calorie drink during training; the classic ratio is 2:1:1. See the BCAA guide.
- Powder or tablets: powders mix into a tasty drink; tablets are easy to carry.
- Already taking whey? Whey already contains BCAAs and EAAs, so amino supplements are optional extras rather than a must.
