USN Amino Acids

Discover USN Amino Acids

Explore our range of amino acids from USN, with options to fit your training goals and the way you move and lift day to day. Whether you’re pushing through heavy sessions or just staying consistent, there’s a format and flavour to suit how you like to train.

USN amino acid powders are easy to mix with water and drink whenever it suits you, so you can slot them into your day in a way that feels natural.

BCAA & EAA blends

Many USN options bring together BCAAs (branched chain amino acids) and EAAs (essential amino acids) in one simple mix. These blends are a good fit if you want an all‑in‑one amino drink rather than juggling separate products.

You’ll find flavours designed to keep your bottle interesting, like the bold taste of BCAA +EAA Blue Raspberry 400g or the crisp BCAA +EAA Apple 400g. They’re made to mix smoothly with water, ready to enjoy whenever you like.

Versatile essential amino formulas

USN’s essential amino formulas offer flexibility and suit a wide range of training styles, from cardio sessions to gym classes and weight training.

Drinks like Nine Aminos Pineapple 330g or Nine Aminos Jelly Bean 330g are designed to be easy to drink, with refreshing and fun flavours that help you keep your water bottle close to hand. You can use them on their own or alongside your usual sports nutrition, depending on your preferences.
