Amino Acid Supplements

Shop amino acid supplements at Elite Supps. Amino acids are the building blocks of protein, and they do a lot of the heavy lifting behind muscle growth, recovery and performance. Whether you want BCAAs for recovery, EAAs for muscle building, or beta-alanine for endurance, our range has a formula for your goal. Every member of our team is a certified nutritionist, so you can choose with confidence.

What Are Amino Acids?

Amino acids are the molecules your body uses to build and repair protein, including muscle. There are 20 in total, and nine of them are "essential" - your body cannot make them, so they have to come from food or supplements (1). Training breaks down muscle protein; amino acids provide what your body needs to rebuild it stronger.

Shop Amino Acids by Type

  • BCAAs - leucine, isoleucine and valine, for recovery and reduced muscle soreness.
  • EAAs - all nine essential amino acids, the more complete option for muscle protein synthesis.
  • Glutamine - the body's most abundant amino acid, popular for recovery.
  • Beta-Alanine - for muscular endurance during high-intensity training.
  • L-Arginine and intra-workout blends - for pump and in-session support.

BCAAs vs EAAs - Which Do You Need?

BCAAs are three of the nine essential amino acids, and they are strongly linked to recovery and reduced soreness. EAAs include all nine, which makes them the more complete choice for actually building muscle, since muscle protein synthesis needs the full set. A simple rule: EAAs for muscle building, BCAAs if recovery and reduced soreness are your main goal. Many intra-workout formulas combine both.

How to Use Amino Acids

Most people take amino acids before or during training to support performance and recovery, or through the day to top up intake. They work alongside a protein-rich diet rather than replacing it - if you already eat plenty of protein, you are getting amino acids from food too. Follow the label, and if you take medication, are pregnant or breastfeeding, or have a health condition, check with your healthcare professional first.

FAQ

What do amino acids do?

Amino acids are the building blocks of protein. Your body uses them to build and repair muscle, and they support recovery, performance and many normal body functions (1).

BCAAs or EAAs - what's the difference?

BCAAs are three of the nine essential amino acids (great for recovery and soreness). EAAs include all nine, making them the more complete choice for building muscle. Many people use EAAs to build and BCAAs to recover.

When should I take amino acids?

Most people take them before or during training, or through the day to top up. Intra-workout is popular for longer or fasted sessions.

Do I need amino acids if I eat enough protein?

If you already eat plenty of protein, you are getting amino acids from food. Supplements are a convenient, low-calorie way to top up around training - a useful extra, not a must for everyone.
