Optimum Nutrition Amino Acids & Bcaa Supplements

Amino acids and BCAA supplements are formulated to support muscle growth, repair, and recovery. BCAAs (branched-chain amino acids) include leucine, isoleucine, and valine – essential nutrients that your body can’t produce on its own and must be obtained through diet or supplementation.

BCAAs are a specific group of three essential amino acids that are especially beneficial for muscle recovery and reducing fatigue. Other amino acids, like glutamine or arginine, support broader functions such as immune health, endurance, or nitric oxide production. Many amino acid drinks combine BCAAs with other key aminos for comprehensive support.

BCAA supplements are typically taken before, during, or after a workout to support performance and recovery. Intra-workout BCAA drinks help reduce muscle breakdown and support endurance, especially during intense or prolonged training.

Not at all. While bodybuilders benefit from BCAA use, these supplements are suitable for anyone with an active lifestyle, including runners, cyclists, gym-goers, and people doing HIIT or resistance training. They're also popular with those looking to maintain muscle while losing weight.

Most amino acid and BCAA supplements are sugar-free or low in carbs, making them a clean option for those watching their calorie intake. They're a great alternative to sugary energy drinks or carb-heavy recovery shakes.

Yes! BCAAs pair well with pre-workouts, creatine, and protein powders. Many athletes stack their supplements to support strength, recovery, and performance, depending on their fitness goals.

It depends on your preference and routine. Capsules offer quick, no-mix convenience—great before training. Powders are ideal for sipping during workouts and often come in refreshing flavours. Sprint Fit stocks both forms to suit your needs.
