Pro BCAA Banner


Optimum Nutrition PRO BCAA contains the nutritional support necessary to keep you in an anabolic state. As the name suggests, PRO BCAA contains BCAA’s, Leucine, Isoleucine and valine in a scientifically proven 2:1:1 ratio.

Intake of the BCAA’s immediately following weight training can “switch on” protein synthesis to initiate the recovery phase and build muscle. Just follow up that serve with some quality protein food or an optimum nutrition whey protein shake in order to provide the entire essential amino acid spectrum. Optimum Nutrition PRO BCAA is also effective for endurance athletes as it helps to prevent muscle catabolism and is a muscle energy source.


This product provides further anti-catabolic support with the addition of L-Glutamine. Glutamine is depleted during physical stressors, like intense physical activity and needs to be replaced for optimal recovery. Each serve of Optimum Nutrition PRO BCAA delivers 8 grams of BCAA’s and 5 grams of Glutamine, making this the perfect product to create some balance on the fine line between catabolism and anabolism.


We highly recommend the Optimum Nutrition PRO BCAA Fruit Punch flavour. It goes down a treat on ice after a punishing gym session!


Pro BCAA powder and BCAA 5000Pro BCAA vs BCAA 5000

Both of these powdered formulations deliver quality branched chain amino acids in scientifically proven 2:1:1 ratio. However, Pro BCAA delivers 8 grams of BCAAs per serve, while BCAA 5000 contains 5 grams per serve. Though a 5 gram BCAA dosage will be fine for most people, anyone training with a particularly high intensity or duration, or who is over 100kg in lean body mass, will need a higher dosage.


While BCAA 5000 does not contain any other active ingredients, Pro BCAA delivers 5 grams of L-Glutamine and a Phytoblend. The Phytoblend contains Grape Seed Extract, Red Wine Grape Extract and Citrus Bioflavonoids. These natural extracts offer significant antioxidant and anti-inflammatory benefits, which may enhance recovery from exercise, particularly after aerobic activity.


L-Glutamine enhances glycogeni accumulation after exercise, thus supporting recovery. In addition, it may reduce delyayed onset muscle soreness and increase peak torque. Though BCAA 5000 is a quality 2:1:1 branched chain amino acid product, Pro BCAA offers greater recovery advantages and a significantly higher BCAA dosage.


How to Use Optimum Nutrition PRO BCAA

Mix 2 scoops with 300-350ml of cold water and consume before, during or after strength training. Use before and after endurance sports to spare muscle tissue (prevent muscle breakdown).
