The best time to take BCAA supplements is before, during and after exercise. Take them 30 minutes before your workout so that the body has enough time to absorb all of the amino acids required for muscle recovery. During training it’s important that you keep up a high-carbohydrate intake because this will help sustain energy levels while allowing for fat loss without losing strength. However, if you’re active outside of training then try taking BCAAS in between meals or with breakfast but drink plenty of water alongside them as these supplements are quite hydrating (so don’t overdo it!). Lastly, make sure you replenish your leucine stores post-workout; bcaas can be used in conjunction with whey protein depending on what goals you have in mind!
