One study published in the journal Amino Acids , for example, found that well-trained cyclists who supplemented with 12 grams of BCAAs per day for 10 weeks increased cycling power and improved time trial performances.
Though we know BCAAs can benefit weight lifters and cardio junkies alike, research on the ideal time to take them is still a bit mixed. For a long time, research on amino acid ingestion focused heavily on timing. While there is a clear window of time post-workout when your body better uses carbs to replace muscle glycogen and recover, the muscle protein synthesis process lasts longer.
This means we may not need amino acids as urgently. One study published in Frontiers in Physiology found that supplementing with 5. However, a recent Journal of the International Society of Sports Nutrition suggests consuming BCAAs has similar effects on performance and muscle mass when taken either pre- or post-workout. However, since BCAAs take about 30 minutes to really hit your bloodstream, take a dose at least six grams half an hour before getting sweaty to really get the most out of their potential fatigue-busting benefits.
During exercise, it increases to g per hour. Ordering from overseas can be riskier as not all countries have regulations for supplements, including the USA. If you've made it this far, you now know more than most people about BCAAs an probably have a grasp on how you can implement them into your training and nutrition strategy. To help wrap things up, this is everything you need to know. Easier fat-loss, more energy and increased muscle gain are all benefits BCAA supplementation can make, but a well-rounded diet should be able to cover most of your muscle-building needs , without you having to turn to BCAA powder or BCAA tablets.
That's if you're not vegan or vegetarian, because many high-protein foods — think chicken, eggs and wild salmon — packing plenty of BCAA alongside the protein count. Add these to your basket and stock up on strength. It's best to take BCAA supplements before a workout, up to 15 minutes pre-workout or taken during your workout to prevent further fatigue. Broadly speaking, there's very little to be worried about when it comes to BCAA supplementation.
Follow the instructions and be sure to take them at the right time. They won't make you overweight, either — a regular 10g serving of BCAAs contains approximately 40kcal. Vegans and vegetarians are encouraged to check the label before consumption. Like this article? Sign up to our newsletter to get more articles like this delivered straight to your inbox.

In the study, young men took 10 grams of BCAAs before a strengthening exercise for their nondominant arm.
They experienced less muscle soreness after exercise and lower blood markers of muscle damage than those who took the BCAAs after the arm exercise The only other study available for comparison is one that gave athletic men 25 grams of whey protein isolate supplying 5.
In this study, both groups had the same improvements in body composition and strength BCAA levels in your blood peak 30 minutes after consuming the supplement, but studies have yet to determine the optimal time to take it Despite the long-held theory that you have about 45—60 minutes after exercise to get maximum muscle building benefits from consuming protein, newer research suggests this window of time may be as wide as 5 hours after exercise 11 , Taking BCAAs during workouts has been studied a little in endurance training, such as distance running and cycling.
Additionally, research in cyclists has failed to show an improvement in physical performance from taking BCAAs during endurance exercise, though the supplements may help reduce mental fatigue Research to clarify the optimal time to take BCAAs is limited. It may not make much difference whether BCAA supplements are taken before or after exercise, and you may not need to time them precisely to support muscle building.
In a recent review of studies, scientists found that three factors seemed to be important for limiting exercise-related muscle damage through BCAA supplements. First, you may need to consume a daily dose of at least 91 mg per pound mg per kg of body weight. For example, if you weigh pounds 75 kg , you would need to take a dose of at least 15 grams 15, mg of BCAAs daily. Third, how frequently you take the supplement may be a factor. In other words, splitting your total daily dose into two or more doses, such as before and after exercise, may be beneficial 4.
Lastly, keep in mind that you need more than BCAAs to build muscle protein. There are six other essential amino acids you must consume so your body can make protein.
So, including other sources of protein in your diet is crucial 2. Muscle-protective benefits of BCAA supplements may be more likely if you take 91 mg per pound mg per kg of body weight daily, including on nonexercise days. It may also help to split your daily BCAA supplement intake into two or more doses.
