![]() "As leucine prolongs muscle protein synthesis after training and after meals, it can be effective for people to consume leucine 90 minutes after breakfast or lunch also, particularly where muscle gain is the goal. "For optimal muscle gain, we would recommend a product with 5-8 grams of leucine throughout your workout with 1-1.5 litres of water," says Mitchell. The Best Whey Protein Powders To Buy in 2023.The study suggests that BCAA supplementation can help decrease muscle soreness after a particularly strenuous workout, with the study comparing a placebo group against a supplemented group, with the latter showing "a reduction muscle soreness". Research published in the Journal of International Society of Sports Nutrition found that consuming the correct amount of BCAAs can help iron out delayed onset muscle soreness. "Helping to reduce excess fat, and helping to normalise visceral fat, which is a marker of metabolic problems." "Supplementation of the BCAA leucine, especially in combination with glutamine, has been shown to help overweight subjects on a hypocaloric diet," says Mitchell. When it comes to fat-burning, BCAAs and leucine intake could help with weight loss. In the study, participants supplemented with BCAAs showed signs of improved mental focus during exercise. Of course, there are several factors in any workout that can contribute to this - intensity, duration and fitness levels, to name three - but BCAAs help restore levels of tryptophan in your brain, a chemical that converts to serotonin and causes fatigue during exercise. Research suggests BCCAs can fight the rate at which you tire from exercise. In fact, any animal-based protein will contain leucine, isoleucine, and valine. "Real food should always be the priority and getting your diet right should be fundamental before looking to supplementation." One cup of cottage cheese, for example, a scoop of whey protein or 85g of chicken breast will serve up two to three grams of leucine. The Best Vegan Protein Powders To Buy in 2023."Leucine is the one key BCAA required for muscle protein synthesis and prevention of muscle catabolism, inhibiting the breakdown of muscle tissue." "We have long known that BCAAs in general are beneficial during exercise, but we now know that leucine in particular has very specific effects on muscle and that during your workouts the other two only get in the way by competing with leucine for absorption," explains Mitchell. "You can get all the amino acids that you need from real food and you will not suffer if you do not take supplements, including the branched-chain amino acids leucine, isoleucine and valine," says Nick Mitchell, CEO and founder of Ultimate Performance. Within your body, leucine diminishes during exercise, meaning that it must be replaced through your diet to help stimulate further protein synthesis and allow the body to build more muscle. The latter, leucine, is the most important amino acid. Of these nine, however, there's an important trio when it comes to maintaining all-important muscle mass: isoleucine, valine and leucine. The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. The Very Best Protein Powders for Building Muscle. ![]() Not convinced? Well, below, with the help of nutritionists, sports scientists and the latest research into supplements, are all the benefits of BCAAs, plus a few links to some of our top recommended products. ![]() The study found that BCAA supplementation reduced delayed onset muscle soreness (DOMS) following exercise, so if you want to be able to use your arms after doing pull-ups or you want to avoid being consigned to a chair for days after doing legs then consider BCAAs. Well, if this study, published in the International Journal for Vitamin and Nutrition Research, is anything to go by then the answer is a resounding yes. With growing popularity in the weights room - enough to rival that of whey protein, we'll wager - branched-chain amino acids (BCAAs) have earned themselves a spot on any serious sportsperson's supplement shelf.īut what actually are BCCAs? What are the benefits? Are there any side effects and, most importantly, does the average gym-goer truly need them?
