Best BCAA supplements: A complete buying guide

All you need to know before buying a great BCAA supplement

Branched chain amino acid (BCAA) supplements are one of the most popular dietary supplements sold, and there’s plenty of research backing the health claims of these products: From reducing muscle fatigue to building muscle mass, using the best BCAA supplements as part of your fitness regime they can provide a range of benefits. However, understanding what are the best BCAA supplements for you to take can be rather difficult, as there is a huge range of products all claiming to be best. Here’s everything you need to know for finding the right BBCA supplements for your needs.

What are BCAA supplements?

BCAAs are a health supplement that features a range of organic compounds known as amino acids, which are very important for the recovery and building of muscle mass. BCAA supplements feature a selection of amino acids, such as valine, leucine, and isoleucine, that don’t have to be processed by the liver and gut, meaning they go straight to the blood and muscle cells to help with recovery and building. BCAA supplements have been developed for use in the fitness industry, as they don’t have to be digested like food, making them suitable for consumption before workouts.

Why should you buy a good BCAA supplement?

The best BCAA supplements allow a range of benefits for people that frequently exercise, especially bodybuilders looking to lose body fat while retaining muscle mass. This is due to BCAAs preventing the body from breaking down muscle mass when dieting, which is a common practice among bodybuilders and anyone looking for a leaner body without losing any muscle size. Additionally, a BCAA supplement can help with muscle building as it stimulates the process of protein synthesis, allowing for faster muscle recovery as the muscles repair at a quicker rate and thus becoming bigger. Further, consuming BCCA supplements before a workout can reduce tiredness, allowing for a more intensive workout.

So, if you are serious about exercising and getting that perfect combination of lean muscle mass and low body fat, BBCA supplements are a fantastic product well worth investing in.

How to choose the right BCAA supplement?

Like most health supplements, there’s a massive selection of different BCAAs to choose, so it’s important to know what to look for to get the perfect one. Here are a few things to consider when looking for the best BCAA supplement you can find:

  • Digestion Speed: The faster the BCAAs can be digested the more effective they are, so whenever looking at a potential product be sure to research their digestion speed. This should be easy enough to find as it is one of the biggest selling points of the product, especially if there is an individual selling it to you. If there’s no information about this, it’s probably best to avoid the brand.
  • Enhanced Products: Some of the best BCAA supplements contain enhancers to provide additional benefits, such as extra energy boost, added electrolytes, and better weight loss. This may be worth getting if it suits your workout habits or any goals you’ve set, such as losing weight more efficiently.
  • Leucine Content: Leucine is one of the main amino acids in BCAAs and the only one that prevents muscle protein breakdown during fasting. So, if your main goal is to lose body fat while maintaining muscle mass, look for BCAAs with the highest amount of leucine.
What is the best kind of BCAA supplement in the UK?

Here are some popular types of BCAA supplements available:

  • BCAA Powder: BCAA supplement powder is a soluble supplement combined with liquid, turning it into a drink, not unlike a protein shake. This is certainly the best BCAA supplement as it has the highest concentration of amino acids. You need a few table spoons for the positive effects of BCAAs to take effect.
  • BCAA Capsules: BCAA supplements in capsule form are just as effective as powders, but the only downside is you will need to take a high number of capsules to get the recommended dose. BCAA capsules also tend to be costlier, so many opt for powder instead.
