Why BCAAs Are Your New BFFs – Amino Acid Supplements Explained
Everything you need to know about branched-chain amino acids (BCAAs) – the building blocks of protein.
If you’ve taken stock of your training but the results still aren’t coming, you may be training too hard! This might sound counter intuitive however the solution could be branched-chain amino acids. BCAAs maintain a steady flow of protein to your muscles.This helps to reduce muscle loss during exercise and promotes protein synthesis. The usual recommended dose is up to 25g in a workout – it’s better to take the full dose in your hardest workout than spread it out over two or three days. The bottom line is that for hard trainers, BCAAs spare muscle and help recovery. Save them for training days.
What are they?
Amino acids are chains of organic compounds primarily made from the elements carbon, nitrogen, hydrogen and oxygen. More than 500 amino acids are currently known and classified, but only 23 are involved in the process of building proteins. This group is known as the proteinogenic amino acids, which combine into peptide chains (polypeptides) to form the building blocks of a vast array of proteins.
Nine of the 23 proteinogenic group are known as “essential” because, unlike the other 14, your body CANNOT create them from other compounds. This means you need to consume these amino acids – phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine – through your diet. Of these, valine, leucine and isoleucine are grouped together and known as branched-chain amino acids (BCAAs). A “complete” protein source is a food or supplement that contains all nine of the essential amino acids, while an incomplete protein source contains some, but not all, of the nine.
Why are they so important?
BCAAs are the only amino acids not regulated by the gut and liver, which means they head straight to the bloodstream and muscle tissue. There’s evidence that they lower lactate levels, making recovery faster, and increase the release of growth hormone during exercise.
Who should take them?
People who are training extremely hard or in a “fasted” state. Ordinarily, if you train in a fasted state, or don’t eat after exercise, you’ll lose more protein than you rebuild. BCAAs can offset this effect, so are an ideal mid-morning supplement if you’re on some variation of a fasting diet.
How should I take them?
Take them in pill form or add the powdered version to a workout drink at a rate of 5g per hour of training. If you’re on a diet such as the 16/8 fast, take a similar dose mid-morning with green tea.
What about in my protein shake?
Whey protein powder comes in one of four forms: concentrate, isolate, hydrolysate and native. All four types are abundant in BCAAs but double check the label on the tub to be sure you’re not getting short changed. What about other protein powders? Egg and soy proteins are complete protein sources containing all the essential amino acids. Hemp is low on leucine while rice and pea proteins are not complete so you can’t rely on them alone to fulfil your BCAA needs.
Can I just get BCAAs from food?
Most people find it hard to keep food down if they eat before working out, let alone trying to stuff your face during a gym session (hence why supplements are so useful). That said, eating plenty of BCAA-rich foods in your daily diet is definitely a good idea anyway, even if you don’t lift weights. Eggs, beef and turkey are all good places to start, as they’re complete protein sources – so-called because they contain the full range of essential amino acids, including leucine, isoleucine and valine.
Which BCAA should I take?
Most supplement companies will offer a BCAA supplement amongst their stack. We have just released our own JDP Health and Fitness BCAA that sits alongside our Whey Protein supplement to support your training. It is a great tasting supplement that all three of us trainers use to support our training. This is especially important us Jason and I are getting ready for an important photoshoot and Scarlet is prepping to step on stage to compete in a bikini competition.
