BCAA powders have become a go-to for gym lovers, runners and anyone looking to support their training and recovery. But with all the choice out there on different sport supplements, you might be feeling a little overwhelmed about how to choose which is right for you. Here’s everything you need to know before choosing your perfect scoop.
What is BCAA?
BCAA stands for branched-chain amino acid and it refers to three essential amino acids called valine, leucine and isoleucine.1 Amino acids are molecules that combine to form proteins. Your body needs proteins for a number of reasons, including to give you energy, to make hormones and to build and repair your muscles.2
Of the 20 amino acids that make up the proteins in your body and in the foods that you eat, 11 can be made by your body. Research currently highlights that these are called 'non-essential' since you don’t need to actively do anything to get enough of them.1,3 However, the remaining nine are referred to as ‘essential’ because you need to get them through what you eat – and BCAAs are thought to represent three of these.1,3
What foods contain BCAAs?
The good news is that there are a number of different foods that contain BCAAs and by following a diet that’s quite high in protein, you should be able to get enough to support optimal health.2
You can find BCAAs in food like:4
- meat, poultry and fish
- eggs
- dairy products, such as milk and cheese
- cereals, potatoes and starch
- nuts and seeds
- soy products like tofu and tempeh
- legumes, including beans, lentils and peas
- quinoa
How much BCAA is recommended?
It’s been suggested that the recommended dietary allowance (RDA) for sedentary adults should be:5,6
- 45mg per kg of weight for leucine
- 22.5mg per kg of weight, per day of both isoleucine and valine
Our favourite BCAA powders
If you’re an athlete, a fitness fanatic or even if you just live a very active lifestyle, you might want to consider BCAA supplements, with guidance from a medical professional of course. BCAA supplements may be used by people who want to make sure that they’re getting enough protein to support and nourish their muscles before, during and after exercising so that they can be reassured that their muscles will recover well.7 Let’s take a look at some of the best BCAA powders currently on the market.
USN’s pineapple flavoured BCAA powder offers you a full spectrum drink that contains all nine essential amino acids. This powder’s blend is specially formulated to ensure you receive plenty of hydration, with added coconut water powder and electrolytes. It’s also stimulant-free, so you don’t need to worry about getting the jitters. As well as being suitable for vegetarians and vegans, it’s also available in jellybean flavour for an extra sweet treat.
Gold Standard® BCAA is designed to support intense training sessions, with added electrolytes plus vitamin C and magnesium to help reduce tiredness and fatigue. It also contains zinc, which, alongside the vitamin C, contributes to the normal function of the immune system. The added electrolytes help your body stay hydrated during exercise, as they can be lost through sweat, so replacing them can help support hydration, muscle function and overall performance during and after workouts.
Whether you’re lifting weights, training regularly or just looking to support your workout routine, Myprotein Impact Branched Chain Amino Acids offers a convenient way to top up on leucine, isoleucine and valine. The easy-to-mix powder can be added to water and enjoyed around your workouts to support your active lifestyle and recovery routine.
This is a high-impact amino acid powder that’s packed with 6,500mg of essential amino acids, as well as vitamin B6, taurine, beta-alanine and patented AstraGin™ to make sure you get the most out of your workout. Also suitable for vegetarians and vegans, it’s available in a delicious apple flavour too.
One of our best vegan BCAA supplements, it guarantees 7g of sugar-free BCAAs, with zero carbs or sugar. It also contains L-glutamine, L-citrulline and added magnesium to support electrolyte balance, normal protein synthesis and normal muscle function.
BCAA powder potential benefits
So, why should you consider taking BCAA powder? Well, some of these possible benefits can include:6,8,9
- may give you more energy for longer and less exercise fatigue
- may increase muscle mass and performance
- may prevent muscle wasting
- may reduce muscle soreness
Experts say that you can take your BCAA protein powder before, during or after your workout. Taking it before will help you to enjoy more energy during your chosen activity, which may help you to achieve better performance. It may also help prevent muscle breakdown during your workout.6 Meanwhile, taking BCAA after you’re done may help with muscle recovery and reduced delayed onset muscle soreness (or DOMS).8
BCAA powder side effects
The general consensus is that taking branched-chain amino acid supplements is safe and BCAAs side effects are quite rare.10 There are a few possible side effects linked to BCAA powder use, which may vary based on age, medical conditions, medications and diet. These may include:10,11
- upset stomach (bloating, nausea, vomiting, diarrhoea)
- poor blood sugar control (which may make them unsuitable for people with diabetes)
- interference with mood disorders and mental functioning
The final say
BCAA powders are supplements that contain three essential amino acids – valine, leucine and isoleucine – that may help support muscle health, energy and recovery, perfect for active folks and athletes.1,6,8 These amino acids aren’t made by the body, so you need to get them through diet or supplements. While foods like meat, eggs and dairy have BCAAs, supplements can help ensure you get enough.1,3,4
