  • Product Overview

    BCAA: The Building Blocks of Protein

    Here’s your essential amino acid supplement, containing an optimal 2:1:1 ratio of leucine, isoleucine, and valine. These can’t be produced by your body so they must come from your diet.

    Our BCAA supplement provides a way to consume these essentials without being time consuming or costly.

    Ranked Grade A by independent tester Labdoor for both quality and value, our BCAA is officially certified as one of the best branched-chain amino acids supplements on the market.

    What are the benefits of BCAA?

    They’re your essential amino acids in one convenient supplement. There are nine essential amino acids, and three branch-chain amino acids, which are leucine, isoleucine, and valine. These are the building blocks of protein, which makes up the structure of new muscle tissue.

    This is important for any fitness goal, whether you’re looking to raise your game with another weekly gym session, or packing a few more kilos on your bar.

    When should you take BCAA?

    We recommend taking 5g 2-4 times a day for best results – enjoying one of our range of fruity flavours, or simply adding the Unflavoured version to your favourite shake.

    These amino acids can be taken throughout the day, or before, during, and after exercise.

    Upgrade your gains: how to maximise results

    BCAAs are branch-chain amino acids and form the building blocks of protein, and must come from your diet. But, to make sure you're getting your daily protein allowance, add Impact Whey Protein  — created with premium, grass-fed whey, it’s packed with an impressive 21g of protein per serving, delivering the protein you need from a high-quality source. To save on time and costs, add an Unflavoured scoop of BCAAs to your whey shake.

Very good!

Very good for recovery and the watermelon flavour is tasty! Only one downside, is it takes a while in a shaker to get the powder to dissolve properly. Great for during workouts and first thing in the morning before breakfast. Will be trying out other flavours for comparison.

prefer the old flavour

I love these BCAA powders and since i have started using them, I have definitely recovered quicker from my running sessions. I just wish you hadn't changed the flavour from the raspberry lemonade. This is no where near as nice and just reminds me of the awful blue slush puppie drinks you get at the cinema!

Great product

Have tried both the Mango flavour and the tropical and they both taste great. Mango being my favourite. It does have a slight sweetener like aftertaste but you get used to that quite quickly. I use before, during and straight after exercise and have definitely found that I am able to work harder and longer.
Goes Well With:
Water - haven’t tried anything else

Great tasting

Thought I’d try the berry burst flavour of the bcaas have tried unflavoured and it’s foul!! Read reviews on the berry burst and saw a great offer I couldn’t refuse! Mixes absolutely amazing and the taste is supreme!! Best tasting bcaa I’ve had! Only just started Taking pre and post and have definitely felt the difference
Goes Well With:
Creatine and protein


I purchase BCAA’s because I learned women after a certain age stop producing these nutrients. Plus they’re good for recovery. When myprotein introduced bitter lemon and strawberry and lime I was sceptical. After reading the reviews I thought ok I’ll buy small bags so if I don’t like it I’ve not wasted much. I’m sooooooo pleased with the choice. NOT sickly sweet at all. Will definitely be getting big bags next time.
Goes Well With:
Water and exercise

Highly Recommend

My order of BCAA didnt arrive before my previous one ran out so i had a few days where i didnt have any and i definitely felt the difference when training. We got the Mango Peach flavour this time and its amazing, so tasty and doesn't have any powdery taste. Will defs be getting this one again and ordering well before the current one runs out.
Goes Well With:
Cold water and a few ice cubes to help mix

Can't fault it.

I love the Myprotein BCAA powder. Nice taste and mixes well. I drink them before and during my workout. As I am pretty lean the muscle preserving elements of the BCAAs seem to help me keep my weight up.
Goes Well With:
Whey protein and creatine.

Best BCAA taste

The berry blast is the best tasting BCAA I’ve had to date


Tropical and Bitter Lemon taste the best, great when mixed in a shaker. A decent product that I keep coming back for!
Goes Well With:
Cold water mixed in a shaker

Worth The Buy

I ordered the MyProtein BCAA pouch Unflavoured of 500g one month ago. Overall, due to it’s flaws, I wasn’t 100% satisfied. However there is advantages to this supplement therefore I believe it overpowers the flaws thus making it worth using. I bought the unflavoured BCAA as it has no additives or artificial sweeteners including Sucralose which is included in all the flavours. I believe Sucralose can have bad effects on the body over time therefore I used the unflavoured one. To start, the flavour is absolutely gut-wrenching. I found it was a sour, chemically taste. I first tried it with 20g of Impact Whey Protein mixed in Semi-Skimmed milk. However I couldn’t continue the mix as the taste was too bad. I changed the mix to 20g Whey with 10g BCAA mixed with strawberries, bananas, goji berries and milk. This taste was beautiful. The natural fruit sugars completely masked the chemical taste and overall made a great smoothie. I recommend using that mix if you have the unflavoured BCAA. The texture is a very light almost icing sugar-like powder. I would say I will get about 6 months out of 500g, therefore it is a great price for the amount. I have seen results with the product, yet not outstanding. However I do believe my muscle cells have repaired after training more efficiently while using the supplement as I rarely am supremely stiff in the morning. As far as body image I have only seen a small improvement. To conclude I recommend using this product if you work out or play sport nearly every day, to help rebuild your muscles in the short time you have to recover between sessions. I believe it is worth the price and could help you achieve your sporting goals.

Banana, Strawberries (x4), 20g Goji Berries, 200ml Semi Skinmed Milk and 20g Impact Whey all blended in a smoothie.
