  • 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 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. To save on time and costs, add your BCAA powder to an Impact Whey Protein shake – 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.

Excellent Flavour

What an awesome mix this is, I have tried BCAA powder from a few places but this tops them all. Awesome flavours too

Best product

Best product and very cheap I think from my protein all products are good

Good - but wrong flavour

I’ve ordered BCAAs before and I’ve had no problem, the berry blast flavour is awesome and you can drink it like juice. Accidentally ordered the unflavoured version this time, which is nowhere near as nice, but adding some squash in seems to help. Found it just as useful, does exactly what it should do.
Goes Well With:
Robinson’s squash.


No problems taking on its own or mixing with smoothie
Goes Well With:
Got the unflavoured mixes well with breakfast etc

Peach & Mango BCAA

I purchased this flavour a couple months ago, and was so happy with the taste I loved it. If I had written a review then it would have been 5 stars, however the second batch tastes like the formula has changed. Now Peach & Mango tastes cheap/ flat and has a soapy taste to it. I am really surprised by this as it used to taste so nice. I will be going elsewhere for my BCAA's in future as it seems all other flavours have a soapy taste to them now according to other reviews. Why change something that was already very good.

Don't get unflavoured

I've tried 4 different options now, Unflavoured, Lemon/Lime, Tropical, and Orange. Unflavoured is one of the worst things I've tasted, nothing seems to be able to fully mask the flavour (even tried a ridiculous amount of FlavDrops). Lemon/Lime (seems to no longer be available) is OK, doesn't really taste like lemon or lime. Closer to maybe the flavour (and colour) of mountain dew, but somehow sweeter. Tropical is the best of the bunch, for once a flavoured MP product that isn't too sweet! This gets a 5/5 from me Orange is weird, it's has a slight taste of a real orange yet it's incredibly artifical too, wouldn't recommend. Top tip - Mix with a small amount of protein powder (1/2 scoop, approx 15g) to help prevent the floating bits that refuse to mix. (unsure if this affects the effectiveness of BCAA, but haven't noticed any problems yet)

First tried this with raspberry lemonade and really enjoyed the flavour. Have tried to order the same flavour several times but it’s never on the list. Product itself is pretty effective. More raspberry lemonade please.

Berry blast bcaa powder

I ordered the Berry blast flavour recently. I read the other review saying it tasted a bit like soap but it was the only flavour they had in stock. They weren't wrong. It tastes completely like soap mixed with cheap council estate squash. Absolutely disgusting. I've had lemon n lime before which was nice. As was the raspberry.

Tastes Great

I ordered my first lot in raspberry lemonade and absolutely loved the taste. I usually have to pre mix it in my shaker I use 2 scoops and drink throughout the duration of my workout. I have noticed since using this stuff I do not get DOM'S as much. However it is a pain to keep mixing it in my shaker before the gym but the taste of the stuff makes up for it. Was a bit disappointed I only bought a 250g as can't seem to find that flavour on the list now and love it and 250g wont last forever. I have ordered another a flavour to try but not opened that as yet.
Goes Well With:

Very good but gritty

The product in itself is great and really helps with recovery. However I've found it doesn't mix very well... At all. Whilst I mix it with hurricane xs it stays very gritty, tried it with juice and was awful. It mixes but doesn't dissolve to make it smooth.
Goes Well With:
Not a lot
