Up until relatively recently, BCAAs (or branched-chain amino acids) we’re simply a constituent of protein supplements and whey powder.

Now, however, they’re recognized as valuable supplements in their own right as they increase the rate of protein synthesis, thus helping to promote muscle gain (bulk) and, just as importantly, maintain those gains as you lose weight again (cut), which is why we pressed on with this Ultimate, your very own, Best BCAA UK Top 10 List

The three, key BCAAs are Leucine, Isoleucine and Valine, which have traditionally been consumed in a 2:1:1 ratio, although some brands are moving away from this and developing other ratios.

Depending on your preference, you can have your BCAA drink during your workout or afterwards, perhaps in combination with a protein shake.

Serious comment, if you have your BCAA shake and your protein shake after your work out, mix and drink them separately.  We’ve yet to discover any BCAA product which could be mixed and drunk together with any protein product.

You're welcome to try to prove us wrong, but don’t say we didn’t warn you!

So here is our round-up of the top 7 best BCAAs currently available on the market, plus a bonus pick for vegans or anyone else who wants to avoid dairy protein.

We’ve specifically looked for BCAAs which were available on Amazon, so we could be sure you could get your hands on them regardless of where you live, plus if you spend over £20 or have Amazon Prime, delivery is free.

Top Ten BCAAs UK List

BSN Amino X Review

Nutritional Breakdown

The main reason BSN products tend to appear in “best of” lists so regularly is because they offer great value for money and this is certainly true of BSN Amino X.  When it comes to your choice of BCAAs there’s an extra, possible reason to buy it which is that it’s caffeine-free.

In theory, it’s available in 7 flavours although in reality you’re probably going to find four, maybe five, at most stockists, basically reflecting what most people like.  Regardless of what flavour you choose, you’ll get 10g of blended BCAAs along with the essential amino acids, L-Alanine, Taurine and L-Citrulline.

There are a couple of minor points to consider when looking at this product.  The first is that the scoop is quite wide in comparison with the neck of the tub, so it can be a bit of a pain to get the product out.  If that’s an issue for you, then you can just decant it into another airtight container.

The other is that for some reason this product does seem to shake up very easily to the point where it can actually take the lids of shakers (or so we’ve heard), so we’d suggest giving it a bit of a stir or gentle shake, before you go full-blast.

MusclePharm BCAA 3:1:2 Capsules Review

Nutritional Breakdown

Vegetarians move along, these capsules are made with gelatine.  You may wish to look at the MusclePharm BCAA 3:1:2 powder although we have to say we don’t like it as much.

MusclePharm are, currently, the only company producing BCAAs in the 3:1:2 ratio and according to their literature, they have a patent pending on it.  We’re not lawyers, but we’d assume that this patent related to the way in which they produce the formula rather than the ratio itself, since we’re not at all sure how you would be able to patent that.

In any case, each serving of MusclePharm BCAA 3:1:2 delivers 3 grams of L-Leucine, 2 grams of L-Valine and 1 gram of L-Isoleucine.  The company believes that this delivers optimum performance (although we’re more inclined to think that there’s no ideal product for everyone, which is one reason why we try to provide a range of choices).

A serving is 8 capsules, which, effectively have no flavour.  This may be a reason for choosing them, if you can’t find a powder you like (or can manage to hold your nose and swallow).

Optimum Nutrition (Essential) Amino Energy Review

Nutritional Breakdown

This product is sometimes listed with the “essential” bit in the name and sometimes without.  In either case, it’s theoretically available in an impressive 12 flavours although we wouldn’t count on finding them all in stock.  We’d also say that although it’s literally a matter of taste which one you prefer, some flavours do seem to mix more easily than others.

If you have an issue with mixing your drink, using warm water may help.  Warm, in this case means warm, not hot not cold.  You can always heat it up or cool it down once it’s mixed.

Whatever flavour you buy and however you mix it, you end up with 100mg of caffeine to go along with your 5 g of micronised amino acids, which include 3g of BCAAs as follows: L-Leucine 1g,  L-Isoleucine 0.5g, L-Valine 0.5g, L-Glutamine 1g.  This is presumably why Optimum Nutrition (Essential) Amino Energy is often so highly commended for its beneficial influence on mental focus.

The only downside to this product is the same as with all Optimum Nutrition products, namely they are premium-grade products and priced accordingly, but if you’re seriously committed to training, then this could reasonably be counted as an investment purchase.

Phd Nutrition BCAA Intra+ Review

Nutritional Breakdown

PhD Nutrition is another premium brand and it’s made its name on innovation.  The innovation in this case being the addition of coconut-water powder to its three flavours, which are coconut and lime, coconut and mango and watermelon.

We haven’t tried the watermelon flavour but we can tell you that, in general, coconut water is pretty mild and so we doubt you’d notice the taste unless it was really ladled on.  In fact even the coconut and lime is pretty mild although from what we’ve heard, most people find it perfectly pleasant.

In all honesty, we’re not sure what extra benefit the coconut-water powder brings.  We’re not really buying into it as a source of MCTs and, to be fair, PhD Nutrition isn’t advertising it as such.  As far as BCAAs are concerned, however, the fundamentals are solid: L-Leucine 2540mg,  L-Isoleucine 635mg, L-Valine 635mg, L-Glutamine 1340mg and L-Alanine 375mg.

There is also vitamin C for additional benefits, including a boost to your immune system.

Overall, we like the Phd Nutrition BCAA Intra+ a lot, if only because it has mild flavours and powerful benefits.

USN BCAA+ Power Punch Review

Nutritional Breakdown

USN BCAA+ Power Punch

Last but my no means least, out of our main picks, we have USN BCAA+ Power Punch.  It’s available in four “delicious” flavours.  We’ve yet to find a BCAA product which we’d class as “delicious”, so let’s say “pretty decent” for both flavour and mixability.  One serving will get you a substantial 7g of BCAAs in a 2:1:1: ratio (L-Leucine: L-Isoleucine:L-Valine) along with Glutamine and vitamin B6.  USN BCAA+ Power Punch is a caffeine-free product.  Overall, we’d say this was a solid product offering excellent value for money.

The Protein Works is another brand with an innovative ratio, in this case 4:1:2 (L-Leucine: L-Valine: L-Isoleucine), along with magnesium, calcium and vitamin C.  Much to our annoyance, we’re unable to find detailed values for exactly how much you get of any of these but to be fair, The Protein Works is a well-respected name so we’re prepared to believe you get a decent quantity as well as an effective ratio.

In theory, The Protein Works BCAA Extreme is available in four flavours (or three flavours and unflavoured, whichever way you want to look at it).  In practice, you’re probably only going to find a couple widely available.  Overall, this is another premium product at a premium price, but if you have the budget, The Protein Works’ products are generally worth the money.

Bonus pick Vegavero BCAA Powder Review

Nutritional Breakdown

At this point in time, Vegavero is a bit of an unknown quantity to us, however, if you’re looking for an ethical and/or vegan supplement, which is not only guaranteed free of additives such as Maltodextrin, Magnesium Stearate, Silicon Dioxide and Microcrystalline Cellulose but also made with love for the planet, then this one seems pretty decent.

In terms of the actual BCAAs, one serving gets you 500 mg of Leucine, 245 mg of Isoleucine and 245 mg of Valine.

Best BCAA UK - Overall

In our opinion, any one of these brands would probably be fine for people who just liked to keep fit without being too serious about it.  For these people, your decision is likely to be based on taste and/or price and if you have the budget it might be worth trying some of the premium brands just to see how you felt about the flavours as compared to the more affordable ones.

Those who are serious about training, for example, those who want to compete in bodybuilding, would probably do best with one of the more premium brands, but if these are out of your budget then a product from a good, entry-level brand would be a lot better than nothing.
