I wish I could get back the money for all the BCAA tablets, BCAA powder & Leucine powders I’ve gone through over the Years..
I suppose it’s a good thing though, I can look back, learn from it and hopefully get this article across to you too so you don’t make the same mistakes,
So all I want to get across here is that most likely, no scrap that, most definitely – you DON’T need to be spending money on BCAA’s for your ‘Gains’ in the gym.
No matter how much your friends tell you they’re the ‘be-all and end-all’ followed by all the hype from Marketing companies – this Blog will make you see different, so let’s dive straight in.
(This blog goes hand in hand with this article here on everything Protein so if you haven’t read that yet, do that first, as it’s a precursor to this one)
If you’re lost as to what BCAA’s actually are, (if you know this, just skip to the next heading) they’re short for ‘Branched Chain Amino Acids’.
Now amino acids are basically the building blocks of Protein, and there’s 9 essential amino acids that you need to survive & thrive,
Then comes these Branched Chain Amino Acids which are a group of 3 out of the 9 essentials you need.
I won’t dive too much more into this but in a basic nutshell, BCAA’s are made up of;

Leucine is the key player here as it directly stimulates Muscle Protein Synthesis (1) and why I used to knock back plain Leucine powder that tasted horrible. I could go much deeper into this and Yes, I’m bypassing a lot of Sciency stuff as I want you to take away the meat and bones from this article.
So firstly, I’ll be robbing this quote from the blog I linked above on Leucine, this is what we KNOW already;
“To maximise the anabolic response (Muscle Protein Synthesis being maxed) we need 2.5-3g of the branched chain amino acid: Leucine, because anymore isn’t necessary.” (2)
Hence why BCAA’s ARE so popular, the thinking goes, “If I keep topping with a BCAA drink in between workouts and throughout the day – the potential to Build More Muscle goes up.”
But we also know that with:
“Muscle Protein Synthesis ‘dropping’ off after 2-3 hours, it’s probably best to space meals 4-6hours apart. So here, just spread out your daily intake over 3-5 meals.”
Then comes to whole Marketing Side of it all, where companies back up their claims with studies that are highly flawed, again that’s another article in istelf If I was to get into those details, but I’ll still reference some studies below if you want to see them for yourself.
Here’s a few of the proposed Benefits from BCAA supplements;
So it all sounds convincing & let’s be honest, it sounds ‘cool’ to think too that if you drink this coloured drink between workouts, you’ll get better Muscle Gain Results.
Again it’s people falling for the shiny things like I’ve done numerous times over the years.
So it’s not magic fairy dust, no matter how many of the Lads & Ladies you follow drink and promote BCAA’s (Because they’re sponsored athletes. Which means they make money from promoting the stuff.)
If you’re getting ‘in’ enough Protein spaced 4-6 Hours apart, 3-5 times a day – you’re BCAA basis are probably covered. (A high protein diet contains a high content of BCAA’s)
If you’re struggling to get in these sources through food ~ that’s why Whey Protein Powder is so handy. Again, that’ll cover all your BCAA needs as it’s the same thing.
So instead of blowing €20-50 a Month on BCAA’s ~ Whey Protein is a much smarter option.

Not rocket science is it? And that’s what 99% of anyone reading this article will need to know…
Now there is some potential benefits out there with science behind it all – but again, you could STILL, just take some Whey:
BUT – again, as I’ve said above – you could still just take Whey Protein & Save your money.
So a pretty boring article really that could be summed up with, BCAA’s are not worth the money, just use Whey 🙂
And as a little closing tip, you need to justify WHY it’s beneficial to you before you make a decision, and because it’s most likely not – there’s no point in taking it. That can go for a LOT of things in this Health & Fitness World too…
If you’ve any questions on this, I’d love to hear them or if there’s any other topics you want to see covered on this website, don’t be afraid to send me a message here over on Instagram.
If you’re a regular reader here or if this is your first time, thank you for reading this far, hopefully it’s been some help to you 🙂
