BCAA Side Effects – Are You Risking Your Health?

bcaa nutritional values - side effectsIn the last years, as BCAA’s have become more marketed, produced, and used, there was a lot of buzz around them. 

Supplement companies tried to push this product to the limit as much as they could.

I’ve heard questions like “should I take BCAA supplements”, “what are the benefits of taking BCAA’s”, “are there any BCAA side effects?”

If you want a supplement, you are mainly interested in the benefits that supplement gives you. You don’t want any side effects.

Of course that nowadays, very few people are interested in what side effects some of the supplements can have because they either seek size increase or fat loss with any cost.

Before we see if there are any possible BCAA side effects that are worth mentioning, let’s first analyze BCAA’s:

As you can see in the picture above, a typical BCAA product contains L-leucine, L-isoleucine, L-valine, natural/artificial flavors, citric acid, inulin, lecithin, sucralose, tartaric acid, silicone dioxide.

  • L-leucine – is a branched chain amino acid known as hydrophobic amino acid and it’s an essential amino acid
  • L-isoleucine – branched chain amino acid which we cannot synthesize so we must get it from our diet
  • L-valine – another branched chain amino acid classified as “nonpolar”

Other ingredients

  • Silicone dioxide – food additive that is harmless
  • Citric acid – it is commonly found in powder form and citrus fruits. You might have heard about it when you got some vitamin C because many vitamin C supplements contain citric acid.
  • Lecithin – produced by your body and found in the hearth, kidneys, liver. It is mostly known for its possible aid in memory function and learning (there are a lot of supplements coming out on the market with this compound).
  • Sucralose – just another artificial sweetener that is completely harmless. I have discussed about it, here.
  • Tartaric Acid – just like citric acid, the tartaric acid is found in bananas, plants, grapes, and it’s harmless.
  • Inulin – aka diabetic sugar or neosugar, it’s a polysaccharide that is found in plants like leeks, onion, garlic. It is harmless.

This BCAA product is just a small picture of the whole but you can answer the question if BCAA’s have any side effects just by looking at the ingredients.

Not only that but there are no research studies done on BCAA supplementation that found a side effect that is worth mentioning. If you are not satisfied by this, even if you speak with people that used this supplement for years or you search some forums, there are no reports of someone to have negative effects by using BCAA’s.

I also used them in large amounts when I was a beginner. 

I can tell you that if there is anything wrong with them, it’s only the taste. The taste is awful by the way.

Simply put, you supplement your body with BCAA’s even if you don’t take them in powder form because every time you eat fish, chicken, pork, protein powder, or any type of protein, your body gets them.

Finishing with a joke, the single side effect you might get could be just a thinner wallet.

  1. I had some stomach problems back when I was using BCAA’s but I guess that was because I couldn’t cope with the taste..

    Well put!

  2. I guess that the only side effect of supplementing is the awful taste.
    I was wondering if there are any side effects so thanks for letting us know
