Why Branched-Chain Amino Acids (BCAA) supplements are hot right now

Best BCAA supplements 2018 addition talks about fermented, pure BCAAs in capsules

BCAA are the ultimate sports nutrition supplements. In fact, if you were to take a single sports nutrition supplement, a good quality BCAA product would be your best bet.

These amino acids are the one starting point for all strength and fitness programs. Taking them can provide across the board benefits for power and endurance, making them uniquely qualified to support strength training, cardiovascular exercise, and everything in between.

There are three main amino acids in BCAA supplements:

  1. L-Leucine
  2. L-Isoleucine
  3. L-Valine

BCAAs are considered to be the most important basic fundamentals for muscle growth and performance.

Few other sports nutrition supplements can match BCAAs versatility. Among other benefits, BCAAs have been shown to

  • Contribute to protein synthesis, for building-block muscle support
  • Energize muscles during intense training sessions for greater power
  • Stimulate anabolic activity and muscle for faster growth via muscles’ mTor pathway
  • Enhance both strength and endurance at the same time
  • Reduce muscle aches after training and improves muscle recovery

Thanks to BCAAs, by taking one supplement you can get a lot of great benefits at one time.

And, because it is so versatile, a good BCAA supplement can help with all sorts of fitness programs: high intensity interval training (HIIT), crosstraining, strength training, fasted traininglong-distance running, bodybuilding and more.

Pretty much any program involving sports, cardiovascular fitness, and strength will benefit from BCAA supplementation.

For all these reasons, BCAAs are one of the most popular and revered sports nutrition supplements of all time.

However, over time we have learned more about the many different types of branched chain amino acids.

They may seem simple, but there are a lot of different variations on the BCAA theme that are available in supplements in 2018.

What are people looking for in a BCAA supplement in 2018?

BCAA – and Just the BCAA

Branched-chain amino acids are great standalone amino acids to put in a supplement. But for some reason, in the past BCAAs were put in crazy complex supplements that include a lot of other ingredients, like pre-workout, fat burners, stimulants – all sorts of different non-BCAA nutrients, usually sports nutrition-oriented.

In 2018, it seems like consumers are more appreciative of the sheer awesomeness of straight-up BCAA supplements. They don’t want their BCAAs mixed together with a lot of other nutrients, which drives down the dosage of each amino acid.

Instead, these days consumers are instead seeking out the purest BCAA they can find. No crazy combinations. Just L leucine, L isoleucine and L valine in the cleanest, highest quality product available.

2:1:1 Ratio

Over BCAAs long history of use as a sports nutrition supplements, it’s three amino acids have been presented in a lot of different ratios.

Science is always evolving on this issue, backspace. There are a lot of opinions and a lot of debate as to which ratio is the best.

The 2018 ratio trend is 2:1:1 BCAA – L leucine to L isoleucine to L valine.

This ratio seems to be emerging because it matches the ratio that is naturally found in human muscle tissue.

Since most people are taking BCAA to improve their muscles, the 2:1:1 ratio seems to check out. Keep in mind though, there are many interpretations of what the ideal BCAA ratio is, and other top-rated BCAA supplements may offer different ratios that are good for different benefits.

Clean label

Consumers are increasingly aware that supplements can sometimes include a lot of pointless junk.

Artificial preservatives, synthetics colors, artificial fillers, harsh stimulants and other ingredients and supplements increase side effect risks and may even be unhealthy.

In addition, gelatin capsules are sometimes of sketchy quality. So as part of overall cleanliness, people will look for a vegan capsule instead.

Our top-rated BCAA supplement shows what a clean BCAA label looks like — no strange synthetics, no GMO, no dumb artificial colors.

In other words, the best BCAA supplements 2018 has to offer seem to be focusing on these “clean label” features a lot more these days.

Easy Absorption

Along those same lines, in 2018 consumers want supplements that are easy to absorb. This can apply to quality ingredients, but also to the way it is supplied.

For example, softgels, capsules, liquids and powders may all be absorbed a little differently. The more you absorb, the greater the chance that your supplement will actually have a chance to work.

In the context of BCAA supplements, in 2018 consumers are looking for quality BCAA sources and advanced delivery forms that are easier to absorb.

As a side benefit, easy to absorb forms are generally believed to be easier on the stomach, with less chance of gas, indigestion, bloating, etc.

Quality BCAA sources

Some modern trends are making people more aware of where their BCAA supplements are sourced.

BCAAs are naturally found in animal products. As a result, a lot of BCAA supplements have animal origins.

A lot of those, especially the cheap crappy supplements, will be getting their BCAA from animal parts and species that are so sketchy you don’t even want to think about it.

A lot of other BCAA supplements are sourced from corn. This doesn’t sound too bad. However, with many of these corn-derived BCAA powders coming from China, you have to worry about toxins, cleanliness, and GMO’s (genetically modified organisms). Just because it’s corn doesn’t mean it’s good.

Much like the clean label priority in 2018, people are now looking for clean sources of BCAAs. The good stuff, which comes with a lot of quality control.

  • One example of a clean source is fermented BCAAs, especially BCAAs that are fermented from sunflower and other non-GMP plant origins

In general, fermented BCAA are considered a clean and premium form in 2018, noted for high bioavailability and easy digestibility.


A lot of BCAA formulations on the market come in powder form. This is good for some people.

Powders mixed in water are generally easy to absorb as supplements. Also, some people like drinking their supplements especially if they find one that tastes good.

However, in 2018 powder BCAA supplements are slipping a little bit. By nature, they are usually way dirtier because they will include artificial colors to make them look good, weird synthetic flavors, and other fillers, flow agents and preservatives that you don’t need in pills and capsules.

In addition, powders aren’t really that convenient, since they have to be mixed and carried around.

In 2018, capsules are emerging as a new favorite form of BCAAs.

There aren’t that many BCAA capsules on the market, at least not yet. But capsules have advantages in that they are super convenient. You can carry them in your pocket and take them with water pre-workout, intra-workout, post-work out, whenever.

In addition, BCAA capsules – at least the really good ones – are (sometimes) way cleaner. They don’t need flavors or colors, and if they are delivered in good-quality capsules, well, that’s about as pure a BCAA experience as you can get.

How Best 5 Rated and Ranked our Best BCAAs

Picking out superior supplements, including in the BCAA category, is easier if you check out our Best 5 How to Buy A Good Supplement Guide.

In addition to the above features and forms, check out the criteria we used in picking our best BCAA supplements:

  1. Health –  The best BCAA supplements are designed to maximize muscle in a natural and healthy way
  2. Quality – The sad reality is that low-quality, cheap BCAA supplements may not work as well
  3. Side effect free – Some BCAA’s with a lot of additives may have side effects; cleaner, quality BCAAs take steps to ensure tolerability
  4. Service – Good return policy, shipping, customer service, etc. goes a long way in making a great BCAA supplement.
  5. Value – “Cheap” can be deceiving. The best value is found in BCAA supplements that your body can absorb and utilize, so you actually get some bang for your buck.

Editor’s Note: The BCAA that is right for you depends on personal preference. Here at Best 5, we recommend pure BCAAs in clean delivery forms with no extras. The reason being, BCAAs are powerful enough to stand on their own and do not need to be mixed in with a lot of other unrelated nutrients or flavors. However, some people prefer flavored powders and prefer some extras in their BCAA supplement. For that reason, we have included a range of options in our 5 Best BCAA Supplements 2018 list below.

We also consider a manufacturer’s reputation, online presence, business rating, and relationship with consumers. These companies stand behind their supplements.
