What Are BCAAs?

BCAA capsules and in powder form.BCAA stands for Branched-chain Amino Acid. Amino acids are the building blocks of proteins. BCAAs refer to three different amino acids in particular: leucine, isoleucine, and valine (1). These three amino acids aren’t made by the body but must be consumed in your diet. They are essential, meaning you need them because they serve important functions in the body. In fact, BCAAs represent up to 35-40% of the amino acids in your body protein. (2)

Naturally, BCAAs are found in foods such as meats, dairy products (including the incredible egg, a great food for weight loss and your health in general), and legumes (1). In addition to eating BCAA intensive foods, you can take supplements. BCAAs are extracted from food sources or manufactured chemically to produce quality supplements. Through these supplements, you can control your intake of BCAAs more precisely.

But, just because a supplement exists doesn’t mean you should take it. What is so special about BCAAs? These three humble amino acids perform many important functions in the body and offer a range of benefits. Learn all about the advantages of taking BCAAs in the next section.

The Evidence on BCAA Supplements: Are They Worth Taking?

In the world of supplements, it’s hard to tell what’s hype and what’s backed by science. The best BCAA products can be highly effective and beneficial for your health. How exactly? Learn what the research says and what benefits BCAA can offer you. With this knowledge, you’ll be able to make an informed decision about whether or not to add this supplement to your routine:

Medicinal Uses

BCAAs are used for a number of medicinal purposes but are also popular among health and fitness enthusiasts. In medicine, BCAAs are used to treat everything from liver disease to anorexia and mania. BCAAs appear to have a positive effect on message transmission among brain cells, which is why they are used to treat these conditions. (1)

Muscle Building

BCAA for Muscle BuildingWhether you’re hoping to really bulk up or simply convert some of your fat stores to muscle, the best BCAA supplements can help you reach your goal. In fact, it’s one of the top 7 muscle building supplements available here! However, research shows you’ll have to make sure you combine taking BCAAs with resistance exercise. In addition to playing an important role in protein synthesis, the other benefits of BCAA such as reducing muscle soreness and mental fatigue also play an indirect role in helping you build muscle. To build muscle, you have exercise and essentially cause trauma to your muscles (3). So, the more energy you have, both mentally and physically, the more you can exercise and the more muscle you can build!

Regulate Blood Sugar Levels

For people with insulin resistance or diabetes, this benefit is especially interesting. Leucine is the amino acid that may be responsible for this effect. Evidence shows that BCAAs may help stabilize blood glucose levels. Other studies also agree that amino acids play an important role in insulin secretion, which in turn controls blood glucose levels.  In addition to this being good for general health, this effect may also influence weight loss, another benefit of BCAAs discussed below.

Reduce Fatigue

As cited above in the medicinal benefits of the best BCAA powders, these amino acids play an important role in brain functions. Several studies back up the claim that BCAAs can help you to push a bit longer when working out (4, 5, 6). So, if you’re hoping to increase your time exercising and make it all the way through your grueling workout, count on the best BCAA supplements to give you that extra oomph!

Reduce Muscle Soreness

Do you struggle to make it up the stairs after leg day? You’re not alone! Muscle soreness is the natural response to a hard resistance workout.  But, BCAA can help with that too. How? BCAAs may lower the blood levels of enzymes that are involved in muscle damage, improving your recovery. In one study, researchers found that women were more sensitive to the effects of BCAA in reducing muscle soreness than men. However, this could be due to dosage differences when compared to body weight. The bottom line is, recuperating quickly from your soreness will help you bounce back and be ready to workout again. So, say goodbye to completely slacking the day after leg day. The best BCAA powder will help you get back to the gym, at least for a quick and easy cardio workout!

Enhance Weight Loss

Man taking BCAA for weight lossMany of the already mentioned benefits of BCAAs are linked to helping you with weight loss. For example, controlling blood glucose levels may help you with weight maintenance. Reducing muscle soreness will help make sure you’re able to get in a solid workout every day which is essential when working towards weight loss goals. The benefit of reducing fatigue has a similar positive influence on weight loss.

Aside from these benefits, BCAAs may play a more direct role in helping with weight loss. This study shows how participants who ate a diet higher in protein were able to lose more weight (and lost a higher percentage of body fat than lean body mass) than those who ate a diet higher in carbohydrates.

Now that you know what the best BCAA supplements can do for you, it’s time to learn more about the products available on the market.

The Bottom Line

Choose from 16 different flavors that all offer a great source of proteins including BCAAs. The only possible downside is the ratio of leucine to isoleucine and valine isn’t disclosed in the ingredients.

Best Tasting BCAA

BCAA in capsule and powder formWhen you’re trying to chug back your BCAAs, taste matters. So, what’s the best tasting option out there? Capsules are obviously flavorless, so going that route is one way to avoid the whole taste issue altogether. However, otherwise, you’ll have to go by your preferences and other user reviews. Flavorless products like the Bulk Supplement’s BCAA powder are not the best tasting (BCAAs are known for their bitterness), but they are the easiest for you to vary. These flavorless mixes can be chucked into smoothies and milkshakes that feature your favorite fruit or chocolate syrup.

As far as flavored products go, the double chocolate flavor of the whey protein by Optimum Nutrition is among the best tasting BCAA sources. If you want a product more specifically focused on BCAAs, Scivation’s Blue Raspberry and Mango flavors get great reviews and may very well be the best tasting BCAA powders on the market.

Best Time to Take BCAA

As with all supplements, when you take it can play a big role in its effectiveness. However when it comes to BCAAs, the jury’s still out regarding when you should take it. As a general guideline, the best time to take BCAA is just before, during or after your workout. Some studies favor taking the supplement before working out, while other studies show that timing doesn’t make much of a difference.

Best BCAA Ratio

A popular ratio for BCAA supplements is 2:1:1. But, is it the best BCAA ratio? Where did it come from?

One study shows that all three of the amino acids (leucine, isoleucine and valine) are needed to achieve effective outcomes. Just leucine on its own won’t do, although there’s also evidence that this particular amino acid may play a more important role than the other two. Thus, scientists have favored using more leucine than the other two amino acids in their ratios when conducting research studies.

There are many examples of studies that use the 2:1:1 ratio, as it’s the standard ratio favored by researchers. But, what exactly does it mean? The 2:1:1 ratio means that there’s twice as much leucine as there is isoleucine and valine. For example, Xtend by Scivation contains 3500 mg of leucine, but only 1750 mg of isoleucine and 1750 mg of valine, for a total of 7000 mg of BCAAs. Nearly all of the above product recommendations make use of the 2:1:1 ratio.

In conclusion, the best BCAA supplements follow the research and offer a 2:1:1 ratio.

How Much BCAA Should You Take?

This is another important point. How much BCAA do you need? Experts recommend taking between 3 to 5 grams daily. Do keep in mind that you can also get your BCAAs from food sources such as meat, dairy, and legumes. So, don’t get hung up on consuming your BCAAs only through supplements.
