Science Agrees: BCAAs Are Awesome

FO_BCAAsport_WatermelonAs experts in the supplement industry, we are intimately familiar with concerns and questions customers and the paying public may have about products.

Do they work? (To wildly varying degrees, yes – buy the good ones.) Are they safe? (Buy from reputable vendors like Nutrishop, and they couldn’t be safer – we don’t hesitate to yank inferior products off our shelves.) What exactly do they do?

We like to turn to science and study when it comes to answering all of those questions. ln recent years, what’s come to light specifically about one certain supplement is extremely encouraging. Not only do BCAAs stand up as an excellent product for fat loss and muscle gain in non-biased, scientific review, but they routinely make regular customers’ shopping lists each time they visit us. A lot of products will come and go – only the best ones stick around when the hype wears off and results are all that’s left. And at the end of the day, BCAAs are always left standing.

What makes Branched Chain Amino Acids such an effective supplement? For starters, BCAAs are incredibly versatile.  Typically, supplements can reasonably claim to address one or two goals – strength, muscle mass, fat loss, or athletic performance. BCAAs can help with all of them. 

A randomized, double-blind study, published in the Journal of International Society of Sports Nutrition, was performed to “evaluate the efficacy of consuming a supplement containing branched-chain amino acids (BCAAs) during an eight-week resistance-training program.”  The conclusion:

Ingestion of a supplement containing BCAAs while following an 8-week resistance training program resulted in a greater decrease in percent body fat, an increase in lean mass, and 10-RM strength gains on the bench press and squat vs. ingestion of a whey supplement or a sports drink. In addition, the ingestion of a whey protein supplement resulted in greater lean mass gains than ingestion of a sports drink.

What does that mean? In short: Regular use of BCAAs as a supplement to your diet and training program make you leaner and stronger. Less fat, more muscle, more strength.

Benefits don’t stop there. In 2006, The Journal of Nutrition published a study that found BCAAs to play a role in reducing exercise fatigue – meaning that if you took BCAAs before and/or during your workouts, you could go more intensely, or longer, to get more out of your exercise. The same study found that “Branched-chain amino acids also positively influence the metabolic response of muscle to exercise.”

Translation: BCAAs slow your metabolism’s feast on your muscle tissue when you’re working out.

Even when you’re not training, though, BCAAs have the same effect. So if you’re taking a break, trying out anabolic fasting diets, going on vacation or suffering an injury that keeps you out of the gym, knocking back BCAAs regularly will help slow the muscle catabolism (your body using muscle for energy) or atrophy that would otherwise occur. That phenomenon was proven out in a study published in Nutrition Research in 2012.

It’s not snake oil, folks.

For years, the most-researched and trusted supplements in this industry were whey protein and creatine. Doubters cropped up all over the place at first, but as the scientific method consistently proved them wrong, these products clearly developed staying power. Well, it’s time to add BCAAs to that list. Study after study is showing that amino acids are not only just an emerging powerhouse supplement, but a must-have for all ranges of athletic ability – from elite athletes to first-day beginners.
