“When supplementing with beta-alanine, it takes about three weeks for carnosine to be elevated.

“Ultimately, beta-alanine’s role is to enhance muscle carnosine levels,” says Smith-Ryan. With more beta-alanine in your system on a consistent basis, you can increase carnosine levels in muscle cells. The key to improving buffering abilities is carnosine, and beta-alanine is the rate-limiting component to how much carnosine you can produce. The Carnosine Connectionīeta-alanine is a nonessential amino acid, meaning your body makes it naturally.

Even though beta-alanine might be an ingredient in your preworkout formula, you’re probably not getting an effective dose to take full advantage of its ability to boost training, improve recovery and reduce fatigue. So it’s not that people aren’t using it, theorizes Smith-Ryan, but more likely they aren’t taking enough of it. In fact, there are a number of products already on the market that contain beta-alanine as an active ingredient. Dozens of studies have proved its efficacy. The benefit of beta-alanine is not uncharted territory. Muscle cells can buffer acidic compounds naturally however, supplements like beta-alanine can help increase buffering potential. “This allows our muscles to continue to function and maintain intensity, as well as helps us recover more quickly.” Without buffering, our workouts would be pretty short (and painful). “Buffering is our ability to remove byproducts, such as hydrogen ions and lactate, during and after exercise,” says Abbie Smith-Ryan, Ph.D., CSCS*D, FISSN, assistant professor at the University of North Carolina, Chapel Hill. In order to continue training through this onslaught, your body turns to buffering. Your performance quickly worsens as you experience that deep burning sensation and can barely squeeze out another rep. This disrupts the pH balance in the cells and contributes to fatigue during and after a workout.

But your muscles know how to deal with this sensation, and with proper supplementation they can reduce it even more.ĭuring exercise, your muscles generate force and heat. That burning sensation is often dismissed as lactic acid buildup, but it’s actually the accumulation of acidic compounds, including lactate, that cause your muscle fibers to cease contracting. You’re mid-set when your muscles feel like they’ve caught on fire.
