What is beta-alanine?

Beta-alanine is a nonessential amino acid. That means the body can make it on its own, so there's no need to source it from somewhere else. But some studies suggest that adding a little extra beta-alanine to the system can help reduce muscle fatigue and support exercise performance. The idea here is to help people hit their daily exercise goals. Here's a rundown of how it works and who might benefit.

What does beta-alanine do?

Beta-alanine aids in the production of carnosine, an amino acid that helps directly increase muscular exercise capacity. This might allow for more intense workouts. Beta-alanine is thought to be particularly beneficial for high-intensity activities like sprinting or cycling.

Where does beta-alanine come from?

Beta-alanine is formed in the liver. It can also be consumed through natural food sources like meat and poultry. Supplements may also help boost the amount of beta-alanine in the system.

Can beta-alanine actually help improve performance?

There is some evidence to suggest that beta-alanine can help support athletic performance. Different studies have tested different doses on people. Daily supplementation with four to six grams of beta-alanine for at least two to four weeks has been shown to improve exercise performance. Others have seen up to a 200 percent hike. Still, it's important to note that these statistics may also be influenced by things like diet, exercise and initial carnosine levels.

Is beta-alanine the same as creatine?

No, beta-alanine is not the same as creatina. Both supplements might help support athletic performance, but the goal for beta alanine is to help delay muscle fatigue. Creatine, on the other hand, is believed to help strengthen muscle and increase speed. The two are sometimes taken together to help support both fitness goals.

What are some possible downsides of taking beta-alanine?

Beta-alanine is typically considered safe for healthy individuals. Its main side effect involves something called paresthesia, which is a tingling sensation throughout the body. This "pins and needles" sensation typically goes away within 60 to 90 minutes, and sustained release formulations can help reduce this side effect. It's also more common with doses over 800 milligrams.

How much beta-alanine should someone take?

A study showed that the recommended dosage for beta-alanine is between four and six grams per day for at least four weeks.

Consideraciones clave

Beta-alanine is naturally produced in the body, but people can also consume it through meat, poultry or supplements. It helps produce something called carnosine, which can help people improve their muscle recovery and performance. It can be taken alongside other supplements, like creatine, to help support multiple fitness goals.

Beta-alanine is generally considered safe, but taking it in high doses can cause a "pins and needles" sensation throughout the body. Exercise enthusiasts should talk to a health care provider before starting any supplement. That way, they can get information about how it works and whether it's right for them.
