For endurance athletes, however, the benefits of beta alanine supplementation are less clear. While some research has shown improvements in endurance performance with beta alanine supplementation, other studies have found no effect or even negative effects on performance. Additionally, some researchers suggest that carnosine supplementation may be more effective than beta alanine for improving endurance performance.

Despite the mixed results for endurance athletes, many still choose to take beta-alanine supplements due to its proven benefits for weightlifting and high-intensity exercise. It’s important to note that taking too much beta-alanine can cause tingling sensations (known as paresthesia) and other side effects. As with any supplement, it’s best to consult with a healthcare professional before starting a new regimen.


BCAAs are like a superhero team for your muscles, swooping in to repair and rebuild them after a tough workout. These branched-chain amino acids – leucine, isoleucine, and valine – are essential nutrients that play a key role in muscle protein synthesis. BCAAs have been found to reduce muscle damage, decrease recovery time, and improve endurance performance.

One of the benefits of BCAAs is their ability to reduce muscle soreness. When you exercise intensely, your muscles experience microtears that can lead to inflammation and pain. Research has shown that supplementing with BCAAs before or after exercise can help alleviate this soreness by reducing markers of muscle damage. In addition, BCAAs may also enhance recovery by increasing the rate at which muscle cells rebuild themselves.

The optimal dosage of BCAAs depends on factors such as body weight and activity level. Generally speaking, athletes should aim for a dose between 5-20 grams per day. It’s best to take them before or after exercise when they are most effective at promoting protein synthesis and reducing muscle damage.
