Leucine - why I consume it everyday

Leucine is one of the twenty amino acids we consume through our food. It is labelled essential, which means your body cannot make it; you need to eat it. It is vital because it plays a role in physiological processes. From muscle protein synthesis to energy metabolism, leucine is a key player in cellular functions. So if you have never heard of it, let's find out what it is and what it does.

The Multitude of Benefits

Leucine supplementation has been found to significantly improve muscle strength and volume. It not only enhances their physical capabilities but also reduces inflammation, thereby improving their overall well-being. If you are over 30, you are already losing muscle and need to work to retain it.

Leucine activates a functional translational programme that includes increased protein synthesis capacity and energy metabolism. In simple English, it means it helps your body absorb protein better, which is vital for athletes and fitness enthusiasts.

In a study involving rats, low-dose leucine supplementation led to increased body fat loss. I do not necessarily agree with this direct correlation. However, consuming protein results in higher satiety, allowing you to consume fewer calories, which is one possible reason for weight loss.

Leucine has been shown to positively impact the liver and your autonomous nervous system.
