Epicatechin – Myostatin Modulator and Performance Enhancer

What Is Epicatechin?

Epicatechin is a powerful flavanol found naturally in cocoa, green tea, and berries. Known for its antioxidant and anti-inflammatory properties, epicatechin is gaining attention for its potential impact on muscle physiology, nitric oxide production, and metabolic function. Preliminary studies suggest that it may positively influence myostatin inhibition, enhance protein synthesis, and support vascular health.

Muscle Growth, Performance, & Recovery

One of epicatechin's most promising effects lies in its interaction with myostatin—a protein that restricts muscle growth. Early research indicates that epicatechin may help inhibit myostatin signaling, potentially unlocking greater muscle development. This makes it of interest to bodybuilders, athletes, and those undergoing physical rehabilitation.

Additional studies have linked epicatechin to enhanced muscle protein synthesis and improved muscle recovery. It also shows potential to affect muscle contractility and mitochondrial function, further supporting endurance and muscle adaptation during resistance training.

Nitric Oxide Production

Epicatechin may improve nitric oxide (NO) bioavailability by stimulating endothelial nitric oxide synthase (eNOS). This helps promote vasodilation, leading to better blood flow, enhanced oxygen delivery, and improved cognitive and cardiovascular function. These benefits can be especially useful for athletes or individuals with compromised circulation.

Antioxidant Activity

As an antioxidant, epicatechin helps neutralize harmful reactive oxygen species (ROS) and supports the body’s internal defense systems. It has also been shown to increase levels of natural antioxidants such as superoxide dismutase (SOD) and catalase. These actions contribute to reduced oxidative stress, supporting cellular health and longevity.

Key Benefits

• Supports muscle growth via potential myostatin modulation
