OVERVIEW
Epicatechin is a flavanol compound naturally present in cocoa, green tea, and berries. It has been researched for its antioxidant properties and its potential to support various physiological functions. Epicatechin helps neutralize free radicals, which are known to cause oxidative stress, and supports cellular health. It has been shown to influence nitric oxide production, which plays a role in promoting healthy blood flow. Studies suggest that epicatechin may also support glucose metabolism and muscle physiology through mechanisms such as myostatin modulation and protein synthesis enhancement, areas that require further clinical investigation for confirmation of its effects.
-
MUSCLE GROWTH, PERFORMANCE, & RECOVERY
Research has indicated that epicatechin may interact with pathways related to muscle physiology. Myostatin is a protein involved in regulating muscle growth, and some studies suggest that epicatechin may influence myostatin signaling, a pathway associated with muscle development and adaptation.1
Epicatechin is also involved in supporting protein synthesis, which is critical for muscle repair and maintenance. Preliminary research has indicated a potential benefit for those engaging in resistance training or exercise by supporting muscle adaptation and recovery.2 Additionally, epicatechin has been observed to influence skeletal muscle contractility and energy production by interacting with cellular pathways such as calcium release and mitochondrial biogenesis.3 -
NITRIC OXIDE PRODUCTION
Epicatechin has been studied for its role in supporting the body’s production of nitric oxide (NO) through its interaction with endothelial nitric oxide synthase (eNOS). NO is involved in vascular function, contributing to the relaxation of blood vessels and promoting healthy blood flow. Research suggests that this mechanism may support cardiovascular and cognitive function.4
-
ANTIOXIDANT ACTIVITY
Epicatechin demonstrates antioxidant activity through multiple mechanisms. It directly neutralizes reactive oxygen species (ROS) and reactive nitrogen species (RNS), reducing oxidative stress in the body. Additionally, it may enhance the activity of endogenous antioxidant enzymes such as superoxide dismutase (SOD) and catalase, which further supports the body’s defense against oxidative damage.5

What is epicatechin?
Epicatechin is a bioactive compound found in dark chocolate, green tea, and certain fruits like apples, grapes, and berries. It’s been studied in both human and animal models for its beneficial effects on oxidative capacity, blood flow, and skeletal muscle adaptation.Research has shown that epicatechin supplementation may:- Support nitric oxide production
- Maintains a healthy balance of myostatin and follistatin (muscle growth regulators)
- Promote mitochondrial biogenesis (the process of creating new mitochondria to support energy production)
- Encourage muscle protein synthesis (the process of building new muscle proteins for growth and repair)
-
What are the benefits of taking an epicatechin supplement?
InfiniWell Epicatechin is formulated to support various fitness and wellness goals. Some of the most cited effects of epicatechin include:Strength gains and muscle size
Epicatechin helps balance myostatin gene expression, the process by which the body produces myostatin, a protein that limits muscle growth. This may support muscle mass maintenance and development—especially when combined with resistance training.
Endurance and recovery
This supplement supports oxygen uptake, nutrient delivery, and muscle recovery during strenuous exercise by encouraging better blood flow and cellular energy production, helping you bounce back faster between training sessions.
Blood flow and vascularity
Epicatechin promotes healthy circulation and vascularity through nitric oxide pathways (the body's natural process for relaxing blood vessels). This may contribute to improved muscle pump, sustained energy, and overall cardiovascular support during physical activity.
Antioxidant defense
It helps combat exercise-induced oxidative stress by neutralizing free radicals and supporting the body’s natural antioxidant systems, which may protect cells and tissues during intense workouts.
Metabolic support
Epicatechin may help aid insulin sensitivity (how effectively the body responds to insulin) and support efficient energy metabolism, which is important for maintaining stable blood sugar levels, fueling workouts, and supporting body composition goals. -
How does epicatechin support muscle growth?
Epicatechin influences key pathways involved in skeletal muscle development. Specifically, it has been shown to:- Suppress myostatin levels (including relative myostatin mRNA expression)
- Support muscle protein synthesis
- Promote increases in skeletal muscle mass and strength when combined with consistent training
- Encourage aerobic training adaptations through improved oxygen uptake
- Potentially increase mitochondrial biogenesis, helping the body meet energy demands during prolonged activity
