Our Epicatechin Supplement provides 1,000 mg of epicatechin per serving from green tea extract in a simple, vegan-friendly capsule. Epicatechin is a naturally occurring flavanol studied for its role in nitric oxide signaling, vascular function, and pathways involved in exercise performance and muscle function.

Designed for athletes and active adults, this concentrated formula provides a consistent amount of epicatechin without relying on the variable quantities naturally present in foods such as cocoa, tea, apples, and berries.

Each batch is third-party lab tested for quality and purity, with lab results available so you can verify what you’re getting.

Suggested Use: Take according to the serving directions on the product label with a glass of water. Taking epicatechin with a meal may be preferable for individual tolerance.

For a deeper look at amounts studied in humans and how people use epicatechin around training, read our Epicatechin Dosage Guide.
