Overview

• A meta-analysis of 145 randomized controlled trials highlights the potential of flavan-3-ols to lower blood pressure and improve vascular health.
• Common sources of flavan-3-ols include tea, dark chocolate, apples, and grapes, which can be integrated into daily diets for heart health benefits.
• The study indicates that flavan-3-ols enhance nitric oxide production, improving blood vessel function independently of blood pressure changes.
• Researchers suggest food-based intake over supplements to avoid risks such as liver issues or interactions with medications.
• Further long-term clinical trials are needed to validate these findings and establish standardized intake guidelines.
