Flavonoids are a group of natural plant compounds (polyphenols) that have powerful antioxidant, anti-inflammatory, and immune-boosting properties. They are found in fruits, vegetables, tea, chocolate, and wine and are known for their benefits in heart health, brain function, and disease prevention.
Explanation of Flavonoids’ Role in the Body
Flavonoids help protect cells from oxidative stress, improve circulation, and support overall health and longevity.
Key Functions of Flavonoids
- Powerful Antioxidant Effects
- Reduce Inflammation & Boost Immunity
- Help regulate the immune system to fight infections.
- Reduce chronic inflammation, which is linked to heart disease, arthritis, and diabetes.
- Support Heart Health & Circulation
- Improve blood vessel function, reducing high blood pressure.
- Lower LDL (bad cholesterol) and increase HDL (good cholesterol).
- Enhance Brain Function & Prevent Neurodegenerative Diseases
- Improve memory, focus, and learning by boosting brain circulation.
- Protect neurons, reducing the risk of Alzheimer’s and Parkinson’s disease.
- Aid in Metabolism & Weight Management
- Flavonoids like catechins (found in green tea) help boost metabolism and fat burning.
- May help regulate blood sugar levels, preventing insulin resistance.
