Understanding Vitamin P and Its Dietary Sources

The term “Vitamin P” is rarely used in modern science but originally referred to a group of plant-based compounds known as flavonoids. While not true vitamins, flavonoids are essential for human health due to their antioxidant, anti-inflammatory, and blood vessel-supporting properties.
What are flavonoids?
Flavonoids are phytonutrients found in a wide variety of fruits, vegetables, herbs, teas, and even red wine. There are over 6,000 types, grouped into several subclasses: flavonols, flavones, flavanones, anthocyanins, isoflavones, and flavanols.
Health Benefits of Flavonoids (Vitamin P)
