In today’s world, more people are turning to natural, plant-based compounds to support their health and for good reason. Many everyday foods contain powerful nutrients that quietly protect the body from damage, boost immunity, and support long-term wellness. One such compound gaining attention in nutrition and scientific research is luteolin.

Found in common herbs, vegetables, and teas, luteolin is a lesser-known flavonoid with impressive antioxidant and anti-inflammatory properties. While it may not be as famous as vitamin C or omega-3s, research suggests it plays a meaningful role in supporting brain health, reducing inflammation, and protecting cells from damage.

What Is Luteolin?
