What Is Zeaxanthin

Zeaxanthin is a carotenoid closely related to Lutein, and the two are almost always discussed together. Zeaxanthin is concentrated in the very centre of the macula, an area called the fovea, which is responsible for our sharpest, most detailed vision. Like Lutein, it helps filter blue light and protects eye cells from oxidative stress. It's found naturally in orange and yellow foods such as corn, orange peppers and egg yolks, and in smaller amounts in leafy greens. Because the body can't make it, zeaxanthin must come from the diet or supplements, and it's a common ingredient in eye-health and 50+ formulas.

Key Benefits

• Concentrates in the fovea, the centre of sharp vision
• Helps filter blue light from screens and sunlight
• Provides antioxidant protection for eye cells
• Works together with Lutein for complete macular support
• Relevant for adults over 50 focused on eye health
• Supports visual comfort for people who spend long hours on screens

Who Needs It

Adults over 50, heavy screen users, and anyone with a low intake of colourful vegetables and eggs. It's typically taken alongside Lutein rather than on its own. In Nigeria, choosing yellow over white maize is one easy food swap that raises zeaxanthin intake.

Zeaxanthin in Nigerian Foods

Yellow maize (agbado or masara) is one of the best Nigerian sources of zeaxanthin, whether roasted, boiled or in pap. White maize, which is also widely eaten, contains very little, because the yellow colour itself comes from carotenoids like zeaxanthin. Egg yolks and leafy greens add more. Choosing yellow maize when you have the option is a simple swap for eye health.

Recommended Dosage / Form

Typically included with Lutein in eye-health or 50+ multivitamin formulas, taken once daily with a meal containing fat for better absorption.

Science / Research Note

Zeaxanthin's concentration in the fovea and its blue-light-filtering role are well documented in eye-health research, where it is usually studied together with Lutein.
