Description
"Zeaxanthin" is a carotenoid pigment found in colorful fruits, vegetables, and the macula of the human retina. Exposure to harmful blue light increases oxidative stress, but zeaxanthin helps shield ocular tissues from damage. It supports macular integrity, visual sharpness, and the aging process of the eyes. Early retinal development also depends on adequate levels of this carotenoid. A consistent intake of zeaxanthin-rich foods helps maintain long-term vision health, reinforcing its dietary importance.

Deficiency Symptoms
A deficiency in zeaxanthin can lead to low macular pigment density, which may increase the risk of age-related macular degeneration (AMD) and result in free radical cell damage in the eyes.
Synergists & Antagonists
Zeaxanthin works synergistically with lutein, vitamin C, vitamin E, and omega-3s (DHA, EPA) to protect vision, filter blue light, and enhance antioxidant activity. However, high levels of calcium, magnesium, or iron may reduce its absorption, so balanced intake is recommended.

Warnings
Zeaxanthin can interact with large amounts of calcium, magnesium, or iron, which may interfere with its absorption. It is generally considered safe, but consult a healthcare provider if taking mineral supplements.
Food Sources
Zeaxanthin is naturally found in foods like kale, spinach, broccoli, peas, lettuce, egg yolks, corn, kiwi fruit, grapes, zucchini, and other green and yellow vegetables.
Time Frame
Zeaxanthin should be consumed with meals that contain fats, as it is fat-soluble and absorbs better in the presence of dietary fat.
Depleted By
Nicotine can deplete zeaxanthin levels, reducing its protective effects on vision.
