Guava’s edible seeds provide soluble fiber, which helps stabilize blood sugar. Sudden spikes can affect circulation, including the tiny vessels that support the retina. Sarah noticed steadier energy—and sharper morning focus.
5. Beta-Carotene Boost from Pink Guavas
The vibrant color of pink guavas comes from beta-carotene, which your body converts to vitamin A—important for night vision. A deficiency can make low-light environments harder to navigate.
4. Lutein and Zeaxanthin: Nature’s Sunglasses
These carotenoids help filter harmful blue light. Guava contains small but meaningful amounts, and studies show they accumulate in the macula, supporting central vision over time.
3. Polyphenols in Every Part of the Fruit
From skin to flesh to leaves, guava contains polyphenols with antioxidant and anti-inflammatory properties. Chronic inflammation can affect long-term eye comfort and function.
2. Lycopene for Long-Term Eye Vitality
Red-fleshed guavas supply lycopene, a potent antioxidant studied for potential retinal benefits. Sarah enjoyed blending red guava into smoothies, loving the rich texture.
1. The Ultimate Game-Changer: Nutrient Synergy
Guava isn’t about one “magic” nutrient—its power comes from everything working together. Vitamins, minerals, and antioxidants create a supportive environment for overall wellness, including vision.
