EyePromise visual performance formulas are backed by over 20 years of research. Read summaries of extensive studies validating the effectiveness of zeaxanthin below:
The Zeaxanthin and Visual Function Study (ZVF)
- This study showed that supplementing with 8 mg of dietary zeaxanthin daily led to a 54% increase in macular optical density (MPOD) at 12 months. Indications are that higher MPOD scores hold a direct correlation with improvements in visual acuity, shape discrimination, contrast sensitivity, and general visual performance.
Macular Pigment and Visual Performance in Glare: Benefits for Photostress Recovery, Disability Glare, and Visual Discomfort
- The study showed that higher macular pigment levels could be achieved with dietary zeaxanthin supplementation. This points to the potential of improved photo-stress recovery time, reduced glare disability, and less occasional visual discomfort
The Influence of Dietary Lutein and Zeaxanthin on Visual Performance
- Higher daily intake of dietary zeaxanthin and lutein increases macular pigment levels. Macular pigment acts as a filter of blue light, reducing the visual discomfort associated with indoor and outdoor lights.
The Effects of Macular Carotenoid Zeaxanthin on Visual Performance and Neural Efficiency in Young, Healthy Subjects and College Athletes
- The study showed that supplementing with 20 mg of dietary zeaxanthin daily increases macular pigment optical density. A denser macular pigment is directly related to improved vision, contrast sensitivity, reduced glare disability, increases in temporal processing (processing of fast moving objects), and improvement in fixed and variable reaction times.
Indications are that supplementing with 20 mg of dietary zeaxanthin daily improves visual performance. EyePromise visual performance products are the only nutraceuticals containing 8, 10, or 26 mg of dietary zeaxanthin in a single serving.
