NSF Certified for Sport®
The EyePromise Vizual Edge product line is the first and only line of eye vitamins to earn the prestigious NSF Certified for Sport® designation, ensuring that all EyePromise Vizual Edge Chewable, EyePromise Vizual Edge PRO, and EyePromise Vizual Edge products are free of more than 180 banned substances. The National Sanitation Foundation (NSF) is the only third-party public safety company recognized by most professional sports organizations.
The NSF Certified for Sport® mark ensures that the supplement is free of athletic banned substances and contaminants of concern. The certification process requires:
- Toxicological and label review to verify product formulation
- Product testing to verify and quantify dietary ingredients declared on product label
- Good Manufacturing Practices (GMP) audits
- Contaminant screening, which involves testing to ensure there are no ingredients present that have not been declared on the label nor are there unsafe levels of contaminants
- Banned substance screening to certify the product is free of prohibited substances on World Anti-Doping Agency’s (WADA) list, NFL, MLB and NCAA prohibited substances lists. This includes screening for over 160 athletic banned substances.
The NSF certification process also requires ongoing monitoring and testing to ensure the product(s) certified by NSF International continue to comply with these requirements. The NSF Certified for Sport program is recognized by major sports organizations that include:
- The National Football League (NFL)
- Major League Baseball (MLB)
- National Hockey League (NHL)
- Canadian Centre for Ethics in Sport (CCES)
- The Ladies Professional Golf Association (LPGA) and the PGA
- The World Anti-Doping Agency (WADA)
The EyePromise visual performance product line is backed by over 20 years of research!
A Randomized Placebo-Controlled Study On The Effects Of Lutein And Zeaxanthin On Visual Processing Speed In Young Healthy Subjects.
Supplementing with higher levels of dietary Zeaxanthin daily, improves temporal contrast sensitivity function (visual processing speed) and Macular Pigment Density versus a placebo in young, healthy subjects.
A Double-Blind, Placebo-Controlled Study On The Effects Of Lutein And Zeaxanthin On Neural Processing Speed And Efficiency.
Increasing macular pigment density through supplementation with higher levels of dietary Zeaxanthin daily resulted in significant improvements in visual processing speed, even when testing young, healthy individuals who tend to be at peak efficiency.
A Double-Blind, Placebo-Controlled Study On The Effects Of Lutein And Zeaxanthin On Photostress Recovery, Glare Disability, And Chromatic Contrast.
Daily supplementation with Zeaxanthin and Lutein resulted in significant increase in serum levels and MPOD and improvements in chromatic contrast and recovery from photostress in young, healthy adults. These results are consistent with past studies showing that increasing MPOD leads to improved visual performance.
Macular Pigment And Visual Performance In Glare: Benefits For Photostress Recovery, Disability Glare, And Visual Discomfort.
Higher macular pigment levels, which can be achieved with dietary Zeaxanthin supplementation, correlate with improved photostress recovery time, reduced glare disability, and less visual discomfort.
The Influence Of Dietary Lutein And Zeaxanthin On Visual Performance.
High 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.
Supplementing with 20 mg of dietary Zeaxanthin daily increases macular pigment optical density. 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.
