An astaxanthin ingredient marketed by BGG World as AstaZine Natural Astaxanthin was shown to support visual function in people over the age of 40 in a recent human clinical study appearing in the Journal of Clinical Biochemistry and Nutrition.
 
The study enrolled 60 healthy adults whose vision was tested after prolonged use of visual display terminals for work. The groups were administered either a placebo or 9 mg per day of astaxanthin for a duration of six weeks.
 
In subjects over the age of 40, the authors observed significant improvements in the visual acuity and pupil constriction rate of the dominant eye, suggesting that astaxanthin reduced the oxidative stress caused by visual display terminal use. Researchers noted an age-related reduction in ciliary muscle strength was likely the main detractor of visual acuity, and so astaxanthin had a protective effect against the stressor.
 
“This is the second publication for visual health which used AstaZine,” said Yanmei Li, PhD, BGG’s global chief scientific officer. “As we age, doctors believe that key muscles in our eyes lose strength which, in turn, leads to a reduction in our ability to see detail. This is particularly pronounced in people overusing computers and smartphones. Fortunately, supplementing with AstaZine is an effective way to combat this condition that affects so many of us in today’s world.”
