Astaxanthin Reduces Eye Strain (Asthenopia)
A number of Japanese research studies show the benefit of supplementing with Astaxanthin to counteract eyestrain. A couple of randomized double blind placebo controlled pilot trials demonstrated the positive effects of astaxanthin supplementation on visual function. In one of these studies (Nagaki et al. 2002), the group of 13 participants receiving 5 mg astaxanthin daily for one month showed a 54% reduction of eye fatigue complaints. In a sports vision study of 18 participants (Sawaki et al. 2002), depth perception and critical flicker fusion improved by 46% and 5% respectively in the group receiving a daily dose of 6 mg astaxanthin.
The effect of astaxanthin on visual performance prompted a number of other clinical studies to evaluate the optimum dose and identify the mechanism of action. In a study of 49 healthy volunteers (Nakamura et al. 2004), significant improvements were reported in reducing eyestrain and positive accommodation under 4 mg astaxanthin for 28 days. Furthermore, questionnaire results (Shiratori et al. 2005, Nagaki et al. 2006) confirmed the previous findings that astaxanthin supplementation at 6 mg for 4 weeks improved eyestrain associated with tiredness, soreness, dryness and blurry vision.
Another study (Takahashi & Kajita 2005) also demonstrated that astaxanthin attenuates induced eye fatigue, as opposed to treating eye fatigue, which suggests prevention rather than treatment. Groups given astaxanthin (asthenopia negative) were able to recover quicker than the control group after heavy visual stimulus. Later results (Iwasaki & Tawara 2006) also confirmed the same tendencies of subjective eye fatigue complaints in a randomized, double blind, placebo controlled, double-crossover study.
