Astaxanthin: relieves eye fatigue

Update:09-11-2019

Using natural liquid chromatography, natural astaxanthin extracted from Haematococcus pluvialis was present in the ciliary body aorta 24 hours after feeding to rabbits. Astaxanthin has many effects on the eyes. Several human clinical studies have reported that after one month of oral administration of astaxanthin, there is a significant effect of improving visual fatigue. In addition, astaxanthin also has an anti-inflammatory effect.
 
Research details
The Department of Ophthalmology, Kanazawa Medical University, Japan, together with Fuji Chemical and Japan, investigated the levels of astaxanthin in the eyes and serum levels of rabbits after taking astaxanthin for 24 hours. METHODS: After natural oral administration of 100 mg/kg of single-dose natural astaxanthin, it was analyzed by high performance liquid chromatography for 168 hours to detect its content.

Result
The results showed that the serum astaxanthin concentration reached a maximum after 9 hours (61.3 ng/mL), and the astaxanthin concentration in the iris ciliary reached a maximum after 24 hours (79.3 ng/mL). In another study of oral astaxanthin, the concentration of astaxanthin in serum reached a maximum in 9-12 hours. According to HPLC test data, astaxanthin did not appear in the anterior chamber eyes. Although astaxanthin is highly likely to be present in the anterior chamber eye, the concentration is very low.
                       
Meaning
This may be the first study: it has been shown that astaxanthin is also present in the eyes of rabbits by oral administration. This research can be used in humans, but further research is needed. This study has made us more convinced that astaxanthin has a great effect on relieving human eye fatigue.
