In the study by Yeh and coauthors, 50 female Wistar rats received an injection of streptozotocin (STZ) to induce diabetes and were then randomly selected into four groups that received daily for eight weeks: normal saline; 0.6 mg/kg astaxanthin; 3 mg/kg astaxanthin; 0.5 mg/kg lutein. Kono and coauthors conducted a randomized double-blinded study to investigate whether the use of multiple dietary supplement containing lutein, astaxanthin, cyanidin-3-glucoside and docosahexaenoic acid (DHA) would improve accommodative ability of aged and older subjects who complained of eye strain.
