A randomized, double-blind human trial was conducted to assess the effect on the plasma carotenoid concentration of 4- or 12-week astaxanthin supplementation (1 or 3 mg/d) of 20 Japanese middle-aged and senior subjects. The plasma carotenoid concentration was significantly higher after the astaxanthin supplementation than that before in both the 1 mg/d (10 subjects) and 3 mg/d (10 subjects) groups.
对20名日本中老年受试者进行了一项随机双盲人体试验，以评估补充4周或12周虾青素（1毫克/天或3毫克/天）对血浆类胡萝卜素浓度的影响。在补充虾青素后，1毫克/天组（10名受试者）和3毫克/天组（10名受试者）的血浆类胡萝卜素浓度均显著高于补充前。
