Have clinical studies been conducted for astaxanthin?
There have been numerous preclinical in vivo and in vitro studies and several human clinical trials to evaluate the efficacy of astaxanthin. A double-blind, placebo-controlled study demonstrated that astaxanthin was found to significantly increase strength and endurance. Another clinical study shows that astaxanthin alleviates symptoms in patients with H. pylori (pre-ulcer indigestion). A third clinical study demonstrated bioavailability in humans. Additional human clinical studies are being sponsored.
