Abstract:
This research studied on the efficacy of astaxanthin on lowering blood glucose level in prediabetic subjects (FBS between 100-125 mg/dl). In this study,27 volunteers were randomly divided into 3 groups, each group contained 9 volunteers. Placebo, astaxanthin 4 mg/day and astaxanthin 8 mg/day were given in group 1, 2 and 3 respectively. All groups were assigned to take supplement for 8 weeks. The result was found that there was not reduced significantly of FBS and HbA1C in volunteers after taking astaxanthin for 8 weeks. When compared with placebo group, the reducing of FBS and HbA1C level by astaxanthin was lower than the placebo but no statistical significant. Astaxanthin did not have any side effect, abnormal symptoms, liver and kidney toxicity.
