A Safety Study on the Long-Term Consumption of Astaxanthin in Healthy Human Volunteers / 日本補完代替医療学会誌

ABSTRACT

A long-term safety study was conducted with astaxanthin derived from <i>Haematococcus pluvialis</i> algae extract. Fifteen healthy volunteers took 9 mg of astaxanthin daily for 12 weeks. Physiological (including doctor’s consultation), haematological, biochemical, and urinary markers were examined at weeks 0, 4, 8 and 12. No adverse effects or clinical changes were observed throughout the test period. It was concluded that a healthy adult can consume 9 mg of astaxanthin derived from <i>Haematococcus pluvialis</i> algae extract for 12 weeks without any safety concern.<br>
