A. We have included links to studies that have been conducted on astaxanthin. But honestly, no one has conducted the types of studies that would normally be done for a new drug to get FDA approval? Why not? Well astaxanthin is a natural compound and so can’t be patented. Without patent protection, no one has a financial incentive to prove it works. However, the amount of scientific studies on astaxanthin is significant as there are over 200 reports in scientific journals.
