Astaxanthin is a naturally-occurring molecule that has been vastly studied for the last 20 years, with more than 100 human clinical studies and 500 pre-clinical trials showing numerous benefits for the body.

The following list mentions some key findings of Astaxanthin's wide-ranging effects:

  • Higher count of immune T and B cells, improved performance of Natural Killer (NK) cells, and lower levels of DNA damage as well as pro-inflammatory proteins
