Summary

  • What is astaxanthin?

    Astaxanthin is a red carotenoid and antioxidant that is naturally produced by microalgae and may also be produced synthetically (see What It Is).

  • What does astaxanthin do?

    Astaxanthin supplements are promoted for a wide variety of uses, such as increasing physical endurance, reducing inflammation, reducing wrinkles, protecting from sunburn, and lowering triglyceride levels. However, the evidence supporting these uses is mixed (see What It Does).
  • Which is the best astaxanthin supplement?

    All of the products tested in this review contained natural astaxanthin, however, one did not contain the full amount claimed. We found that some products were much less expensive than others, enabling you to get the same amount of astaxanthin for as little as one-third the cost. See ConsumerLab's Top Picks for low-dose and high-dose astaxanthin.
  • How do you take astaxanthin?

    Because astaxanthin is fat-soluble, take it with a meal that contains fats or oils to increase absorption. There is no established safe and effective dose for astaxanthin, but daily doses between 4 mg and 18 mg have shown some benefits without reported side effects in clinical studies, although long-term studies are needed. (See ConsumerTips). Red coloration of stool may occur at a dose of 20 mg or more (See Concerns and Cautions for more information).
