- What is astaxanthin? Astaxanthin is a red carotenoid and antioxidant which 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, and lowering triglyceride levels. However, the evidence supporting these uses is mixed. One study suggests it may also reduce wrinkles in healthy adults. (See What It Does).
- Best choice of astaxanthin? All of the products tested in this review contained natural astaxanthin at the amounts listed on their labels and were not contaminated with heavy metals. However some are 3 times less expensive than others. See CL's Top Picks section.
- How to 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).
