Astaxanthin is a natural pink carotenoid best known for giving salmon and shrimp their pink-red color. It is grown from microalgae, the same kind that fish eat in the ocean. The best way to get a super concentrated form of this pigment is from a supplement. At Lindberg®, our premium triple strength formula provides 12 mg of microalgae-derived Astaxanthin (Haematococcus pluvialis) per quick-release softgel. It's gluten-free, non-GMO and easy to add to any routine for adults.
