Astaxanthin
: Astaxanthin is classified as a xanthophyll, which is a carotenoid pigment that can be found in microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds. Astaxanthin has been suggested as a possible treatment for autoimmune disorders, but human studies are currently lacking.Avoid if allergic to astaxanthin or related carotenoids, including canthaxanthin. Use cautiously if taking 5-alpha-reductase inhibitors, drugs that affect blood pressure, asthma medications, drugs that are broken down by the liver's cytochrome P450 system, menopausal agents, birth control pills, or Helicobacter pylori agents. Use cautiously with high blood pressure, parathyroid disorders, or osteoporosis. Avoid with hormone-sensitive conditions, immune disorders or if taking immunosuppressive therapies. Avoid if low esosinophil levels or if visual changes have occurred while taking astaxanthin. Avoid if pregnant or breastfeeding. Read more
