Welcome to Wellwise’s special section on astaxanthin, the ‘radical defender' – we call it the radical defender because of its unequaled ability to scavenge free radicals in the body. In this section you will find a storehouse of information about this remarkable antioxidant, and the many ways in which astaxanthin may benefit your health.
You can begin your journey of discovery here by clicking on any of the links below, or use the navigation bar at the top of each page to pursue your particular interest.
First we explore:
• The ways in which astaxanthin is grown – Haematococcus pluvialis, the algae that produces the most astaxanthin is cultivated in both closed and open environments
• Astaxanthin’s role in nature – which includes slowing the process of oxidation in animals’ bodies and protecting them from UV light damage
• Exercise performance – results are preliminary, but in animal models, astaxanthin supplementation increased endurance capacity and significantly decreased the accumulation of fat
• Eye health – this nutrient may have even stronger antioxidant activity than lutein and zeaxanthin in terms of protecting against UV-light damage
• Cardio health – When there’s more astaxanthin around, production of HDL cholesterol (the “good” kind) goes up, and LDL cholesterol(the “bad” kind) is protected from free-radical damage
• Immune health – astaxanthin supplementation improves activity of natural killer cells, which target and destroy cells that have become infected with viruses
• Men’s health – infertility and low testosterone respond to astaxanthin
• Skin health – Astaxanthin has been shown to protect the skin from UV damage that would otherwise damage skin DNA, and do so even better than other carotenoids such as beta-carotene and lutein
As with most dietary supplements and drugs, people are concerned with side effects. We examine
• Astaxanthin dangers – There have been at least eight clinical studies using more than 180 humans using astaxanthin to assess its safety, bioavailability and clinical aspects relevant to oxidative stress, inflammation or the cardiovascular system. No adverse outcomes have been reported.
• Recommended astaxanthin dosage – Various human clinical studies have safely used a very wide range of astaxanthin doses for as long as a year
