1. Protection from Disease
Antioxidants protect your cells and your DNA from oxidative damage caused by free radicals. Oxidative damage, in turn, causes chronic inflammation and creates an environment ripe for the spread of disease. Spirulina has plenty of antioxidants to bind with free radicals and neutralize them before they can cause this chronic inflammation.
The main active antioxidant in spirulina is called phycocyanin. This antioxidant is also what lends spirulina its unique blue-green color. Beyond fighting free radicals, phycocyanin has been shown to inhibit production of certain molecules that signal the body to spark inflammation.
