Key Moments
Superoxide dismutase disappears after age 30 and algae can replace it
Catherine Arnston explains that superoxide dismutase (SOD), the key antioxidant that neutralizes free radicals inside mitochondria, drops after age 30 and disappears by 50. Most antioxidants cannot enter mitochondria, but chlorophyll, glutathione, and SOD can. Spirulina and chlorella provide these missing mitochondrial protectors.
"Without it, you're basically dead."
Women lose mitochondrial protection from estrogen and get hit harder by aging
Women experience more severe mitochondrial damage than men after 30 because they lose both SOD and estrogen simultaneously. Estrogen acts as an antioxidant inside mitochondria, which is why depression and Alzheimer's are more prevalent in women.
"women are getting hit harder. Their mitochondria are being damaged more frequently than men because of the loss of estrogen."
