Some Antioxidants Reduce Vasodilators:
"Antioxidant therapies that reduce levels of vasodilators will reduce oxygen delivery to muscle.
'We're now learning that if antioxidant therapy takes away hydrogen peroxide – or other naturally occurring vasodilators, which are compounds that help open blood vessels – you impair the body's ability to deliver oxygen to the muscle so that it doesn't work properly,' Poole said.
The body produces free radicals to serve signaling functions. Unfortunately these same free radicals damage us."
