What is the effect of elemental sulfur on the body?
First things first: Inorganic sulfur is completely non-toxic to our body because it remains undigested as it passes through the digestive tract and is excreted again. But what it makes available to the body are its electrons, which the free radicals present in the gut pounce on. So they don't rush into the electrons of our cells, so that the cells can stay healthy.
This is how sulfur becomes a protection against the so-called "free radicals".
