Sulphur is an element that imparts antioxidant properties to molecules containing it. For example, glutathione, pioneered by Dr Perlmutter, contains sulphur.(English spelling!!) In the last 5 years, 25,000 medical articles have been published on glutathione.
Mirapex (pramipexole), also contains sulphur.
Some molecules contain sulphur in an oxidised form, eg zonisamide, so they don't show antioxidant properties. They contain sulphur with oxygen atoms directly attached, they don't have the unoxidised form -S-.
Selenium, is also an element that imparts antioxidant properties. It is in the same group of elements as sulphur in the periodic table.
All useless information!!!
