I am surprised Dr Milind Jani's excellent article on free radicals made no mention of selenium tablets.

In the US selenium is in the soil and on the Continent it has been advocated for years.

I am 88 and have been using it for a long time and still manage to go dancing, among other things.

I obtain a whole year's supply for only £8.95 postage paid from Healthspan, PO Box 64, Guernsey G71 3BT.
