As many as 1 in 200 people may have iron overload - that's a lot of people out there who should be going near the Floradix/Spatone etc..
From my above link
"Haemochromatosis is uncommon in general terms, although it is one of the most common genetic (inherited) conditions in England.
As many as one person in 200 may be affected.
Symptoms usually start around the age of 40 in men and after the age of 50 in women. Symptoms in women are delayed because their iron levels are reduced when they have a period.
Haemochromatosis is most common in people of white European ethnic background – particularly people of Irish descent."
