I belong to the RLS Foundation, as do many of you. But for those who do not, I have just discovered, by chance, that some of their best lectures, from some of the best experts, are now available on YouTube.
Here is the lecture from Doctor Christopher Earley of the Mayo Clinic, on Iron in RLS. It is unassailable science from a renowned expert, for those of you who have skittery doctors.
The history of how we arrived at 'normal iron levels' is particularly interesting.
Follow this link, and you will discover other lectures from the Foundation. And bear in mind that the RLS Foundation is a non-profit, and the scientists involved are not being paid by Pharma, but by members and donors.
And then, please, join the Foundation, because the work they do is helping all of us.
