I want to share my story, because I have had success in treating RLS, and I am hoping, that the supplements I am taking, also can help others. RLS started for me about 10 years ago - I am 50 now - and it was getting worse and worse to a point where I almost did not get any sleep. I read a book called The Mood Cure, where some supplements where recommended.
In addition to a daily strong multivitamin, I started taking 600 mg Magnesium, 2500 mcg B12 (5000 mcg the first month) and 400 mcg Folic Acid. This healed the RLS ( I got my sleep back!). I am still taking these supplements and will continue to do so.
But then a year ago I started having (mild) RLS again. I did not understand why, but then I remembered, that Iron might also be the issue, so I started taking Iron daily. This helped, and I can now sleep again. Once in a while I get very mild RLS, when I go to bed - then I know, that I have forgotten to take my Iron (or simply need more) and I use a spray, which helps immediately. I have read, by the way, that you might be in need of iron, even if a test shows otherwise.
I use a spray for the Iron, because this does not upset your stomach, and for the same reason I take Magnesium as Taurate and pure Bisclycinate.
I hope, that those of you that suffer from RLS can find help in these supplements - like I did!!!! Good luck
