So, I haven't had any RLS in many years - until the last 2 nights! Mostly my severe RLS was settled years ago with iron supplements (ferrous bisglycinate chelate). I have been taking berberine to help with cholesterol support - in the morning (500mg). I recently had my cholesterol checked and decided to move the berberine to the evening (the body produces cholesterol at night). Big mistake! I had some RLS symptoms - not severe at all, but it was there. So, researching berberine it does interfere with iron absorption and I surmise this is the cause. Yesterday, I took the berberine in the morning (as I have for a year or more) and the RLS was there again, but much, much less and dissipated in a few hours. Today I have not taken it at all - we'll see.
There are many posts on Reddit with users experiencing RLS from Berberine supplementation. These are old but never the less...
