Restless leg syndrome is often caused by a magnesium deficiency.
Magnesium is good for your muscles as it helps to relax them.
I started with the restless legs recently and got on the magnesium and that has really helped tremendously.
Magnesium is good to prevent insomnia, constipation and restless leg syndrome.
I take a supplement around noon and another around 8:00 pm to keep the restless legs from starting.
I've also had the same restless feeling in my arms before.
Give it a try and allow 4 to 5 days for it to build up in your system to get the affect. Possibly sooner.
