I was suggested to take it by my RheumBA for my fatigue. There was no difference in me after 3 months of supplementing.
I do know it is thought to help various symptoms in many illness. It is thought to help with migraines. Maybe that is why your doctor prescribed it.
Anything none toxic, food type of supplement is worth a try providing there is no drug interactions, allergic reactions, side effects.
Have you researched the supplement so you know what side effects to look for?
Enjoy the day..
I have Lupus. So *^#@! what.
