I was recently diagnosed with AFib and have been seriously looking into a variety of magnesium supplements. Just came across an interesting interview with Dr. Dean, whose book I've read couple of years ago. Although, she doesn't mention PD, there are some symptoms of Mag deficiency overlapping with symptoms of PD.
Here are the highlights of the interview: How do people become magnesium deficient?
Should calcium be balanced with magnesium?
What tests she recommends for accurately measuring magnesium?
What are the differences between common forms of magnesium?
How does magnesium deficiency relate to mood and other disorders?
