I answered this last evening but don't see the post.

I take the Citrate form. This came from my EP saying was the easiest absorb. It can sometimes cause digestive issues in some but the Glycimate form is I am told by my EP a good absorbable form also.

It is important you work with your doctors before you add supplements. My EP recommended I take 400 mg. My wife also takes magnesium for digestive help. She takes the Citrate form also 400 mg.

There are many forms out there with specific benefits but they are (per my EP) not as absorbable as Citrate and Glycimate.

I am not sure why my post last evening did not post but here it is again.

Thank you for the kudo. I just have been through so much with my experience with this subject since 2001. Glad I was able to help others.
