Hey Bizi, Many people have great luck with magnesium citrate in the pill form, just fyi.

When eating low carb, it helps to use fiber . I use citrucel, as i am sensitive to psyllium, etc. no calories. Citrucel also comes in tabs, which is great when you are working all day or on vacation/traveling.

Fiber
Lots of water.
Healthy oils! include fish oil!
Exercise. Even a walk.

docusate sodium (stool softener), if needed.
