Could anybody please advise me if taking Magnesium Citrate causes them to pee more frequently. I was put on a Vit D supplements by my gp as my level was 30. Then I gradually introduced Vit B Complex tablets with no side effects, then Vit K2 MK7, and Vit B12. All was going fine until I introduced Magnesium Citrate which appears to be making me pass urine even more than I normally do with 3 night time trips to the loo. I have a bladder problem (amongst many other things) in that I have no power when passing urine, increased frequency and incomplete emptying of my bladder so this added increase is so not welcome. Just wondered if it was a coincidence or if others have found it affects them too. If so would I get the added Magnesium from Epsom Salt baths and how often should I do this if it would be the better route to for me?
