I'm about 12 weeks pregnant and my constipation is becoming worse and worse...before I was doing ok with a regular magnesium supplement but I was wondering if magnesium citrate would be more helpful. I've used Natural Calm when I lived in the US but now I'm in Prague and they don't sell Natural Calm anywhere in Europe. I could order it from the US, or even ebay, but with the shipping cost it ends up being really expensive. My mother-in-law is visiting in June so she can bring me some but that's still 2.5 months away...I was wondering if other magnesium citrate supplements (such as made by Now Foods or Solgar) would be as helpful as NC? Usually they come in a pill form. I can get those from other EU countries and they're much more affordable. I need to know for sure, though, because if they're going to be the same as my regular Mg supplement (magnesium oxide) then it's just a waste of money and time ('cause I'd have to order online) for me. I would especially appreciate hearing from anyone who's tried both NC as well as other supplements before, but I'm happy with any input. Thanks!
