I have been taking vitamin d3 at a dose of 10,000 iu per day (5000 am and pm) to try to help my chronic hives, and I think I've stumbled on help for my period pain as my last period was close to pain free! I've only been taking d3 for 3 weeks and know I need to keep an eye on my levels (10,000 iu per day seems ok but any higher can cause kidney problems) but wanted to share in case it helped anyone else. Always check with a medical professional before starting this kind of supplementation as there may be contraindications for you depending on other health issues or medications. Has anyone else tried this and had some relief?
I realise this may be a fluke as I've only had one period since commencing d3.
