hi amy, welcome to the forum. glad to hear someone tested both d3 and magnesium. sounds like they were on the right track. do you have your exact lab test results? did they give you any diet/supplement recommendations? consider adding a zinc test into the mix, unless they tested that already. if you're interested, you might like to read some of the info in my 'signature' links below. ttfn!
