Want to agree with Catriona from Dublin about too much Vitamin D being not good. After contracting long-haul Covid, it was only with taking extra Vitamin D and Zinc that finally brought an end to 4 months inflammation in my chest wall and joints. So I kept taking both for the next year as I wanted to ensure I wouldn't go through that again. But about 3 months ago, I began having cloudy urine that became over time stronger smelling and eventually became Intermittent Cystitis.
With no infection present, I realized it may be time to reevaluate my nutritional supplements. After I eliminated the extra Vitamin D from my daily regimen, my bladder immediately began to calm down. 6 weeks later, I now have only occasional issues whenever my daily vitamin D intake rises above the norm. I maxed out on D-- if I hadn't cut it back, I could have done lasting damage to my urinary tract. I've since read that long term vitamin D excess has been linked to kidney problems. Definitely don't want that!
