Has anyone heard of vitamin D effecting menstruation? I started 10000 iu a day about 4 weeks ago. My original test # was 25. I had my first period about 4 days early and have continued to spot every day after. This is really unusual for me and the only difference I've made is the d3. Thoughts?

    Not sure what to say. Maybe only the first period after the D will be a little off then go back to normal. Vitamin D can have a huge impact on everything.

    It’s doubtful vitamin D brought your period early, but as IAW commented above vitamin D can have a huge impact on everything. It’s more likely you experienced ovulation earlier than usual, which shortened your menstrual cycle. I highly recommend Taking Charge of Your Fertility by Toni Weschler:


    Her book is an evidence-based treasure trove for women of reproductive age.

    A pregnancy test and perhaps a trip to your doc might be in order too.

    A lot of things were affected when I started taking 10,000 IUs of vitamin D. It all came down to needing magnesium for me. Vitamin D, birth control pills, and many medications use up magnesium. Magnesium deficiency can cause a hormonal imbalance and I too was spotting throughout the months as my vitamin D levels increased. I also got foot and leg cramps and increased anxiety.
