I currently live in Taipei, and there is hardly any sun exposure here in winter months. So very recently I started taking 5000IU of Vitamin D3 (by Biovea) and also Vitamin K2 supplement. I have Hashimoto's. I had Vitamin D deficiency when tested in 2014, but since I lived in India back then, it was recommended I improve my sun exposure. I also took cod liver oil capsules daily. It is only recently that I read about the Vitamin D and Thyroid connection.
I have experienced stomach upset (diarrhea) from the time I took Vitamin D supplement (just 3 doses so far). Is this reaction normal? Do I need to take a lower supplement, or try a different product?
