question: Hello I recently have plagued with big mood swings and low libido, I went to the doctor have been diagnosed with severe vitamin d deficiency (10 ml), my doctor prescribed me Vitamin D2 50,000 iu. This is my second week on it, my first week I had 3 or 4 days where I felt pretty good, and even noticed small improvements in libido, but it didn t last past that. I have seen that people have had better results with vitamin d3. Should I look into it as well?
