The lab report from my annual check-up just came back and apparently I'm vitamin D deficient. My level is 25 and the normal range is 32-100. My doctor wants me to take 2000 ius of vitamin D daily and repeat the test in 6 months. What advice can you give about vegan vitamin D supplements? Does anyone have a favorite brand? And while I certainly don't want to get osteoporosis, is there any real harm in being slightly deficient when the rest of my health factors are very good? Thanks for the advice.
