I'm a noob to the site (but not to TD!) I've just been told I'm vitamin D deficient (19.5!) and I've been given a large dose for the initial boost.
My doc suggested that after the boost I take a daily dose of 800iu - I've been googling and I'm not sure what the difference is between vitamin D, D2 or D3. Please can anyone recommend which is best and some suggestions as to where I might be able to buy it?
Many thanks - hopefully this will help my brain fog and I'll be able to work these things out for myself in future!
