Dear Dr. Cannell:
I would like to request that you add allergies to your list of maladies associated with Vitamin D. I did not have issues with allergies as a younger adult, but after menopause, I started to suffer from springtime allergies and mouth allergies from orchard fruits like apples, pears, peaches, plums, apricots, cherries, nectarines, figs, etc. I saw an allergist who diagnosed a birch tree allergy as being responsible for both my seasonal allergy and my mouth allergy.
For ten years, I have suffered with seasonal allergies and experience hives every time I accidentally ingest apple cider vinegar or some other fruit product in a prepared food. Three years ago, I started taking vitamin D supplements after a vitamin D test showed a low level of 8 ng/ml. I started taking 2500 IU of vitamin D daily and over two years my tested levels improved to around 30 ng/ml. This winter I started taking 5000 IU of vitamin D once a week plus 2500 IU per day. By March, my tested levels were 50 ng/ml. This year I have had no problem with seasonal allergies, despite the fact that everyone around me is saying this is the worst allergy season they can remember.
Thanks for all you do. I understand that you do this full time now, trying to spread the word about vitamin D. You certainly helped me, thank you.
