Teri are you at a latitude at which you’re able to catch some mid-day “rays?

Hi to both Terris @windwalker and @tdrell. Recently I read that high dose vitamin D can also boost the 'natural antibiotic' -- cathelicidin -- that the lung's macrophages produce. This helps to kill off mycobacteria.
(Mycobacteria often live inside the macrophages in our lungs. Cathelicidin is produced in macrophages to kill off bacteria -- it's an important part of the immune system. People who succumb to MAC MAI don't produce enough natural antibiotic inside their macrophages).
High dose Vitamin D once every 2 or 3 months is something I want to try. Thanks for reminding me, Annie

Hi. What is a recommended dose of vitamin D? I'm taking 125 mcg a day at bedtime? I've taking it for a number of years. Not sure the reason I started taking it but sounds like it was a good thing to do.
