i've been taking it for while....only about
950 IU...but will up it a bit now that the season is changing. I'm not a sun person, so definitely don't get any that way.
I did have my level checked, but the doc didn't call back to say if I'm deficient. My husband, who doesn't have any autoimmune problems that we know of..was severely deficient and was on 2000 IU for 3 months and is down to 1000 IU and takes an extra 1000IU every few days.
*Heather* Status..Asacol 6 (3 twice daily); enemas every 4th night
~diagnosed January 1989 UC (proctosigmoiditis)
~Bentylol (dicyclomine) 20mg as needed
~Probiotic 4(Natural Factors Protec) bedtime + Primadophilus Reuteri Pearls occasionally
~multi-digestive enzymes as needed
~Ranitidine,Pariet (reflux); Effexor XR 75mg(depression); Pulmicort/Airomir (asthma)
~URSO for PSC (or PBC) 500mg X 2 daily (LFTs back to NORMAL!!)
My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
