Clinician’s Corner: New Labeling of Vitamins

Our vitamin section will be changing.  Because of FDA mandatory label changes, the measurements in “international units” will be phased out.  One of our most popular fat-soluble vitamins is Vitamin-D-2000iu, soon that will be replaced with Vitamin-D 50mcg.  There is no difference between these two products.  The new labeling will be mandatory for all vitamin brands in the coming years.

Your Thompson Pharmacist will be glad, as always to guide you through the vitamin section.  At Thompson Pharmacy it’s all for YOU!
