SCS - Does BioShield have too much Vitamin D?

The Office of Dietary Supplements at The National Institute of Health states that the safe upper limit to Vitamin D is 100 mcg or 4000 UL for ages 19 and up (found near the end of the webpage).

BioShield MD contains 37.5 mcg or 1500 UL, and new studies show that higher dosages of Vitamin D offer more benefits than average consumption rates.

The Vitamin D dosage is safe.
