Vitamin D is generally measured in either micrograms (mcg) or International Units (IU). This is what you will see listed on the side of supplements etc. It is easy to convert between the two; 1 mcg = 40 IU. Regards, Marek.

Fantastic research review and I appreciate the concerns and suggestions you've given. Couple of things though, not familiar with the measurement units you've provided or found in your lit review (IU, ng, mcg).
Thanks!
