A high percentage of the population is Vitamin D deficient regardless of sunscreen use. The Recommended Daily Intake is way too low. Most people would be better off if they supplemented Vitamin D.
Recent studies have shown that people really should be supplementing 1000-2000 IU, that it has a safe upper limit of ~10,000 IU. The RDI is currently like ~500IU.
