For years, there has been debate as to how much Vitamin D is needed in the diet to prevent deficiencies, and recently the recommended levels were officially increased. The following chart reflects the recent changes:
| Age Group | Previous Recommendation | New Recommendation |
| 1-50 years | 200 IU | 600 IU |
| 51-70 year | 400 IU | 600 IU |
| 71 years and up | 600 IU | 800 IU |
| Tolerable
Upper Limit |
2,000 IU | 2,500-4,000 IU
(age dependent) |
