Vitamin D, an essential
vitamin/hormone produced in the skin by ultraviolet radiation, is essential
- calcium balance
- bone density
- immune function
- and proper cell growth.
Recent research suggests many individuals may be vitamin D deficient, especially
those who do not get enough sun exposure, including people in northern latitudes.
Note: Most vitamin D
products on the market contain hidden preservatives. Thorne's D-1000 provides
1,000 I.U. per capsule of pure vitamin D, with no preservatives.
