I also recommend taking 1000 IU (or 25 micrograms) of vitamin D daily. A lack of vitamin D may not only affect the health of our bones, but also increase our risk for high blood pressure and heart disease. Some studies suggest that as many as 5 to 10 percent of adults are deficient in vitamin D.30 Some of this is due to reduced exposure to the sun, since sunlight can stimulate vitamin D synthesis in the skin. However, vitamin D deficiency is more common in people who are obese or have metabolic syndrome, occurring in up to 75 percent of these children or adults.
