A growing body of evidence strongly suggests that vitamin D in high doses not only helps keep bones strong but also reduces the risk of colon, ovarian, and breast cancers, and diseases such as diabetes and multiple sclerosis. And many of us don't get enough because of a lack of exposure to sunlight (the sun triggers D's production in the skin) or diets that omit good sources (fatty fish such as salmon, mackerel, and tuna, and fortified milk and cereal). While the official daily dose for people age 51 to 70 is 400 IUs, most experts agree that they should aim for 800 to 1,000 IUs of supplemental D a day. But if you're under 50 and you consume the recommended 200 IUs (the equivalent of two glasses of milk daily) and get 10 to 15 minutes of sun exposure—without sunscreen—a day, a 400 IU supplement should do you fine.

Thank you for this Share!
While Vitamin D will not "save" a life per se, it is very important for all the reasons you mention above. Thank you for this very informative Share and we hope people are eating well, taking a supplement if needed and getting a little sunshine, especially during these times of isolation and quarantine.
