Here’s use vitamin D safely and effectively.


1. Buy the D3 form of vitamin D. According to the US National Institutes of Health, the D3 form of Vitamin D is much more effective than other types. In addition the Vitamin D council reports that other forms of vitamin D can cause hypercalcemia, very high levels of calcium in the blood, which can be dangerous. D3, however, is a safe flu remedies and does not cause hypercalcemia. D3 is available in 1,000 iu increments, over-the-counter, at pharmacies and other retailers. Larger increments of Vitamin D are more easily found online (see Resources for a link to a reputable online supplier).

2. Take 5,000 iu of D3 per day, for adults, when healthy to boost the immune system and prevent flu. The Vitamin D Council recommends 1,000 iu for children under the age of 1 and 2,000 iu for children between the ages of 2-4 years. From the ages of 4 through 9 the suggested dose is 3000 iu. At the age of 10, children may take the adult dose of Vitamin D.

3. Increase the D3 dose at the first sign of illness to 10,000 iu for adults. Higher doses have been used in human during medical studies without ill effects, but 10,000 iu is currently the highest recommended dose. However, if flu relief does not result after a few days, you may want to consider increasing the vitamin D dose. Consult a pediatrician for the correct dose for children. An alternative to taking a supplement would be to expose skin to the sun at midday for 15-20 minutes.
