The Connection Between Vitamin D and Your Immune System

The connection between vitamin D and your health and well-being is nothing less than amazing. We’d like to thank Vitamin D Wiki for the use of this video. It puts into practical and easy to understand terms the difference in lifestyle and health from 100 years ago to today, and why current generations are having the health problems they are.

It’s more important than ever to boost your immune system and keep in tip top shape. Vitamin D should be a part of your supplement and natural health regimen. Vitamin D has been scientifically proven to successfully prevent and/or treat many viruses.

We recommend the use of Nutrasal’s Micro D-3 for high dose administration.

We suggest the following protocol dose with Micro D-3:

  1. Loading Dose: 3 loading doses of 300,000 IU shall be administered every 4th day. The loading dose shall be taken once daily in the morning or evening with food.. Micro D-3 dose: 300,000 IU = 4.5 ml.
  2. Booster Dose: A booster dose of 50,000 IU shall be administered every 4th day after the loading dose is completed. The booster dose shall be taken once daily in the morning or evening with food. Micro D-3 dose: 50,000 IU = .75 ml.
  3. Daily Dose: A daily dose of 10,000 IU shall be administered daily on non-loading dose and non-booster dose days. The daily dose shall be taken once daily in the morning or evening with food. Micro D-3 dose: 10,000 IU = 5 drops.

A minimum of a 90 day administration period is recommended during cold and flu season.  However, daily doses should be maintained throughout the summer as well if sun exposure is limited.

Studies suggest that daily doses of 50,000 IU are safe (No Observed Adverse Effects) and quickly raise blood levels with in days when compared to smaller daily doses, which can take 2-3 months to get blood levels high enough to be effective.

Our recommendation calls for much larger doses of vitamin D.  The evidence suggests that even much larger doses have been proven both safe and effective for most people. This is especially true in the short term.  As with any supplement or medication we always recommend checking with your doctor or healthcare provider about any contraindications or interactions with other medications you may be taking.
