An updated meta analysis shows that the vitamin D levels are inversely proportional to the mortality rate. As the vitamin D levels go up, the mortality rate goes down.
The safe dose of vitamin D supplementation per day in the general population is approximately 2000 UI, but it varies from person to person. People who are overweight may take 3000 UI daily, while those who are obese may need more. Moreover, people who do not get enough vitamin D from the sun are required to take up to 3500 UI daily to get their Vitamin D level in range.
Vitamin D regulates the amount of calcium and phosphate in our bodies and is required for building bones, teeth and muscles. Vitamin D also helps in preventing cancer growth, reduces inflammation and helps control infections.
Our daily diet and limited exposure to the sun makes it hard for our bodies to get enough Vitamin D that they need. Vitamin D supplements, therefore, are important to fulfill the daily vitamin D needs in our bodies.
