Vitamin d and higher blood levels of the vitamin’s active form are shown to lower the risk of colon and rectal cancers, a new analysis of past research finds. 18 past studies comprising of over 10,000 people showed that the risk of colon cancer was as much as 33 percent lower in those who had the highest vitamin d levels compared to those who had low vitamin d levels. People with high vitamin d levels attained primarily through supplements or food showed a 12 percent lower risk than people with the lowest intakes.
Vitamin d has recently been a put on the throne, so to speak, due to it’s massive amount of health benefits. It has been shown to protect people from various cancers, diabetes, heart disease, asthma, and so much more. Unfortunately, up to 58 percent of U.S. adults and adolescents have vitamin d deficiencies.
The best source for vitamin d is the sun. By getting out and having fun you’re killing two birds with one stone – soaking up the vitamin d while being physically active. The next best solution is to supplement with vitamin d3. Foods fortified with vitamin d contain an ineffective form known as vitamin d2. This synthetic form is not what you want to go after.
