Without a Healthy Gut, Vitamin D May Not Work
Several studies have suggested that a person’s vitamin D levels have an important impact on overall, long-term health. A study from the University of California San Diego explored the connection between the gut microbiome and a person’s levels of active vitamin D. The research team learned that there is an important link between the two, and without a healthy gut, vitamin D may not work. (1, 2)
This study also contributed new understandings about vitamin D and how it’s measured. Although vitamin D can appear in different ways in the body, we usually only measure one of its forms because it’s the only one that appears on standard blood tests. This form is an inactive precursor, which the body has the ability to store. But in order to use it, the body has to metabolize the precursor form of vitamin D into an active form. (1, 2)
