Vitamin D is an elusive nutrient for many in the modern world, just like omega-3s, which is why so many health professionals encourage increased intake. But as research continues at a frenetic pace, the focus has evolved to put more emphasis on one’s vitamin D blood level. In other words, because of the complex factors at play when it comes to sun exposure, intake, and metabolism—as well as gender, genetics, lifestyle, to name a few—it cannot be predicted with certainty what someone’s vitamin D level is just based on how much they take.

This is the same premise behind Omega-3 Index testing. While dosage is an important guideline for people, knowing what their level is first will go a long way toward pinpointing a more precise

It is produced when the body is exposed to sunlight (ultraviolet B radiation sunlight). Our bodies are amazingly efficient when it comes to producing vitamin D3; brief
