Vitamin D is not “just a vitamin,” but rather, it’s a pre-hormone that affects mood, energy, and immune health.
We have 30,000 genes in our body and vitamin D has been shown to influence more than 2,000 of them! We're likely just beginning to scratch the surface of its true potential for reversing the modern disease state.
Vitamin D deficiency is rampant today, due to most Americans spending the majority of their time indoors. Additionally, living at higher latitudes (like in the Pacific Northwest) puts you at increased risk of Vitamin D deficiency. In fact, even if you spend every day outside, it's impossible to be fully replete with Vitamin D if you live in Portland.
Why is this problematic? Vitamin D deficiency has been linked to an astonishingly diverse array of chronic diseases and conditions, including Alzheimer's, arthritis, asthma, autism, cancer, cardiovascular disease, Crohn's disease, dementia, depression, diabetes, eczema, hypertension, infertility, macular degeneration, multiple sclerosis, obesity, osteoporosis, periodontal disease, psoriasis, and rheumatoid arthritis.
Researchers have calculated that simply increasing levels of Vitamin D could prevent diseases that claim nearly 1 million lives throughout the world each year! Vitamin D can decrease your risk for common respiratory infections as well. The higher your Vitamin D level, the lower your risk of getting colds, flu, and other respiratory tract infections. Low levels of Vitamin D were associated with an increased risk of acquiring COVID-19, having a more serious infection, and progressing into long haul COVID.
While Vitamin D deficiency is only recognized conventionally at levels < 30 ng/ml, optimal Vitamin D status is 70-90 ng/ml.
However, before you start supplementing ..you can have too much of a good thing! Vitamin D toxicity can occur and it is difficult to reverse. This is why it is important to test your levels before beginning Vitamin D supplementation.
If you are supplementing with vitamin D, take it with food. Vitamin D is fat-soluble so will be better absorbed with a little bit of fat, rather than if you take it on an empty stomach.
