The Details
Why you'll love it
Vitamin D is less of a vitamin and more of a hormone — and it influences the expression of over 1,000 genes in your body. Despite its critical importance, an estimated 42% of American adults are deficient, with rates even higher in people with darker skin tones, those who live in northern latitudes, and anyone who spends most of their time indoors.
The consequences of deficiency are far-reaching. Beyond its well-known role in calcium absorption and bone health, vitamin D is a key regulator of immune function. It activates your innate immune system's first responders (including antimicrobial peptides like cathelicidin) and helps modulate the adaptive immune response to prevent overreaction. Low vitamin D is consistently associated with increased susceptibility to respiratory infections.
Vitamin D also supports muscle strength (deficiency is linked to increased fall risk in older adults), mood regulation (low levels correlate with seasonal depression), and cardiovascular health. We use D3 (cholecalciferol), the same form your skin produces from sunlight, at 5,000 IU — a dose supported by research for achieving and maintaining optimal blood levels of 40-60 ng/mL.
