Why does DAKE use Vitamin D3 instead of D2?Updated 20 days ago

There are two forms of supplemental Vitamin D — D2 (ergocalciferol, derived from plants) and D3 (cholecalciferol, derived from animal sources or lichen). D3 is the form your body naturally produces when skin is exposed to UVB sunlight, and research consistently shows it raises and sustains blood levels of 25(OH)D — the marker your doctor tests — more effectively than D2. D2 converts to a slightly different metabolite, is less potent at equivalent doses, and clears the body faster. For a supplement built around actually moving your levels, D3 is the only form worth using.
