D3: What's the Difference? You can get vitamin D3 from sun exposure and meat, such as fish oil and egg yolk
While the body easily absorbs both, research shows that D3 is more effective at raising and maintaining vitamin D levels than D2
In nature, by far the major form of vitamin D that nurtures the body is cholecalciferol
Although it is still named vitamin, in fact it is hormone, a fat-soluble steroid hormone found in two forms, vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol)
Calcitriol is a hormonally-active, synthetic vitamin D analog prescribed to treat hypocalcemia, osteoporosis, and the prevention of corticosteroid-induced osteoporosis
Preclinical and in vitro studies have demonstrated that paricalcitol's biological actions are mediated through binding of the VDR, which results in the selective activation of Stop taking Vitamin D2 and call your doctor at once if you have: chest pain, feeling short of breath; growth problems (in a child taking ergocalciferol); or
