Health Effects of Vitamin D2
Vitamin D2 (ergocalciferol) is a plant/fungal form of vitamin D. It contributes to calcium homeostasis and bone health, though with somewhat lower potency than D3 in raising serum 25(OH)D levels.
Same as general vitamin D deficiency. D2 is less effective at maintaining serum levels than D3, so relying solely on D2 sources may leave levels suboptimal.
Same toxicity profile as vitamin D generally. D2 is cleared from the body faster than D3.
Absorption & Interactions
Absorbed identically to D3 in the small intestine with dietary fat. Both forms undergo the same hepatic and renal activation steps, but D2 has a shorter half-life and lower binding affinity for vitamin D-binding protein.
