Northfield Labs Vitamin D3 1,000 IU vs Verdana Botanicals Vegan D3 2,000 IU
Lanolin D3 vs vegan lichen D3
Why the prices differ
Lichen-sourced D3 generally costs more to produce than lanolin-sourced D3. Normalizing to 1,000 IU also matters: one product is 1,000 IU per serving and the other 2,000 IU.
