A study to compare how the body absorbs and processes two types of Vitamin D3 capsules one made from plants (VITADEE Green, vegan) and one made from animal sources in healthy adults who take a single dose while fasting.

A randomized, double-blind, single-center, single-dose, single-period, two-treatment, parallel oral bioequivalence study of Vitamin D3 1500mcg equivalent to 60,000 IU Vegan capsule (containing VITADEE Green) in comparison with Vitamin D3 1500mcg equivalent to 60,000 IU softgel capsule (animal source) in healthy adult human participants under fasting conditions. - VIBE
