Overview

Brief Summary

The objective of this study is to evaluate and compare the bioequivalence between a single oral dose of vitamin D3 gummy vitamin versus vitamin D3 tablet in healthy adults.

Detailed Description

The investigators hypothesize that the gummy and tablet preparations of vitamin D3 supplement will be biologically equivalent, as defined by the absence of a statistically significant difference in bioavailability measured as blood levels of vitamin D3 after administration of the same dose of gummy and tablet supplementation.
