Overview

Each capsule of Momentous Vitamin D3 delivers 5,000 IU, and the 60-capsule bottle carries NSF Certified for Sport status alongside a gluten free formulation.

NSF Certified for Sport matters specifically to competitive athletes subject to drug testing, since it screens for banned substances rather than just confirming label accuracy. This is a single-ingredient D3 capsule rather than a combination multivitamin, and the dose is high relative to typical over-the-counter D3 products.
