The essentials

A closer look.

Life Extension Vitamin D3 1,000 IU delivers cholecalciferol, the same form the body synthesizes from sunlight, to support calcium absorption, bone density, and immune function. At a moderate 1,000 IU dose, it's well-suited for those maintaining already-adequate vitamin D levels or supplementing alongside dietary sources.

Why It's Worth Considering: Life Extension uses cholecalciferol, the more bioavailable D3 form over D2, in a softgel format that supports absorption alongside dietary fat.
