Overview

A once-weekly vitamin D3 capsule delivering 50,000 IU (1250 mcg) as cholecalciferol, sold in a 60-capsule bottle sized as a one year supply at that weekly dosing.

This is a high-dose, once-a-week format rather than a daily softgel, which suits someone managing a diagnosed deficiency under guidance rather than routine daily supplementation. The capsule is a gluten free veggie capsule, not a softgel.

  • 50,000 IU per capsule
  • Once weekly dosing
  • Gluten free
  • Veggie capsule form

Who it's for

Fits someone who wants an infrequent, high-strength D3 dose instead of a daily pill, often because low vitamin D levels have already been flagged. Not suited to anyone wanting a standard daily maintenance dose, since 50,000 IU weekly is a therapeutic-range strength.

Strengths and trade-offs

Performance notes

Cholecalciferol is the D3 form the body converts most readily, and the 1250 mcg per-capsule strength is dosed for weekly rather than daily intake, spreading a 60-count bottle across roughly a year.
