Our verdict

A single D3 capsule with the strength written plainly and a broad support list. The allergen listing is thorough, though timing advice is missing.

Overview

A daily one-capsule routine is what this THORNE vitamin D3 serves, supplying cholecalciferol without flavor. The listing names bone, teeth, muscle, heart and immune function as the areas it supports.

The strength is easy to read and the free-from list covers the usual allergens plus fish and shellfish. It is a single nutrient, so anyone expecting a multivitamin will not find one here.

Who it's for

People who want a modest vitamin D3 capsule and need to avoid gluten, dairy, soy, fish or shellfish get a clear fit. Shoppers wanting several vitamins together should consider a different product.

Pros and cons

Pros
  • Strength written in the title
  • Long allergen free list
  • Bone and immune benefits listed
  • Ninety servings per bottle
Cons
  • Single nutrient only
  • Timing advice not listed

Performance notes

Vitamin D3 is fat soluble, so taking it with a meal containing some fat is the usual advice, though the listing does not say so. A small capsule is swallowed whole, with no taste to manage.
