Vitamin D3 · Immune & Bone Support

Vitamin D-1,000

Vitamin D needs vary widely by person — Thorne notes that the right amount depends on individual factors, which is why it's offered across several strengths. Vitamin D-1,000 delivers 25mcg (1,000 IU) of vitamin D3 per capsule, the form Thorne states is more potent and better absorbed than D2, sized as an everyday maintenance dose.

Each bottle contains 90 capsules — enough for up to three months at once daily, or as your healthcare practitioner recommends. It's formulated without lactose or preservatives like BHT, BHA, sodium benzoate, and sorbic acid, and third-party tested to confirm what's on the label matches what's in the capsule, with no unsafe levels of contaminants such as heavy metals, pesticides, and microorganisms.
