Vitamin D-1,000 - 180 Servings
This supplement fills a critical gap for active people who spend time training indoors or live in low-sunlight climates—vitamin D3 is essential for bone density, muscle function, and immune resilience that your body relies on to perform. Thorne's straightforward 1,000 IU formula delivers bioavailable D3 without unnecessary additives, so you're getting exactly what your body needs to support recovery, strength, and long-term health.
Thorne Vitamin D-1,000 provides 1,000 IU of vitamin D3 per serving — a form recognized for superior absorption compared to D2 — across 180 servings. Formulated without lactose or common preservatives, it suits those with limited sun exposure who want a simple, consistent addition to their daily wellness routine.
Thorne’s D-1,000 contains 1,000 IU of high-quality vitamin D3. Although it is well known that direct sunlight is a natural source of vitamin D, many individuals, especially the elderly, don’t get enough vitamin D from sunlight or from their diet. Be sure you get the vitamin D your body needs with Thorne’s easily absorbed Vitamin D-1,000.
