Vitamin D-1000

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.
