Swanson Vitamin D3 High Potency delivers a daily dose of 25 mcg (1,000 IU) of Vitamin D3 (cholecalciferol) in an easy‑to‑take capsule. Vitamin D3 is a fat‑soluble nutrient that plays a crucial role in maintaining overall health, especially for bone strength, immune support, and muscle function.

Vitamin D3 is the form of vitamin D that your body naturally synthesizes from sunlight exposure. It helps regulate calcium and phosphorus balance, which is essential for building and maintaining strong bones and teeth. Adequate Vitamin D3 supports the absorption of dietary calcium and helps prevent deficiencies that can lead to bone weakness.

In addition to its role in bone health, Vitamin D3 contributes to immune system function by aiding the activity of immune cells that protect against infections. It also supports muscle health and neuromuscular coordination, making it particularly important for overall physical performance and balance.

This high‑potency formula provides 1,000 IU per capsule, allowing for convenient once‑daily supplementation. With 250 capsules per bottle, it offers a long‑lasting supply for everyday use as part of a balanced health regimen.
