Vitamin D3enhances calcium absorption and retention, a key nutritional function in supporting healthy bones and teeth. Decreased exposure to sunlight, a vegetarian diet and a low intake of vitamin D-fortified foods often contribute to inadequate vitamin D levels. Clinical studies involving vitamin D supplementation suggest the importance of both vitamin D and calcium for bone health. Calcium intake, when combined with sufficient vitamin D, a healthy diet and regular exercise, may reduce the risk of developing osteoporosis. Vitamin D supplementation alone also supports bone health. It promotes intestinal calcium and phosphorous absorption, and reduces urinary calcium loss, essential mechanisms for maintaining proper calcium levels in the body and healthy bone composition.
