Genestra D3-2500 offers 2,500 IU (62.5 mcg) of vitamin D3 (cholecalciferol) per capsule, supporting the body's absorption and utilization of calcium and phosphorous. This high-potency supplement helps maintain optimal vitamin D levels, which are essential for overall health, as the vitamin D receptor is found in nearly all human cells. Adequate vitamin D is vital for numerous physiological processes, yet many Canadians experience deficiency due to limited sun exposure, clothing choices, low dietary intake, dark skin tone, aging, or insufficient supplementation. Taking just one capsule daily can help prevent vitamin D deficiency and, when combined with sufficient calcium intake, a balanced diet, and regular exercise, may reduce the risk of osteoporosis.
