Vitamin D-3 1000 IU by GNC is a food supplement in tablet form, providing vitamin D3 (cholecalciferol) as its main active ingredient. Each tablet delivers 25 µg (1000 IU) of vitamin D3, supplying 500% of the reference nutrient intake for adults.
This tablet format is a straightforward option for adults who want to add a fixed daily amount of vitamin D3 to their routine, particularly during months with limited sunlight exposure.
Vitamin D3 (cholecalciferol) is a fat-soluble vitamin that the body can also produce through skin exposure to sunlight, though dietary and supplemental sources become more relevant when sun exposure is limited. Vitamin D3 contributes to the normal absorption and utilisation of calcium and phosphorus, and supports the maintenance of normal bones and teeth. Each tablet in this product is formulated to deliver a consistent 25 µg dose, making it straightforward to track daily intake. The calcium present comes from an excipient used in the tablet's composition rather than being added as a separate active ingredient.
The tablet is intended to be taken with a meal and a glass of water, as part of a daily routine.
