Add3 400 IU Capsule is used for maintaining bone strength and nutrient balance. It supports the body's natural calcium absorption mechanism by delivering vitamin D3 (cholecalciferol), a fat-soluble nutrient essential for bone mineralisation. It helps maintain normal bone density and contributes to muscular strength. The capsule supports immune health and emotional wellness, especially in individuals with limited sun exposure. Add3 400 IU Capsule also assists in the regulation of phosphorus levels, which works in synergy with calcium for better skeletal strength.
