Vitamin D is a fat-soluble vitamin known as the sunshine vitamin. It helps in the absorption of calcium in the intestines and maintains serum calcium and phosphate concentrations, which are essential for bone growth and strength. This prevents rickets in children and osteomalacia in adults. Vitamin D also plays roles in reducing inflammation, modulating cell growth, neuromuscular function, immune function, and glucose metabolism. It is beneficial in preventing diseases such as osteoporosis, cancer, cardiovascular diseases, diabetes, depression, obesity, and multiple sclerosis. Vitamin D is available in two main forms: cholecalciferol (animal-derived) and ergocalciferol (plant-derived), both of which are well absorbed by the body. This product contains vitamin D in the form of cholecalciferol.

Vitamin D deficiency is common among infants, the elderly, people with limited sun exposure such as housewives, individuals with specific clothing styles, night workers, those with darker skin, people with malabsorption syndromes, and obese individuals. Therefore, it can be supplemented through dietary supplements to meet daily requirements. The recommended daily allowance (RDA) for vitamin D in adults is 15 micrograms (600 IU), and the maximum allowable daily intake (UL) is 100 micrograms (4000 IU).

This product provides 1000 IU of vitamin D per capsule. For more information, refer to the article by Dr. Elaheh Abdollahi, pharmacist.
