Vitamins are vital organic compounds that support various bodily functions, including metabolism, immune health, and skin maintenance. Dr. Neeti Sharma, a dietitian at Marengo Asia Hospitals, explains that vitamins are divided into two categories: water-soluble and fat-soluble. Water-soluble vitamins, such as Vitamin C and the B-vitamins, must be consumed regularly as they are not stored in the body. Fat-soluble vitamins, including Vitamins A, D, E, and K, are stored in fatty tissues and require dietary fats for absorption. Women have unique nutritional needs, particularly for iron and vitamins C, B, and D, due to factors like menstruation. While vitamins are essential, excessive intake can lead to adverse effects, such as nausea and kidney problems. A balanced diet rich in whole foods is recommended to meet vitamin requirements safely. Supplements may be beneficial in certain situations, but it's crucial to consult a healthcare professional before taking them to avoid side effects and ensure appropriate dosage.
