Supplements are products that people take to add nutrients to their diet. They can come in various forms, such as pills, powders, or liquids, and often contain vitamins, minerals, herbs, or other beneficial compounds. Many people use supplements to help fill gaps in their nutrition or to support specific health goals, like boosting energy or improving immunity. While some supplements, like vitamin C or omega-3 fatty acids, can be helpful, it's important to remember that they should not replace a balanced diet. Always consult with a healthcare professional before starting any new supplement, as they can interact with medications or cause side effects.
