Supplementation refers to the process of adding nutrients to a person's diet to enhance overall health or address specific deficiencies. This can include vitamins, minerals, herbs, amino acids, and other substances that may not be consumed in sufficient quantities through food alone. People often use supplements to support their health goals, such as improving energy levels, boosting immunity, or enhancing athletic performance. Common forms of supplementation include multivitamins, omega-3 fatty acids, and probiotics. While some individuals may benefit from supplements, it is essential to consult with a healthcare professional before starting any regimen, as excessive intake can lead to adverse effects or interactions with medications.
