Nutraceuticals are products derived from food sources that offer health benefits beyond basic nutrition. They can include vitamins, minerals, herbs, and other dietary supplements that may help prevent diseases or promote overall well-being. Common examples of nutraceuticals are omega-3 fatty acids, probiotics, and antioxidants. These products are often marketed as natural alternatives to pharmaceuticals, but they are not regulated as strictly. While some studies suggest that nutraceuticals can support health, it is essential to consult with a healthcare professional before starting any new supplement regimen to ensure safety and effectiveness.
