Nutraceuticals are bioactive compounds derived from food sources that provide health benefits beyond basic nutrition. They bridge the gap between food and medicine, offering therapeutic effects such as disease prevention and overall well-being improvement. Common types include dietary supplements, functional foods, and medicinal foods, often rich in vitamins, minerals, antioxidants, probiotics, and herbal extracts. The growing interest in nutraceuticals stems from their potential to support immune function, heart health, cognitive function, and more, making them a key component of modern health and wellness trends.
