A nutraceutical is a substance that is either a food or a component of a food that has medicinal or health benefits, such as disease prevention and treatment. Nutraceuticals are a class of products that are neither food nor medications. Unfortunately, there is still no internationally agreed-upon definition for these products, thus opinions vary from country to country. Nutraceuticals are used as part of dietary supplements in most nations. In affluent countries, nutraceuticals are used by 50–70% of the population, and this percentage is rising as people get older. Nutraceuticals are used by women more than men. Nutraceuticals are safe products from a safety standpoint.
Vitamins, minerals, herbs, and amino acids are common ingredients in nutritional supplements, which are used to improve one's diet. Any dietary supplement that is designed to supply nutrients that would otherwise be insufficiently ingested, such as vitamins, minerals, proteins, amino acids, or other nutritional elements, is referred to as a nutritional supplement. Capsules, tablets, and liquids are the most common forms of products consumed. Supplements are frequently connected with complementary and alternative medicine (CAM), which comprises a wide range of medical and health-care systems, practises, and products that are not considered part of conventional medicine.
