Nutritional supplementation refers to the practice of providing nutrients in addition to a person's diet, with the aim of improving their overall health and well-being. This can include vitamins, minerals, amino acids, and other essential nutrients that may be lacking or difficult to obtain through regular food consumption alone. Nutritional supplementation is often recommended for individuals who have specific dietary restrictions, certain medical conditions, or those who want to enhance their athletic performance. The use of supplements should always be done under the guidance of a healthcare professional and in conjunction with a balanced diet.
