Description: Nutritional supplements are products designed to complement the daily diet, providing nutrients that may be lacking or not consumed in sufficient amounts through food. These products can contain vitamins, minerals, amino acids, fatty acids, fibers, and other bioactive compounds. Their form can vary, including tablets, capsules, powders, liquids, and bars. The relevance of nutritional supplements lies in their ability to help maintain optimal health, support physical and mental performance, and prevent nutritional deficiencies. In a world where food can be insufficient or unbalanced, supplements offer a practical solution for those looking to improve their overall well-being. However, it is important to remember that they should not replace a balanced diet but should be used as a complement to meet individual nutritional needs.
History: Nutritional supplements have their roots in antiquity, when herbs and natural extracts were used to improve health. However, their modern development began in the 20th century, with the identification of essential vitamins and minerals. In the 1930s, vitamin supplements began to be marketed, and in the following decades, the industry grew exponentially, driven by scientific research and consumer demand. In 1994, the Dietary Supplement Health and Education Act in the U.S. established a regulatory framework that allowed greater access to these products.
Uses: Nutritional supplements are used for various purposes, such as improving overall health, increasing energy, supporting the immune system, and aiding muscle recovery after exercise. They are also common in specific populations, such as the elderly, pregnant women, and athletes, who may have particular nutritional needs. Additionally, they are used to treat or prevent nutritional deficiencies in individuals with restrictive diets or health conditions that affect nutrient absorption.
Examples: Examples of nutritional supplements include multivitamins, which combine various vitamins and minerals; protein powders, used by athletes to increase protein intake; and omega-3 fatty acids, commonly found in fish oil and known for their cardiovascular health benefits. Other examples are probiotics, which help maintain gut health, and vitamin D, which is essential for bone health.
