Dietary supplements are a source of nutrients that could not obtain from our normal diet. They come in many forms, including capsules and tablets, powders and liquids, and may comprise a wide range of nutrients such as nutrients, minerals, proteins or fiber as well as herbs and extracts. Nutrition supplements are intended to enhance a healthy diet and lifestyle. They can be utilized to treat specific nutrient deficiencies, support general health and well-being and improve the performance of athletes or increase muscle size. However, it is important to remember that supplements shouldn't be considered a replacement for eating a healthy diet and consulting with a healthcare provider prior to beginning any new program of supplementation is recommended.
