Supplements work as a dietary supplement. In most cases, they are indicated for people who have a very shortage of a certain nutrient. But in general, a balanced diet already plays this role, whether for exercise or for daily life. In addition, the nutrients most commonly found in supplements can easily be replaced with a well-assembled food plate. Most supplements are composed of carbohydrates, proteins and amino acids, which are sufficient nutrients present within a healthy diet.
Many advertisers want to trick consumers into using "fad diets" for optimal health and fitness through supplement promotions. This is a marketing ploy, as people can be healthy with proper nutrition.
