Dietary supplements are defined as a consumable product that supplements your food intake.
In addition to being labeled as a dietary supplement, they must have at least one vitamin, mineral, amino acid, or natural herb, and they must be available to be easily consumed as a tablet, pill, liquid, or mixable powder.
The FDA provides some guidance but does not regulate these supplements.
The general purpose of each dietary supplement is to provide the body with some sort of nutrient or vitamin that it needs but is unable to obtain through everyday foods.
The three basic types of supplements, as mentioned earlier, include herbal supplements, vitamin and mineral supplements, and probiotic supplements.
