Many detox and diet products contain harmful ingredients if tested at all, notes the United States Food and Drug Administration. There is little scientific evidence that drinks and other products for detoxification are effective or necessary, as the human body removes toxins well, according to Mayo Clinic.
Detox drinks are often a part of diets lacking calories and solid food, which can leave consumers low in blood sugar, vitamins, muscle mass and beneficial internal bacteria, reports NBC. People should not take detox drinks over the long term but should ingest more vegetables, whole grains and other less refined foods, advises WebMD. Individuals only feel as if detox drinks work because they are avoiding foods high in fat or sugar, suggests Mayo Clinic.
