When it comes to vitamins and supplements, it can be difficult to understand the distinction between over-the-counter (OTC) and prescription dietary supplements. OTC supplements are available without a doctor's prescription, while prescription supplements require a physician's approval. Both offer advantages and have potential risks, but they are regulated differently. OTC supplements often use synthetic or cheaper forms of vitamins, while medical-grade supplements usually contain the best forms of vitamins that ensure your body gets the most effective and natural form of the vitamin.
OTC medicines, vitamins, and dietary supplements don't require a prescription and can be bought in supermarkets, convenience stores, pharmacies, and mass stores. Prescription and OTC drugs are classified as drugs, while supplements are classified as foods. The FDA (Food and Drug Administration) requires that the information on all OTC labels appear in the same order, in an easy-to-read format. Supplements are vitamins, minerals, and herbs that can be used to help the body get enough of certain important substances it needs or to treat or prevent diseases.
However, according to the FDA, supplements cannot be marketed for the purpose of treating, diagnosing, preventing, or curing a disease.Chris D'Adamo, adjunct professor of family and community medicine at the University of Maryland School of Medicine, cautions that different varieties of a particular herb or different extracts can be used in supplements. Another difference between supplements and drugs is that manufacturers are not required to test new ingredients or supplements in clinical trials. It is essential to inform your healthcare provider about all the vitamins, dietary supplements, herbal remedies, and OTC medications you take. Even if you don't need a prescription for them, you should take them responsibly. If your symptoms don't improve or if you experience adverse side effects, you should call your healthcare provider.
