As the name suggests, dietary supplements are substances intended to supplement an individual’s regular diet. Herbs, vitamins, minerals, and herbs are all classified as dietary supplements, and they are regulated by the Food and Drug Administration as food products. Under current regulations, dietary supplements do not undergo the same tests medications must pass to be sold. Nevertheless, most doctors recommend patients take a multivitamin, and some dietary supplements such as iron, vitamin B12, calcium, and fish oil could help in the case of nutritional deficiencies or as protection against cardiovascular disease. Supplements may not be safe for everyone, and experts encourage patients to check with a doctor before taking a supplement; this is especially important for patients who are taking other medicines and for those with underlying health conditions. Patients scheduled for surgery may need to stop taking certain supplements for a few days or weeks before their operation. When taking a supplement, patients should never take more than the recommended dose on the label, and they should let their doctor know if they develop any worrying symptoms.
Some of the most common side effects associated with dietary supplements are discussed below.
Nausea describes an inclination to vomit, and it can occur with or without actual vomiting. Taking high doses of supplements increases the risk of nausea. For example, patients who take vitamin C supplements in doses of more than two thousand milligrams are particularly likely to experience this side effect, and nausea is also a recognized side effect of magnesium supplements. Patients who take supplements should let their doctor know if they begin to experience nausea regularly, especially if it begins after starting a new supplement. In rare cases, nausea could be one of the first signs of an overdose of magnesium or another supplement. Nausea that occurs together with low blood pressure, diarrhea, muscle weakness, or fatigue should be investigated promptly. To relieve nausea at home, patients might want to sip ginger tea or suck on peppermint candies. Going outside to get fresh air may help reduce queasiness, and doctors advise patients to eat light meals comprised of soft, bland foods until nausea passes. Foods such as white rice, broth, and crackers may be beneficial.
