Dietary Supplements: Things To Know
What are nutritional supplements?
A nutritional supplement is a vitamin, mineral, or herb that you eat or drink to improve your health but have no nutritional value. These supplements are not intended to cure or treat diseases, unless they are passed a health certificate by the U.S. Food and Drug Administration (FDA).
Vitamins, minerals and nutritional supplements
Vitamins and minerals, also known as micronutrients, nourish the body and help keep you healthy. You can get most of the micronutrients by eating a variety of foods in your daily diet. Getting micronutrients through food ensures that your body can absorb them properly.
If you don't eat a variety of healthy foods, such as fruits, vegetables, lean meats and fish, you may not get all the micronutrients you need

Tips for taking nutritional supplements
Consult your doctor before starting any nutritional supplement.
Do not exceed the recommended dosage on the label unless recommended by your doctor.
Read the ingredient list to make sure you know the other ingredients in the nutritional supplement you're taking.
Just because a nutritional supplement is advertised as "natural" doesn't mean it's safe.
Make sure your doctor knows about all the nutritional supplements you take because they may interact with certain medications.
How do I know if I should take nutritional supplements?
If you are concerned that you are not getting enough vitamins and minerals from your diet, ask your doctor how to get the micronutrients you need. Depending on your overall health, the vitamins or minerals your diet lacks, your doctor may recommend a dietary supplement. If you want to take a nutritional supplement, talk to your doctor about why you want to take it and what you hope it will bring you.
Your doctor can also tell you if there is a nutritional supplement that interacts with the illness you are suffering from, or with any prescription or over-the-counter medications you are taking. Nutritional supplements can also have adverse effects on cancer treatment or surgery, including bleeding and problems with anesthesia.
How safe are nutritional supplements?
Some manufacturers of nutritional supplements follow the USP Pharmacopoeia quality standards.
Nutritional supplement manufacturers that comply with USP quality standards voluntarily let their products be tested for quality and purity by an outside company before they are sold. These products often have additional quality information labels, such as "approved by the USP" or "quality approved by nutritional supplements, and ask your family doctor or pharmacist." Your doctor if you have questions.
