Your health status, nutritional needs, and dietary intake can change as you age. Maybe you're thinking about taking dietary supplements to ensure you get all the nutrients you need, or maybe you're hoping that a specific dietary supplement will act as a natural remedy or will work as an anti-aging pill.
They'll help you accomplish the first part -- ensure nutrient intake -- but they're not going to turn back the hands of time.
Benefits, Risks and Tips
Dietary supplements have both benefits and risks, but companies that make dietary supplements don't have to prove that they're safe or effective for treating or preventing any type of disease. You need to be careful with dietary supplements, especially as you age. So before you buy, I've got some tips for you.
Consult Your Healthcare Provider: Talk to your doctor or other healthcare provider if you think you need dietary supplements. This is especially important if you're currently taking any medications or have any health issues.
Know What's In the Supplement: Some formulas contain several different ingredients, which increases the chance you'll have some negative side effects. Read the label to make sure you're only getting the nutrients, herbs, or botanicals you want.
Be Aware of Possible Drug Interactions: Some dietary supplements can interfere with medications, even over-the-counter medicines. Vitamin E, for example, has a blood thinning effect and shouldn't be used if you're taking an anticoagulant.
Don't Replace Medications With Supplements: Certain dietary supplements can have drug-like effects on your body. For example, niacin in large doses can reduce cholesterol levels, but if you're currently taking medication to lower cholesterol, don't replace them with niacin (or any other supplement). Niacin can also cause an uncomfortable niacin flush.
Supplements Before Surgery: If you're going to have surgery, you must tell your doctor about all the dietary supplements you're taking. Some supplements, like vitamin E, can have negative effects if taken before or after surgery. You may have to stop taking your supplements at least two weeks before your operation.
Follow Label Directions: Some supplements, like calcium carbonate, are best taken with food, and others -- like iron supplements -- may be best taken on an empty stomach. Don't take a larger dose than what's suggested on the label unless your health provider tells you to do so. Some vitamins are dangerous when taken in dosages much larger than directed on the label.
Don't Believe Any Hype: Avoid any dietary supplements advertised as miracle cures, scientific breakthroughs, or that are sold by websites or companies that make health and anti-aging claims that seem too good to be true. Legitimate supplement companies won't make those types of claims.
If you choose to buy any dietary supplements online, the website should have contact information, including a phone number, so you can contact them with any questions. You may want to ask them what proof they have that the product is effective, and what types of testing and quality control procedures they have in place. If the website doesn't have any contact information, or makes it difficult to speak to an actual human being, then don't buy their product.
