Are Vitamins Really Beneficial?

Have you ever wondered if vitamin supplements really work? Taking supplements continues to grow in popularity. People take them hoping to improve their health or to compensate for a poor diet. Vitamins are found in various forms, from high-quality products to quality that’s not so good. Supplements are not required to meet the same FDA standards that drugs do, so it’s important to look for companies that do third party testing to verify the integrity of the ingredients you’re putting into your body. Even if you know you’re getting the highest quality supplements, you still might have one common question—are vitamins really beneficial? For those of us wanting to pursue a healthier lifestyle, here’s what you need to know about vitamins.


What We Know About Vitamins

Supplements can’t take the place of a well-balanced diet. The nutrients that come from whole foods have more benefits than taking them in supplement form. These include fiber, protective antioxidants, and many micronutrients that are in a complex plant.

That said, research shows that vitamins can decrease risk of chronic disease (1). Studies show a link between multivitamins and decreased risk of cancer and heart disease (2).

Nutrient deficiencies can lead to a variety of health problems. If you suspect a deficiency or if you’re experiencing fatigue or weakness, please consult your physician and get blood tests to confirm. Your doctor can then determine the dosage of supplementation.

Risks to Consider When Taking Vitamins

More isn’t always better. Some vitamin supplements can be harmful in high doses, causing mild to severe side effects. Taking many different supplements for no good reason isn’t always good either. It’s best to take them only for appropriate health concerns and nutrient deficiencies. Check your labels for dosage instructions. Make sure to buy supplements from a reputable company and check with your doctor or nutritionist for additional advice.

Keep in mind that supplements can interact with medications, with other supplements, or may not be recommended to take with certain medical conditions. Please check for interactions with your health care provider or nutritionist before starting supplements.
