Chapter 1: The Truth About Vitamins and Supplements

If you're one of the 52% of Americans who take at least one vitamin or dietary supplement daily, you might want to reconsider your choices. A thorough analysis of 277 clinical trials reveals that most of these products, including multivitamins, do not enhance heart health or extend lifespan.

The findings are not particularly shocking. Despite the staggering $40 billion spent annually on vitamins and supplements in the U.S., numerous studies have raised doubts about their effectiveness, and most supplements lack regulation. This means you may not be receiving what you believe you are purchasing, and there is a scarcity of credible studies assessing their safety or effectiveness.

Experts emphasize that, aside from specific medical conditions where a physician prescribes supplements, the best approach to achieving good health is through a well-rounded diet rich in fruits and vegetables.

“The search for a miracle cure in dietary supplements is futile,” states Erin Michos, the senior author of the study and an associate professor at Johns Hopkins University School of Medicine. “Individuals should aim to obtain their nutrients from a heart-healthy diet, as increasing evidence suggests that most healthy adults do not require supplements.”

The study, published in the Annals of Internal Medicine, indicates that while most of the vitamins and supplements analyzed did not pose any risks, only a few may provide health benefits—specifically omega-3 fatty acids (fish oil) and possibly folic acid for certain individuals.

Crucially, researchers also discovered that combinations of calcium and vitamin D might elevate the risk of stroke. The vitamins and supplements reviewed included:

• Antioxidants
• Vitamin A
• Beta carotene
• Vitamin B-complex
• Vitamin B3/Niacin
• Vitamin B6
• Vitamin C
• Vitamin E
• Vitamin D (alone)
• Calcium (alone)
• Calcium and vitamin D combined
• Folic acid
• Iron
• Multivitamins
• Omega-3 fatty acids
• Selenium

The study also assessed various diets:

• Mediterranean diet
• Reduced saturated fat diet
• Modified dietary fat intake
• Reduced-fat diet
• Low-salt diet for healthy individuals and those with hypertension
• Increased alpha-linolenic acid (ALA) diet (nuts, seeds, and vegetable oils)
• Increased omega-6 fatty acid diet (nuts, seeds, and vegetable oils)

Among these diets, only the low-salt diet demonstrated potential health benefits, according to researchers.

While more research may further clarify these findings, it is not uncommon for scientific perspectives and health recommendations to change over time. Nevertheless, this extensive study, along with other recent investigations, casts significant skepticism on an industry that often relies on anecdotal evidence and aggressive marketing tactics.

The key takeaway from Michos and her team: Save your money.
