As a pharmacist, here are the three vitamins I recommend avoiding.

Understanding Dietary Supplements: What You Need to Know
Many people in the United States consume multivitamins and dietary supplements on a daily basis. In fact, studies show that over half of Americans take these products regularly. However, some doctors and pharmacists warn that many of these supplements may not be worth the money. Here’s a look at the most popular types of supplements and what health experts really think about them.
The Truth About Gummy Vitamins
Why Gummy Vitamins Might Not Be Good for You
Gummy vitamins have easily become a favorite for many people, especially children, because they resemble candy. Pharmacist Amina Khan has shared her thoughts on TikTok, emphasizing that gummy vitamins often contain added sugar—around three to five grams per serving. This amount of sugar might not seem significant, but if you take two gummies a day, it can quickly add up. The American Heart Association recommends no more than 25 grams of sugar for women and 36 grams for men each day.
Khan argues that gummy vitamins are almost like eating a sugar pill. She says, "You might as well eat a piece of candy," because the sugar content can lead to unwanted health problems, such as mineral toxicity.
Do Gummy Vitamins Deliver Nutritional Value?
Gummy vitamins are not only sweet, but they also contain less effective doses of vitamins and minerals compared to other forms of supplements. Doctors at UCLA suggest that even sugar-free gummies can lead to digestive issues because they often use other sweeteners. The strongly appealing taste makes it easier to consume more than the recommended dose, which is a particular concern for children.
Health Risks of Overconsumption
Khan advises that gummy vitamins can easily lead to overconsumption. For kids and adults alike, the enticing flavors can cause them to take more gummies than intended, leading to excessive sugar intake and potential health repercussions.
The Problem with Multivitamins
Are Multivitamins Effective?
Multivitamins typically include a mix of various vitamins and minerals. However, Khan notes that the amounts of each ingredient are often too low to make a noticeable impact on health. For many individuals, taking a multivitamin may not provide any real benefits.
A large study conducted at Johns Hopkins University involving 450,000 participants found no positive effects of multivitamins on preventing heart disease. Other research with around 1,700 patients who had previously suffered heart attacks showed that multivitamins did not reduce the risk of further heart issues or mortality.
Dr. Edgar Miller from Johns Hopkins has pointed out that "study after study comes back negative," yet the demand for these supplements continues to rise. The global vitamins and supplements market was valued at approximately $146.14 billion in 2023, showing a clear disconnect between evidence and consumer behavior.
Who Might Benefit from Multivitamins?
While most healthy adults may not need multivitamins, specific groups such as pregnant women or individuals with nutritional deficiencies could still find value in them. It’s essential for these individuals to consult with healthcare professionals to determine their specific needs.
Dissecting Hair, Skin, and Nail Supplements
Are They Worth It?
Khan also addresses the trend of supplements designed for improving hair, skin, and nails. Many people are drawn to these products because of social media popularity. However, Khan argues that these products usually do not work effectively because they target multiple areas at once instead of focusing on specific issues.
For example, people seeking thicker hair could benefit more from targeted supplements like vitamin B8, while those wanting to enhance their skin health might see better results from a vitamin D supplement designed for skin cell regeneration.
What Experts Say
Dr. Pieter Cohen, an associate professor of medicine at Harvard, has stated that there isn’t strong data to support the effectiveness of these hair, skin, and nail supplements. He has expressed skepticism, saying, "I’m not aware of any robust data suggesting that any supplements can treat natural, aging-related hair loss or nail damage."
The Issues with Regulation
Lack of FDA Oversight
One major issue with dietary supplements is that many are not regulated by the FDA. This lack of regulation can make it difficult to know if you are actually getting what is claimed on the product label. Sometimes, manufacturers may include unlisted ingredients that could have adverse interactions with medications.
The FDA typically intervenes only when significant harm from a product is reported, and while they inspect manufacturing facilities, the overall lack of oversight raises concerns about the safety and efficacy of many supplements on the market.
Understanding Your Needs
It’s important to remember that most people get sufficient vitamins and minerals from a well-balanced diet. If you are considering supplements, it’s best to consult a healthcare professional who can help determine if they are necessary for you. Focusing on a balanced diet, rich in fruits, vegetables, whole grains, and healthy fats, can often provide the nutrients your body needs without the risks of overconsumption and wastage associated with unnecessary supplements.
By understanding the limitations and potential dangers of gummy vitamins, multivitamins, and beauty-related supplements, you can make informed choices about your health and wellness.
