Supplement myths don’t seem to go away, they just get recycled with a new spin. Whether it’s a half-true “tip” on social media or something passed down through word-of-mouth, misinformation can steer people toward products that don’t help and sometimes even do harm. Backed by verified research, we’re working to debunk these myths and empower consumers to make smarter choices when it comes to their health.
We already covered some of the biggest myths in our last post, but here are even more supplement myths that are still surprisingly common.
Myth #1: You Can’t Overdose on Vitamins
This is one of the most dangerous myths out there. Just because something is sold over the counter doesn’t mean it’s always safe in high amounts. Fat-soluble vitamins (A, D, E, and K) can build up in the body and potentially cause toxicity if taken in excess. For example, short term Vitamin A overdose can cause nausea, headaches, dizziness, or blurred vision (1). Long term overdose can cause hair loss, liver enlargement, bone abnormalities (1). Even some water-soluble vitamins, like B6, can lead to issues like nerve damage when mega-dosed over time (2). Always stick to clinically recommended dosages, consult with a qualified healthcare practitioner, and check your total intake across all supplements and fortified foods.
Even when a vitamin is essential, too much of a good thing can quickly become harmful. That’s why organizations like the National Institutes of Health (NIH) and the Institute of Medicine (IOM) have established Tolerable Upper Intake Levels (ULs)—the maximum daily amount of a nutrient that’s considered safe for the general healthy adult population. These limits apply to total intake from food, fortified products, and supplements combined. Not all vitamins have established ULs, but for those that do, exceeding them regularly can increase the risk of side effects, nutrient imbalances, or even toxicity.
✔ Research Verified carefully selects ingredient levels based on clinical data, ensuring safe and effective dosages – not simply flashy numbers. However, if you intend to use more than one supplement with the same vitamin, it is imperative that you check that you are not overdosing on any of the vitamins.
Myth #2: Supplements Are Only for Older Adults
While many people associate supplements with aging , the truth is that nutritional gaps can happen at any age. Whether you’re in your 20s juggling a demanding schedule, in your 40s navigating hormonal changes, or in your 60s focused on maintaining vitality, your body’s nutrient needs are always shifting. Busy lifestyles, chronic stress, poor sleep, food intolerances, medications, or restrictive eating habits can all contribute to vitamin and mineral shortfalls — and they don’t discriminate by age.
Even if you’re eating a relatively balanced diet, it’s not always enough to cover everything your body demands. Modern food processing, soil depletion, and on-the-go meals can reduce the nutritional value of what ends up on your plate (3,4). That’s where supplements come in — not as a replacement for a healthy diet, but as targeted support. They can help fill in the gaps, optimize your wellness routine, and support you by promoting healthy energy levels, mood, digestion, skin, and sleep, no matter your age or stage of life.
✔ Research Verified formulas supports wellness across every stage of adult life and help with specific health concerns as well as overall wellbeing.
Myth #3: If It Worked for Someone Else, It’ll Work for Me
Listening to your friends’ testimonials and reading reviews are a great indicator as to whether or not a supplement can work. However, they can’t tell you if the product will work for you specifically. Every body is unique and therefore, results will vary. For example, though coffee is most commonly used as a stimulant to increase wakefulness, there are individuals who feel more tired as a result of coffee (5). Your diet, age, health conditions, genetics, any medication you take and your lifestyle all play a role in how your body responds to a supplement. What worked wonders for your friend might not be right for you, and that’s okay. The key is to choose products with science-backed ingredients and positive reviews that indicate it is highly likely to work for you. For this reason, many manufacturers offer a money-back guarantee if the product doesn’t meet your expectations.

Myth #4: Multivitamins Cover Everything
Multivitamins are a helpful foundation, but they don’t meet every nutritional or therapeutic need. Think of them as nutritional insurance; they offer a broad spectrum of essential vitamins and minerals, usually at low to moderate doses. That’s great for general wellness, but not always enough if you’re trying to address a specific concern. For issues such as joint discomfort, cognitive function, or hormone balance, you need targeted support. Multivitamins tend to leave out powerful botanicals and specialty ingredients (like adaptogens, amino acids, or herbal extracts) that have been shown in studies to target specific systems in the body.
✔ All Research Verified formulas are designed to address a specific need and improve wellness.
Myth #5: Supplements Don’t Interact With Medications
This is a dangerous assumption. Just because a supplement provides natural ingredients, doesn’t mean that it can’t have a negative effect. If a supplement can benefit your health, it can also interact with any medications in your system. Some supplements can amplify or interfere with prescription drugs, including blood thinners, antidepressants, and antibiotics. For example, BioPerine (a black pepper extract used to enhance absorption) can alter how certain medications are metabolized in the liver, potentially increasing their potency – which can be dangerous if you need a specific potency that isn’t too strong.
These interactions can vary depending on your dosage, health status, and the specific medications you’re taking. That’s why it is essential to talk to your healthcare provider before starting any new supplement, especially if you’re managing a medical condition or taking prescriptions regularly.
✔ Research Verified formulas are clearly labeled with full ingredient transparency, helping you and your doctor make informed choices.
More Supplement Red Flags to Watch For
Still unsure what’s real and what’s just good marketing? Here are more warning signs:
🚩 Marketing with vague, unverified claims like “biohacks your system”.
🚩 Supplements sold with no list of clinical studies or references.
🚩 Flashy packaging with no mention of testing or certifications.
🚩 Celebrity or influencer endorsements with no scientific backing.
✔ Every Research Verified supplement is rooted in transparent labeling, third-party testing, and real science.
