Myth vs. Fact: Supplements Edition


Not everything you hear about supplements is true. Tap a myth to reveal the science.
Myth: Multivitamins can replace a healthy diet
Supplements can help fill nutritional gaps, but they don’t replace the benefits of whole foods like fiber, antioxidants, and phytonutrients.
Myth: More is better – high doses mean faster results
Some vitamins (like A, D, E, and K) can build up to harmful levels. Follow science-backed dosage guidelines and avoid megadosing unless under medical supervision.
Myth: Natural means it’s always safe
Natural doesn’t always mean harmless. For instance, St. John’s Wort can interact with antidepressants, birth control, and other medications. Always research or consult a professional.
Myth: You’ll feel the effects of supplements immediately
Some nutrients (like omega-3s and magnesium) may take weeks or months to show benefits as they build up in your system.
Myth: All supplement brands are basically the same
Not true. Some brands prioritize quality testing, transparency, and bioavailability — others cut corners. Look for third-party tested supplements.
Myth: Creatine damages the kidneys
Numerous studies have shown that creatine is safe for healthy individuals at recommended dosages, with no damage to kidney function.
Myth: You don’t need supplements if you eat healthy
Even a healthy diet can fall short due to soil depletion, food processing, or life stage needs. Supplements can fill gaps.

Myth: If a supplement worked for my friend, it’ll work for me
Everyone’s body is different — diet, genetics, and health status affect how we absorb and use nutrients. Personalization matters.
Myth: Protein supplements are only for bodybuilders
Protein supports muscle repair, immune function, and healthy aging — not just for gym-goers. Many adults benefit from supplementation, especially if intake from food is low.
Myth: If it’s sold in stores, it must be safe
Supplements aren’t FDA-approved before sale. It’s up to manufacturers to ensure safety — always look for third-party testing.
