Red Flags in Product Marketing
Health product marketing is optimized to exploit anxiety and bypass critical thinking. These are the patterns that should make you pause before buying. Not every flag means the product is bad, but each one means you need to dig deeper before trusting.
Proprietary blends
A proprietary blend lists the total weight of a combination of ingredients but does not disclose the individual doses. This is legal under FDA rules. The label might say "Cognitive Blend 800mg: bacopa, lion's mane, ginkgo, rhodiola" without telling you how much of each.
The problem: clinical studies use specific doses. Bacopa works at 300mg. If the entire blend is 800mg across four ingredients, each could be underdosed. Brands hide behind proprietary blends to use expensive ingredients at trace amounts while listing them prominently on the label. Demand products that disclose individual doses.
"Clinically studied"
This phrase sounds authoritative but often collapses under scrutiny. Questions to ask: Was the study on this specific product, or on one ingredient in it? Was the study dose the same as the product dose? Was the study published in a peer-reviewed journal, or is it an unpublished in-house trial? Was the study funded by the brand itself?
A supplement can legally say "clinically studied" if any ingredient in it has appeared in any study, even if the study used a different dose, different formulation, different population, or found no benefit. The phrase is technically accurate and practically meaningless.
Testimonials over data
When a product page leads with customer stories, influencer endorsements, or before-and-after photos instead of lab data or clinical evidence, the marketing is doing the work that the product cannot.
Testimonials are not evidence. They are susceptible to placebo effects, selection bias (only positive experiences are shared), and outright fabrication. A product that works should be able to show measurable, reproducible data, not just anecdotes.
No third-party testing
If a brand does not publish a Certificate of Analysis from an independent, ISO 17025 accredited lab, you have no verification that the product contains what the label says or is free from contaminants. Learn how to read a COA and learn how to commission your own testing.
"Tested in-house" or "quality assured" without third-party verification is self-graded homework. The incentive structure does not favor honesty when the tester and the seller are the same entity.
NMR vs HPLC: inflated potency
Some supplement brands use NMR (Nuclear Magnetic Resonance) testing to report potency instead of HPLC (High-Performance Liquid Chromatography). NMR can produce higher-looking numbers because it measures all structurally similar compounds, not just the specific active ingredient.
A curcumin supplement tested by NMR might report 95% curcuminoids, while HPLC testing on the same product shows 75%. Neither number is "wrong" -- they measure different things. But the brand using NMR is choosing the method that makes their product look better. HPLC is the more relevant measure for consumer decision-making. See lab testing methods.
Fear-based marketing
The pattern: "Your water is poisoning you. Your supplements are fake. Everything you eat is toxic. Only our product can save you."
Fear-based marketing creates urgency that bypasses rational evaluation. Real contaminant risks exist (lead in water, heavy metals in supplements), but they require measured assessment, not panic. A brand that leads with fear is selling an emotion, not a solution.
The antidote: look at the data. What does the COA say? What do the labels actually mean? What do the regulatory thresholds say? Base decisions on measurement, not marketing.
