Why this category disappoints so often
Walk down any supplement aisle and you'll see labels listing fifteen ingredients under one "proprietary blend" — a single combined weight, no individual amounts. It looks impressive. Most people never check whether any single ingredient is actually dosed at a level that could do anything.
Five things to check
Proprietary blends. No individual doses means no way to verify anything.
Disease claims. "Reverses" or "cures" Alzheimer's isn't legal for a supplement to claim. Walk away.
Vague mechanism. If the brand can't explain what each ingredient does, the formula probably wasn't built around one.
A short guarantee. Fourteen days, unopened only, is designed to expire before you could fairly judge it.
No real contact. A legitimate company has a findable address and a working support line.
What a good label looks like
Every ingredient with its own listed amount. A small set of ingredients with a story you can follow. Made in an FDA-registered facility. A guarantee that runs sixty days or more and accepts opened product.
Simple test: can the brand explain, in one sentence, why each ingredient is there and roughly what dose the research used?
Fewer ingredients, dosed properly, usually wins
Six well-chosen ingredients at real doses, each doing something distinct, beats twenty ingredients spread too thin to matter individually.
The guarantee tells you the most
A company confident in its formula doesn't make refunds difficult. Check whether the window starts at purchase or delivery, and whether it requires a minimum trial period — thirty days of use with a sixty-day claim window is a realistic structure for something meant to work gradually.
One question worth asking
Could you explain this formula's logic to a friend in two sentences? If the label is a wall of names with no clear story, that's usually the tell.
Price tells you less than you'd think
A higher price doesn't reliably mean a better formula. A lot of that cost is marketing and packaging, not ingredient quality. Judge the label itself — dosing, mechanism, guarantee — rather than what the price implies.
Questions worth emailing support
Before buying, three questions are worth asking directly: what research backs each ingredient at this dose, where is it actually made, and what exactly does the guarantee cover. A brand that's done the work answers clearly. One that hasn't tends to redirect to testimonials instead.
