Our review process

How We Review Supplements

We review supplements from a buyer’s perspective, not as a medical authority. Our goal is to help readers understand what a product claims, how it is sold, what terms apply, and what safety questions should be considered before purchase.

We do not present supplements as cures, treatments, or guaranteed solutions. Instead, we focus on practical information that can help shoppers avoid confusion, unrealistic expectations, and questionable sellers.

1

Ingredient & Label Transparency

We look at listed ingredients, formula positioning, label clarity, and whether the product explains its intended use in a reasonable way.

2

Official Seller & Bundle Checks

We review official-site bundle options, checkout paths, seller information, and whether pricing or discounts are clearly explained.

3

Refund & Shipping Terms

We check guarantee periods, refund conditions, shipping details, discreet billing information where relevant, and return-policy limitations.

4

Safety Notes & Claim Review

We flag exaggerated medical claims, unrealistic promises, marketplace risks, and reminders to speak with a qualified healthcare professional when appropriate.

Buying Supplements Online? Watch for These Red Flags

The supplement market can be confusing, especially when multiple sellers, fake “official” pages, aggressive ads, and unrealistic claims appear in search results.

Before buying any supplement online, check for warning signs that may indicate a risky seller or misleading page.

  • Unrealistic promises or guaranteed results
  • Claims that a supplement treats or cures a medical condition
  • Fake “official” pages with no clear company details
  • Marketplace listings with unclear product origin
  • No visible refund policy or confusing return terms
  • Missing ingredient details or unclear label information
  • Countdown timers or pressure tactics with no real explanation
  • Prices that look too low compared with the official seller
