The Supplement Blacklist:
27 Popular Products That Failed Testing
You've been lied to. These "bestsellers" failed third-party verification for purity, bioavailability, or clinical evidence.
Download our free report before you waste another dollar on supplements that don't work.
The Supplement Industry Has a Dirty Secret
You walk into a store. You see a supplement with thousands of 5-star reviews. The label promises "clinically proven results." Top 10 rankings on every site.
You buy it. Nothing happens.
Here's why: Most supplement reviews are bought. Rankings are paid for. Third-party testing? Completely optional.
The Truth Behind "Best Sellers"
- ✗ Heavy metal contamination found in "top-rated" products
- ✗ Label claims off by 50%+ in actual testing
- ✗ Wrong forms of ingredients that your body can't absorb
- ✗ Zero clinical evidence for the actual product formulation
We analyzed third-party testing data from labs like ChromaDex, Niagen Bioscience, and ProHealth Longevity using our B.I.S.P. verification system.
The results? 27 popular supplements failed verification. All of them are still bestsellers.

Frequently Asked Questions
What is the Supplement Blacklist?
The Supplement Blacklist is our free report documenting 27 popular supplements that failed our B.I.S.P. (Bio-Purity, Bio-Activation, Bio-Outcome Proof) verification system. These products failed due to contamination, false label claims, poor bioavailability, or lack of clinical evidence.
How did you identify these supplements?
We analyzed third-party testing data from independent labs including ChromaDex, Niagen Bioscience, and ProHealth Longevity. These studies tested dozens of popular supplements for purity, label accuracy, and content verification. We applied our B.I.S.P. framework to evaluate the results. Learn more about B.I.S.P.
Why are these supplements still being sold?
The supplement industry is largely self-regulated. While the FDA oversees safety, they don't verify effectiveness or quality before products reach market. Many popular supplements rely on marketing rather than evidence.
Is the Blacklist really free?
Yes, completely free. No credit card required. We believe this information should be accessible to everyone. We may send you occasional emails about new research and verified supplements, but you can unsubscribe anytime.
Can I trust your testing?
Unlike most review sites, we don't accept paid placements or sponsored rankings. Our testing is conducted by independent third-party labs, and we document all methodology publicly. Read our about page to learn about our commitment to truth over hype.
