1. Product Procurement & Independence
We purchase evaluation samples independently through standard consumer channels whenever feasible. When manufacturers submit products for clinical audit, they must sign a binding agreement: the sponsor has zero editorial control over the final review score or published findings. Products that fail safety or efficacy benchmarks are reported transparently.
2. The 5 Evaluation Pillars & Scoring Weights
| Pillar | Weight | Testing Criteria |
|---|---|---|
| 1. Pharmacokinetic Bioavailability | 30% | Evaluation of delivery mechanism (sublingual liquid vs. gastric degradation). Absorption speed into cochlear microcirculation. |
| 2. Peer-Reviewed Evidence (PubMed) | 25% | Level of clinical support: double-blind randomized trials, meta-analyses, and dosage titration matching published science. |
| 3. Purity & Manufacturing Safety | 20% | Third-party laboratory Certificates of Analysis (CoA), GMP certification, heavy metal screening, and absence of stimulants. |
| 4. Value & Guarantee Protection | 15% | Cost per day vs. alternatives ($4,000+ hearing aids), transparency of pricing, and minimum 60 to 90-day money-back guarantee. |
| 5. Real Patient Feedback & Safety | 10% | Auditing verified customer experiences, BBB ratings, and monitoring for side effect reports. |
3. Peer-Review & Medical Oversight
No article or review is published without review by at least one board-certified physician (MD) or certified physician assistant (PA-C). Our reviewers check:
- Accuracy of biological terminology and anatomical claims;
- Contraindications with common prescription medications (e.g., blood thinners, cardiac drugs);
- Appropriate contextual disclaimers that guide readers to consult their in-person physician.
4. Biannual Re-testing & Version Updates
Formulations change, new scientific papers are published, and manufacturing lots evolve. Our medical board conducts scheduled reviews every 6 months to ensure our ratings reflect current market reality.
