Our NervoVive review methodology
- Identify the current vendor-controlled pages before using third-party claims.
- Separate vendor claims, observable purchase terms and independent evidence.
- Prefer FDA, NIH/NCCIH/NIDDK/NINDS, PubMed and peer-reviewed systematic reviews for health claims.
- Never invent customer reviews, star ratings, doctor endorsements or “verified” tests we did not perform.
- Treat affiliate commissions as a conflict to disclose, not something to hide.
- Update buyer-intent pages when price, refund, shipping or formula changes.

How affiliate revenue affects the site
We may earn a commission if a reader buys through our links. The commission does not change the checkout price and does not authorize us to invent positive findings. We use rel="sponsored nofollow" on affiliate links and disclose our relationship prominently.
Update protocol
High-intent pages such as price, shipping, refund and where-to-buy should be re-checked more often than evergreen ingredient pages. Our build includes a “last reviewed” data point in the footer and a launch checklist reminding the site owner to verify live purchase terms before deployment.
