Public contextWho is behind it?
Registered owner records: NUTRABIOCOM, INC. · NutraBio Labs, Inc.
The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
USPTO returned multiple live supplement-class records for the exact brand wordmark: NUTRABIOCOM, INC., NutraBio Labs, Inc.. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Reviews rose from 9 to 16 between March 13 and May 27, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 9 to 16 between March 13 and May 27, 2026. The largest rise inside any single 30-day window was about 8, so the count moved in steps rather than in one burst.
These are the USPTO records behind the brand name. We show them all rather than choosing one by similarity.

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
Prices and stock are point-in-time observations. Related pages are never used as product evidence. No affiliate links; LookCloser earns nothing from these sellers.
