No named laboratory or lot-specific certificate was found for this exact product. A related brand page repeats a testing claim but names no issuer; its UPC is not published. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.

Micro Ingredients Myo-Inositol & D-Chiro Inositol Powder…
Checked against public sources between July 21 and August 31, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Package and trademark records name different responsible entities. The package says distributed by: Micro Ingredients, 4382 Mission Blvd, Montclair, CA 91763. USPTO names DPL Trading, Inc. as the exact wordmark owner. …
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 82 to 173 between August 21, 2025 and August 30, 2026. The largest rise inside any single 30-day window was about 20, so the count moved in steps rather than in one burst.
