Is Umbrella Labs still in business after the FDA warning letter?
At the desk's check on 2026-10-19 the storefront was recorded as on watchlist, with 6 of 8 checks verified. A letter does not close a storefront by itself; the tracker records only what the storefront showed on the check date.
Did Umbrella Labs respond to the FDA?
The file does not record a response. When the agency posts a company's reply or a close-out letter it does so on the same fda.gov page the letter sits on, which is linked from this page; the desk does not paraphrase either.
What does the letter do to the file?
The "no FDA warning letter on record" check is stamped Not verified and the seal is held at C or below for as long as the letter stands in the public record. The other seven checks are read as usual; on this file 6 of 8 are verified.
