2026-07-31 FDA Warning Letter: H2 BEV, LLC and H2 RENU, INC Cited for Acidified Foods/Emergency Permit Control/Adulterated/Misbranded
Letter issued · posted to fda.gov .
Subject as published: Acidified Foods/Emergency Permit Control/Adulterated/Misbranded
TL;DR
Key takeaway: The FDA issued a warning letter to H2 BEV, LLC and H2 RENU, INC (Owner: Kurt H Ruppman, Plano, TX) on July 31, 2026 (CMS #730567) following inspections from December 2025 through January 2026 regarding violations of acidified foods regulations (21 CFR Parts 108 and 114). The FDA determined the company's acidified, non-carbonated, hydrogen gas-infused beverages are adulterated under the Food, Drug, and Cosmetic Act due to preparation under insanitary conditions; the company failed to register as a food canning establishment, file scheduled process information for any products, and maintain adequate quality control and production records. The FDA also found that H2 RENU Oncology Care Beverage and Hydro Shot Hydrogen Beverages are unapproved drugs based on disease-related claims made on the company's websites.
Argus analysis
# FDA Warning Letter Analysis: H2 BEV, LLC and H2 RENU, INC
## Company and Findings
H2 BEV, LLC and H2 RENU, INC, owned by Kurt H Ruppman and located in Plano, Texas, manufacture acidified hydrogen-infused beverages including Hydro Shot and H2 RENU Oncology Care Beverage products. FDA's Human Foods Program conducted inspections from December 2025 through January 2026 and identified serious violations of acidified foods regulations. The agency determined the products are adulterated because they were prepared under insanitary conditions that may have caused contamination or rendered them injurious to health.
## Regulatory Citations
The violations involve 21 CFR Part 108 (Emergency Permit Control) and 21 CFR Part 114 (Acidified Foods). Specific deficiencies include failure to register as a food canning establishment (21 CFR 108.25(c)(1)), failure to file scheduled process information (21 CFR 108.25(c)(2)), inadequate quality control procedures (21 CFR 114.80(a)), and insufficient pH documentation (21 CFR 114.80(a)(2)). These regulations typically require processors to maintain precise heat-treatment and pH records to prevent pathogenic growth in low-acid beverages. Additionally, FDA determined products marketed with disease-treatment claims are unapproved drugs under section 201(g)(1)(B) of the Federal Food, Drug, and Cosmetic Act.
## Timeline and Industry Outlook
The warning letter was issued July 31, 2026, following an inadequate March 10, 2026 response that included only employee training registration without addressing core compliance gaps. As of the letter date, the company had not registered or filed required process documentation. Peer compliance officers in beverage manufacturing should monitor whether H2 BEV takes corrective action including facility registration, scheduled process filing, retroactive record documentation, and removal of drug claims from marketing materials. Continued non-compliance may result in seizure or injunction proceedings.
Severity context
Critical severity. Typically reserved for data integrity, sterile-product CGMP, or repeat violations — matters that historically precede injunctions, consent decrees, or import alerts.
Regulatory background
Labeling letters cite 21 USC 343 (food), 21 USC 352 (drugs), or 21 USC 352 (devices). Most are resolved by SKU-level copy revision within the 15-business-day response window.
What peer compliance teams typically do next
Most compliance officers at peer companies use a Warning Letter against a named entity as a checklist for their own CAPA program. Common steps: pull the verbatim FDA letter; map each cited 21 CFR section against the team’s SOP library; confirm CAPA coverage; brief the QMR (Quality Management Review) on whether the cited subject matter is in scope for the next internal audit. The 15-business-day response window applies to the cited entity, not to peers — but a documented internal review against the cited subjects is what regulators expect to see if a peer is later inspected on the same topic.
Excerpt from the FDA Warning Letter (public domain, 17 USC §105)
WARNING LETTER H2 BEV, LLC and H2 RENU, INC MARCS-CMS 730567 — July 31, 2026 More Warning Letters Warning Letters About Warning and Close-Out Letters Delivery Method: VIA ELECTRONIC DELIVERY Product: Food & Beverages Recipient: Recipient Name Mr. Kurt H Ruppman Recipient Title Owner H2 BEV, LLC and H2 RENU, INC 912 Presidio Ct Allen , TX 75013 United States kurtsr@h2bev.com Issuing Office: Human Foods Program United States July 31, 2026 WARNING LETTER CMS #730567 Dear Mr. Ruppman: The United States Food and Drug Administration (FDA) conducted inspections of your acidified foods facility, which includes H2 BEV, LLC and H2 RENU, INC, located at 1601 Summit Ave, Ste 100, Plano, TX 75074-8109 US, on December 3, 2025, through January 12, 2026, and January 6 through 12, 2026, respectively. The inspections revealed serious violations of the Emergency Permit Control regulation, Title 21, Code of Federal Regulations, Part 108 (21 CFR Part 108) and the Acidified Foods regulation (21 CFR Part 114). As an acidified food processor, you are required to comply with the Food, Drug, and Cosmetic Act (the Act) and the federal regulations relating to the processing of acidified foods and current good manufacturing practices. These regulations are described in 21 CFR Part 108, Emergency Permit Control and in 21 CFR Part 114, Acidified Foods. The Emergency Permit Control regulation was issued, in part, pursuant to section 404 of the Act [21 U.S.C. § 344]. A temporary emergency permit may be required for acidified foods whenever a processor has failed to fulfill the requirements of 21 CFR Part 108.25, including registration and filing of process information, and the mandatory requirements of 21 CFR Part 114. Based on FDA’s inspectional findings, we have determined your acidified, non-carbonated, hydrogen gas-infused beverages are adulterated within the meaning of section 402(a)(4) of the Act [21 U.S.C. § 342(a)(4)] in that they were prepared, packed, or held under insanitary conditions whereby they may have become contaminated with filth, or may have been rendered injurious to health. You can find the Act and FDA’s regulations through links in FDA’s homepage at www.fda.gov. At the conclusion of the inspections, a Form FDA 483 (FDA 483), Inspectional Observations, was issued listing the deviations found at your facility. We acknowledge your response received via email on March 10, 2026, which included an employee registration to a Better Process Control School for acidified foods. However, our evaluation of the documentation revealed that the response was not adequate, as further described in this letter. Furthermore, we have reviewed the claims on your websites, www.h2renu.com and www.h2bev.com, and established that your H2 RENU Oncology Care Beverage product and Hydro Shot Hydrogen Beverage Strawberry, Lemon Lime, and Orange flavored products are drugs under section 201(g)(1)(B) of the Act [21 U.S.C. 321(g)(1)(B)] because they are intended for use in the cure, mitiga…
