The main Hiya vitamins lawsuit on the public docket is Chew CPG, Inc. v. Hiya Health Products, LLC, a contract dispute filed in July 2025 by a former product-development partner and now pending in federal court in Massachusetts. Hiya has not been sued over the heavy metals question that drew attention to the brand in 2024, but that controversy and a steady stream of subscription-billing complaints are what most people are asking about when they search for legal trouble at the company.
The Chew CPG Contract Lawsuit
Chew CPG, Inc., a Boston-based food and beverage product-development firm, sued Hiya Health Products in Massachusetts Superior Court for Suffolk County in July 2025. The complaint is styled as a contract dispute. Chew CPG opened the case with an ex parte motion for trustee process attachment, a mechanism used to freeze a defendant’s assets held by third parties while a claim is pending. The named trustee defendants are UBS Financial Services Inc. and Bank of America, NA.1Justia Dockets. Chew CPG, Inc. v. Hiya Health Products, LLC et al
Hiya removed the case to the U.S. District Court for the District of Massachusetts in August 2025, where it was docketed as 1:2025cv12344 and assigned to Magistrate Judge M. Page Kelley. In September 2025, Hiya moved to dismiss for failure to state a claim and told the court that the asset-freeze motion is “largely moot and resolved” following assurances it gave Chew CPG about the availability of funds. The court directed the parties to file a joint status report on that point. As of the last docket activity in October 2025, the case remained pending, with Chew CPG’s opposition to the motion to dismiss on file.1Justia Dockets. Chew CPG, Inc. v.

Heavy Metals Testing Controversy
In September 2024, consumer safety advocate Tamara Rubin, who publishes the Lead Safe Mama blog, released lab results reporting that Hiya Kids Daily Multivitamins tested positive for lead, cadmium, and arsenic. The testing was performed by SimpleLab, and results were compared to the health-protective action levels proposed in the Baby Food Safety Act of 2021, a bill that was never enacted. Rubin acknowledged that the detected levels were not illegal under current regulations but noted that federal agencies agree there is no safe level of lead exposure for children.2Tamara Rubin / Lead Safe Mama. Hiya Kids Daily Multivitamins Test Positive for Lead, Cadmium, Arsenic
Hiya disputed the findings. The company said it tests every batch through independent FDA-certified and ISO-certified laboratories, identifying Kappa Labs and PDA Laboratories Inc. as its testing partners, and stated its heavy metal levels fall “well below federal standards and the most stringent statewide standards,” including California’s Proposition 65 limits. Hiya also questioned the credibility of the lab used by Lead Safe Mama, saying it could not confirm whether that facility was FDA-registered or ISO-certified.3Tamara Rubin / Lead Safe Mama.

Rubin followed up by criticizing the lab reports Hiya was sending to concerned customers, arguing that the reports did not specify detection thresholds or units of measurement. She noted that many supplement companies test only down to 1 to 5 parts per million, less sensitive than the 10 parts per billion threshold her lab used, and that Hiya’s samples were “client-sampled,” meaning the manufacturer chose what to submit rather than an independent party pulling product from retail shelves.4Tamara Rubin / Lead Safe Mama.

What Hiya Says About Its Testing Now
In February 2025, Hiya earned Clean Label Project certification, announced publicly in May 2025. The certification process involves the Clean Label Project independently buying products off retail shelves and submitting them to ISO-accredited labs for screening against heavy metals, more than 300 pesticides, and plasticizers such as BPA and phthalates. To keep the certification, Hiya must submit to unannounced random annual testing. The Kids Daily Multivitamin, Probiotic, Bedtime Essentials, Iron+, and Immune products all received the Clean Label Project Purity Award.5Nutraceuticals World. Kids Multivitamin Brand Hiya Receives Clean Label Project Certification Hiya’s published protocol says it uses Inductively Coupled Plasma Mass Spectroscopy at ISO/IEC 17025-accredited labs on every batch, with detection limits as low as 0.28 parts per billion for mercury and 0.33 parts per billion for cadmium, measured against California Proposition 65 limits and U.S. Pharmacopeia standards.6Hiya Health.

The Regulatory Boundary
No federal law sets specific permissible levels of lead, cadmium, or arsenic in dietary supplements or children’s vitamins. The FDA’s “Closer to Zero” initiative, launched in 2021, aims to reduce childhood exposure but relies on an iterative process to develop action levels. As of January 2025, the agency had issued final guidance on lead action levels in processed foods for babies and young children; arsenic and cadmium action levels remain in development. Manufacturers are responsible for implementing preventive controls, and the FDA may take enforcement action if it finds a product unsafe.7U.S. Food and Drug Administration.

Subscription Billing Complaints
The larger consumer-facing legal issue at Hiya is billing. As of mid-2026, the Better Business Bureau lists 160 complaints against Hiya Health Products LLC filed over the preceding three years, with 52 closed in the last twelve months. The company still holds an A+ rating and is BBB-accredited.9Better Business Bureau. Hiya Health Products LLC – Complaints
The recurring themes in the complaints:
- Customers say they were enrolled in a monthly recurring plan after placing what they thought was a one-time order.
- Customers describe cancellation as difficult, citing broken website links, no phone support, and a requirement to cancel by email or text.
- Complaints allege inadequate notice before cards were charged for upcoming shipments, making it hard to stop an order in time.
- Some parents reported their children refused the vitamins or raised concerns about tablet size and choking risk.
Of the 160 complaints, 60 are marked resolved to the consumer’s satisfaction and 100 are listed as answered but not confirmed resolved. In its responses, Hiya generally apologizes, confirms the subscription is canceled, and often issues a full or partial refund. The company explains that its model is a monthly membership and that once an order enters processing or shipping, its system cannot cancel it. Hiya does not provide prepaid return shipping labels, asking customers to return products at their own expense.10Better Business Bureau. Hiya Health Products LLC – Complaints Page 8
No consumer class action over the billing practices appears in the record reviewed here. If you want to stop charges, the practical takeaway from the complaint pattern is to cancel well before your next ship date and to keep written proof of the cancellation request, since phone cancellation is not offered.
