At Hiya, we understand that nothing is more important than safety and quality when it comes to your child's health. That's why we are a market leader in implementing comprehensive Quality Assurance and Quality Control (QA/QC) practices that go above and beyond industry standards.

Hiya continuously collaborates with our supply chain partners to build best-practice quality checks and improvements throughout our production process. We test each lot of product at multiple points along the supply chain. This testing includes submitting EVERY batch of every product for contaminant testing, including heavy metals and microbial testing.

Hiya tests for heavy metals, including: lead, mercury, arsenic, and cadmium. When Hiya tests for heavy metals, we test for these contaminants to ensure the safety of our Hiya families.

That is why Hiya partners exclusively with GMP-certified manufacturers who share our commitment to excellence and submit to regular FDA inspections and 3rd party audits such as NSF, UL, and USP to ensure they are operating in compliance with all regulatory standards. All raw materials undergo on-site quality testing. Our finished products are rigorously tested for purity and potency, with detailed Certificates of Analysis (COAs) maintained for every batch.

Every batch and lot of Hiya products undergo third-party testing by independent, reputable labs such as Kappa Laboratories and PDA Laboratories Inc. 

Hiya also conducts visual inspections of all products at our warehouse and performs additional heavy metal testing as needed. Our commitment to safety extends to compliance with California Prop 65, which sets the most stringent nationwide rules for product safety.

At Hiya, we believe in transparency and traceability. Here is a look at a real third-party lab test, performed on Hiya’s products:
