A Look Inside Hiya’s Testing for Heavy Metals

Hiya is a kid’s vitamin brand founded by two dads who set out to create a clean kid’s vitamin without sugar or any of the questionable ingredients found in so many of the kid’s vitamin brands on the market today. One standout aspect of the brand is their rigorous testing protocols that exceed industry standards — let’s take a closer look.


Today, many kid’s vitamins on the market do not conduct third-party tests (meaning using an outside, independent lab) for heavy metals, and very few brands test every batch of product. Hiya utilizes third-party labs to test for heavy metals, such as lead, arsenic, mercury, and cadmium. Hiya is a leader in the industry, testing each and every batch of products for heavy metals using scientifically validated testing methods for testing. We break it down for you below.

Does Hiya Test for Heavy Metals Like Lead, Arsenic and Cadmium?

Hiya third-party tests every batch of its product for heavy metals, including lead, mercury, chromium, arsenic, and cadmium.

 

Heavy metals are naturally occurring elements found in soil, water and air. This means practically all of the healthiest fruits and vegetables (e.g., spinach, carrots, kale, etc) naturally include some degree of metals. So, if you’re eating foods that are plant-based, your food will almost certainly include some metals.

 

Given their prevalence, thorough testing is important to ensure any amounts are always considered safe, especially for children’s products. Hiya’s stringent testing protocols ensure that every product is tested by an ISO/IEC-accredited lab. This level of diligence per batch is not required in the industry but is part of what sets Hiya as a leader in the sector.

 

Furthermore, these labs use scientifically validated testing methods: for example, the most widely accepted approach for testing elements, whether they are heavy metals such as lead, arsenic, cadmium, and mercury, or other elements such as iron, calcium, or selenium is a technique known as coupled plasma mass spectroscopy (“ICP-MS”). It’s critical to test in a clean, FDA-compliant lab.

How Often Does Hiya Conduct Heavy Metal Testing?

Hiya conducts heavy metal testing on every batch of every product. Unlike many companies that rely on random-batch testing, Hiya ensures that each lot of product is thoroughly tested for substances like lead at multiple points along the supply chain.

Who Performs the Heavy Metal Testing for Hiya?

Independent, reputable laboratories perform Hiya’s testing. These labs are accredited under ISO/IEC 17025, the globally recognized gold standard for laboratory testing. The labs undergo regular audits and must meet the evolving standards set by regulatory agencies.

Is Hiya Compliant With California Prop 65?

Yes, Hiya is fully compliant with California Proposition 65, which sets the most stringent nationwide rules for product safety. Prop 65, also known as the Safe Drinking Water and Toxic Enforcement Act, protects consumers from potentially harmful chemicals by requiring businesses to disclose significant exposures to heavy metals.

 

Hiya tests every batch of vitamins for contaminants of concern, like lead and arsenic. This ensures that even trace amounts are always below acceptable limits or absent. By adhering to these guidelines, Hiya goes beyond federal regulations to provide an extra layer of safety for your children.

 

This compliance is part of Hiya’s larger mission to provide safe, high-quality products for children. They routinely test their products to meet the strictest standards in the nation. It’s why so many parents feel comfortable giving Hiya to their kids daily.

Are Hiya’s Manufacturing Facilities GMP-Certified?

Hiya works exclusively with GMP-certified (Good Manufacturing Practices) facilities to ensure that every step of their production process meets the highest standards of safety and quality. GMP certification is awarded to facilities that meet all regulatory requirements for manufacturing, packaging, labeling, or holding of dietary supplements as defined in FDA 21 CFR 111. These regulations address all aspects of quality control, including cleanliness, equipment maintenance, staff training, and quality control procedures.

 

The manufacturers maintain current GMP practices. They are regularly inspected and audited by third-party auditors and the FDA. This ensures that the vitamins are produced in environments where every aspect of production is carefully monitored and controlled.

Are Hiya’s Bottles Safe From Lead?

Yes. While many vitamin bottles are made of plastic, Hiya’s bottles are made from borosilicate glass. Borosilicate glass is non-toxic and free from harmful chemicals like BPA or lead, making it a safe option for storage. It also protects vitamins from environmental factors that could degrade them or compromise shelf life. Using these glass bottles ensures the long-term potency and quality of the vitamins inside.

 

Hiya tests their bottles through reputable third-party labs to ensure safety. Hiya uses a “water-based” paint (distinct from solvent-based or lead-based paint), which not only mitigates health concerns but is also better for the environment.

 

Their bottles are then tested (interior and exterior) by qualified labs using scientifically validated methods (like ICP-OES), including testing for contaminants like lead and cadmium. Hiya follows Consumer Product Safety Commission-approved methods for testing and consistently meets all regulatory standards for bottle testing to ensure the safety of bottles.

How Can I Be Sure Hiya’s Products Are Safe for My Child?

At Hiya, ensuring the safety of their products is an ongoing, rigorous process built into every stage of production. From raw materials arriving at their GMP-certified facilities to the final packaging, each ingredient is tested and inspected to ensure it meets their high standards — ingredients or components that fail testing at any point of the process are rejected. Hiya conducts additional quality checks, such as visual inspections and further contaminant testing when necessary, to ensure safety for their customers.

 

Parents who choose Hiya often share how Hiya’s vitamins not only support their children’s health but also provide the peace of mind that comes with knowing they take these extra precautions. Their feedback serves as a reminder that safety, transparency and trust are central to everything Hiya does. By choosing Hiya, you’re choosing a brand that proves their commitment to safety with every test, inspection and batch.
