Supplement Lab Testing: Potency, Purity, and Heavy Metals
We provide a wide range of analytical and microbial testing services to ensure the quality and safety of your supplements. We can test your finished product or raw materials.
​
Elevate Your Brand with Uncompromising Quality Control​
​
Protect your brand’s reputation with precision supplement testing services. Our ISO 17025 accredited laboratory delivers the rigorous potency analysis and contaminant screening required to stand out in a crowded market. Whether you are launching a new pre-workout or scaling protein production, we provide the Certificate of Analysis (CoA) you need to prove your commitment to quality and safety.
Heavy Metal Testing: Don't Let Contaminants Weigh You Down
​
Let's face it. Heavy metals like Lead, Arsenic, Cadmium, and Mercury are the ultimate party crashers. They can sneak into your supply chain through soil, water, raw mineral sources, or even processing equipment.
​
At Twin Arbor Labs, we do not guess when it comes to safety. We use ultra-sensitive ICP-MS technology to catch trace-level elemental impurities before they ever make it to a consumer. Whether you are formulating a complex dietary supplement, a new toothpaste, or a cosmetic cream, we provide defensible data using rigorous standards like USP <233> for consumer goods and AOAC 2015.01 for foods.

Passing the Prop 65 Test
If you are selling products in California, Proposition 65 is your biggest regulatory hurdle. Unlike standard concentration limits, Prop 65 focuses on total daily exposure. A failure here is not just a compliance issue; it is a massive brand risk that invites lawsuits.​
