Quality Matters

If it’s going in your body, there should be no question about the contents or quality. That’s why we spend millions of dollars each year ensuring our products are pure, potent, and exactly what you ordered. Our goal is to make supplements we take ourselves, and we have some damn high standards.

The  Facilities

Our Labs Are ISO 17025:2017 Certified. That’s not just technical nonsense – it’s important. An ISO accreditation is an international standard for lab processes. Getting verified involves a third party auditor, facility scrutiny, and process analysis. Basically, it means we care about our products and our customers. A lot. 

We’re GMP Certified.

The Process

GMP stands for Good Manufacturing Practice, and it ensures that every product we make has documentation that it has followed stringent quality standards.

Triple Tested Supplements

Before every product gets to you, it has been lab tested three times. Once by our ingredient suppliers, once by our own labs at intake, and once before getting bottled. But it doesn’t stop there. Here’s how we test:

  1. No Skip Lot Testing. We test every batch, every time.
  2. Composite Testing. This means we test every level of our intake drums to ensure product integrity throughout.
  3. Identity, Purity, Potency. We test each ingredient and product to make sure it’s authentic, clean, and active.
