Natural Factors

Our Privilege, Our Passion

Today, Natural Factors is one of the largest manufacturers of nutritional products in North America. But our origins reach back to the 1950s, and right from day one, we’ve always been fully committed to making products right. We are not a public company with shareholders to impress. Instead, we care about impressing you.

ISURA™ Third Party Product Verification And Certification

We chose ISURA to certify our products because they use state-of-the-art equipment, such as real-time PCR (polymerase chain reaction) analysis, to identify genetically modified or genetically engineered organisms. They also use mass spectrometry to test for over 600 pesticides, solvents, heavy metals, and other contaminants. The ISURA seal of approval is your guarantee that our products are non-GMO, safe, pure, and potent.
