Natural Factors and ISURA® – A Partnership with a Common Mission

Trust Through Quality: The Natural Factors Difference

We believe supplements should be something that you and your family can truly rely on. That’s why at Natural Factors, our mission has always been to ensure every bottle lives up to its promise of purity, potency, and safety. When you choose our products, you deserve the peace of mind that what’s on the label is exactly what’s inside.

Safeguarding Your Health

From the moment we source our raw materials to the time they reach you, every step is guided by strict quality standards. We test every single batch in our own labs to verify purity and potency. But that’s only the beginning.

Our commitment to quality is proven through independent, third-party testing. We invite outside experts to meticulously check our products, adding an extra layer of transparency and accountability. It’s not just us saying our supplements are safe and effective. An unbiased authority confirms that each product does what it says and is free of contaminants like pesticides, heavy metals, and solvents.

Meet ISURA

ISURA is an independent, non-profit organization specializing in natural health product certification. They operate one of North America’s leading analytical laboratories, using advanced testing methods considered the gold standard in the industry.

The ISURA seal of approval on a Natural Factors product means it has been rigorously verified to be:

· Free from contaminants.

· Non-GMO with one of the strictest thresholds in the world (0.1%).

· Accurately labeled for ingredients and potency.

ISURA tests for over 800 potential contaminants, going above and beyond industry standards.

Why this Matters for You

Whether you’re supporting a specific health concern or simply maintaining your wellness routine, you need to feel confident that what you’re taking is both effective and safe.

At Natural Factors, we share the same mission as ISURA: to ensure every supplement earns your trust. For us, quality isn’t just a claim on a bottle. It’s the foundation of everything we do.

Integrity in Every Bottle

Our founder, Roland Gahler puts it best: "For us, integrity means being able to, and willing to, stand behind every product we produce. Each of us at Natural Factors feels responsible for the quality, purity, and efficacy of our products."

When you choose Natural Factors, you’re not just choosing a supplement. You’re choosing a standard built on science, verified by experts, and guided by unwavering integrity.

Factors Farms®

Ever since our humble beginnings over 60 years ago, we have chosen a path less traveled; a path that showed how much we care for our beautiful planet and the healing ingredients that she so generously provides.

By owning and maintaining our farms we are able to learn how to generate the most nutritious ingredients while respecting the earth’s natural rhythms.

With over 1,000 acres of certified organic farmland in the Okanagan Valley of British Columbia, we grow an astonishing variety of crops for production and research.

From using heirloom, non-GMO seeds to weeding and harvesting by hand, we ensure the greatest possible potency and show our dedication to a responsible, regenerative approach to cultivating the earth.
