What is Regenerative Agriculture?
Tested for what parents care about most.
Heavy Metal Testing
We test our products for heavy metals and share results because parents deserve clarity, not confusion. Our goal is to reduce exposure wherever possible and make purity something families can see.
Heavy Metals & Batch Testing
Transparency parents can actually use.
Heavy metals like lead, arsenic, cadmium, and mercury can occur naturally in soil, water, and the environment, which means no farmed food can promise absolute zero. But that does not mean parents should be left in the dark.
At White Leaf, we believe the right response is testing, transparency, and continuous improvement.
Each batch of our products is tested through independent third-party laboratories for heavy metals of concern. We publish results so parents can see the data behind our standards and make informed choices for their families.
Our approach begins with sourcing from farms that prioritize healthy soil and responsible growing practices. It continues through ingredient selection, testing, monitoring, and public disclosure. Because when it comes to first foods, “trust us” is not enough.
We want parents to understand what was tested, what was found, and why reducing avoidable exposure matters.

Our entire line meets U.S. regulations and goes beyond, guided by the more rigorous standards of the European Union—home to some of the world’s strictest agricultural practices—and the Clean Label Project’s benchmarks for heavy metals. When no official guidance exists, we set our own internal limits to exceed expectations and ensure the highest level of purity in every bite.

What is ppb? What does non-detect mean?
PPB (Parts Per Billion) measures incredibly small concentrations—equivalent to one second in 32 years. That’s the level of precision we use, because even the smallest trace matters when it comes to your family’s health.
