• ✓ Arsenic, mercury, and lead: not detectable.
• ✓ Low-cadmium cacao: 0.15 mg/kg (well below international safety limits).
• ✓ Meets and exceeds EU, FDA, and Codex safety guidelines.

Why heavy-metal testing matters

Cacao trees are natural bio-accumulators, they pull minerals and trace elements from the soil as they grow. That includes beneficial nutrients, but it can also include heavy metals depending on the region, farming practices, and environment. As a result, heavy-metal levels in cacao can vary widely from farm to farm.

Many cacao brands, especially those using mixed-origin or bulk beans, never test for heavy metals. When beans are blended from different farms, seasons, or regions, the final product becomes unpredictable, and consumers have no clear information about what they’re actually drinking.

Cadmium is the most heavily regulated mineral in cacao worldwide, and many Latin American producers struggle to meet EU thresholds due to naturally mineral-rich volcanic soil. Our low cadmium level is a significant quality indicator and makes our cacao compliant with international export standards.

These results tell a deeper story:

• The soil on our partner farm is healthy and uncontaminated.
• The beans are handled cleanly during fermentation and drying.
• Our production process does not introduce contaminants.
• The final product is safe for daily consumption.

At Nantli, we believe premium cacao should come with proof. Heavy-metal testing is part of our commitment to quality, transparency, and respect for the people who drink our cacao.

Our partner farms are fair-trade and use organic practices. Our soils are tested for heavy metals, and we prioritize small-scale, regenerative growers who work closely with the land.

Our most recent heavy-metal test shows no detectable arsenic, mercury, or lead, plus a low cadmium level (0.15 mg/kg), well below international safety limits. This tells us Nantli Cacao is grown using organic practices, even if it may not carry a formal third-party organic certification yet.

Our farms:

• Follow organic methods (no synthetic fertilizers, pesticides, or chemicals).
• Use regenerative, soil-nurturing practices rather than industrial farming.
• Test soils regularly, a core requirement of organic farming.
• Are small-scale and fair-trade, prioritizing ecological balance and community well-being.
• Produce cacao that meets high purity standards, including clean heavy-metal results.

Cacao is naturally rich in magnesium, antioxidants, and theobromine, a gentler stimulant than caffeine, which is why a cup lifts you without the jitters or the crash.

Our cacao is grown with organic practices, fairly sourced, and 100% vegan. It’s produced in an industry-standard facility and tested to ensure it’s free of heavy metals.
