Heavy Metals in Cocoa Powder: Are You Safe? (Lab-Tested)
Heavy metals in cocoa powder — chiefly cadmium (Cd) and lead (Pb) — are a real but manageable concern. They can enter cocoa naturally from soil or through contamination during processing. The good news: with a little label-reading and a brand that publishes third-party lab results, you can enjoy cocoa safely. Here's exactly what to know, what's considered safe, and how to choose a tested, low-heavy-metal cocoa powder.
Common heavy metals found in cocoa
Cadmium (Cd)
Cadmium occurs naturally in soils and is absorbed efficiently through the cacao tree's roots. Levels vary by soil composition, geographic origin, elevation, agricultural practice, and bean variety — cocoa from some Latin American regions can show higher concentrations.
Lead (Pb)
Lead comes less from soil uptake and more from external contamination: airborne dust during drying, transport, storage, and contact with processing equipment. It tends to settle on the bean surface during handling.
Is cocoa powder with heavy metals dangerous?
In moderation, quality cocoa is considered safe for healthy adults. Risk comes from cumulative, long-term over-exposure, not an occasional serving. Cadmium can accumulate in the kidneys and bones over time, while lead affects the nervous system — which is why children and pregnant women should be especially careful. The practical answer is simple: choose tested cocoa and enjoy it in normal amounts.
How much heavy metal is actually safe?
There's no single U.S. federal limit for cocoa powder. Two common benchmarks:
- California Prop 65: 0.5 µg lead and 4.1 µg cadmium per day.
- European Union: caps cadmium in cocoa powder at 0.60 mg/kg by concentration.
A genuinely "safe" cocoa powder is one whose published results sit comfortably below these levels — not one that merely prints "pure" or "natural" on the front.
How Grevista keeps heavy metals low — our published lab results
We don't ask you to take "heavy-metal-free" on faith. Grevista cocoa is single-origin Trinitario cacao from Vietnam, non-alkalized, and tested by an ISO/IEC 17025-accredited laboratory. Our results:
Cadmium: 0.081 mg/kg — about 13% of the EU limit (0.60 mg/kg).
Lead, arsenic, and mercury: not detected.
See the full report on our Lab Results & Awards page, and the supporting award certificate and testing documents. High-elevation, single-origin cacao plus minimal (non-alkalized) processing is what keeps our numbers low while preserving natural flavanols.
How to choose a heavy-metal-tested cocoa powder
| Look for | Why it matters |
|---|---|
| Third-party lab results (published) | Independent numbers beat marketing words |
| Single-origin | Traceable soil & farming, not blended lots |
| Non-alkalized (natural) | Less processing; keeps more flavanols |
| Transparent brand | Real transparency is public, not "on request" |

Frequently asked questions
Is there a 100% heavy-metal-free cocoa powder?
Not literally — all cocoa contains trace amounts from soil. Aim for one tested and proven low, with published results below EU/Prop 65 levels.
Does cacao have fewer heavy metals than cocoa?
Not automatically. "Cacao" vs "cocoa" describes processing, not safety. What matters is origin, elevation, and testing.
How much cocoa powder is safe per day?
For healthy adults, 1–2 normal servings a day is widely considered fine. Moderation plus a tested brand is the key.
How can I verify a brand's claim?
Ask for a recent third-party lab report showing cadmium and lead figures. Grevista publishes ours on the Lab Results page.
