Back to the Cocoa Powder Guide
No cocoa powder can honestly promise zero heavy metals, because cacao trees pull small amounts of cadmium from the soil and lead can settle on beans while they dry. What a good cocoa can show you is a level so low that a lab cannot detect it, which is as close to zero as testing can measure. So when you search for “heavy metal free cocoa powder” or a cocoa powder with no heavy metals, the useful question is not “is it zero?” but “how low is it, and can the brand prove it?”
This guide explains why zero is not possible, what “heavy metal free” really means on a label, how close to zero a cocoa can get, and how to check it yourself in two minutes.
Why can’t cocoa powder be completely heavy metal free?
Cadmium and lead occur naturally in the earth’s crust, and human activity adds more. Cacao trees take up cadmium through their roots, so beans from some soils carry more of it than others. Lead works differently: it mostly lands on the outside of the beans as dust while they ferment and dry in the open air, which is why careful drying and cleaning matter.
The U.S. Food and Drug Administration describes the same reality in its Closer to Zero program, which focuses on foods for babies and young children: foods can absorb trace amounts of heavy metals from the environments where they are grown, the agency acts when a level makes a food unsafe, and its goal is to progressively drive levels down over time. Organic farming does not change this either, since organic crops take up metals from the soil just like conventional ones. For cocoa, that means the honest target is “as close to zero as possible”, not “zero”.
What does “heavy metal free” really mean on a label?
| Claim you might see | What it can honestly mean | What to look for |
|---|---|---|
| “Heavy metal free” or “zero heavy metals” | Usually: below the lab’s detection or quantification limit | A lab report showing the limit (LOQ) for each metal |
| “Tested for heavy metals” | At least one sample was tested | The report date and results in mg/kg |
| “Not detected (ND)” | Below the limit printed on the report | The LOQ value, so you know how low “not detected” goes |
| “Below the EU limit” | Cadmium under 0.60 mg/kg | The actual number, since 0.55 and 0.05 mg/kg are both “below the limit” |
“Not detected” is only as strong as the limit behind it. A result of “ND” with a limit of 0.015 mg/kg tells you far more than “ND” with a limit of 0.5 mg/kg. Our guide on how to read a cocoa powder lab report walks through every line.
How close to zero can cocoa powder get?
Here is what “near zero” looks like in practice, using the October 2026 independent lab report for the cocoa Grevista distributes. All four heavy metals came back below the lab’s quantification limits:
| Metal | Result (lab limit, LOQ) | For comparison |
|---|---|---|
| Cadmium | Not detected (below 0.015 mg/kg) | EU limit for cocoa powder: 0.60 mg/kg, at least 40 times higher |
| Lead | Not detected (below 0.05 mg/kg) | No EU limit set for cocoa powder |
| Arsenic | Not detected (below 0.03 mg/kg) | No EU limit set for cocoa powder |
| Mercury | Not detected (below 0.02 mg/kg) | No EU limit set for cocoa powder |
In everyday terms, two tablespoons of a cocoa below 0.015 mg/kg cadmium carry less than 0.17 micrograms of cadmium, under 5% of California’s Proposition 65 daily reference level of 4.1 micrograms. That is what “approaching zero” means: not a promise of nothing, but a level too small for a modern lab to measure. The full report is on our lab results page, and the wider picture of limits and recent tests is in heavy metals in cocoa powder.
How do you find a cocoa powder with the lowest heavy metals?
- Ask for the lab report, not the slogan. Look for results in mg/kg for cadmium and lead, the test date and the quantification limit.
- Check the limit behind “not detected”. The lower the LOQ, the more meaningful the result.
- Look at the origin. Cadmium depends on soil, so a named, single origin with published results tells you more than a blend from unnamed sources.
- Do not rely on “organic” or “Dutch-process” alone. Neither removes metals already in the beans.
- Compare per serving. Multiply the mg/kg result by the grams you actually use; a tablespoon of cocoa is about 5 to 6 g.

Frequently asked questions
Is there a cocoa or cacao powder with no heavy metals?
Not in the literal sense of zero. The best you can find is cacao or cocoa powder with heavy metals below the detection limit of an independent lab, backed by a published report.
Is organic cocoa powder lower in heavy metals?
Not automatically. Organic rules cover pesticides and fertilizers, not soil metals, and organic cacao takes up cadmium from the soil like any other cacao.
Does Dutch processing remove heavy metals?
No. Alkalizing changes color and flavor; it does not remove cadmium or lead from the cocoa solids.
How much cocoa powder a day is reasonable?
It depends on the cocoa’s tested levels. Our guide to how much cocoa powder per day shows how to work it out from a lab result.
Which cocoa powders are tested for heavy metals?
Many brands say “tested”, but the ones you can check publish the full report: the lab’s name, the test date, a result for each metal in mg/kg and the quantification limit. Grevista publishes its full VietLabs report on the lab results page. How the testing works is explained in how cocoa powder is tested for heavy metals.
What is the best cocoa powder without heavy metals?
The closest you can get is a cocoa with every metal below the lab’s limits, a low LOQ and a named origin. Our guide to choosing the best cacao powder walks through the checks.
