Does matcha tea contain lead?

Yes. The tea plant absorbs lead from soil and air. Because matcha is the whole leaf ground into powder and whisked into water, you consume nearly all the lead in the leaf rather than the small fraction that leaches into a brewed cup. Levels vary widely by brand, origin, and soil quality.

What is the lead content in matcha?

Typical matcha lead content ranges from roughly 0.04 to 0.2 mg/kg (40 to 200 ppb) in published COA data, though some brands test higher. At a standard 2g serving, 0.04 mg/kg delivers approximately 0.08 micrograms of lead, well below California's 0.5 microgram per day Prop 65 threshold.

Is lead in matcha dangerous?

At typical consumption levels (1 to 2 servings per day) from quality brands with published COAs, lead exposure from matcha is generally well below safety limits. Risk rises with heavy daily consumption. The most cautious guidance suggests pregnant women and children prefer steeped tea. This is general information, not medical advice.

Which matcha has the lowest lead?

Brands that publish per-batch third-party COAs with specific lead values in mg/kg or ppb from a named, accredited lab are the most transparent. Steady Matcha publishes its full batch COA at /testing once results are received from the lab.

Does organic matcha have less lead?

Not necessarily. Organic certification means no synthetic pesticides, but lead comes from soil and air, not pesticide application. You need a separate heavy metals COA regardless of organic status.

Is Japanese matcha lower in lead than Chinese matcha?

Generally yes. Japanese agricultural regulations are stricter and soil profiles in regions like Uji are cleaner. But always verify with third-party lab data, since origin claims are easy to fake.

Lead in Matcha: What the Lab Data Actually Shows

Q: Does matcha have lead?

Yes, almost all matcha contains measurable lead at sensitive detection levels. Because you consume the whole ground leaf, matcha carries more lead exposure than steeped green tea. At typical consumption levels (1 to 2 servings per day) from quality brands with published COAs, exposure is generally well below safety limits. This is general information, not medical advice.

Does matcha have lead in it?

Yes. Matcha contains measurable lead in almost every tested sample, because the tea plant absorbs lead from soil and air through its roots and leaves. Unlike brewed tea (where leaves are discarded and most lead stays in the leaf), matcha involves consuming the entire ground leaf. This means your lead exposure from matcha is higher than from an equivalent amount of steeped green tea.

A 2023 Consumer Reports analysis found detectable lead in several of 29 matcha and green tea products tested. Independent testing by Lead Safe Mama (Tamara Rubin) using ICP-MS analysis found lead in every matcha product she tested across 2024 and 2025. The amounts vary widely by brand and origin.

How much lead is in matcha, and is it dangerous?

At a standard 2g serving, a matcha with 0.04 mg/kg lead would deliver approximately 0.08 micrograms of lead total. California's Prop 65 sets a Maximum Allowable Dose Level (MADL) for lead at 0.5 micrograms per day, one of the strictest benchmarks in existence. So a typical quality serving sits well below even that strict threshold.

The exception that matters: this is per serving. If you drink three or more servings per day, cumulative exposure climbs toward the Prop 65 figure, and brand choice matters more. The most conservative guidance suggests pregnant women and children prefer steeped green tea over matcha, since brewing leaves most of the lead behind in the discarded leaf. This is general information, not medical advice.

How to find matcha with low lead content

The only reliable way to know the lead content of your matcha is a Certificate of Analysis (COA) from an independent, accredited third-party lab showing specific numeric values, not just pass/fail. Look for three things: the actual lead result in mg/kg or ppb for the most recent batch; the testing lab name and its accreditation; and the lab's limit of detection (so a non-detect result actually means something).

Japanese matcha from regions like Uji generally shows lower lead levels than Chinese-grown matcha, due to stricter agricultural regulations and cleaner soil profiles. But origin claims are easy to fake. Always verify with third-party lab data.
