- What it is
- A naturally occurring heavy metal with no known biological function in the human body.
- How it gets into formula
- Trace lead in soil and water is taken up by crops (including rice, oats, and soy) and dairy herds, and can also enter during processing.
- Why it matters for infants
- The CDC and the American Academy of Pediatrics state that no safe blood lead level in children has been identified. Chronic low-level exposure is associated with developmental and learning effects, and infants absorb ingested lead at a higher rate than adults.

The five metals in the data
Heavy metals occur naturally in soil and water, so trace amounts reach nearly all food — including formula ingredients. The question is never "zero or not," it's how much, compared to what's achievable.
How the intake screening score works (DRAFT)
Parents see estimated contaminant intake if a child consumed the same formula over ~1 year, listed against named protective anchors on every formula. This draft replaces cohort “missing = best” ranking. It does notuse LeaveDuration / half-life / retained / body-burden math (Sol 5.6 reject). Score math stays draft until James reviews — do not treat live Railway as this until merged.
- Feeding assumptions (visible in UI): default 24 fl oz/day prepared formula × 365 days, at 4.4 g powder / fl oz (≈105.6 g/day). Editable volume on Detail. Methodological default aligned with CR-style scenarios — not every infant’s intake.
- Always list year-window intake for Lead, Inorganic Arsenic, Cadmium, and Aluminum. Missing metals show as not tested, never as a purity bonus.
- Named anchors only (citeable):
- Lead — CA OEHHA MADL 0.5 µg/day
- Cadmium — CA OEHHA MADL 4.1 µg/day
- Inorganic arsenic — EPA RfD 0.06 µg/kg-bw/day at disclosed 6.1 kg infant
- Aluminum — FAO/WHO powder MPL 400 ppb as screening context (not an EU 2023/915 ML; no daily MADL locked)
- Ranking weights (editorial, disclosed — not half-lives):Lead ×0.35Inorganic Arsenic ×0.30Cadmium ×0.20Aluminum ×0.15Missing key metal contributes HQ proxy 0.4 (uncertainty), not 0. score ≈ 100 / (1 + weighted mean HQ). Untested (empty labs) score 0 and sort last.
- Still kept from honesty PRs: EU 2023/915 Pb/Cd powder max lines on MetalBar; arsenic powder flag caps score at 49; no invented µg/kg labs.
EU maxima vs intake listing
Reg (EU) 2023/915 sets powder maximum levels for lead (20 µg/kg) and cadmium in cow’s-milk infant formula (10 µg/kg). There is no specific Union ML for aluminum in infant formula in that regulation. The United States has no FDA numerical ML for lead, cadmium, or aluminum in infant formula powder — we label that honestly rather than invent a US ppb line.
HiPP Dutch Organic Stage 1 (CR March 2025) vs EU 2023/915
| Metal | CR / app (ppb) | EU ML (ppb) | Under ML? |
|---|---|---|---|
| Lead | 2.1 | 20 | Yes |
| Cadmium | 3.4 | 10 | Yes |
| Aluminum | 160 | No EU IF ML | N/A |
HiPP Dutch Stage 1 CR traces sit under EU Pb/Cd maxima and still show estimated ~1-year intake + % of MADL on Detail — under the ML is not “zero metals,” and parents should still see the year-window listing.

Honest answers
Should I stop using a formula that shows detectable heavy metals?
Not on your own — talk to your pediatrician first. Heavy metals are present at trace levels in nearly all foods because they exist in soil and water. Suddenly switching or diluting formula can be more harmful than the trace exposure itself. Use this data to choose lower-testing options going forward, not to panic about the past.
Why do European formulas appear here?
EU regulations on infant formula composition differ from US rules in ways many parents care about (for example, stricter pesticide rules and lactose-first carbohydrate requirements). Several European and Australian brands now sell US-compliant versions through official channels, and independent testing covered them alongside American brands.
Is a low screening score the same as "unsafe"?
No. The draft screening score estimates formula-window intake under a disclosed feeding scenario and compares it to named protective anchors (MADL/RfD where cited). Anchors are not diagnoses, not “will cause harm,” and not EU legal maxima. Regulators determine legal sale. Use the year-window listing to choose — and talk to your pediatrician.
Where does the data come from?
Heavy-metal levels come from Consumer Reports’ March 2025 independent laboratory testing of 41 powdered infant formulas. Good Formula is not Consumer Reports and is not affiliated with Consumer Reports. Recall history is curated from FDA public announcements. Prices are approximate US retail and vary by store. Not medical advice.
Why doesn’t every formula show every metal?
Where a metal is not listed, it was not reported in that round — we show it as not tested / unknown. Missing is not a cleanliness bonus and is not a medical all-clear. Prefer formulas with fuller measured rows when comparing.
What about lifetime exposure and body burden?
This draft does not model body burden, clearance, or half-life. Sol 5.6 rejected LeaveDuration×risk “lifetime/retained” math. Parents see estimated intake over a ~1-year formula window at a disclosed oz/day, plus distance from named protective anchors.
