Third-Party Heavy Metal Testing
Every batch of WeNatal for Her, WeNatal for Him, Omega DHA+, Egg Quality + and Magnesium undergoes rigorous third-party testing to ensure purity, potency, and safety.
- Lead (Pb)
- Arsenic (As)
- Cadmium (Cd)
- Mercury (Hg)
These tests are conducted by independent, accredited laboratories following cGMP (Current Good Manufacturing Practices) and FDA guidelines for dietary supplements.
Ingredient Sourcing & Quality Control
Sourced from trusted suppliers who meet stringent quality standards.
Purified & tested at multiple stages of production.
No fillers, artificial dyes, or unnecessary additives.
The United States Pharmacopeia (USP) limits for heavy metals in dietary supplements are:
| Heavy Metal | USP Daily Limit (µg/day) | WeNatal 3rd party Test Results (µg/day) |
|---|---|---|
| Arsenic (inorganic) | < 15 µg/day | 0.072 µg/serving |
| Cadmium | < 5 µg/day | 0.048 µg/serving |
| Lead | < 10 µg/day | 0.269 µg/serving |
| Methyl Mercury | < 2 µg/day | None detected |
Key Takeaway: WeNatal’s results are not only compliant but far below these strict USP limits.
WeNatal is well below the Strictest U.S. Standard: California Prop 65
California’s Proposition 65 has some of the most stringent heavy metal regulations in the world—much stricter than USP, WHO, and FDA standards.
| Heavy Metal | California Prop 65 Limit (µg/day) | WeNatal 3rd party Test Results (µg/day) |
|---|---|---|
| Arsenic (inorganic) | < 10 µg/day | 0.072 µg/serving |
| Cadmium | < 4.1 µg/day | 0.048 µg/serving |
| Lead | < 0.5 µg/day | 0.269 µg/serving |
| Methyl Mercury | < 0.3 µg/day | None detected |
Key Takeaway: We test every batch to ensure we remain well below Prop 65 standards, providing an extra layer of safety beyond national regulations.
Heavy Metal Exposure from Food vs. Supplements
An influencer who advocates for no lead has stated:
“In many cases, 'complete' prenatal vitamins are not actually required if it is possible to instead implement dietary changes that address any documented nutritional deficiencies you may have.”
While we always support a whole-food-based approach to nutrition, this statement ignores an important fact: Heavy metals are naturally occurring in food, and food is not routinely batch-tested for heavy metals before consumption.
This does not mean women should avoid food—just as it does not mean they should avoid a high-quality, third-party-tested prenatal like WeNatal.
The Reality of Heavy Metals in Food
Because heavy metals exist in soil and water, even organic foods absorb them naturally. Unlike supplements, food is not subject to routine heavy metal testing before consumption.
| Food Source | Lead (ppb) | Cadmium (ppb) | Arsenic (ppb) | Mercury (ppb) |
|---|---|---|---|---|
| Spinach (organic) | 30-50 | 30-50 | 30-50 | <1 |
| Brown Rice | 120-150 | 120-150 | 120-150 | <1 |
| Dark Chocolate | 100-200 | 100-200 | 100-200 | <1 |
| Fish (Tuna, Swordfish) | <10 | <10 | <10 | 500-1,000 |
| WeNatal Prenatal | <0.5 | <0.5 | <0.5 | None detected |
We agree that a nutrient-dense diet is always the foundation of good health. But prenatal supplements exist because many women struggle to consistently get all essential nutrients from food alone.
Just as it would be irresponsible to tell women to avoid eating nutrient dense food due to the presence of naturally occurring heavy metals, it’s also irresponsible to dismiss the benefits of a third-party-tested prenatal supplement—especially when testing standards designed for baby food are being misapplied to supplements.
Key Takeaway: If we applied the same standards to food as we do to supplements, many nutrient-rich foods—including spinach, rice, and seafood—would be flagged for heavy metal content. But avoiding these foods entirely would be impractical and unnecessary—just like avoiding a clean, third-party-tested prenatal. The benefits outweigh any potential risks.
The WeNatal Commitment:
Science Over Fear
Every batch of WeNatal supplements is third-party tested to ensure heavy metal levels remain below safe, regulated limits.
We comply with both USP and Prop 65 standards, exceeding national safety benchmarks.
We do NOT rely on fear-based marketing—we believe in science-backed formulations that truly support women’s health.
Bottom Line:
You Can Trust WeNatal
We created a prenatal because we couldn't find one that fit our high standards for safety and efficacy. Most prenatals on the market still do not meet expert-backed nutritional guidelines for pregnancy.
