Fast Facts
Mamavation tested six popular omega-3 and DHA supplements through two EPA-certified laboratories.
All six contained ortho-phthalates, with total levels ranging from 117 to 6,193 ppb.
No detectable PFAS, glyphosate, or any of the 587 other tested pesticides appeared.
No supplement exceeded California heavy-metal warning thresholds, and one had none detectable.
What the Testing Found
Six popular omega-3 and DHA supplements were screened by EPA-certified laboratories for phthalates, heavy metals, PFAS, glyphosate and more than 500 other pesticides. The clearest finding: All six contained phthalates, with levels ranging from 117 to 6,193 parts per billion.
By contrast, the labs detected no PFAS, glyphosate or other tested pesticides in the products. Heavy-metal levels were below the study’s thresholds for a California Proposition 65 warning. One product had no detectable heavy metals.
What the Results Mean for Shoppers
These findings offer a useful snapshot, not a guarantee of safety. “Not detected” means a chemical was below the lab’s detection limit; it does not prove absolute absence. Also, the study summary does not identify which product had the lowest phthalate level, so it cannot support an overall “cleanest” ranking.
Still, the results show why independent testing can add information that ingredient labels do not provide. Phthalates may enter products during manufacturing, packaging or storage. Their detection does not, by itself, show that a supplement will cause harm. Exposure depends on factors such as dose and frequency.
A Helpful, Limited Snapshot
For everyday buyers, the practical message is to compare available test results, serving sizes and sourcing information rather than relying on price or marketing claims alone. Meanwhile, broader testing can encourage more transparent manufacturing and help companies find ways to reduce contamination.
The study tested only six products, and formulas or production practices can change. Its results do not predict what is in untested supplements or future batches. The study also disclosed that some links were affiliate links, which may help fund additional testing.
