4 at/over limit

Measured by an independent lab and compared against published safety limits.

Di(2-ethylhexyl) Phthalate (DEHP)1.41 ppmof 0.006 ppm

Over the limit — 235×US EPA drinking-water MCL, 40 CFR 141.61(c) — 0.006 mg/L. Applied to all foods as the TIGHTEST published DEHP number; the EU food-contact limit is looser (Reg. (EU) 10/2011 as amended by 2023/1442: SML 0.6 mg/kg, plus the 0.6 mg/kg DEHP-equivalent group limit with DBP/BBP/DIBP).

Mercury5 ppbof 2 ppb

Over the limit — 2.5×FDA bottled-water Standard of Quality, 21 CFR 165.110(b) — 0.002 mg/L

Di (2-ethylhexyl) Terephthalate78.2 ppmof 60 ppm

Over the limit — 1.3×EU food-contact plastics, Reg. (EU) 10/2011 — DEHT (FCM 798) SML 60 mg/kg, group restriction with DINCH. No tighter published limit exists (EFSA TDI 1 mg/kg bw/day).

Arsenic11 ppbof 10 ppb

Over the limit — 1.1×FDA bottled-water Standard of Quality, 21 CFR 165.110(b) — 0.010 mg/L (= EPA MCL)

Dibutyl Phthalate72.7 ppbof 120 ppb

61% of the limitEU food-contact plastics, Reg. (EU) 10/2011 as amended by 2023/1442 — DBP SML 0.12 mg/kg (cut from 0.3). Also inside the 0.6 mg/kg DEHP-equivalent group limit (DBP x5).

Diisodecyl Phthalate0.224 ppmof 1.8 ppm

12% of the limitEU food-contact plastics, Reg. (EU) 10/2011 as amended by 2023/1442 — DINP+DIDP group SML 1.8 mg/kg (sum). Applied to each alone.

Benzylbutyl PhthalateNDof 6 ppm

Not detectedEU food-contact plastics, Reg. (EU) 10/2011 as amended by 2023/1442 — BBP SML 6 mg/kg (cut from 30). Also inside the 0.6 mg/kg DEHP-equivalent group limit (BBP x0.1 = 6 mg/kg alone).

Bisphenol a (BPA)NDof 1 ppb

Not detectedEU Reg. (EU) 2024/3190 — BPA banned in food-contact materials from 20 Jan 2025 (old 0.05 mg/kg SML repealed); the residual exemptions require NO detectable migration at a 1 ug/kg detection limit. 1 ppb is therefore the tightest published number.

BpfNDof 10 ppb

Not detectedNot on the EU Union list of substances authorised in food-contact plastics (Reg. (EU) 10/2011 Annex I), and Reg. 2024/3190 restricts hazardous bisphenols; no migration is permitted. Set at 0.01 mg/kg, the detection limit 10/2011 uses for not-detectable (ND) restrictions.

BPS (Bisphenol s)NDof 50 ppb

Not detectedEU food-contact plastics, Reg. (EU) 10/2011 — BPS (4,4'-sulphonyldiphenol) SML 0.05 mg/kg; BfR applies the same 0.05 mg/kg.

CadmiumNDof 5 ppb

Not detectedFDA bottled-water Standard of Quality, 21 CFR 165.110(b) — 0.005 mg/L

Di-n-octyl PhthalateNDof 10 ppb

Not detectedDNOP is not on the EU Union list of substances authorised in food-contact plastics (Reg. (EU) 10/2011 Annex I), so no migration is permitted. Set at 0.01 mg/kg, the detection limit 10/2011 uses for not-detectable (ND) restrictions.

Dicyclohexyl PhthalateNDof 10 ppb

Not detectedDCHP is not on the EU Union list of substances authorised in food-contact plastics (Reg. (EU) 10/2011 Annex I), so no migration is permitted. Set at 0.01 mg/kg, the detection limit 10/2011 uses for not-detectable (ND) restrictions.

Diethylhexyl AdipateNDof 18 ppm

Not detectedEU food-contact plastics, Reg. (EU) 10/2011 — DEHA (FCM 207) SML 18 mg/kg.

DiethylphthalateNDof 10 ppb

Not detectedDEP is not on the EU Union list of substances authorised in food-contact plastics (Reg. (EU) 10/2011 Annex I), so no migration is permitted. Set at 0.01 mg/kg, the detection limit 10/2011 uses for not-detectable (ND) restrictions.

Dihexyl PhthalateNDof 10 ppb

Not detectedDNHP (di-n-hexyl phthalate, EU Repr. 1B) is not on the EU Union list of substances authorised in food-contact plastics (Reg. (EU) 10/2011 Annex I), so no migration is permitted. Set at 0.01 mg/kg, the detection limit 10/2011 uses for not-detectable (ND) restrictions.

Diisobutyl PhthalateNDof 150 ppb

Not detectedEU food-contact plastics, Reg. (EU) 2023/1442 group restriction — DBP x5 + DIBP x4 + BBP x0.1 + DEHP <= 0.6 mg/kg DEHP-equivalents, so DIBP alone may not exceed 0.15 mg/kg. DIBP is not itself an authorised substance.

Diisodecyl AdipateNDof 10 ppb

Not detectedDIDA (diisodecyl adipate) is not on the EU Union list of substances authorised in food-contact plastics (Reg. (EU) 10/2011 Annex I), so no migration is permitted. Set at 0.01 mg/kg, the detection limit 10/2011 uses for not-detectable (ND) restrictions.

Diisononyl 1,2-cyclohexanedicarboxylic AcidNDof 60 ppm

Not detectedEU food-contact plastics, Reg. (EU) 10/2011 — DINCH (FCM 775) group restriction with DEHT, 60 mg/kg. No tighter published limit exists (EFSA TDI 1 mg/kg bw/day).

Common questions

Is Thorne Prenatal DHA Dietary Supplement healthy?

Thorne Prenatal DHA Dietary Supplement scores 0/100 on Tallow — our avoid band. That number comes from what is on the label: the ingredients, how processed it is, and what it is packaged in. It is not a verdict on your diet — Tallow does not weigh calories, portion size or how often you eat it, so a high score means the ingredients are clean, not that the food is unlimited.

What is in Thorne Prenatal DHA Dietary Supplement?

Thorne Prenatal DHA Dietary Supplement lists 7 ingredients, starting with Dha, Epa, Omega-3 Fatty Acids, Gelatin and Glycerin. Ingredients are listed in descending order by weight, so the first few make up most of what you are eating.

Does Thorne Prenatal DHA Dietary Supplement contain seed oils?

No. Nothing in Thorne Prenatal DHA Dietary Supplement’s ingredient list matches a seed oil — canola, soybean, corn, cottonseed, grapeseed, sunflower, safflower, rice bran or peanut oil, or an unspecified "vegetable oil".

How processed is Thorne Prenatal DHA Dietary Supplement?

Thorne Prenatal DHA Dietary Supplement has no NOVA group. Tallow works NOVA out from the ingredient list, and it does not apply to supplements or non-food products; a food whose ingredients are not all classified yet stays unknown instead of being guessed. Either way the processing axis scores it neutrally.

How does Thorne Prenatal DHA Dietary Supplement compare to other omega & fish oil?

At 0/100 Thorne Prenatal DHA Dietary Supplement scores worse than most omega & fish oil we have scored. A higher-scoring option in omega & fish oil is WeightWorld Antarctic Krill Oil at 100/100.

Does Thorne Prenatal DHA Dietary Supplement contain heavy metals?

Yes. A lab detected arsenic at 11 ppb against a 10 ppb limit and mercury at 5 ppb against a 2 ppb limit in Thorne Prenatal DHA Dietary Supplement. It also tested for lead and cadmium and found none above its detection limit. Each reading is in the Contaminants section above.

Does Thorne Prenatal DHA Dietary Supplement contain phthalates?

Yes. A lab detected DEHP at 1.41 ppm against a 0.006 ppm limit, dibutyl phthalate at 72.7 ppb against a 120 ppb limit and diisodecyl phthalate at 0.224 ppm against a 1.8 ppm limit in Thorne Prenatal DHA Dietary Supplement. It tested for 8 other phthalates and found none above its detection limit. Each reading is in the Contaminants section above.
