What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 3 of its 4 active ingredients.
  • “Total Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (830 mg) without saying how much of each component you get.

This prenatal formula contains 4 active ingredients. The two main omega-3 fatty acids are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) — both derived from fish oil and important for fetal brain and eye development.

You'll also get Vitamin D3, which supports calcium absorption and bone health during pregnancy, and a blend labeled Total Omega-3 Fatty Acids that includes other beneficial omega-3s. The softgels are made from gelatin, glycerin, and water, with purified deep-sea fish oil as the base and RRR-alpha tocopherol (a form of vitamin E) added as a preservative.

There are no artificial flavors or colors — just the unflavored formula itself.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Vitamin D's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Support fetal brain and visual development.
  • We looked for evidence on: Infant development, Child growth, Low birth weight, Fetal and premature infant mortality, Prematurity, Preterm labor — and 2 related terms.
  • The closest evidence on file: Vitamin D is rated "Insufficient Reliable Evidence To Rate" for Low birth weight (Natural Medicines).
  • Also on file: Vitamin D is rated "Insufficient Reliable Evidence To Rate" for Preterm labor, Fetal and premature infant mortality, Prematurity, Infant development, and more.

In our data, Vitamin D3 is rated effective for several bone and mineral disorders: familial hypophosphatemia, osteomalacia (soft bones), renal osteodystrophy (bone disease from kidney problems), rickets, and hypoparathyroidism. These ratings confirm its role in calcium and mineral metabolism.

We don't hold effectiveness ratings for the omega-3 fatty acids in this product — the evidence we have on file doesn't establish their benefit for pregnancy outcomes. That doesn't mean they're ineffective; it means we haven't indexed robust trial data for them in our system.

If you're curious about DHA and EPA for pregnancy specifically, ask your OB or midwife what the current research shows.

The evidence, ingredient by ingredient Vitamin D

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin D3 is generally well tolerated at recommended doses. Very high doses taken over time can cause toxicity with symptoms of high blood calcium (hypercalcemia), including calcification in the eyes, bone loss in adults, and slowed growth in children.

The product carries a caution that Vitamin D is often used during pregnancy at recommended amounts, but only under your doctor's guidance. The same caution applies if you're considering higher doses: check with your doctor first.

We don't hold safety data or adverse-effect information for the omega-3 ingredients in this product. Pregnancy and breastfeeding information isn't on file for those components either, so discuss them with your OB or pharmacist for personalized advice.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Vitamin D.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications.
  • For scale: 716 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with your pharmacist before taking this product if you're on verapamil (Calan), diltiazem (Cardizem), or digoxin (Lanoxin) for heart rhythm — Vitamin D3 at high doses can raise blood calcium and interfere with these drugs. Also mention thiazide diuretics (water pills), atorvastatin (Lipitor), or any medications broken down by your liver's CYP3A4 enzymes.

If you take aluminum-containing antacids and have kidney problems, that's another one to flag. The prenatal context means your doctor should oversee dosing anyway — use that visit to review your full medication list.

The bottom line

Scorecard at a glancePartially disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This prenatal DHA formula is designed for the omega-3s that support fetal development, with added Vitamin D3 for bone health. If you're on medications for heart rhythm, cholesterol, or blood pressure — or take thiazide diuretics — check your exact prescriptions with your pharmacist before starting, because Vitamin D3 can interact.

Stay within recommended prenatal doses of vitamin D and always take it under your doctor's supervision during pregnancy.

Vitamin D38 drug types · 715 drugs

Aluminum

Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption. This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically.

Likelihood Probable Evidence B
Atorvastatin (Lipitor)

Vitamin D might reduce absorption of atorvastatin.
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change. Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.

Likelihood Probable Evidence B
Calcipotriene (Dovonex)

Taking calcipotriene with vitamin D increases the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with vitamin D supplements might increase the risk of hypercalcemia.

Likelihood Probable Evidence D
Digoxin (Lanoxin)

Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.

Likelihood Possible Evidence D
Diltiazem (Cardizem, Others)

Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.

Likelihood Probable Evidence B
Thiazide Diuretics

Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently. This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily.

Likelihood Probable Evidence D
Verapamil (Calan, Others)

Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.

Likelihood Probable Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found. A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced. While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.

Prenatal DHA Unflavored Formula by Nordic Naturals: Common Questions

Does Prenatal DHA Unflavored Formula by Nordic Naturals interact with any medications?
Yes. Based on its ingredients, Prenatal DHA Unflavored Formula has a known interaction with 715 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Prenatal DHA Unflavored Formula contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe to take while pregnant?
The omega-3s and vitamin D3 in this formula are ingredients often used during pregnancy. However, vitamin D should only be taken at recommended amounts and under your doctor's guidance while pregnant. We don't have safety data on file for the omega-3 fatty acids themselves in pregnancy, so discuss the full product with your OB or midwife to make sure the doses and form are right for you.
Is this safe while breastfeeding?
Vitamin D3 at recommended doses is generally considered acceptable during breastfeeding, but check with your doctor before taking higher amounts. We don't hold breastfeeding safety data for the omega-3 ingredients, so talk with your doctor or pharmacist about whether the product is right for you.
What do the omega-3s in this formula do?
This product contains eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) — omega-3 fatty acids from fish oil that are important for fetal brain and eye development. The formula also includes other omega-3s, all derived from purified deep-sea fish oil.
Can I take this if I'm allergic to fish?
This product is made from fish oil, so it's not appropriate if you have a fish allergy. Talk to your doctor or pharmacist about omega-3 alternatives that would be safe for you.
What happens if I take too much vitamin D from this product?
Very high doses of vitamin D over time can cause toxicity, with symptoms like high blood calcium, bone loss in adults, and slowed growth in children. Stick to recommended prenatal doses and let your doctor know if you're taking other vitamin D supplements or fortified foods, so you don't accidentally exceed safe levels.
