HelloPharmacist Scorecard of Prenatal DHA Strawberry by Nordic Naturals
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Partial disclosure
Prenatal DHA Strawberry has 4 active ingredients: two omega-3 fatty acids (eicosapentaenoic acid and docosahexaenoic acid), vitamin D3, and a blend labeled "Total Omega-3s." The omega-3s are the main components—they're the fats your baby's brain and eyes develop with. Vitamin D supports bone health and calcium absorption for both you and your growing baby.
The softgel also contains inactive ingredients like fish oil, gelatin, glycerin, and vitamin E to protect the oil from breaking down.
Does it work?
Not established
Vitamin D is proven effective for preventing and treating rickets, osteomalacia (soft bones), familial hypophosphatemia, renal bone disease, and hypoparathyroidism. The evidence base for the omega-3 fatty acids in prenatal nutrition isn't covered in the data we hold, so we can't speak to their documented effectiveness from our records.
How safe is it?
Well-documented data
Vitamin D is generally well tolerated at recommended doses—the kind used in prenatal vitamins is designed to be safe during pregnancy. But very high doses over time can build up and cause toxicity, with symptoms like high blood calcium (hypercalcemia), eye inflammation, or too much bone loss.
The safety notes advise using vitamin D during pregnancy only under your doctor's guidance. Serious side effects are rare at normal doses, but excessive supplementation can cause trouble.
We have no pregnancy or lactation safety data on file for the omega-3 ingredients in this product.
Meds to double-check
Moderate interaction found
Before you take this, double-check if you're on thiazide diuretics (water pills), verapamil, diltiazem, or digoxin for your heart, atorvastatin for cholesterol, or calcipotriene for psoriasis—these are Moderate interactions with the vitamin D. If you have kidney disease or take aluminum-containing products, mention that to your pharmacist too.
For the omega-3 ingredients, we don't hold interaction data.
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 supplement is a common choice for omega-3 and vitamin D support in pregnancy. If you're on blood pressure pills, heart rhythm medications, cholesterol drugs, or anything for kidney disease, check with your pharmacist before starting—the vitamin D could matter.
Otherwise, at recommended prenatal doses, vitamin D is generally considered safe under your doctor's care.

Prenatal DHA Strawberry by Nordic Naturals Drug Interactions
HelloPharmacist Interaction Report
Prenatal DHA Strawberry by Nordic Naturals contains vitamin D3, which does interact with several medications.
The most serious concern involves thiazide diuretics (water pills for blood pressure)—vitamin D can theoretically increase calcium levels in your blood when combined with these drugs, which is especially risky at high doses. This same high-dose effect also applies to heart rhythm medications like verapamil, diltiazem, and digoxin, where elevated calcium can reduce how well they work or trigger dangerous arrhythmias.
Read the full breakdown — every affected drug type, severity by severity
Vitamin D may also reduce how your body absorbs atorvastatin (a cholesterol drug), though one small study showed this didn't always change cholesterol numbers significantly. High-dose vitamin D can increase aluminum absorption in people with kidney failure, and it shouldn't be combined with calcipotriene (a vitamin D-based skin cream for psoriasis).
There's also a theoretical concern that vitamin D might affect how your liver processes certain medications (CYP3A4 substrates), though the evidence is limited.
We could not check two of the active ingredients—eicosapentaenoic acid and docosahexaenoic acid (the omega-3 fatty acids)—because interaction data isn't available for them. We also hold no data on "Other Omega-3s" as listed.
Altogether, these interactions span 705 individual medications. Please use the search tool on this page to check your exact prescriptions before you start.

For each ingredient in Prenatal DHA Strawberry with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Vitamin D3
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.
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.
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.
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.
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.
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.
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.
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.
