PRODUCT FAQ

TheraNatal Core is a daily preconception prenatal for any woman trying to conceive.* It is designed specifically to prepare your body for pregnancy with methylated folate, 50 mcg (2,000 IU) of vitamin D3, 100 mg of choline, 220 mcg of iodine, and other fertility focused ingredients.*

Q. Should I continue taking TheraNatal Core once I find out I'm pregnant?

Yes. TheraNatal Core supports your nutrient needs while you are trying to conceive and during early pregnancy (through your first trimester). Before beginning your second trimester, it is best to switch to a prenatal vitamin designed for pregnancy, like TheraNatal One or TheraNatal Complete.

Q. What is the difference between TheraNatal Core and TheraNatal OvaVite?

TheraNatal Core is a daily preconception tablet for any woman trying to conceive.*

TheraNatal OvaVite is comprised of the TheraNatal Core tablet PLUS two coenzyme Q10 (CoQ10) softgels. CoQ10 is a nutrient that supports mitochondrial energy production for healthy egg quality.* Egg quality declines with age, women in their mid-30s and beyond may want to consider TheraNatal OvaVite.

Q: Can I take TheraNatal Core if I'm allergic to shellfish?

Yes. There is no shellfish in TheraNatal Core. If you have reacted to radiocontrast material or antiseptics which contain iodine, you may still be able to safely take TheraNatal Core even though it contains iodine. These reactions are commonly confused with sensitivity to iodine or shellfish, though studies have shown that they are not related.

Q. Can I take other nutritional supplements along with TheraNatal Core?

Yes. Certain other supplements can be taken along with TheraNatal Core (like omega-3 fish oil or other single-nutrient fertility supplements such as DHEA, inositol, and others). However, do not take any type of multivitamin or other prenatal while taking TheraNatal Core.

Q. Does TheraNatal Core interact with any prescription medications?

As with any dietary supplement, it is recommended you discuss with your pharmacist and or health care team to clarify whether TheraNatal Core can be taken along with your medications.

Medications that are changed by the liver Cytochrome P450 3A4 (CYP34) substrates (lovastatin, clarithromycin, estrogens and others) - CYP34 are important enzymes in your body, mainly found in the liver to break down medications in the body. Vitamin D may increase how quickly the liver breaks down some medications. Taking TheraNatal Core, which contains 50 mcg (2,000 IU) vitamin D, along with some medications may decrease the effectiveness of some medications. Before taking TheraNatal Core, talk to your healthcare provider to determine if you are taking medications that are changed by the liver.

TheraNatal Core may also affect the absorption of certain prescription medications as follows:

Antibiotics: Calcium, magnesium, iron, zinc (in TheraNatal Core) can bind to antibiotics in the stomach and reduce their absorption and effectiveness. Depending on the antibiotic prescribed, you may need to separate taking any multivitamins from antibiotics by at least 2 to possibly 6 hours or discontinue taking a multivitamin while taking the antibiotic. Please discuss with your pharmacist and healthcare team to determine if you should stop taking your multivitamin for a short period of time.

  • • Penicillamine (Cuprimine, Depen) – Separate by 2 hours
  • • Cephalexin (Keflex) – Separate by a minimum of 3 hours
  • • Tetracycline antibiotics (doxycycline, minocycline, demeclocycline)- Separate by 4 hours
  • • Ciprofloxacin (Cipro), gemifloxacin (Factive), levofloxacin (Levaquin), Moxifloxacin (Avelox) – Separate by 6 hours


Atorvastatin (Lipitor) - This medication helps control cholesterol levels in the body. Taking it with TheraNatal Core, which contains 50 mcg (2,000 IU) of vitamin D, may decrease the amount of atorvastatin absorbed by the body. Separate by a minimum of 2 hours.

High Blood Pressure Medications (captopril, enalapril, losartan, valsartan, diltiazem, amlodipine, quinapril, hydrochlorothiazide, furosemide): Iron and magnesium (in TheraNatal Core) can affect the absorption of this specific antihypertensive medication. Separate by 2 hours.

Digoxin (Lanoxin) – This medication helps the heart beat more strongly. Taking magnesium(in TheraNatal Core) at the same time as this medication may decrease the absorption of this medication, therefore, decreasing the effectiveness. Separate by 2 hours.

Dilantin (phenytoin) – This medication is an anti-epileptic drug used to control seizures. Calcium and magnesium (in TheraNatal Core) can affect absorption of this antiepileptic medication. Separate by 2 hours.

Oral Bisphosphonates (i.e., alendronate (Fosamax), etidronate (Didronel), risedronate (Actonel), ibandronate (Boniva), tiludronate (Skelid)) – These medications alter bone formation and breakdown in the body, slowing down bone loss and helping to prevent bone fractures. Taking magnesium, calcium and or iron (in TheraNatal Core) along these medications can decrease how much bisphosphate the body absorbs. Separate by 2 hours.

Sotalol (Betapace) - This medication helps the heartbeat normally in people with certain heart rhythm disorders. Calcium and magnesium (in TheraNatal Core) can affect absorption of this antiarrhythmic medication. Separate by at least 2 hours.

Thiazide diuretics (aka: water pills) – These medications are used to treat high blood pressure, congestive heart failure as well as the accumulation of fluid and swelling (edema) in the body. These medications also increase the amount of calcium in the body. Vitamin D helps your body absorb calcium. Taking TheraNatal Core, which contains 50 mcg (2,000 IU) vitamin D, along with these medications may cause too much calcium in the body.

Thyroid hormone (levothyroxine, Synthroid) - This medication is used to treat an underactive thyroid gland. Iron, calcium, and magnesium (in TheraNatal Core) can reduce absorption of these thyroid hormone medications. Separate by at least 4 hours.

Warfarin (coumadin) - Studies show that low-dose vitamin K (100 mcg) is unlikely to affect INR and may actually help to stabilize INR levels. TheraNatal Core contains 90 mcg of vitamin K and should be safe to take.
