One A Day Prenatal Advanced is a two-part prenatal multivitamin designed for use before, during, and after pregnancy. Each daily serving combines a multivitamin softgel with a separate choline tablet. Together, they provide 800 mcg of folic acid, 27 mg of iron, 200 mg of DHA, and 110 mg of choline.
The formula covers several important pregnancy nutrients, but it has limitations. You must take two pills daily, the choline amount does not meet the full pregnancy intake target, and the softgel contains fish and soy. This review examines the verified ingredients, safety concerns, customer experiences, and practical value.
QUICK VERDICT
7.5/10 Editorial assessment
A practical prenatal formula with meaningful folic acid, iron, DHA, and some choline. Its main drawbacks are limited choline and calcium coverage, fish and soy allergens, and mixed reports about smell and tolerance.
Best for: Adults seeking a prenatal supplement that combines DHA, folic acid, iron, and added choline.
Skip if: You have a fish or soy allergy, require a vegetarian supplement, or cannot tolerate fish-oil softgels.
Bottom line: Worth considering if the ingredient amounts match your needs, but it does not replace a balanced diet or personalized prenatal care.
Editorial score based on product information and reported usability, not independent laboratory or clinical testing.

What Is One A Day Prenatal Advanced?
One A Day Prenatal Advanced is an over-the-counter prenatal multivitamin made by One A Day, a Bayer consumer health brand. It is intended to support nutritional needs during preconception, pregnancy, and the postpartum period.
Unlike a typical one-pill prenatal, this product separates its nutrients into two forms. The softgel supplies vitamins, minerals, and fish-derived omega-3 fatty acids. The second tablet provides additional choline.
This matters because choline is often missing or present in small amounts in prenatal supplements. However, adding choline does not automatically make the formula nutritionally complete for every person.

What’s in the Bottle?
The standard 120-count package contains 60 prenatal multivitamin softgels and 60 choline tablets. Because you take one of each daily, this package provides 60 daily servings.
The two-part design allows the brand to include a separate dose of choline. Its main practical disadvantage is that you must remember both pills rather than taking a single prenatal softgel.
One A Day Prenatal Advanced Pros and Cons
The main strength of this prenatal supplement is its combination of commonly recommended nutrients. Its biggest limitations concern nutrient amounts, ingredients, and individual tolerability.
Pros
- Includes 800 mcg folic acid, 27 mg iron, and 200 mg DHA.
- Adds 110 mg choline in a separate daily tablet.
- Combines key prenatal nutrients in a two-pill daily routine.
Cons
- Contains fish and soy and uses gelatin.
- Provides only 110 mg of the 450 mg pregnancy choline target.
- Some buyers report fishy odor, aftertaste, or leaking softgels.
The two-pill routine may be manageable if you already take supplements with breakfast or dinner. However, anyone with severe morning sickness or difficulty swallowing pills may prefer a different format.
One A Day Prenatal Advanced Ingredients and Benefits
The formula combines folic acid, iron, DHA, and choline with several other vitamins and minerals. Each nutrient supports different parts of pregnancy nutrition, but no single supplement can replace an adequate diet.
Folic Acid: 800 mcg
Folic acid is particularly important before conception and during early pregnancy. It helps the developing neural tube form properly and reduces the risk of certain birth defects affecting the brain and spine.
The softgel supplies 800 mcg of folic acid, listed as 1,330 mcg dietary folate equivalents (DFE). The DFE measure accounts for differences in how the body absorbs folate from various sources.
The Centers for Disease Control and Prevention recommends 400 mcg of folic acid daily for everyone capable of becoming pregnant. Your prenatal clinician can determine whether this product’s dose is appropriate for your individual situation.
Choline: 110 mg
Choline supports cell membranes, nervous system development, and several functions involved in brain development. Its inclusion is a useful feature because some prenatal multivitamins contain none.
However, the 110 mg provided by One A Day Prenatal Advanced is not the full recommended amount. The adequate intake during pregnancy is 450 mg daily.
That means you must obtain additional choline from food or other clinician-approved sources. Eggs, meat, fish, soybeans, and certain vegetables can contribute to your daily intake.
DHA: 200 mg
Docosahexaenoic acid (DHA) is an omega-3 fatty acid involved in brain and eye development. The product supplies 200 mg of DHA from fish oil, along with 35 mg of EPA.
Including DHA in the prenatal softgel may be convenient for someone who does not regularly eat lower-mercury fish. However, DHA supplements are not a substitute for all the other nutrients supplied by seafood and a balanced diet.
Iron: 27 mg
Iron helps the body produce hemoglobin, which carries oxygen in the blood. Iron needs increase during pregnancy as blood volume expands and the developing baby requires iron.
This formula supplies 27 mg, matching the recommended daily dietary allowance during pregnancy for adults. That is a meaningful amount, but additional iron is not appropriate for everyone.
Too much supplemental iron can cause problems. Your clinician may assess anemia risk and review blood-test results before recommending any extra iron.
Calcium, Iodine, Vitamin D, and Other Nutrients
The softgel also includes 150 mg calcium, 150 mcg iodine, 15 mcg vitamin D, 40 mg magnesium, vitamin B12, zinc, and other nutrients.
Calcium and vitamin D support bone health, while iodine is needed for thyroid function and fetal nervous system development. Vitamin B12 contributes to normal blood and nerve function.
According to the NIH Office of Dietary Supplements, the recommended calcium intake during pregnancy is 1,000 mg daily for adults ages 19 to 50. The iodine recommendation is 220 mcg daily.
Because this supplement contains less than those amounts, the rest must come from your diet or a personalized nutrition plan.
Choline, DHA, folic acid, and iron support different aspects of pregnancy nutrition. Their benefits depend on adequate total intake, not simply taking more supplements.
Best Uses for One A Day Prenatal Advanced
This supplement is marketed for several reproductive stages. The most useful approach is to consider what your diet already supplies and which nutrients may need attention.
Before Pregnancy
If you are planning to conceive, a prenatal supplement with folic acid may help you establish a consistent routine before pregnancy begins.
Folic acid is especially valuable during the earliest stage of pregnancy, often before someone knows they are pregnant. Discuss your supplement plan early if possible.
During Pregnancy
During pregnancy, One A Day Prenatal Advanced can contribute folic acid, iron, DHA, and several other vitamins and minerals to your overall nutrition.
It may appeal to people who want these nutrients in one packaged daily regimen. Still, the formula’s choline and calcium amounts make food choices important.
After Delivery and While Breastfeeding
The manufacturer also markets the product for use after pregnancy. Nutritional needs remain important during postpartum recovery and breastfeeding.
However, the right supplement depends on your diet, breastfeeding status, medical history, and other products you take. Your healthcare professional can help determine how long to continue.
What Owners Report About One A Day Prenatal Advanced
Customer feedback is mixed, especially regarding smell and swallowing comfort. Reviews offer useful clues about daily use but cannot establish clinical effectiveness.
What Some Buyers Like
Several buyers describe the product as easy to include in their routine. Positive reports mention the combination of prenatal nutrients and the addition of choline.
Some reviewers say they experienced little aftertaste or nausea. Others appreciate taking two pills once daily rather than managing a more complicated supplement schedule.
Common Complaints and Watch-Outs
A recurring complaint concerns a strong fishy odor or taste. Some customers describe unpleasant burps after taking the softgel.
Other reviews mention oily residue or softgels that appear to have leaked inside the bottle. Several buyers report having good experiences with earlier bottles but problems with later purchases.
These accounts appear in customer reviews for One A Day Prenatal Advanced at Target. They represent individual experiences and should not be treated as proof that every bottle has the same problem.
If you receive damaged or leaking softgels, avoid taking them and contact the retailer or manufacturer. Do not assume a damaged product is safe simply because it contains fish oil.
Safety and Allergen Facts
One A Day Prenatal Advanced is not appropriate for every dietary restriction or medical situation. Its ingredient label and iron content deserve careful attention before use.
Does It Contain Common Allergens?
Yes. Bayer’s published ingredient information identifies fish and soy as allergens. The fish oil includes sources such as anchovy, sardine, and tuna.
The multivitamin softgel also contains gelatin and beeswax. For this reason, the complete daily regimen should not be described as vegetarian or vegan.
Although the brand identifies certain ingredients it does not use, that does not mean the product is suitable for every allergy.
Read the exact package label before use, particularly if you have known food allergies or ingredient sensitivities.
Can It Cause Side Effects?
Possible issues with iron-containing prenatal supplements include nausea, constipation, and stomach discomfort. Fish-oil softgels may also cause an unpleasant taste or burps in some users.
Taking the supplement with food follows the manufacturer’s instructions and may improve tolerance for some people. If you continue feeling unwell, discuss other prenatal options with your clinician.
Important Iron Safety Warning
Safety warning: Accidental overdose of iron-containing products can be fatal to young children. Keep the bottle securely out of children’s reach. If accidental ingestion or overdose occurs, seek immediate medical or poison-control assistance. Do not exceed the recommended dose.
According to Bayer’s supplement facts and safety information, adults should take one softgel and one tablet daily with food and should not exceed the recommended intake.
If you are pregnant, breastfeeding, taking medication, or managing a medical condition, consult your healthcare professional before using the product.
Who Should Take One A Day Prenatal Advanced?
One A Day Prenatal Advanced may suit adults who are planning pregnancy, currently pregnant, or recovering after delivery. The best fit depends on dietary needs and professional guidance.
Who May Benefit Most?
- People planning pregnancy: A prenatal supplement containing folic acid can help establish early nutritional support.
- Pregnant adults: The formula contributes nutrients commonly needed during pregnancy, including iron and folic acid.
- People seeking added choline: The separate choline tablet adds 110 mg to daily intake.
- People who want DHA included: The softgel supplies 200 mg of DHA without requiring a separate fish-oil bottle.
- Postpartum adults: The product may help support ongoing nutritional intake when recommended by a clinician.
Who Should Consider Another Prenatal?
- Anyone with a known fish or soy allergy.
- Vegetarians and vegans avoiding fish oil or gelatin.
- People who cannot comfortably swallow the softgel or tablet.
- Anyone who experiences persistent nausea or a strong fish-oil aftertaste.
- People whose clinician recommends a different dose or nutrient combination.
A supplement should match your needs rather than simply offer the longest ingredient list.
How to Take One A Day Prenatal Advanced
The manufacturer directs adults to take one multivitamin softgel and one choline tablet daily with food. Taking both consistently is necessary to receive the labeled daily amounts.
- Check the bottle: Verify the package seal, expiration date, ingredient information, and dosage instructions.
- Choose a meal: Breakfast, lunch, or dinner can provide a convenient time to remember the supplement.
- Take one softgel: Swallow the prenatal multivitamin softgel according to the package directions.
- Take one tablet: Take the separate choline tablet as directed.
- Maintain the routine: Use a daily reminder and store the bottle securely away from children.
Should You Take Both Pills at the Same Time?
The manufacturer recommends one softgel and one tablet daily with food. The standard directions do not require a complicated dosing schedule.
If you have trouble tolerating the regimen, ask your pharmacist or prenatal care professional whether a different schedule or product is appropriate.
What if You Miss a Dose?
Do not double your next dose to compensate for a missed one. Resume your routine according to professional or label guidance.
If you repeatedly miss doses because of nausea or difficulty swallowing, discuss a more manageable prenatal option with your healthcare professional.
One A Day Prenatal Advanced vs. Alternatives
One A Day Prenatal Advanced is not the only prenatal multivitamin that includes DHA or choline. Different formulas may be more suitable depending on your priorities, allergies, and nutrient requirements.
| Prenatal Supplement | Choline | Iron | Key Difference |
|---|---|---|---|
| One A Day Prenatal Advanced | 110 mg | 27 mg | Includes 200 mg DHA; two daily pills |
| One A Day Prenatal Multi | None listed | Included | Single daily softgel with DHA |
| Nature Made Prenatal Multi + Choline | 265 mg | 27 mg | More choline; includes 200 mg DHA |
| Thorne Basic Prenatal | 110 mg | 45 mg | Three capsules daily; no DHA listed |
One A Day Prenatal Multi
The regular One A Day Prenatal Multi uses one softgel daily. It includes DHA, folic acid, and iron, but it does not include the additional choline tablet found in the Advanced version.
It may suit someone who prefers a simpler one-pill regimen and obtains sufficient choline from food. However, reducing the pill count does not eliminate the need to check ingredient suitability.
Nature Made Prenatal Multi + Choline
Nature Made offers a prenatal package with a multivitamin softgel and a separate choline capsule. Its published formula provides 265 mg of choline, 27 mg iron, and 200 mg DHA per daily serving.
That makes it a useful comparison for buyers who specifically want more choline in their prenatal supplement. It still requires two pills daily, and total choline intake from food remains relevant.
These figures come from the official Nature Made formula.
Thorne Basic Prenatal
Thorne Basic Prenatal provides 110 mg choline and 45 mg iron per labeled three-capsule serving. It uses methylfolate and does not list DHA as part of its multivitamin formula.
Its higher iron amount and different folate form are important distinctions. It should not be assumed to be a better choice simply because some nutrient quantities are higher.
The manufacturer’s product information confirms these amounts. Ask your clinician whether the formula matches your needs, especially if you already receive additional iron.
Is One A Day Prenatal Advanced Worth the Price?
One A Day Prenatal Advanced may offer reasonable value if you want folic acid, iron, DHA, and added choline in one coordinated daily package. Its usefulness depends more on ingredient fit and tolerability than price alone.
The two-part formula can reduce the need to buy a separate choline supplement. On the other hand, its 110 mg choline contribution may be too low for someone relying heavily on supplements to meet daily choline needs.
A 120-count package provides 60 daily servings, not 120. Consider the cost per daily serving rather than the total number of pills shown on the bottle.
If you tolerate the softgel and your healthcare professional approves the formula, it may be a practical choice. If you experience persistent fishy aftertaste or need a different nutrient balance, another prenatal may offer better personal value.

Frequently Asked Questions
Does One A Day Prenatal Advanced Have a Smell or Aftertaste?
Yes, some buyers report a fishy smell, taste, or burps, while others notice little aftertaste. The DHA comes from fish oil, which may explain the odor. If softgels look damaged or have leaked, do not take them. Contact the seller or manufacturer about the bottle.
Can I Take It With Other Prenatal Supplements?
Do not combine it with another prenatal multivitamin unless your clinician approves. This product already supplies folic acid, iron, and other vitamins. Two formulas can push some nutrients above safe limits. Ask your clinician to review the labels of any additional iron, calcium, choline, or omega-3 product.
Is One A Day Prenatal Advanced Suitable for Vegetarians?
No, this is not a reliable vegetarian option. Its multivitamin softgel contains fish oil and gelatin, and the ingredients list also includes beeswax. The separate choline tablet does not make the full regimen vegetarian. If you avoid animal ingredients, ask about a suitable prenatal with an algae-based DHA source.
What Should I Do if I Miss a Daily Dose?
Do not double the next dose to make up for a missed day. Follow the package instructions and ask your pharmacist or prenatal clinician if you are unsure how to restart. If you miss doses often, keep the bottle where you normally eat, out of children’s reach, and use a daily reminder.
How Long Does One 120-Count Bottle Last?
A 120-count bottle is designed to last 60 days when it contains 60 softgels and 60 choline tablets. You take one of each per day, so 120 individual pills do not mean 120 daily servings. Check the specific product count before ordering, especially if the seller offers several pack sizes.
Does One A Day Prenatal Advanced Contain Fish or Soy?
Yes. The manufacturer’s ingredient information lists fish, including anchovy, sardine, and tuna, and soy. The softgel also contains gelatin. The absence of some other common allergens does not make the product allergy-free. If you have a fish or soy allergy, do not use it without advice from your allergy clinician.
Is 110 mg of Choline Enough During Pregnancy?
No, 110 mg is only part of the recommended choline intake during pregnancy. The NIH lists 450 mg per day as the adequate intake for pregnant adults. Foods such as eggs, meat, fish, and some beans can help provide the rest. Your clinician can assess whether your total diet is sufficient.
When Should I Start Taking a Prenatal Vitamin?
Ideally, discuss a prenatal supplement before trying to conceive. Folic acid is especially important before pregnancy and during its earliest weeks, when the neural tube develops. The CDC recommends 400 mcg of folic acid daily for anyone who could become pregnant. A clinician can confirm the right dose for your medical history.
Can One A Day Prenatal Advanced Upset Your Stomach?
Yes. Iron-containing prenatal vitamins can cause nausea, constipation, or stomach discomfort in some people, and fish oil may leave an aftertaste. The manufacturer’s directions say to take both pills with food. If symptoms continue or you vomit after taking a dose, ask your clinician for a different plan rather than doubling doses.
Can I Take One A Day Prenatal Advanced While Breastfeeding?
The brand markets Prenatal Advanced for use before, during, and after pregnancy, including breastfeeding. Nutrient needs still differ from person to person. Review the current label and your diet with your clinician, especially if you take other supplements, have anemia, or have an allergy to fish or soy.
Conclusion: Is One A Day Prenatal Advanced a Good Choice?
One A Day Prenatal Advanced combines several valuable prenatal nutrients in a practical two-pill regimen. Its 800 mcg folic acid, 27 mg iron, 200 mg DHA, and 110 mg choline make it a reasonable option to discuss with your prenatal care professional.
However, its choline and calcium amounts do not meet full daily pregnancy requirements. The presence of fish and soy, along with reported odor and tolerance issues, may also affect your decision.
Final verdict: Consider One A Day Prenatal Advanced if its formula fits your nutritional needs and dietary restrictions. Choose a different prenatal if you need more choline, an animal-free formula, or better personal tolerance.
