What makes a prenatal vitamin easier to absorb?

A prenatal vitamin is easier to absorb and tolerate when the nutrient forms in it are already close to the form your body uses, rather than forms that require extra conversion steps or tend to sit heavy on digestion. Methylated folate, chelated iron, and algae-sourced DHA are three of the biggest differences between a prenatal that gets finished and one that ends up back in the medicine cabinet after week two. The best prenatal is the one you can actually take every day without dreading it.

Always consult your healthcare provider before starting any new supplement, especially during pregnancy, breastfeeding, or while managing a medical condition.

Pink Stork's Total Prenatal, designed for preconception through breastfeeding, was built around this idea: a prenatal only works if it stays in your routine.

Why some prenatal vitamins are harder on your body than others

Not all nutrient forms are created equal. Folic acid, the synthetic form used in many prenatal vitamins, has to be converted by the body into an active form before it can be used.† Some women process that conversion step less efficiently than others.† Standard iron, like ferrous sulfate, is well absorbed but is also one of the most common causes of prenatal-vitamin dropout because of how it sits in the digestive system.†

Methylated folate versus folic acid

Methylated folate (5-MTHF) is already in the active form the body uses directly, which means it does not require the same conversion step folic acid does.† According to the National Institutes of Health Office of Dietary Supplements, methylfolate may be a better fit than folic acid for some individuals with certain gene variants, since their bodies can use this form more easily. Pink Stork's clean-label prenatal with 5-MTHF and iron bisglycinate uses methylated folate for this reason, supporting healthy fetal neural tube development in a form the body does not have to convert.†

Chelated iron versus standard iron

Iron bisglycinate, also called chelated iron, is bound to an amino acid before it reaches your gut, which changes how it is absorbed and tends to make it gentler on digestion than standard ferrous sulfate.† A randomized controlled trial of pregnant women found that ferrous bisglycinate supplementation was not associated with clinically significant gastrointestinal complaints, unlike some other iron forms tested in the same population. Total Prenatal is formulated with iron bisglycinate (Ferrochel) as part of its first-trimester sensitivity approach, supporting healthy iron status during pregnancy.†

What ScentCert technology addresses

Scent sensitivity is one of the most common and least discussed reasons women stop taking a prenatal in the first trimester. Total Prenatal includes ScentCert technology specifically to reduce scent-triggered nausea, so the supplement itself does not become the thing that makes you feel sick.†

What to do if your current prenatal is upsetting your stomach

• Check whether your iron is chelated (bisglycinate) or standard (sulfate, fumarate)
• Try taking your prenatal with food rather than on an empty stomach
• Pair it with a nausea-specific support if mornings are the hardest part of your day
• Talk to your provider before switching or stopping any prenatal, especially in the first trimester

For women whose mornings are dominated by nausea rather than pill-swallowing logistics, our organic ginger and vitamin B6 nausea lozenges are formulated to help ease occasional upset stomach and morning sickness alongside your prenatal routine.†

"So many people were just thrown on birth control. You have cramps? Birth control. Irregular periods? Birth control. Heavy periods? Birth control."

— Dr. Samantha Ess, ND, Naturopathic Doctor specializing in hormone health and fertility

Dr. Ess's broader point, that women's bodies deserve individualized answers rather than one-size-fits-all defaults, applies just as much to prenatal formulation as it does to hormone care. The same nutrient dose does not land the same way in every body, which is exactly why nutrient form matters.

"Through my own pregnancies, I learned that the right prenatal is not the one with the longest ingredient list. It is the one your body can actually keep down, morning after morning. That is why every ingredient we choose is backed by science and covered in prayer."

— Amy Suzanne Upchurch, Founder and CEO of Pink Stork

Frequently asked questions

Is methylated folate better than folic acid for everyone?

Not necessarily. Most people can process folic acid without issue, but methylated folate is already in the active form the body uses, which may be a more direct option for some individuals, according to the NIH Office of Dietary Supplements.

Why does iron upset my stomach so much?

Standard iron forms like ferrous sulfate are well absorbed but can be hard on digestion for some people. Chelated iron forms like iron bisglycinate tend to be gentler, according to Mayo Clinic and supporting clinical research.

Can I take my prenatal on an empty stomach?

Some people tolerate this fine, while others find it easier to take a prenatal with food. Talk to your provider about what works best for your body.

Should I switch prenatals if mine upsets my stomach?

Talk to your healthcare provider before switching, especially during the first trimester. Ask about the iron and folate forms in your current prenatal compared to alternatives.

Is Total Prenatal safe while breastfeeding?

Total Prenatal is formulated for preconception through breastfeeding. As always, consult your healthcare provider before starting any new supplement while breastfeeding.
