Trying to conceive at 40+ has been difficult but this prenatal makes it a little bit easier. I'm currently 10 weeks and so grateful for finding this prenatal recommended in Real Food for Fertility by Lily Nichols. Such a good book and a great prenatal!" ~ Viti M.

I swear by this prenatal

I initially was taking another brand and then was recommended to the Seeking Health website by a holistic provider because the brand offers more pure vitamins/supplements. I swear this is the reason I’ve felt good my entire pregnancy. I have felt energized and so far 6.5 months in, no adverse pregnancy symptoms. Me and the baby are healthy and growing as we should!† - Katie

More Energy

First time using this prenatal and was with my 5th pregnancy. I felt better than I have during any of my previous pregnancies and truly think it helped take the edge off of first trimester nausea. Will never buy any other prenatal again! Especially knowing this is MTHFR friendly without the synthetic folic acid.† - MK S.

Why I Formulated Optimal Prenatal

My target was simple: formulate the best prenatal in the world. I recently re-evaluated every nutrient and form in this formula against current research and updated where the science justified it.

  • D3 is dosed per the research on pregnancy and lactation needs. 4,000 IU/day was the safest, most effective dose in a controlled pregnancy trial¹. Supports healthy bone development and immune system function.†
  • K2 (MK-7) works with D3 to direct calcium into bone, not soft tissue³, and has been shown to support healthy bone mineral density in mothers and the developing baby⁴.†
  • Boron supports healthy bone metabolism alongside calcium, magnesium, and D3⁵.†
  • Lutein and zeaxanthin (10:2 ratio) is based on research on infant visual development specifically, not adult eye-health ratios⁶.†
  • Choline and myo-inositol support neural tube and brain development not just during fetal development but for the baby's entire life⁷ ⁸ ⁹.†
  • Ginger, thiamine, and B6 support comfort through pregnancy-related nausea¹⁰.†
  • Chelated trace minerals absorb well and are gentle on a sensitive stomach.†
  • A full B-complex supports energy and mood at meaningful doses.†
  • CoQ10 and glutathione support healthy antioxidant status during pregnancy, when oxidative stress naturally rises¹¹ ¹² ¹³†
  • Both retinyl palmitate and beta-carotene forms of vitamin A are included because many women carry BCO1 variants that limit their ability to convert beta-carotene into active vitamin A on their own¹⁴. Vitamin A supports immune system function, eye development, and your baby's bone formation.†
  • Folate as both L-5-MTHF (methylfolate) and calcium folinate (folinic acid): methylfolate feeds the methylation cycle; folinic acid supports DNA base formation and new cell division, including healthy blood cell formation. Folate, B12, and B6 together support healthy homocysteine metabolism throughout pregnancy¹⁹ ²⁰.†
  • B12 as both methylcobalamin and adenosylcobalamin: methylcobalamin works with folate on methylation and nerve health; adenosylcobalamin is the mitochondrial form your cells need for energy production²¹.†

On purpose, not by accident:

  • No iron. It competes with calcium for absorption¹⁵ and is pro-inflammatory for many people. If you need it, add our Iron with Cofactors or our Iron Chewable.
  • No DHA. Most prenatals that include it don't include enough to matter¹⁶. Pair this with our Fish Oil for real EPA and DHA at doses that count, tested for purity and rancidity.†
  • Headaches, irritability, or trouble sleeping? Switch to Optimal Prenatal MF, which uses less stimulating forms of folate and B12²¹. As far as I know, we're the only company formulating a prenatal this way.†

Fertility Takes Two

If you're trying to conceive, remember that fertility takes two. Sperm quality matters as much as egg quality, and sperm take approximately 3 months to fully develop and mature.

I recommend your partner begin taking Optimal Man at least 3 months before you plan to conceive. This provides the methylation support, antioxidants, and nutrients needed to support healthy sperm development and DNA integrity during that critical window.†

Continue Through Breastfeeding

These recommendations don't stop at delivery. Breast milk is only as nutritious as the mother producing it. Every nutrient your baby receives through breast milk comes directly from your body's stores.

Continue taking Optimal Prenatal, Fish Oil, and Iron, throughout breastfeeding to provide nutrient-dense milk to your baby while protecting your own nutrient status. Many women become depleted during breastfeeding because they stop supplementing.†

Optimal Prenatal Is Right for You If:

You've experienced pregnancy loss, difficulty conceiving, or complications before, and you want to give this pregnancy every nutritional advantage you can.
Research has looked at antioxidant status and homocysteine levels in women who've faced these challenges¹ ⁵ ³ — Optimal Prenatal doesn't address those experiences directly, but it does provide active folate, B12, choline, and antioxidant support (glutathione, CoQ10) at levels many standard prenatals don't include, so your foundational nutrition isn't the thing left to chance this time.†

You're actively trying to conceive.
Preconception nutrient status supports healthy egg quality and early fetal development before a pregnancy test even turns positive. Choline supports fetal brain development from the earliest weeks¹, and myo-inositol supports neural tube development through a separate pathway from folic acid².†

You want the most comprehensive prenatal available.
With 31 researched ingredients—including nutrients most prenatals skip entirely—Optimal Prenatal provides intensive nutritional support for women who want to give themselves and their babies every possible advantage.†

You have genetic variations affecting nutrient metabolism.
Whether you have MTHFR, MTHFD1, DHFR, FOLR, PEMT, BCO1, or other polymorphisms, Optimal Prenatal provides bioavailable nutrient forms that work regardless of your genetic makeup—including methylfolate, folinic acid, methylcobalamin, choline, and preformed vitamin A.†

You want mood support during pregnancy.
The choline-inositol combination supports healthy neurotransmitter balance, helping maintain a positive mood throughout the hormonal changes of pregnancy.†

You're concerned about environmental exposures.
S-acetyl glutathione provides antioxidant support for a healthy response to the glutathione-depleting effects of common medications (Tylenol) and environmental exposures (chlorine, formaldehyde, arsenic).†

You experience morning sickness or digestive sensitivity.
Vitamin B6 (as P-5-P) and ginger root are included specifically to support digestive comfort during pregnancy.†

You're breastfeeding or postpartum.
Continue Optimal Prenatal after birth to replenish nutrients depleted during pregnancy and support healthy milk production.†

Optimal Prenatal Is NOT Right for You If:

You're sensitive to methylated nutrients.
If you experience extreme nervousness, irritability, sleep issues, or headaches when taking methylfolate, methylcobalamin or choline, choose Optimal Prenatal MF instead—it provides the same comprehensive support with non-methylated, bioavailable B vitamins.†

You want the essentials only.
If you're generally healthy with no prior pregnancy concerns and eat a very nutrient-dense diet, our Prenatal Essentials (2 capsules daily) may be sufficient for your needs.†

Optimizing Lives of Unborn Children™

Key Ingredients

Inside the Uncompromising Quality of Our Ingredients

Optimal Prenatal is a thoroughly researched, nutrient-dense prenatal multivitamin formulated by epigenetics expert, Dr. Ben Lynch.†

  • Active Folate (Quatrefolic®)
    Two natural folates are added by Dr. Lynch. There is no unnatural folic acid. L-methylfolate supports healthy methylation while folinic acid supports healthy blood cells, platelets, skin and neurotransmitters.†
  • Bioavailable B12 (MecobalActive®)
    'Adeno' and 'Methyl' are known as superior forms of vitamin B12 that your body can readily utilize, acting as coenzymes to power important enzymes. Bioactive B12 supports healthy energy production, detoxification and is required to utilize folate for methylation processes.†
  • Ginger Root & B6
    Support mother's comfort and digestion due to occasional nausea or morning sickness.†
  • Vitamin A
    This essential vitamin is critical for healthy fetal development. Most prenatals do not use retinyl palmitate, the active form of vitamin A. Dr. Lynch uses this form of vitamin A as it supports healthy eye, skin, bone, and immune system health in both the mother and developing baby.†
  • Choline(as Choline bitartrate)(VitaCholine®)
    Choline is an essential nutrient that supports the production of acetylcholine, a neurotransmitter involved in normal brain and nervous system function, including learning, memory, and muscle control. Choline also supports liver health by contributing to the formation of cell membranes and plays a role in normal lipid metabolism.†

    My fav prenatal

    I switched to these after having multiple miscarriages and discovering I have MTHFR gene mutation. Obviously I can’t give these complete credit because there are so many factors involved, but my next pregnancy was successful!

    Really disappointed in changing Seeking Health values and quality control

    ​I have taken Seeking Health prenatals faithfully for over 5 years, and up until recently, I would have recommended them to anyone. However, I am deeply disappointed by the direction the company’s values are taking.

    ​Recently, they started dropping little fragrance/scented tablets into the bottles that make the vitamins smell and taste like you are spraying perfume directly into your mouth— it is utterly disgusting. It has been horrible to take non pregnant as well as a nightmare for anyone dealing with pregnancy nausea. What’s worse, customers have been complaining about this orange-scented insert for at least 8 months, and the company is still shipping out bottles with it, stating they "don't know when new batches won't have it." Expecting loyal customers to just deal with it or to ship bottles back for a refund, all while letting this drag on for nearly a year, feels like corporate greed plain and simple.

    ​To make matters worse, it seems they have also lowered the amounts of some essential supplements, apparently trying to "serve more people" at the expense of formula potency.

    ​This isn't the first red flag, either. Previously, there was a California Proposition 65 warning on the Optimal Man vitamin. Thankfully, they seem to have resolved that issue. When you are paying a premium, top-tier price tag for supplements, there should be zero doubt about purity or potency. Men and women take these vitamins in the hopes of a healthy, optimal pregnancy—there is zero room for…

    Hi Abigail -

    Thank you for your feedback and your support over the years.

    Our values are not changing and, in fact, are getting stronger.

    The scented tablet in the Optimal Prenatal happened without my consent and we have adjusted the manufacturing process to not allow that again. I was pissed off as well. The new lot out now does not have that in there anymore. It's gone forever.

    We lowered some nutrients as I felt some should be lowered based on the feedback we have had over the years. We are actually increasing the folate back up to 600 mcg on the next round. I don't lower nutrients to save money - I do it because I truly believe they should be adjusted.

    Prop 65 does happen at times and we work hard to prevent it from happening. Supply chain throws curve balls on you. We have changed our processes here as well by creating a Prop 65 Estimator tool before we go to production. We also found a better supplier for the problematic ingredients which would usually test fine but then sometimes they would not.

    I do hope we continue to earn your business and trust.

    We aim to bat a 1000 but we do strike and miss at times.

    That said, the incoming lots should be free of Prop 65 and potencies should be in line. I have sourced superior herbs for Optimal Man which I'm excited about.

    In health,
    Dr. Lynch
