Who Needs Optimal Prenatal

Have you experienced preterm birth or other pregnancy complications? Are you concerned about nutritional deficiencies? If so, you may be wondering how to best support a healthy pregnancy.*

Pregnancy should be a beautiful and transformative experience. Worrying about your health and baby’s only puts more stress on this delicate time.

Are you seeking a potent and comprehensive prenatal? One that contains key nutrients needed for a healthy pregnancy? Look no further.*

Optimal Prenatal is a powerful, nutrient-dense prenatal multivitamin formulated by epigenetics expert, Dr. Ben Lynch.*

Optimal Prenatal resulted from years of research into epigenetics, fertility, and pregnancy, including the MTHFR gene variation. It is designed for women who need more intense nutritional support and want to support a healthy pregnancy. This includes those experiencing nutritional deficiencies, pregnancy complications, or difficulty conceiving.*

Doctors recommend folate and B12 during pregnancy. These essential nutrients are known to reduce the risk of neural tube defects (e.g., spina bifida), as well as other birth defects and pregnancy complications.*

Optimal Prenatal contains B12 and folate in their bioavailable, methylated forms. Your body needs these active forms for proper methylation, which is essential for healthy fetal development.*

What you’ll never find in any of Seeking Health’s dietary supplements is folic acid. This artificial version of folate can cause many side effects and may even contribute to folate deficiency!*

Optimal Prenatal also contains vitamin D to support baby’s brain development and over 30 important nutrients for pregnancy health. Unlike some other over-the-counter formulas, Optimal Prenatal contains choline, which is required in higher amounts during pregnancy due to accelerated cell division.*

It is recommended to start taking prenatal vitamins for several months before trying to conceive. Optimal Prenatal can be taken before and throughout your entire pregnancy to optimize preconception health and to support a healthy pregnancy.*

Continue Optimal Prenatal after birth to support breastfeeding and replenish nutrients lost from pregnancy. In fact, anyone seeking a nutrient-dense multivitamin can take Optimal Prenatal, including men looking to optimize their preconception health!*

Optimal Prenatal has helped thousands of mothers to support healthy fertility, pregnancy, breastfeeding, and postpartum recovery. Women love that they’re easy on the stomach, which is particularly important if you experience morning sickness!*

Hundreds of 5-star reviews point to Seeking Health’s Optimal Prenatal as one of the best prenatal vitamins on the market.*

Seeking Health prenatals are recommended by doctors worldwide. Now, you can feel confident knowing you have everything you need to optimize your prenatal health and support baby’s development!*

Why Optimal Prenatal Works

It’s well known that a healthy diet coupled with a high-quality prenatal vitamin can go a long way to promote a successful pregnancy.*

Optimal Prenatal is formulated by epigenetics expert, Dr. Ben Lynch ND, using only superior and bioavailable forms of key nutrients. Its unique formulation is based on the enzymatic pathways involved in pregnancy and genetic development. Enzymes in these pathways require specific nutrients as cofactors. Arguably, the most critical of these nutrients are the active and bioavailable forms of folate and B12.*

Your MTHFR gene converts and produces folate (5-MTHF) from whole foods. However, MTHFR gene variations or lifestyle stress can slow down this gene, causing folate deficiency. It is estimated that over 50% of the population has a mutation in their MTHFR gene.*

By supplementing with the natural form of folate as 5-Methyltetrahydrofolate (5-MTHF), you bypass the MTHFR gene. This supports methylation by allowing folate to flow into the methylation pathway via the MTR enzyme.*

Ironically, the artificial version of folate that is often prescribed to pregnant women, called folic acid, can further slow the MTHFR gene. This can even lead to folate deficiency! Folic acid is never included inany of Seeking Health’s dietary supplements. Instead, we use natural and bioavailable forms, including 5-MTHF (methylated) and methyl-free folinic acid.*

Optimal Prenatal

The active or methylated form of vitamin B12, methylcobalamin, is essential for proper folate utilization, methylation, DNA expression, and much more. Without sufficient levels of bioavailable folate and B12, the fetus cannot effectively develop and express its genetics.*

Optimal Prenatal contains methylfolate, methylcobalamin, and over 30 bioavailable nutrients to support optimal genetic development.*

Pregnancy is hard, but choosing your prenatal doesn’t need to be. If you’re looking for the best prenatal on the market, Optimal Prenatal is for you.

* This product is not intended to diagnose, treat, cure, or prevent any disease.

Who is Optimal Prenatal intended for?

Optimal Prenatal is intended for women who are trying to conceive, pregnant, or breastfeeding, and who prefer a capsule delivery method. It is great for those needing a potent prenatal vitamin to support higher risk pregnancies, nutritional deficiencies, or are looking for a comprehensive, nutrient-dense daily multivitamin.*

This product may also be taken by men to promote healthy fertility and overall wellness when trying to conceive.*

Does Optimal Prenatal contain gluten or grains?

Optimal Prenatal is gluten-free.

Optimal Prenatal does not contain grains. However, this formula contains ascorbyl palmitate and vitamin C from corn. Due to the processes used to manufacture the finished ingredients, the final product is free from corn proteins.

Is Optimal Prenatal free of GMOs?

Testing confirms that Optimal Prenatal is free from GMO markers

Why is Optimal Prenatal unsuitable for vegans?

Optimal Prenatal is suitable for vegetarians. The vitamin D3 is derived from lanolin from sheep’s wool, making this product unsuitable for vegans.

I see that there is a 2016 study showing high levels of B12 associated with autism. How then do you have so much B12 in your Optimal Prenatal?

Optimal Prenatal is designed for women – and men – who are quite deficient in many nutrients, including B12. Many individuals are quite deficient due to their poor diet, genetic mutations, taking inferior supplements that are not well absorbed and utilized, and exposure to stress and toxins.

The study that references a link between B12 and Autism rates in 2016 is poorly conducted according to Dr. Lynch, including not listing the types of folate and B12 taken.

The B12 study didn’t look at the reasons why the mothers had high folate or high b12 – it just made an association between who supplemented more – and they also didn’t define what they supplemented with – or what forms of nutrients. According to Dr. Lynch, high levels of folic acid are really problematic – that’s no doubt.*

High folate and high B12 levels in blood are signs that it is not getting into the tissues.

This is because of Methyl Trapping. High levels of folic acid can decrease the levels of methylfolate and this can cause an indirect elevation of vitamin B12.

“In addition, a significant interaction was observed between plasma folate and B12 (p<0.001) suggesting possible perturbation in one-carbon metabolism, which intimately involves both micronutrients.”

Optimal Prenatal helps reduce incidence of methyl trapping by using active folates and active forms of B12.

Inactive forms of folate and B12 are problematic. We use active forms. If the gene MTR is slowed by yeast overgrowth, nitrous oxide, various medications, inflammation, low glutathione, heavy metals, then this can increase blood levels of folate and B12.*

There is no mention of which types of B12 and folates were used in their study – and there was no control over it – It was just a survey of who supplemented with a prenatal and how often.*

Dr. Lynch began his epigenetic research with the MTHFR gene, and its role in producing an active form of folate (5- MTHF) for DNA methylation. He found that without adequate levels of B12, methylation cannot occur. In addition to this, MTR mutations need vitamin B12 to convert homocysteine to methionine.*

More specifically, the National Institute of Health states that “The MTR gene provides instructions for making an enzyme called methionine synthase. This enzyme plays a role in processing amino acids, the building blocks of proteins. Specifically, methionine synthase carries out a chemical reaction that converts the amino acid homocysteine to another amino acid called methionine. The body uses methionine to make proteins and other important compounds. To function properly, methionine synthase requires methylcobalamin (a form of vitamin B12) and another enzyme called methionine synthase reductase, which is produced from the MTRR gene.”*


Dr. Lynch sees that most people are very deficient in B12 causing their folate to be unusable for methylation.

That being said, the Optimal Prenatal 8 capsule dose is the therapeutic dose for optimal nutrition. Not everyone needs this much nutrition. In fact Dr. Lynch believes that women should start out with 1-2 capsules, and only work their way up if needed. Talk to your qualified healthcare professional to determine if the dose is right for you, based on how you are feeling, and your symptoms.*

Optimal Prenatal is designed for women – and men – who are quite deficient in many nutrients, including B12. Many individuals are quite deficient due to their poor diet, genetic mutations, taking inferior supplements that are not well absorbed and utilized, and exposure to stress and toxins. *

Speak with your healthcare professional about consuming a smaller dose, as recommended by Dr. Lynch when starting out with your prenatal regimen – or any supplement regimen! Dr. Lynch recommends taking 1-2 capsules, and increasing only if needed. If you decide to consume the full dose of 8 capsules, it is best taken throughout the day to get a consistent influx of nutrients into your body; 3 in the morning with breakfast, 2 with lunch and 3 in the mid-afternoon with a mid-afternoon snack. Do not consume within 5 hours of bedtime due to the B vitamins that may interfere with sleep.

Why does Optimal Prenatal contain such a high amount of Vitamin A in the retinol form?

The body naturally converts the plant-derived beta carotene into the active retinol form of vitamin A via the BC01 enzyme. However, a  significant amount of the population has a polymorphism in the BCO1 gene which greatly reduces the ability to convert beta carotene to retinol vitamin A. Thus, a significant amount of the population may be vitamin A deficient if only ingesting beta carotene.

Optimal Prenatal contains approximately 750 mcg retinyl palmitate (retinol) and approximately 750 mcg beta-carotene. The beta carotene does not contribute towards the upper limit of vitamin A,  rather, it is considered a “provitamin” because it can be converted into vitamin A within the body. High amounts of retinol have been reported as potential factors in pregnancy issues or birth defects, however not beta carotene. Therefore this product does not exceed the established safe daily doses of vitamin A.

The tolerable upper limits for retinol vitamin A intake, according to the Food and Nutrition Board, are as follows:

Tolerable Upper Intake Levels (ULs) for Preformed Vitamin A
Age Male Female Pregnancy Lactation
0–12 months 600 mcg RAE(2,000 IU) 600 mcg RAE(2,000 IU)
1–3 years 600 mcg RAE(2,000 IU) 600 mcg RAE(2,000 IU)
4–8 years 900 mcg RAE(3,000 IU) 900 mcg RAE(3,000 IU)
9–13 years 1,700 mcg RAE(5,667 IU) 1,700 mcg RAE(5,667 IU)
14–18 years 2,800 mcg RAE(9,333 IU) 2,800 mcg RAE(9,333 IU) 2,800 mcg RAE(9,333 IU) 2,800 mcg RAE(9,333 IU)
19+ years 3,000 mcg RAE(10,000 IU) 3,000 mcg RAE(10,000 IU) 3,000 mcg RAE(10,000 IU) 3,000 mcg RAE(10,000 IU)

Vitamin A is an essential nutrient, especially during pregnancy and nursing. As with all supplements, we recommend that you consult with your doctor to determine whether this product will be appropriate for your individual needs. You should also take into account preformed vitamin A sources in your other supplements and in your diet when determining whether the dose of this product will work for you. You can also choose to take less than a full dose if you would rather take less vitamin A.
