Best Prenatal with Folate: A Pharmacist’s Guide to Folate and Iron

YoungLong banner: A Supplement Brand Made By Pharmacists, with two researchers examining a test tube in a lab


Key Takeaways


  1. The form of folate matters. More than half of Americans carry an MTHFR gene variant that can make converting folic acid into its active form less efficient, while active folate (5-MTHF) does not need this conversion step.

  2. Check what your iron is made from. Inorganic iron can irritate the stomach, and heme iron is less tightly regulated by the body, so plant-based ferritin iron from curry leaf offers a well-absorbed, plant-sourced alternative.

  3. YoungLong Vegetable Iron & Active Folate combines both in one formula. Each serving provides 24 mg of curry-leaf ferritin iron, 600 mcg DFE of Quatrefolic® active folate, vitamins B6 and B12, and vitamin C from amla in a vegan-certified formula.


 

Hello, I am a pharmacist at YoungLong.

To be honest, early in my wife’s pregnancy, I made a big mistake with her.

It was a careless remark I made while she was anxious about her upcoming prenatal screening.


“Folic acid? Just take the one the clinic gives you, or any kind at all. They are all the same.”

A few days later, however, my wife showed me a post from an online community, holding back tears, and it came as a real shock to me.


“They say many expectant mothers cannot metabolize folic acid... If you take just any kind, it does not reach the baby. What should I do?”

Only then did I, as a pharmacist, hurry to look through the research, and I discovered a shocking fact.

A significant number of women have a genetic variant that makes it harder for their bodies to convert folic acid into its active form.

The thought that the “any kind” I had casually recommended might not be reaching my baby, and might instead be building up in my wife’s body as unmetabolized folic acid, frightened me deeply.

To make matters worse, my wife, who had started taking the iron supplement from the clinic, was suffering from severe constipation and vomiting.

“Honey, my stomach feels so unsettled. But I am afraid something will go wrong with the baby if I do not take it... I should keep taking it anyway, is that right?”

Watching my wife force down the pills for the baby, even while she was retching in the bathroom, I made a decision.

“As a pharmacist, I will find the safest and most reliable supplement in the world for my wife and our baby.”

From that day on, after closing the pharmacy, I looked through every research paper and ingredient supplier around the world until dawn.

Let me start with the conclusion.

Many of the products on the market labeled “for pregnancy” are ones I would not give my wife.

Today, with a pharmacist’s conscience and a father’s sense of urgency, we will walk you through “A Foolproof Guide to Choosing Folate and Iron During Pregnancy” in detail.

Please do not be misled by advertising claims, and please read this article to the end.



1. Folate in a Prenatal: The Gene Variant Most Americans Carry

Table of folic acid functions: cell and blood formation, normal fetal neural tube development, and normal homocysteine levels


Do you know why women take folic acid from the moment they begin preparing for pregnancy?

It is to support the normal development of the baby’s neural tube and to help with normal cell division.

I was searching for a folic acid product for my wife, but every time I looked at a Supplement Facts label, I found myself sighing.



Supplement Facts label showing 1,334 mcg DFE folate from 800 mcg folic acid per capsule


This is because the back of most products simply said “Folic Acid.”

Why did this make me, as a pharmacist, sigh?

Because it would mean leaving it to chance how efficiently my wife’s body could use the folate intended for our baby.



Folic Acid’s “Hidden Hurdle”

Best prenatal with folate guide: folic acid passes through DHF and THF, where a gene variant and UMFA can block conversion to 5-MTHF

When it comes to folate vs folic acid, the synthetic form we commonly take (folic acid) is not active in the body on its own.

It must go through several complex metabolic steps and be converted into its “active form” before the body can use it.

The problem is that more than half of people in the U.S. carry a variant in the gene for MTHFR, a key enzyme in this conversion, and the variant is more common among Hispanic Americans than among White or Black Americans.[1]


* Based on data from the U.S. Centers for Disease Control and Prevention (CDC)


Let me put it simply.

Even if 10 pregnant women diligently take regular folic acid, more than half of them are likely to carry this gene variant, which can make the conversion less efficient.

In addition, taking more folic acid than the body can convert at one time can leave some of it remaining in the blood as “unmetabolized folic acid (UMFA).”

Researchers are still studying whether unmetabolized folic acid that remains in the blood may have effects on the body.


So do I need a genetic test before taking it?

No, there is no need.

You can simply choose a folate that “does not need this conversion process” in the first place.



2. A Pharmacist’s Answer: 4th-Gen Active Folate (5-MTHF)


Choosing the best prenatal with folate: table comparing four generations of folate, from natural folate and folic acid to Metafolin and Quatrefolic


That is why I made “fourth-generation active folate” a requirement for any supplement I would give my wife.

Listed on Supplement Facts labels as “5-MTHF” or “methyltetrahydrofolate,” this ingredient is the final form of folate, already prepared in a form the body can use directly.

A gene variant? It makes no difference.

Lower enzyme activity? It is not a problem.



Best prenatal with folate comparison: folic acid needs several conversion steps, while active folate goes straight to 5-MTHF


Because it needs no conversion, the body can use it directly, and it is supplied to the baby through the mother’s bloodstream.

In early pregnancy, when the baby’s brain and nervous system are forming, this was not a time when I was willing to leave anything to chance.

I wanted to choose the form that skips the conversion step entirely.

In particular, I went as far as confirming that the product used authentic Quatrefolic® from Gnosis, an Italian company recognized worldwide for its safety and technology.


Have You Checked “What” Your Iron Supplement Is Made Of?

Once I had resolved the folate question, it felt as though, as the saying goes, there was another mountain beyond the one I had just climbed.

This time, the problem was the iron supplement.

That night, I threw away the bottle of iron supplements my wife had been taking, opened the professional textbooks at the pharmacy along with the research database PubMed, and studied through the night.

Why did my wife’s stomach become so upset, and why could she not have a bowel movement, every time she took an iron supplement?

The reason was much simpler, and more shocking, than I had expected.




3. Is Your Iron Supplement Made from Ground-Up “Stone”?

Illustrations of common iron supplement side effects: constipation, heartburn, and metallic taste


Most of you are probably familiar with the three most common side effects that pregnant women experience from iron supplements.

① Constipation (dark stools)
② Stomach upset and digestive discomfort
③ A metallic taste and nausea

A major cause of all this discomfort is “unabsorbed iron.”





Illustration of red blood cells flowing through a blood vessel


Most of the inexpensive iron supplements we commonly receive from pharmacies or clinics use inorganic iron, such as ferrous sulfate or ferrous fumarate.

Put simply, this is iron that has been chemically extracted from minerals or metal.

Once this type of inorganic iron enters the body, it can irritate the stomach lining.

This is why it so often leads to heartburn and stomach upset.

In addition, because its absorption rate is low, much of it passes into the intestines, where the leftover iron may feed harmful gut bacteria, which can contribute to gas and hard stools.


Then Why Not Simply Take Highly Absorbable “Animal-Based Iron (Heme Iron)”?

At first, I thought the same thing.

Heme iron, which is extracted from pig blood or the blood of other livestock, has a high absorption rate.

However, an even more alarming pitfall was hidden here.



A Key Drawback of Heme Iron? It Has Weaker “Brakes”!

Our bodies are designed to reduce iron absorption once they already have enough iron.

However, heme iron from animal sources is less tightly controlled by this regulatory system, so it can continue to be absorbed even when the body already has enough.

Iron taken in beyond what the body needs can promote the formation of “free radicals,” which can damage cells.

In other words, it can cause a kind of “rust” inside the body.

Also, because it is made from pig blood, I could not be sure how thoroughly its quality was controlled against pathogens or other contaminants.

In fact, a number of studies have raised concerns that excessive heme iron intake may be associated with effects on cardiovascular and colon health.

I could not take such a risky gamble during my wife’s pregnancy.



4. A Pharmacist’s Iron Solution: Plant-Based Ferritin

If animal-based iron is not an option, and synthetic inorganic iron is not an option either, then what should one take?


Plant-based ferritin graphic: slowly replenishes stored iron, with higher absorption and less stomach upset


While going through countless research papers, one term caught my attention: “plant-based ferritin.”

Many of you may be hearing this term for the first time.

However, ferritin is the form our bodies already use to store iron safely.

I focused on ferritin for just two reasons: “safety” and “intelligent design.”


Illustration of a protein complex inside a glowing bubble moving through the intestine


First, It Is Wrapped in a Natural Protein “Armor.”

Regular iron dissolves right away in the stomach, but ferritin iron is enclosed in a protective layer called a “protein shell.”

This shell helps it resist breakdown by stomach acid, so it can pass through the stomach more gently.

This may help reduce heartburn and nausea.

The shell also helps minimize the metallic taste typical of iron.


Second, It “Opens the Door” Only When the Body Needs It.

This is the key point.

In the body, ferritin stores iron, releasing it when iron runs low and holding on to it when there is enough.

Like an “intelligent reservoir,” it helps keep the body’s iron levels in balance.

This is one reason I felt reassured choosing it for my wife, as it may help ease concerns about oxidative stress from taking in too much iron.



5. Then “Which” Ferritin Should You Choose?


I now knew that ferritin was a good option.

However, I also found products on the market that appeared to simply add a coating to synthetic ingredients in order to imitate ferritin.

For my wife, I decided to look for something “truly derived from nature.”

What I found was “curry leaf.”


Fresh green leaves, a natural source of food folate


Curry leaf, a familiar ingredient in Indian cooking, is a plant that has long been used in traditional Ayurvedic practice.

Remarkably, the iron extracted from curry leaves naturally takes the form of ferritin.

It is not iron alone; the minerals and cofactors naturally present in the plant are bound together with the iron, which may support its absorption (bioavailability) in the body.



Our Search Ended with Curry Leaf Ferritin

Iron that is plant-based (plant-based),
well absorbed (ferritin structure),
and naturally sourced (natural origin).

Of all the ingredients I searched through around the world, the only one that met all three of my criteria was “curry leaf–derived ferritin iron.”



Should Folate and Iron Be Taken Separately?

Many people believe that “iron and folate supplements should be taken separately because they compete for absorption.” This is only partly true.

It is often said that conventional inorganic iron and synthetic folic acid may interfere with each other’s absorption.

However, the “plant-based ferritin iron” and “active folate” I described earlier are absorbed through different pathways, and they were chosen as forms that help minimize interference with each other.

In fact, iron and folate are essential partners in “hematopoiesis” (the process of making blood).

Making red blood cells requires not only iron but also folate, vitamin B6, and vitamin B12 working together to produce healthy blood.


So, to ease the supplement burden on expectant mothers by reducing the number of pills they need to take, YoungLong searched for a way to combine all of these carefully chosen ingredients in a single formula.


How YoungLong Brought It All Together

YoungLong Vegetable Iron & Active Folate box, 60 capsules


Based on everything above, YoungLong set three non-negotiable criteria for this formula.

① Fourth-generation active folate (5-MTHF)
② Plant-based ferritin iron (curry leaf)
③ A clean label with no synthetic excipients


Verified on the Supplement Facts Label

Curry leaf extract powder
This is the core ingredient: plant-based ferritin iron. Each serving provides 24 mg of iron, about 89% of the 27 mg recommended daily for pregnancy.[3]

(6S)-5-Methyltetrahydrofolate, glucosamine salt (Quatrefolic®)
The name is long, but it simply means fourth-generation active folate. Because it is already in its active form, no conversion step is needed. Each serving provides 600 mcg DFE, matching the recommended daily amount for pregnancy.[3]

Dried yeast (vitamin B6 and B12)
These are iron’s partners. We included these B vitamins, which support normal red blood cell formation, from a natural source.

Indian gooseberry (amla) extract
This provides vitamin C, which helps the body absorb iron, so there is no need to drink a separate glass of orange juice.

Fructooligosaccharides (FOS) and probiotics
We added these with digestive comfort in mind.


As you can see, the label contains no synthetic additives. Instead, organic fruit and vegetable powders fill that space.


Vegetable Iron & Active Folate May Be a Good Fit If:

  • You are concerned that you may be among the more than half of Americans who carry an MTHFR gene variant

  • Conventional iron supplements have been hard on your stomach during pregnancy

  • You want ingredients sourced from nature for your baby


For about the price of a few cups of coffee a month, choosing Vegetable Iron & Active Folate can be a thoughtful investment in the months before your baby arrives.
