Prenatal vitamin comparison: WeNatal vs. Ritual, Perelel, Bird & Be, Needed, and Thorne

Choosing a prenatal vitamin should be straightforward. In practice, it is anything but. The shelves are full of options, the marketing language all sounds the same, and the actual ingredient labels often tell a different story than the front of the bottle.

Consider this your side-by-side guide to how WeNatal for Her lines up against five prenatals you may have  seen: Ritual, Perelel, Bird & Be, Needed, and Thorne. Every one of these brands is trying to support the same goal, and several make genuinely thoughtful products that we are happy to credit along the way. This is a clear look at where these formulas actually differ, and why those differences matter across preconception, pregnancy, and postpartum, so you can choose with confidence rather than guesswork.

One idea shapes everything below, so it is worth naming up front. A well-built prenatal is not only about preventing nutrient deficiencies. It is also about helping you build and maintain healthy nutrient stores your body can draw on during the months that matter most. Those are two different jobs, and the dosage and form of each nutrient decide whether a prenatal can do the second one, not just the first.

WeNatal for Her delivers 24 key nutrients at clinically informed dosages in just 3 capsules per day. Compared with Ritual, Perelel, Bird & Be, Needed, and Thorne, WeNatal consistently provides higher amounts of the four nutrients most commonly underdosed in prenatal vitamins: choline (400 mg), folate as active 5-MTHF (1,350 mcg DFE), vitamin D3 (4,000 IU), and iron (18 mg in the bioavailable bisglycinate form). It also contains no fillers, binders, or synthetic colors, and uses bioavailable nutrient forms throughout. Individual needs vary, so it is always worth confirming your plan with your healthcare provider.

The four nutrients that matter most, and how WeNatal compares

Across every comparison in this article, four nutrients come up again and again because they are the ones most often included in name only. Here is where WeNatal for Her lands on each:

• Choline: 400 mg, compared with as little as 55 mg in some prenatals
• Folate: 1,350 mcg DFE as active, methylated 5-MTHF
• Vitamin D3: 4,000 IU, while most prenatals provide 1,000 to 2,000 IU
• Iron: 18 mg in the gentle bisglycinate chelate form

Keep these four in mind. They are the throughline of the entire comparison, and they are also the nutrients where the gap between "on the label" and "at a meaningful dose" tends to be widest.

Why nutrient form and dosage matter more than the label

Most prenatal vitamins list the right nutrients. The problems tend to show up in two quieter places: how much of each nutrient is included, and what form that nutrient takes. Both of those details decide whether your body can actually absorb and use what is in the capsule.

What "bioavailable" actually means

Bioavailability is simply how well your body can absorb and use a nutrient once you swallow it. Two prenatals can list the same nutrient and deliver very different results, because one uses a form the body recognizes easily and the other uses a cheaper form that requires extra conversion steps.

Folate is the clearest example. Folic acid is the synthetic form of vitamin B9. It works well for many people, but a large share of the population carries at least one variant in the MTHFR gene that affects how efficiently the body converts folic acid into the active form it can use. Methylated folate, known as 5-MTHF, is already in the active form, so it bypasses that conversion step. Research comparing the two forms supports 5-MTHF as a reliable way to raise folate status, including for people with reduced conversion capacity. WeNatal uses 5-MTHF for exactly this reason. Vitamin B12 follows the same logic, where the methylated form tends to be more usable than the cheaper, inactive version.

Why "included" and "included at a meaningful dose" are different

Form differences are often invisible unless you read the fine print. The same is true of dosage. A prenatal that technically contains choline but provides only 55 mg of it is delivering a small fraction of what research suggests during pregnancy. The adequate intake for choline in pregnancy is set at 450 mg per day, so a 55 mg dose covers very little ground. Having the nutrient and having enough of the nutrient are two different things. 

From preventing deficiencies to optimizing your nutrient stores

Here is the shift that changes how you read every label. Most conventional prenatals are dosed to prevent a deficiency, which means they aim for the minimum needed to keep levels from dropping too low. That is a worthwhile floor. It is not the same as helping you build the reserves your body actually draws on during conception, pregnancy, and recovery.

Think of it like a savings account rather than a daily allowance. Your body pulls from its nutrient stores during the earliest weeks of pregnancy, often before you even know you are pregnant, and again during the demanding months of postpartum recovery and breastfeeding. Entering that window with fuller stores gives your body more to work with from day one.

This is where dosage and form come back into the picture. Vitamin D is a good illustration. A double-blind randomized clinical trial found that 4,000 IU per day during pregnancy was safe and more effective than lower doses at helping women reach and maintain healthy vitamin D levels. A prenatal that provides 1,000 to 2,000 IU may help prevent a frank deficiency, while a dose aligned with that research is better positioned to help you actually maintain optimal levels. WeNatal is built around this difference. The higher, clinically informed dosages are meant to help you optimize nutrient stores, not simply clear the lowest bar. As always, the right vitamin D level for you is worth confirming with your provider, since individual needs vary.

WeNatal vs. Ritual

Ritual Essential Prenatal — 12 nutrients, bioavailable forms, lower dosages, roughly $39 per month.

Ritual has done a real service by bringing bioavailable nutrient forms to the mainstream prenatal market, and that genuinely deserves acknowledgment. Their capsules use the right forms of folate and B12, and the brand has built real trust around ingredient transparency.

The gap with WeNatal is mainly scope and dosage. Ritual's formula includes 12 nutrients, while WeNatal includes 24. The nutrients Ritual leaves out entirely include vitamins A and C, thiamine, riboflavin, B6, zinc, selenium, copper, manganese, molybdenum, inositol, and chromium. These are not obscure add-ons. Several of them, including zinc, selenium, B6, and inositol, are associated with reproductive and hormonal health.

On the nutrients Ritual does include, the dosages tend to sit below what WeNatal provides. Choline is the most dramatic example, at 55 mg in Ritual compared with 400 mg in WeNatal. Vitamin D is also lower at 2,000 IU compared with WeNatal's 4,000 IU, and magnesium, folate, B12, and vitamin E are all dosed more conservatively.

For someone who wants a minimal, clean, starter-level prenatal, Ritual is a reasonable product. For preconception support or a more comprehensive nutritional foundation during pregnancy, the formula leaves gaps that would need additional supplementation to fill.

WeNatal vs. Perelel

Perelel Prenatal — phase-based system, multiple products, roughly $49.50 per month for the women's formula.

Perelel takes an interesting approach by offering different supplement packs for different stages of pregnancy. The idea of tailoring nutrition to each trimester makes sense in theory, and it is a genuinely creative way to think about changing needs. In practice it also introduces more to manage, since you are moving between products throughout pregnancy, and the overall formula still lands below WeNatal on most key nutrients.

Compared with WeNatal for Her, Perelel offers lower doses of vitamins A, C, and D (2,000 IU vs. 4,000 IU), along with folate, B12, choline (120 mg vs. 400 mg), iron, magnesium, zinc, selenium, copper, chromium, and vitamin K. Choline in particular is included at less than a third of the amount in WeNatal.

WeNatal is formulated to be appropriate for every stage, from preconception through postpartum, without requiring any formula changes along the way. For many people, that simplicity is genuinely useful. There is less to think about, less to reorder, and less room for accidental gaps during a transition between packs.

Perelel's men's formula has its own gaps. It is missing thiamine, riboflavin, niacin, copper, acetyl L-carnitine, and NAC, and it includes CoQ10 at 50 mg compared with 200 mg in WeNatal for Him.

WeNatal vs. Bird & Be

Bird & Be Complete Prenatal for Females — 6 capsules per day, bioavailable forms, roughly $55 one-time or $49.50 subscription.

Bird & Be deserves real credit for using bioavailable nutrient forms and building a formula around fertility-focused ingredients. Their prenatal includes methylated folate and uses chelated minerals, which puts it ahead of many conventional options.

Where WeNatal pulls ahead is on key nutrient dosages. Vitamin D3 is 1,000 IU in Bird & Be compared with 4,000 IU in WeNatal. Choline is 150 mg compared with 400 mg. Magnesium is 20 mg compared with 100 mg. Zinc is 13 mg compared with 30 mg. These are the kinds of differences that separate technically containing a nutrient from providing it at a level that can actually move the needle.

Bird & Be's formula also omits vitamin K, and it uses a single alpha-tocopherol form for vitamin E, while WeNatal uses mixed tocopherols that provide four different forms: alpha, beta, gamma, and delta. Research generally suggests a broader spectrum of tocopherols offers more comprehensive benefit than a single isolated form.

There is also a practical consideration. Bird & Be requires 6 capsules per day compared with WeNatal's 3, which is a meaningful difference for anyone managing pregnancy nausea or supplement fatigue.

WeNatal vs. Needed

Needed Prenatal Multi — 3-pill or 8-pill options, high-quality bioavailable formula, roughly $49.99 one-time or $42.99 subscription.

Needed is one of the more thoughtfully formulated prenatals on the market. Their attention to bioavailable nutrient forms is evident, and the brand has earned a credible reputation in the functional nutrition space. The 3-capsule option makes it more practical than their original 8-pill version.

On dosing, WeNatal for Her provides higher amounts of vitamin A, vitamin C, folate, zinc, and chromium. Needed's formula also does not include iron, which is a meaningful omission given how common iron deficiency is among women of reproductive age and how quickly iron demands increase during pregnancy.

For the men's formula, the gap is wider. Needed for Him does not include acetyl L-carnitine, N-acetyl-L-cysteine (NAC), alpha lipoic acid, or CoQ10. CoQ10 is one of the more studied nutrients in male fertility research, so its absence is a notable distinction. WeNatal for Him also provides higher doses of vitamins C, E, niacin, biotin, zinc, and copper.

WeNatal vs. Thorne

Thorne Basic Prenatal — 3 capsules per day, established supplement brand, widely recommended by practitioners.

Thorne is a respected name in the supplement industry, and their Basic Prenatal is frequently recommended by practitioners who trust the brand's quality-control standards. The 3-capsule serving size is convenient, and the formula uses generally reliable ingredient forms.

The differences show up at the dosage level. Thorne's Basic Prenatal provides lower levels of vitamins A and D, and choline is either absent or well below meaningful levels. One formulation detail is worth noting: it includes both iron and calcium in the same capsule. These two minerals compete for absorption when taken together, which can mean you absorb less of each than the label suggests. WeNatal deliberately separates these to avoid that competition, and uses a gentle bisglycinate iron form that tends to be easier on the digestive system.

Molybdenum is also absent from Thorne's formula. It is a trace mineral, but one that plays a role in enzyme function and sulfite metabolism, which is particularly relevant for people with sensitivities to sulfite-containing foods.

For someone who already eats a very nutrient-dense diet and mainly wants foundational coverage, Thorne Basic Prenatal is a solid option. For preconception support or anyone with higher nutrient demands, the dosage gaps matter.

One consideration worth keeping in mind is the recently announced acquisition of Thorne by P&G. While this does not necessarily mean the products will change, acquisitions can sometimes lead to future updates in formulation, including shifts in nutrient forms or dosages. For that reason, it is always worth reviewing the Supplement Facts panel over time rather than assuming a formula will remain unchanged.

The full picture: how WeNatal stacks up across all five brands

A few patterns show up consistently across this comparison.

First, choline is chronically underdosed in most prenatal vitamins. The adequate intake in pregnancy is set at 450 mg per day, yet including a meaningful amount requires more capsule space and higher formulation costs, so many brands include a token amount or skip it. WeNatal's 400 mg is one of the highest amounts available in a 3-capsule prenatal. The evidence on choline is still developing, and we walk through it fairly in the research section below.

Second, vitamin D dosing across the board tends to lag behind where research has been moving. Most brands provide 1,000 to 2,000 IU. The randomized trial evidence supporting 4,000 IU per day for maintaining healthy levels in pregnancy is the dosage WeNatal uses.

Third, the iron-calcium combination is worth paying attention to. When both are in the same capsule, they compete for absorption, which means you may not be getting the full benefit of either nutrient. WeNatal formulates without calcium so that iron absorption is not compromised.

Note on this table: "Yes" means the product meets the standard. "Partial" means it partially meets it or meets it in some versions. "No" means the nutrient is absent or significantly underdosed. Individual product formulas can change, so always verify directly with the brand's current label.

What the research says about the four key nutrients

We want to be honest about the evidence, including where it is strong and where it is still emerging.

• Choline. The adequate intake during pregnancy is 450 mg per day. One randomized controlled feeding trial reported that prenatal choline supplementation was associated with better sustained attention in children at age 7. A 2025 systematic review took a more cautious view, concluding that current evidence is not yet strong enough to firmly confirm that higher prenatal choline improves child neurodevelopment. The takeaway is nuanced: choline plays a well-established role in the body, meeting the recommended intake is sensible, and the long-term outcome research is still developing.
• Vitamin D. A double-blind randomized clinical trial found 4,000 IU per day during pregnancy to be safe and effective for reaching and maintaining healthy vitamin D levels.
• Iron. A randomized controlled trial in pregnant women with iron deficiency found ferrous bisglycinate to be well absorbed and generally well tolerated. This is the gentle iron form WeNatal uses.
• Folate. Clinical pharmacokinetic research supports 5-MTHF as a reliable way to raise folate status, which is especially relevant for the large share of people with reduced folic acid conversion.

If you want to go deeper on the individual nutrients that support this stage, our overview of the essential nutrients for fertility, pregnancy, and postpartum is a useful next read.

Why prenatal nutrition should start before pregnancy

One thing worth understanding before you choose a prenatal: egg development begins roughly 90 days before ovulation. That means the nutrients circulating in your body during the three months before you try to conceive are already part of the environment supporting egg development. The same window applies to sperm production on the male side.

This is why many fertility specialists suggest starting a prenatal at least three months before you begin trying to conceive. Having fuller stores of folate, choline, vitamin D, and iron before pregnancy begins gives your body more to work with from the start, including during the early weeks before many people even know they are pregnant. This is the "optimize your stores" idea in action. You are not scrambling to catch up. You are entering the window prepared. For more on this, our article on why prenatal vitamins matter for fertility covers the preconception window in more detail.

A note for partners

At WeNatal, we believe men are 50% of the fertility equation, and the research on the preconception window applies to both partners. Sperm development follows a roughly 90-day cycle, which means the months before conception are an opportunity for both people, not just one. This is why we make a dedicated men's formula. WeNatal for Him is built around nutrients studied in male reproductive health, including CoQ10, which is among the more researched nutrients in this area. Preparing together, rather than leaving it to one partner, reflects how the science actually works.

When to talk to your healthcare provider

A prenatal comparison can help you understand your options, but it is not a substitute for personalized care. It is worth checking in with your provider if you:

• Have been diagnosed with an MTHFR variant or other genetic factor affecting nutrient metabolism
• Have a known deficiency, anemia, or a condition that changes your nutrient needs
• Take medications that may interact with vitamins or minerals
• Are unsure how much vitamin D, iron, or any other nutrient is right for you
• Have a history of pregnancy complications and want a tailored plan
• Experience ongoing digestive discomfort with your current supplement

Your provider can order bloodwork, interpret your individual levels, and help you build a plan that fits your body rather than a general recommendation.

Frequently asked questions

Is WeNatal better than Ritual? 

WeNatal for Her includes 24 nutrients compared with Ritual's 12, and provides higher dosages of choline (400 mg vs. 55 mg), vitamin D (4,000 IU vs. 2,000 IU), and several other key nutrients. Ritual uses quality bioavailable forms, but its formula is less comprehensive and may leave nutritional gaps for people in preconception or pregnancy. The best choice depends on your individual needs, which your provider can help you assess.

How does WeNatal compare to Perelel? 

Perelel uses a phase-based system with different products for each stage of pregnancy, while WeNatal uses a single formula appropriate from preconception through postpartum. Across most nutrients, including choline, vitamin D, folate, and zinc, WeNatal provides higher dosages. Perelel's women's formula includes choline at 120 mg, compared with 400 mg in WeNatal.

What makes WeNatal different from Bird & Be? 

Both brands use bioavailable nutrient forms, but WeNatal provides substantially higher amounts of vitamin D (4,000 IU vs. 1,000 IU), choline (400 mg vs. 150 mg), magnesium (100 mg vs. 20 mg), and zinc (30 mg vs. 13 mg). WeNatal also includes vitamin K2 and uses mixed tocopherols for vitamin E, while Bird & Be uses a single alpha-tocopherol form. Bird & Be requires 4 capsules per day, while WeNatal requires 3.

Does the Needed prenatal include iron? 

Needed's prenatal formula does not include iron. WeNatal for Her includes 18 mg of iron in the gentle bisglycinate chelate form, which tends to be easier to tolerate than many conventional iron forms.

Why does WeNatal include 4,000 IU of vitamin D when most prenatals include much less? 

Vitamin D insufficiency is common among women of reproductive age, particularly at northern latitudes or with limited sun exposure. A randomized clinical trial found that 4,000 IU per day during pregnancy was safe and effective for maintaining healthy blood levels. WeNatal's formula reflects this research direction. Individual needs vary, so dosing is worth discussing with your provider.

When should you start taking a prenatal vitamin? 

Many fertility specialists suggest starting at least three months before you begin trying to conceive. This window aligns with the period when egg and sperm development is underway, giving your body time to build fuller nutrient stores before conception.

A note on supplements and diet

Prenatal vitamins are designed to fill nutritional gaps, not to replace the foundation that food provides. A diet rich in vegetables, quality proteins, healthy fats, and whole grains supplies fiber, phytonutrients, and compounds no supplement can fully replicate. The goal is to use a well-formulated prenatal alongside a nutrient-dense diet, not instead of one.

That said, the research is consistent that many people enter pregnancy with suboptimal levels of choline, vitamin D, iron, and folate even when eating well. Modern food systems, dietary restrictions, increased nutrient demands during pregnancy, and individual genetic differences all contribute to common gaps. A prenatal that includes these nutrients at meaningful dosages, in forms the body can actually absorb and use, is a practical part of supporting both parent and baby through this window.

If you have specific health conditions, are managing an MTHFR variant, or have been found deficient in particular nutrients, working with your healthcare provider to personalize your routine will always be more effective than a one-size-fits-all approach.

A note from WeNatal on choosing your prenatal

Choosing a prenatal is not about finding a perfect product or getting everything exactly right. It is about giving yourself, and your future family, a strong nutritional foundation during a window that genuinely matters.

Every brand in this prenatal vitamin comparison is trying to support that goal, and several make real contributions to the space. What sets WeNatal apart is a formula built to do two jobs at once: help fill the common nutritional gaps and help you build your nutrient stores, using evidence-informed dosages and bioavailable forms in just three capsules a day. We also believe this is a shared journey, which is why we make formulas for both partners.

Wherever you are in your path, from thinking about conception to holding a newborn, small and consistent steps add up. If you are ready to build that foundation, you can explore WeNatal for Her and WeNatal for Him, and as always, bring any questions to your healthcare provider so your plan fits you.
