Beli sells prenatal vitamins at around $50 a month, and — unusually — a parallel fertility formula for men. Treating conception as something both partners prepare for is the right framing and most of the category ignores it. For readers here there is a bigger point behind it: if you are losing weight, you may already be doing more for fertility than any supplement will.
The Medication Timeline Comes First
GLP-1 medications are not for use in pregnancy, with guidance to discontinue one to two months before attempting conception. They also reduce oral contraceptive absorption — tirzepatide’s label requires a barrier method for four weeks after starting and after each dose escalation.
If you are buying a prenatal while taking one of these medications, that sequencing is the conversation to have before the supplement conversation. Our contraception review covers it, and FullWell covers the preconception nutrition case in more depth.
Including Men Is the Distinctive Part
Beli sells a men’s fertility formula alongside the prenatal. Sperm quality contributes to roughly half of fertility outcomes and sperm take around three months to develop — so the preconception window applies to both partners equally.
That framing is correct and under-served. Preconception advice is overwhelmingly directed at women, and a brand that builds a parallel product for men is addressing a real gap rather than inventing a market.
We would be more measured about the evidence than the framing. Antioxidants and micronutrients for male fertility have been studied, and the trials are mostly small with inconsistent results on outcomes that matter — live births rather than semen parameters. Correcting a genuine deficiency plausibly helps; supplementing an adequately nourished man probably does less.
Weight Loss Does More for Fertility Than Any Supplement
This is the part worth reading if you are on this site rather than a fertility one.
For women, weight loss can restore ovulation, particularly in PCOS — one of the most common causes of anovulatory infertility. That is a substantially larger effect than any micronutrient produces, and it is a documented reason people conceive unexpectedly on these medications after years of assuming they could not.
For men, excess weight is associated with poorer semen parameters and altered hormone profiles, and weight loss improves several of those markers. Again, larger than what a capsule offers.
So the honest hierarchy for a couple planning conception is: sort the medication timeline, keep the weight loss, protect protein and nutrient intake during it, and add a prenatal for the folate. Beli is a reasonable choice for that last step, not the first one.

Price
At around $50 a month Beli sits below FullWell at $59 to $70 and well above supermarket prenatals, which cost a fraction as much. Reviewers note the price as the main reservation while generally rating the products positively.
Worth saying plainly: any prenatal with adequate folate is far better than none, and the marginal benefit of a premium formulation over an adequate one is much smaller than the marginal benefit of taking one at all. If $50 a month for two people is a stretch, buy the cheaper one and take it consistently.
Pros and Cons
Pros
- Parallel men’s formula — an under-served and legitimate gap
- Preconception nutrition is genuinely evidence-backed for folate
- Positive independent and customer assessments of ingredient quality
- Cheaper than the premium end of the prenatal market
- Fewer capsules than research-dosed alternatives, aiding adherence
- Particularly relevant after a period of much-reduced intake
Cons
- $50 a month, or $100 if both partners take it
- Male fertility supplement evidence is small and inconsistent
- Individual nutrient amounts not published in sources we could verify
- Weight loss itself does more for fertility than any of this
- Irrelevant unless you are planning a pregnancy
- Cheaper prenatals meet requirements adequately
Who Should Use It, and Who Should Not
Beli suits you if you are planning a pregnancy, you want both partners covered, and you prefer a manageable capsule count to a research-maximalist regimen. Start it in the months before trying, which is when preconception nutrition actually matters.
Look elsewhere if budget is tight — an adequate prenatal taken consistently beats a premium one you ration — or if you want research-level dosing, where FullWell goes further at the cost of eight capsules a day. And if you are currently on a GLP-1, the timeline conversation comes before either.
Limitations of This Review
This review is based on retailer listings and independent coverage checked on 7 August 2026. We could not establish individual nutrient amounts for either formulation — for a prenatal the folate and iron figures are what matter, so check the label — nor allergens, capsule counts or refund terms. Statements about fertility, weight and GLP-1 pregnancy guidance describe established findings and prescribing guidance rather than claims about this product. We have not taken it, and nothing here is fertility or obstetric advice.
Frequently Asked Questions
Should men take a fertility supplement too?
Sperm quality contributes to roughly half of fertility outcomes and takes around three months to turn over, so the preconception window applies to both partners. Whether a supplement is the right intervention is a separate question — for men carrying excess weight, weight loss itself has better evidence.
Can I take this while on a GLP-1?
A prenatal is not the problem — the medication is. GLP-1s are not for use in pregnancy and guidance is to discontinue one to two months before attempting conception. Sort that timeline with your prescriber before anything else.
How much does it cost?
About $50 a month for a 30-day supply direct from the company, with a small subscription discount.
Does losing weight improve fertility?
For many people yes — weight loss can restore ovulation, particularly with PCOS, and improves several male fertility markers. That is worth knowing in both directions, because it also means conception can happen sooner than expected.
Verdict
3.3 / 5
A well-regarded prenatal with the right instinct about men — sold into a situation where the weight loss you are already doing matters more than the capsules.
Preconception folate is one of the few places where supplementation demonstrably prevents harm, and treating conception as a two-person nutritional project is a framing the category mostly gets wrong. Beli does both at a price below the premium end.
For readers here, keep the hierarchy straight. Sort the GLP-1 timeline with your prescriber, understand that weight loss may have made you more fertile than you expect, protect your protein and nutrient intake, and then add a prenatal for the folate. Beli is a fine choice for that last step, and any adequate prenatal taken consistently would also do.

Both Partners, and the Timeline First
Sperm take three months to develop, so the preconception window applies to both of you — and GLP-1s need to stop one to two months before trying.
