Beli Review: The Men’s Test Doesn’t Measure Sperm

Name: Beli Review
Item: Beli
Rating: 3.2
Author: GLP1Drugs.org

Beli sells prenatal and preconception supplements for women and men from $50, plus at-home fertility tests at $149. The category is genuinely relevant to readers here, because these medications make unplanned pregnancy more likely and folate cannot be taken retrospectively. But their men's supplement promises to support sperm count, motility and morphology while their men's test measures none of those three — and we are paid a 60% commission on all of it.

Our commission on this offer is 60%

Sixty per cent — roughly $30 of a $50 bottle comes to us. That is the highest rate of any offer we have reviewed, and it is worth understanding what a number like that implies. A company can only pay away sixty per cent of revenue if the marketing margin is the majority of the price, which means you are paying substantially for distribution rather than for what is in the capsule. Everything below should be read with that in view, including the section where we tell you the cheap alternative is the one the clinical trials actually used.

Our Verdict

Beli · belibaby.com · $50–$149

3.2 / 5

The men’s test measures hormones; the men’s supplement promises sperm

Beli Vitality for Men is sold on supporting healthy sperm production, motility and morphology. The $149 Men's Fertility Test is described as providing insights into testosterone, FSH and LH levels to help you understand your sperm potential. Those three sperm parameters are measured by looking at semen, and no hormone panel is a substitute. So the test sold alongside the supplement does not measure any of the outcomes the supplement is sold on — which means it cannot tell you whether the supplement worked.

No doses published anywhere we looked

The prenatal page names methylfolate, choline, iodine, zinc, iron, magnesium and vitamins B6, B12, C, D, E and K2 — a sensible list. It gives not one quantity. No micrograms, no mcg DFE, no supplement facts panel on the page we read. For a prenatal the folate amount is the whole clinical point, and optimal levels of methylfolate is a phrase rather than a dose. Ask for the panel before you buy.

“More superior” than folic acid overstates it

Their page describes methylfolate as a natural and more superior form of folic acid. Methylfolate is well absorbed and needs no conversion, which is a real argument for it. But every landmark trial and every fortification programme underpinning neural tube defect prevention used folic acid — which is why guidance names folic acid specifically. Methylfolate is a reasonable choice; calling it superior implies an outcome advantage nobody has demonstrated for the thing that matters most.

The women’s test is sold as assessing “fertility potential”

It is described as giving a picture of your egg supply, helping you assess your fertility potential. Tests of this kind generally measure anti-Müllerian hormone, which is genuinely informative about ovarian reserve and about how ovaries will respond to IVF stimulation. It is a poor predictor of natural conception or how long it will take — and professional bodies have repeatedly cautioned against using it to counsel women about their reproductive potential, which is close to the use being marketed.

The category genuinely matters on a GLP-1 — the price does not

Neural tube closure completes within about the first month of pregnancy, often before anyone knows. These medications raise the chance of an unplanned pregnancy — fertility returns as weight falls, especially in PCOS, and tirzepatide's label warns it may reduce oral contraceptive efficacy. So baseline folate matters more for this readership than for most. It does not need to cost $50: 400 micrograms of folic acid is a few dollars a month, in the exact form the trials used.

A men’s test that measures no sperm parameter

Why folate is the one thing this readership should not skip

The logic runs through timing, and it is worth setting out properly because it is the strongest argument on this page. The neural tube — the structure that becomes the brain and spinal cord — closes within roughly the first four weeks after conception. That is frequently before a person knows they are pregnant. Which means folate taken after a positive test is taken after the window in which it does the most good has already closed. This is precisely why guidance recommends 400 micrograms of folic acid daily for everyone who could become pregnant, rather than only for those actively trying.

Now put that next to what these medications do. Weight loss frequently restores ovulation, especially in polycystic ovary syndrome where anovulation is a defining feature and weight reduction is a first-line intervention — so somebody who had come to assume conception was difficult may find that has quietly changed. And tirzepatide's labelling warns that it may reduce the effectiveness of oral hormonal contraceptives, advising a non-oral method or an added barrier method for four weeks after starting and after each dose increase. Fertility going up while the reliability of the pill goes down is the combination behind the press coverage of unexpected pregnancies on these drugs.

So this readership sits in an unusual position: at elevated risk of an unplanned pregnancy, and therefore in the group for whom baseline folate has the most value, precisely because it cannot be applied retrospectively. That is a genuinely strong reason to be taking it — and it is the strongest thing we can say for a preconception supplement of any kind. It is not a reason to spend $50 a month. Four hundred micrograms of folic acid costs a few dollars, and it is the exact synthetic form on which the entire evidence base rests.

There is a sequencing point that nobody joins up, and it belongs to whoever prescribes your medication rather than to a supplement company. If you are planning a pregnancy, semaglutide's labelling advises discontinuing at least two months beforehand because the drug clears slowly, and these medicines are not recommended in pregnancy or while breastfeeding. Meanwhile folate ideally starts at least a month — often advised as three — before conception. Those two clocks have to be run together, which means the conversation has to happen before you start trying rather than after. Raise it as a specific item at your next appointment.

One safety note on prenatal shopping generally, since it is the kind of thing this readership is now buying. High doses of preformed vitamin A — retinol, as opposed to beta-carotene — are teratogenic, and prenatal formulations are designed around that. Do not stack a general multivitamin, a separate vitamin A supplement and a prenatal without checking the totals, and do not assume more of everything is better. If you are also using a topical or oral retinoid for skin, that is a separate conversation to have with your prescriber, because oral retinoids in particular are contraindicated in pregnancy.

Want a prenatal that does publish its numbers?

We reviewed FullWell Fertility separately and rated it 3.4. We criticised it on other grounds, but on the two points where Beli falls short it is the better example in this category: FullWell publishes full supplement facts panels and states that it third-party tests every lot it produces for contaminants including heavy metals, pointing customers to results for the most recent lot. That is what a dose disclosure and a testing claim look like when a company decides to make them. Read our FullWell Fertility review.

Prices and product descriptions from belibaby.com, retrieved 12 August 2026. Our read is an assessment of the marketing claims against the general evidence base, not advice about your care — what supplements or tests are appropriate for you is a question for your clinician, particularly if you are planning a pregnancy or taking other medication.

What we verified

1. The test that cannot check the supplement

Set the two men's products side by side, in Beli's own words. The supplement: boost sperm health and fertility with our specially formulated men's prenatal vitamin, featuring a precise blend of essential nutrients to support healthy sperm production, motility and morphology. The test: provides personalized insights into your testosterone, FH and LH hormone levels to help you understand your sperm potential.

Count, motility and morphology are the three headline parameters of a semen analysis, and a semen analysis is what measures them — a laboratory looking at a sample. Testosterone, FSH and LH are pituitary and gonadal hormones. They are genuinely informative about the hormonal axis and can point towards particular causes of male infertility, so this is not a useless test. But it does not measure sperm, and describing it as revealing sperm potential invites a reader to think it does. The practical consequence is neat and unfortunate: a man could buy both products, take the supplement for six months, retest, and learn nothing about whether the three things he was sold had changed.

We should be fair about the limits of what we checked. We read the product descriptions from the store's own catalogue and did not open the full test page, so if the men's test also includes a semen component, it exists somewhere we did not look — and if so, the description we read badly undersells it. We also note the description as written contains FH rather than FSH, which we take to be a typo. Either way, the fix is the same for a buyer: if you want to know your sperm count, motility and morphology, ask for a semen analysis, which a urologist or fertility clinic will arrange.

2. Doses, forms, and what a prenatal is actually for

The nutrient list on their prenatal page is a reasonable one for the category: methylfolate, choline, iodine, zinc, iron, magnesium and vitamins B6, B12, C, D, E and K2. Choline in particular is a sensible inclusion that many prenatals skip and which is genuinely under-consumed in pregnancy. The capsule format is also justified with a real argument — that it is gentler on the stomach, which matters when morning sickness makes large tablets intolerable.

What is absent is any number. We searched the page for micrograms, for a mcg DFE folate figure, and for a supplement facts panel, and found none of them — the strongest statement is optimal levels of methylfolate. For most products a missing dose is a transparency irritation. For a prenatal it is the central fact, because the reason to take one at all is hitting a specific folate target during a specific window. A buyer cannot compare this against a $6 alternative without the number, which is arguably the point.

On the form, their page calls methylfolate a natural and more superior form of folic acid. Methylfolate is the biologically active form and bypasses a conversion step, which is a genuine advantage for people carrying certain MTHFR variants and a reasonable formulation choice generally. But the trials that established folate's effect on neural tube defects, and the national fortification programmes that followed them, used folic acid. That is why guidance specifies folic acid by name and by dose. Superior is doing work the evidence does not support, and a reader with a family history of neural tube defects should be taking that question to a clinician rather than to a product page — the recommended dose in that situation is higher and is a medical decision.

3. What a 60% commission tells you

We have disclosed rates from one per cent to three hundred dollars across this series. Sixty per cent of the sale price is a different thing again, and it is worth explaining what it implies rather than simply flagging it. A business can only afford to hand away sixty per cent of revenue if the cost of the physical product is a small fraction of the price — which is normal for supplements, where the capsules are cheap and the expensive part is persuading somebody to buy them. You are paying, in the main, for distribution.

That does not make it a bad product, and it is not evidence of anything about the formulation. Plenty of well-made things carry high marketing margins. But it does mean a reader should be sceptical of enthusiastic coverage of this category generally, because sixty per cent is enough to make writing enthusiastically about it extremely rewarding. We would rather tell you the number and let you weigh our conclusions against it than bury it in a footer and let you assume good faith.

For completeness on the company: the products are described as vegan friendly, non-GMO, made in the USA and produced under cGMP guidelines, and the range includes a lactation product at $55, a couples bundle at $90 and a preconception booster at $55. cGMP is a manufacturing standard about consistency and hygiene rather than efficacy, and it is a baseline expectation rather than a distinguishing feature. We found no third-party testing or certification claim on the page we read, which for a product taken daily during pregnancy is the thing we would most want to see.

In its favour

Addresses a category that genuinely matters, and matters more for this readership than most.
Uses methylfolate, a well-absorbed form, and includes choline and iodine, which many prenatals omit.
Capsule format justified with a real argument about tolerability during morning sickness.
Products for men as well as women, which reflects that fertility is not solely a female matter.
Transparent per-product pricing published openly, with no quiz gate and no forced subscription visible.

Against it

The $149 men's test measures hormones, not the sperm parameters the $50 men's supplement is sold on.
Not a single nutrient dose published on the page we read — no micrograms, no supplement facts panel.
Methylfolate described as a more superior form of folic acid, which overstates the evidence.
The women's test is sold as assessing fertility potential, a use professional guidance cautions against.
No DHA and no third-party testing claim found on the product page.
At $50 a month it is many times the cost of the folic acid the evidence base actually used.
Our 60% commission is the highest on this site and should temper any enthusiasm, including ours.

Our verdict: 3.2 out of 5

The right category at the wrong price, with a men's test that cannot verify the men's supplement — take the folate, skip the $149.

The case for a preconception supplement is real, and for this readership it is stronger than for most. The neural tube closes inside the first month, often before a pregnancy is known, which is why folate is recommended to everyone who could conceive rather than only to people trying. And these medications specifically raise the odds of an unplanned pregnancy — fertility returns as weight falls, particularly in PCOS, and tirzepatide's own labelling warns it may reduce the effectiveness of oral contraception. If you could become pregnant and you are on one of these drugs, you are in the group for whom baseline folate has the most value.

None of which requires $50 a month. Four hundred micrograms of folic acid costs a few dollars, and folic acid is the precise synthetic form on which the entire evidence base was built — the trials, the fortification programmes, the guidance. Beli's prenatal uses methylfolate, which is a perfectly reasonable choice and better absorbed, but their page calls it a more superior form of folic acid, and that claims an outcome advantage nobody has shown for the thing that matters. If you can afford the designer version and prefer the capsule, that is a legitimate purchase. It is not a clinical necessity, and the cheap bottle is not a compromise.

The formulation is otherwise sensible — choline and iodine included, which many prenatals skip — and let down by the absence of any numbers. We could not find a single dose on the page we read: no micrograms, no folate figure, no supplement facts panel. For most products that is an irritation. For a prenatal it is the central fact, because the whole reason to take one is hitting a specific target in a specific window, and without the number you cannot compare it to anything. We also found no DHA and no third-party testing claim, which is what we would most want to see on something taken daily throughout a pregnancy.

The sharpest problem is on the men's side and it is structural. The supplement is sold on supporting sperm count, motility and morphology. The $149 test alongside it is described as measuring testosterone, FSH and LH. Those are useful hormones and they are not sperm — count, motility and morphology come from a semen analysis. So a man can buy both, take the capsules for six months, retest, and learn nothing about the three outcomes he was sold. If you want those numbers, ask a urologist or fertility clinic for a semen analysis. And on the women's test, ovarian reserve markers are genuinely useful for planning IVF and poor at predicting natural conception, which is not how assess your fertility potential reads.

Three-point-two, and one number to hold on to: we are paid sixty per cent of whatever you spend here, the highest rate anywhere on this site. A company can only pay that away if most of the price is marketing rather than contents. So here is the version that costs us the most and is the most useful: if you could become pregnant while taking a GLP-1, start taking folate now, at whatever price point you like, including the cheapest. If you are planning a pregnancy, ask your prescriber about the two-month washout advised for semaglutide and coordinate it with starting folate at least a month ahead. And if fertility is a real question rather than a precaution, spend the $149 on a clinician who can order the right test instead.

Frequently asked questions

What is Beli and what does it cost?

A prenatal and preconception supplement company selling products for both women and men. Checked 12 August 2026: Prenatal for Women $50, Beli for Men and Beli Vitality for Men $50, Preconception Boost $55, Breastfeeding Lactation Support $55 or $132, a Fertility Bundle for Couples $90, and at-home fertility tests for men and women at $149 each. The supplements are described as vegan friendly, non-GMO, made in the US and produced under cGMP guidelines.

How much do you earn from this?

Sixty per cent. That is not a typo and it is the highest commission rate of any offer we have reviewed — roughly $30 on a $50 bottle. A rate that high tells you something about how a product is priced: the marketing margin is the majority of what you pay. We are disclosing it in the first section rather than the last because the rest of this review recommends cheaper alternatives, and you should be able to weigh that against what we stand to make.

Is the folate in it good?

The form is sensible and the dose is not stated. Their page says the prenatal contains methylfolate, which is a bioavailable form and a reasonable choice, alongside choline, iodine, zinc, magnesium, iron and vitamins B6, B12, C, D, E and K2. But we could not find a single quantity anywhere — no micrograms, no mcg DFE figure, no supplement facts panel on the page we read. For a prenatal vitamin the folate amount is the clinically decisive fact, and optimal levels is not a number.

They call methylfolate a superior form of folic acid. Is that right?

It overstates it. Methylfolate is well absorbed and does not require conversion, which is a genuine argument for it, particularly for people with certain MTHFR gene variants. But the entire evidence base for preventing neural tube defects — the landmark trials and the food fortification programmes built on them — used folic acid, the synthetic form. That is why public health guidance specifies folic acid by name. Methylfolate is a fine choice; describing it as more superior implies an outcome advantage that has not been demonstrated for the thing that matters most.

What's missing from the formula?

DHA, as far as we could tell. The omega-3 fatty acid DHA is commonly recommended during pregnancy for fetal brain and eye development, and many prenatals either include it or tell you to take it separately. We found no mention of DHA on the product page we read, and no third-party testing claim either. Neither absence is disqualifying — plenty of good prenatals omit DHA because it makes capsules large — but both are things to ask about before paying $50 a month.

What is wrong with the men's fertility test?

It does not measure the things the men's supplement promises to improve. Beli's men's product is sold on supporting healthy sperm production, motility and morphology. Their $149 Men's Fertility Test is described as providing insights into testosterone, FSH and LH hormone levels to help you understand your sperm potential. Hormones are not a semen analysis. Count, motility and morphology are measured by examining semen, and no hormone panel substitutes for that. If the test does include a semen component, the description we read does not say so — and if it does not, sperm potential is the wrong phrase for it.

And the women's fertility test?

Treat the interpretation carefully. It is described as giving a picture of your egg supply at any point in time, helping you assess your fertility potential. Tests of this kind typically measure anti-Müllerian hormone, which does correlate with ovarian reserve and is genuinely useful for predicting how ovaries respond to IVF stimulation. What it predicts poorly is natural fertility — whether and how quickly you will conceive without assistance. Professional guidance has repeatedly cautioned against using it to counsel women about their reproductive potential, which is close to what this product is sold as doing.

Why does folate matter especially on a GLP-1?

Because of when neural tube defects happen and when pregnancies are discovered. The neural tube closes within roughly the first month of pregnancy, frequently before anyone knows they are pregnant, which is why guidance recommends 400 micrograms of folic acid daily for everyone who could become pregnant rather than only those trying. And these medications raise the chance of an unplanned pregnancy specifically: fertility often returns as weight falls, particularly in polycystic ovary syndrome, and tirzepatide's labelling warns it may reduce the effectiveness of oral contraceptives. Higher chance of an unplanned pregnancy is exactly the case where preconception folate cannot be taken retrospectively.

Do I need a $50 prenatal to get that?

No, and this is the part that costs us the most. Four hundred micrograms of folic acid is available in a basic prenatal or as a standalone tablet for a few dollars a month, and the neural tube evidence was built on exactly that cheap synthetic form. If you can afford a $50 designer prenatal and prefer it, that is a legitimate choice for texture, tolerability and formulation breadth. But nobody should conclude from this page that adequate folate requires spending $50 a month, because it does not, and the cheap version is the one the trials used.

Take the folate. Ask for the panel.

If you could become pregnant on a GLP-1, start folate now at any price point — 400 mcg of plain folic acid is a few dollars and is the form the evidence used. If you buy here, ask for the supplement facts panel first, because no doses are published. And if fertility is a real question, ask a clinician for a semen analysis or the right hormone workup rather than buying a $149 kit. We are paid 60%.

Medical disclaimer

This article is informational and is not medical advice. Decisions about supplements, doses and fertility testing before or during pregnancy should be made with a clinician who knows your history — folate requirements are higher for people with a previous pregnancy affected by a neural tube defect, and for some people on particular medications, and that is a medical decision rather than a shopping one. Dietary supplements are not FDA-approved and are not reviewed for effectiveness before sale. High doses of preformed vitamin A (retinol) are teratogenic; do not combine multiple supplements without checking total intakes. GLP-1 receptor agonists are not recommended during pregnancy or breastfeeding, and semaglutide labelling advises discontinuation at least two months before a planned pregnancy; tirzepatide labelling warns of reduced oral contraceptive efficacy and advises a non-oral or additional barrier method for four weeks after initiation and each dose escalation. If you are pregnant, may be pregnant, or are planning a pregnancy while taking any of these medicines, contact your prescriber promptly. At-home fertility tests do not diagnose infertility; persistent difficulty conceiving warrants assessment by a clinician.

Katalys offer listing #1310, retrieved 12 August 2026 — 60.00% commission, NET 80 payment terms. The advertiser describes Beli as a modern men's and women's prenatal company whose products are vegan friendly, non-GMO, made in the US and produced following cGMP guidelines.
Neural tube closure is complete within approximately the first four weeks after conception, frequently before pregnancy is recognised, which is the basis for guidance that all people capable of becoming pregnant take 400 micrograms of folic acid daily rather than only those actively planning a pregnancy. The evidence base for folate in neural tube defect prevention, including the randomised trials and subsequent national food fortification programmes, was established using folic acid, the synthetic form. Higher doses are recommended where a previous pregnancy has been affected by a neural tube defect, which is a clinical decision.
5-methyltetrahydrofolate (methylfolate) is the biologically active folate form and does not require reduction by dihydrofolate reductase, which is the rationale for its use, particularly in individuals with reduced-function MTHFR variants. It has not been shown to be superior to folic acid for neural tube defect prevention.
Sperm concentration, motility and morphology are assessed by semen analysis. Serum testosterone, FSH and LH characterise the hypothalamic-pituitary-gonadal axis and can indicate causes of impaired spermatogenesis but do not measure sperm parameters. Anti-Müllerian hormone correlates with ovarian reserve and predicts ovarian response to controlled stimulation, but is a poor predictor of natural fecundity and time to spontaneous conception, and professional guidance has cautioned against its use to counsel individuals about their reproductive potential.
Preformed vitamin A (retinol) is teratogenic in high doses, which is why prenatal formulations limit it and why stacking supplements without checking total intake carries risk. Oral retinoids are contraindicated in pregnancy. Dietary supplements sold in the United States are not approved by the FDA before marketing, and cGMP addresses manufacturing consistency rather than clinical effectiveness.

Limitations, stated plainly. We did not buy or take any product, use either fertility test, or examine any physical supplement facts panel, and we make no assessment of the quality, purity or potency of anything sold here. We read the store's product catalogue and one product page; we did not open the full pages for either fertility test, so if the men's test includes a semen analysis component in addition to the hormones named in its description, it was not in what we read — and the criticism we make of that description would then be a criticism of the description rather than of the test. We could not obtain any nutrient dose, so we cannot tell you how much folate, choline or iodine any product contains, nor compare it with alternatives. We did not verify the cGMP, vegan, non-GMO or made-in-USA claims. We could not reach independent review platforms. We did not contact Beli before publishing.
