Does O Positiv MENO Help With Weight or Bloating?

WonderBiotics vs O Positiv MENO: Which Fits Weight, Bloating, and Appetite Concerns?

O Positiv MENO is a hormone-free capsule built around black cohosh, chasteberry, and ashwagandha for hot flashes, night sweats, and mood swings.¹ It contains no probiotics and isn't marketed for weight, bloating, or appetite; O Positiv itself sells that concern under a separate product, URO Metabolism + Probiotic, which the brand says replaced its earlier MOTO capsule.⁴ WonderBiotics Probiotics for Weight Management is built specifically around that second list.

What's Actually in O Positiv MENO?

MENO's capsule and gummy formulas aren't identical. Per two capsules: vitamin D3 (15 mcg), vitamin B6 (2 mg), chromium picolinate, ashwagandha KSM-66® root extract (300 mg), chasteberry fruit extract (40 mg), and black cohosh root extract (40 mg). Per two gummies: the same vitamin D3, vitamin B6, chasteberry, and black cohosh amounts, but ashwagandha KSM-66® drops to 150 mg and chromium picolinate isn't included.¹ O Positiv describes it as a "hormone-free menopause supplement for multi-symptom relief," targeting hot flashes, night sweats, mood swings and stress, and occasional sleeplessness. The brand advertises it as the top-selling menopause supplement at Target, with over a million bottles sold.² A one-time bottle (60 capsules, a 30-day supply) runs $41.99, or $34.99/month on subscription.¹

"Hormone-free" here means no estrogen, progesterone, or other hormones in the formula (more on what that claim does and doesn't mean below).

MENO's label, ingredient panel, and O Positiv's own product description don't mention weight, bloating, appetite, calorie burn, or GLP-1 anywhere.^{1, 2} A few customer reviews on the page happen to mention weight loss, but that's not a claim O Positiv makes about the product.

Why MENO Isn't Built for Weight, Bloating, or Appetite

O Positiv's own product lineup backs that up: the metabolism-and-appetite concern lives in a separate product, and it isn't MENO.

O Positiv previously sold MOTO, a stimulant-forward metabolism capsule built around EGCG from green tea extract (270 mg), chromium picolinate (600 mcg), black cumin seed extract (200 mg), and vitamin B12, with no probiotics or herbal menopause ingredients.³ The brand has since replaced it with URO Metabolism + Probiotic, which is closer to WonderBiotics' territory. One capsule combines vitamin B12, chromium picolinate (600 mcg), 100 mg of caffeine, green coffee bean extract, L-theanine, and three probiotic species: Bifidobacterium lactis (branded B. lactis Fit™), Lactobacillus gasseri, and Akkermansia muciniphila.⁴ O Positiv markets URO for "healthy weight management," appetite control, calorie burn, and bloating relief, and calls B. lactis Fit™ "clinically-studied" for fat reduction, though the product page doesn't link a specific study for the finished capsule.⁴

The strain has been tested in humans, just not in this exact formula. A 2024 randomized, double-blind, placebo-controlled trial gave 99 women with a BMI of 25–30 either at least 5 billion CFU/day of B. lactis IDCC 4301 (B. lactis Fit™) or placebo for 12 weeks.⁵ Total fat mass dropped more with the probiotic than placebo (−0.45 kg vs. −0.16 kg, P=0.0407), as did trunk fat (P=0.0200) and triglycerides (P=0.0088); the abstract also notes a larger fat-loss difference in the postmenopausal subgroup, though it doesn't report a p-value for that comparison, so it should be treated as exploratory.⁵ Several of the paper's authors are current or former employees of Ildong Bioscience, the strain's manufacturer, which also funded the trial.⁵ This is the single-strain trial, not a test of the four-way URO capsule with caffeine and green coffee bean extract layered on top, and it isn't a menopause-specific trial either.

If weight, appetite, or bloating is your main concern, O Positiv's own answer isn't MENO. It's URO, working through caffeine and chromium plus a standalone probiotic strain, sold as its own product.

How Strong Is the Evidence Behind MENO's Own Ingredients?

For the concerns MENO is actually built for, hot flashes, night sweats, and mood, the evidence on its lead ingredients is mixed.

Black cohosh is the most-studied herb in the formula, and the review-level evidence doesn't agree with itself. A 2012 Cochrane analysis of 16 randomized trials in 2,027 women found insufficient evidence that black cohosh reduces hot flash frequency compared with placebo.⁷ NIH's Office of Dietary Supplements cites a later 2016 meta-analysis reaching the same conclusion, and notes that both the American College of Obstetricians and Gynecologists and the North American Menopause Society have said the data don't support these supplements as effective for vasomotor symptoms.⁶ A more recent 2023 pairwise meta-analysis of 22 studies in 2,310 women reached the opposite conclusion, reporting significant improvement in overall menopausal symptoms and hot flashes with black cohosh versus placebo.¹⁴ The same NIH fact sheet also flags roughly 83 worldwide case reports of liver injury associated with black cohosh use, while adding there's no proven causal link, and that contamination of some products hasn't been independently confirmed.⁶ MENO's label lists a plain 40 mg root extract without a named standardized formulation, so it isn't clear which of these trial results, if any, it's most comparable to.¹

Ashwagandha KSM-66® is the highest-dose ingredient in MENO (300 mg). A randomized, double-blind, placebo-controlled trial, published online in January 2026, gave 60 women aged 45–55 either 600 mg/day of KSM-66 (300 mg twice daily) or placebo for 56 days, and found significant reductions in total Menopause Rating Scale scores and hot flash counts versus placebo.⁸ The authors reported no financial funding or competing interests, though the ingredient's manufacturer, Ixoreal Biomed, supplied the KSM-66 extract used in the study. The trial also used twice the daily ashwagandha dose in MENO's capsules (600 mg vs. 300 mg) and four times the dose in MENO's gummies (600 mg vs. 150 mg).⁸

Chasteberry has the thinnest evidence base of the three. A 2009 review of the pharmacology and clinical research on chasteberry for menopause concluded that rigorous randomized trial evidence for the herb on its own was lacking at that point.⁹ A smaller randomized, double-blind trial published in 2019, in 52 menopausal women given chasteberry extract for 8 weeks, later found significantly lower total menopausal symptom, anxiety, and hot-flash scores than placebo, though somatic complaints, depression, and sexual function didn't differ between groups.¹⁵

Individual response to any of these ingredients varies, and O Positiv's page doesn't claim the finished MENO formula itself has been through a clinical trial.¹ Ashwagandha has the clearest positive signal, at two to four times MENO's actual dose depending on capsule or gummy; chasteberry has a positive small trial but a thin overall base; and black cohosh's reviews disagree with each other.

What WonderBiotics Targets Instead, and What the Evidence Shows

We built WonderBiotics Probiotics for Weight Management around a different problem: an eight-strain gut-microbiome blend (including Bifidobacterium animalis subsp. lactis B420 and HN019) plus a separate metabolic blend of dihydroberberine and a lemon fruit extract standardized to eriocitrin (marketed as Eriomin®), positioned for midsection fat, appetite, and the GI shifts that show up during a weight-loss or GLP-1 routine.¹³ It contains no black cohosh, chasteberry, or vitamin B6/D3, and doesn't claim to touch hot flashes or mood.

The best human evidence behind B420 comes from a 2016 randomized, placebo-controlled trial in 225 overweight and obese adults, and the results vary across the primary, secondary, and post-hoc analyses.¹⁰ The trial's predefined primary endpoint, relative change in DXA-measured body fat at 6 months across all four randomized arms, was not significant (ANCOVA P=0.46, n=199 analyzed).¹⁰ In the predefined per-protocol group (134 people who stuck to the protocol), B420 combined with a fiber supplement did show a significant fat-mass reduction (−4.5%, roughly 1.4 kg, P=0.02); B420 taken alone did not reach significance in that same analysis (−3.0%, P=0.28).¹⁰ A post-hoc factorial analysis, run after unblinding because so few participants ended up in the B420-alone arm, pooled both B420-containing arms against both non-B420 arms and found a larger effect on fat mass (−4.0%, P=0.002) and a significant 2.4 cm (about 0.9 inches) difference in waist-circumference change for the pooled B420-containing arms versus the pooled non-B420 arms (P=0.004).¹⁰ That analysis generated a hypothesis about the combination; it didn't test B420 head-to-head against B420-plus-fiber, and it wasn't part of the trial's original plan. The study was funded by DuPont Nutrition & Health (the company behind B420 at the time; the brand now sits under IFF), and several authors were DuPont employees.¹⁰ A separate secondary analysis of self-reported food diaries found people on B420 alone ate roughly 320 fewer calories per day than their own baseline, versus placebo the group difference was closer to 300 kcal/day; that's a self-reported, non-primary finding, and the trial never measured hunger hormones or appetite directly.¹⁰

The dihydroberberine and eriocitrin ingredients in the metabolic blend have their own separate, smaller evidence bases, and both trials were funded by the ingredient manufacturers. A pilot crossover study of dihydroberberine involved just 5 healthy men; it was funded by NNB Nutrition, and one author served as a paid advisor to that company.¹² The eriocitrin extract (Eriomin®) raised GLP-1 and lowered blood sugar markers in a crossover trial of adults with elevated blood sugar, not a weight-loss or appetite trial; that trial was funded by Ingredients by Nature, Eriomin's manufacturer.¹¹ Both are reasonable additions with a documented mechanism, not confirmation that the combined capsule reproduces either result.

None of these trials tested the finished capsule itself, and none enrolled a specifically menopausal population. That's different from MENO's ashwagandha trial, which did enroll women with menopausal symptoms specifically, albeit at two to four times MENO's dose and without probiotics or the formula's other ingredients. The target differs, too: we built this formula for the weight, appetite, and GI-comfort side of the symptom list, which is why we position it as part of a GLP-1 routine, addressing the gas, bloating, and digestive adjustment that often show up alongside appetite changes or GLP-1 medication use, rather than as a hot-flash or mood remedy.¹³ In the same 2016 trial's safety data, GI complaints were generally mild with no significant difference in adverse-event rates between B420 and placebo groups. That doesn't show a bloating benefit; it just means B420 wasn't linked to more GI side effects than placebo.¹⁰

"Hormone-Free" Isn't the Same Claim as "Works Like Hormone Therapy"

Both MENO and WonderBiotics Probiotics for Weight Management are marketed as hormone-free, and in both cases that simply describes what's not in the bottle: no estrogen, progesterone, or other hormones.^{1, 13} It isn't a claim that either product matches the symptom relief of prescription hormone therapy, and neither company states otherwise.

If hot flashes, night sweats, or mood changes are frequent enough to disrupt your sleep or daily life, that's worth raising with a clinician who can walk you through the full range of options, hormonal and non-hormonal, and your personal risk factors. If you're on a GLP-1 medication or any prescription drug, mention any supplement you're adding, including either product discussed here, so your care team can flag interactions. If you have liver disease or notice unusual fatigue, dark urine, or yellowing of the skin or eyes while taking a black cohosh–containing product, stop and call your doctor; that's the specific caution NIH's fact sheet raises, even though it stops short of confirming cause and effect.⁶

Which One Actually Fits Your Concern?

• Hot flashes, night sweats, mood swings, occasional sleeplessness: MENO's ingredient list is built for this cluster, with the strongest single-ingredient trial data behind ashwagandha KSM-66® (tested at two to four times MENO's actual dose) and conflicting review-level data behind black cohosh.^{1, 6, 8, 14}
• Weight, appetite, or GLP-1-related GI discomfort: this isn't what MENO is for, by O Positiv's own product lineup. WonderBiotics Probiotics for Weight Management is built around this exact list, backed by trial data on its lead strain that includes both a null primary endpoint and significant secondary and post-hoc findings.^{13, 10}
• Bloating specifically, without a weight or hot-flash focus: none of the three O Positiv products or the WonderBiotics weight formula ran bloating as a primary trial endpoint. If digestive comfort is your main complaint, a gut-focused approach is worth comparing separately rather than assuming any of these products was tested for it directly.
• All of the above: nothing here says you have to pick one. A hormone-free symptom formula and a gut-and-appetite-focused probiotic are targeting different systems, and it's reasonable to evaluate them on separate timelines rather than expecting either one to cover the other's job.

Where This Leaves You

O Positiv MENO and WonderBiotics Probiotics for Weight Management aren't really competing for the same purchase. MENO is a hormone-free herbal formula for hot flashes, night sweats, and mood, with mixed evidence across its three lead ingredients. WonderBiotics is a probiotic-and-metabolic-blend formula for weight, appetite, and GLP-1-adjacent GI comfort, backed by human trial data on its lead strain that mixes a null primary endpoint with significant secondary and post-hoc findings. If your search brought you here because of weight, bloating, or appetite specifically, that's the list O Positiv itself routes you away from MENO for, and it's the list WonderBiotics was built around.
