Quick Answer
There isn’t currently a body of research directly comparing Lion’s Mane’s effects between men and women. Most human trials, particularly those looking at cognition and mood, have included mixed-sex groups without analysing results by sex as a variable. The clearest sex-specific finding comes from a small study in menopausal women looking at mood, not a broader comparison. Claims about sex-specific effects on hormones or libido circulating online are largely speculative rather than evidence-based, so it’s worth treating that framing with some caution.
Why “Men vs Women” Is a Harder Question Than It Sounds
It’s a genuinely reasonable question to ask, since plenty of supplements do show different effects or dosing needs across sexes. But for Lion’s Mane specifically, the honest answer is that the research simply hasn’t been designed to test that comparison directly in most cases.
The human trials that exist on cognitive function and mood have generally recruited mixed-sex cohorts and reported results for the group as a whole, without breaking findings down by sex. That’s a common limitation in nutrition and supplement research generally, not something unique to Lion’s Mane, but it does mean confident claims about how the mushroom affects men differently from women aren’t something the current evidence actually supports.
What the Research Does Show
General cognitive and mood effects, not sex-differentiated ones. The studies with the clearest signal, including trials on cognitive function in healthy adults, have looked at mixed groups. Where mood or cognitive improvements have been reported, they haven’t been attributed to sex as a meaningful factor.
One specific study in menopausal women. A small trial examined the effects of Hericium erinaceus supplementation on menopausal women, finding a reduction in self-reported feelings of irritation and anxiety after around a month of daily intake. This is a genuine, specific data point, but it’s a study of a particular life stage and symptom profile in women, not a broad “benefits for women” finding, and it doesn’t tell us anything about comparative effects in men.
Animal research on hormones and libido remains preliminary. Some animal studies have looked at Lion’s Mane’s effects on reproductive markers such as sperm quality and erectile function in male animal models, and there’s ongoing interest in whether it might interact with hormone pathways more broadly. This research is genuinely interesting from a scientific perspective, but it’s a considerable leap from animal studies to confident claims about human libido or testosterone effects, and that leap is exactly where a lot of online content oversteps what the evidence actually supports.
Why This Matters: it matters because supplement marketing sometimes fills evidence gaps with plausible-sounding mechanism stories, such as claims about testosterone or libido effects extrapolated from limited animal data or theoretical hormone pathways. That’s a different thing from a human trial actually demonstrating the effect. Being clear about that distinction protects you from expecting something the research doesn’t currently back up, whichever sex you are.
Most functional mushroom research to date has prioritised recruiting any available adult participants over analysing outcomes by sex, which is a broader pattern in nutritional supplement research rather than something specific to Lion’s Mane.
So Is There Any Reason to Expect Different Effects?
Biologically, it’s not an unreasonable question. Hormone profiles, body composition, and metabolism do differ between men and women in ways that affect how some substances are processed. But reasonable biological plausibility isn’t the same as demonstrated effect, and for Lion’s Mane specifically, no trial has yet been designed to test whether men and women respond differently to standardised supplementation.
Until that research exists, the more honest position is that Lion’s Mane’s studied benefits, mainly around cognition and mood, appear to apply broadly rather than being specific to one sex, with the exception of the menopausal mood study noted above, which speaks to a particular life stage and symptom set rather than a general sex-based difference.
How to Evaluate Sex-Specific Supplement Marketing Generally
This isn’t a problem unique to Lion’s Mane. Sex-targeted marketing is common across the wider supplement industry, and it’s worth having a general approach to evaluating it rather than taking product names at face value.
A useful habit is asking whether a specific claim traces back to a human trial that actually compared outcomes by sex, or whether it’s built on a plausible-sounding mechanism, an animal study, or simply an assumption based on general biology. The former is meaningfully stronger evidence than the latter, and for Lion’s Mane specifically, most sex-differentiated marketing currently falls into the weaker category.
That doesn’t mean sex differences in supplement response are impossible or unimportant to study. It means that for this particular mushroom, at this point in the research, confident claims in either direction outpace what’s actually been demonstrated.
What This Means for Choosing a Product
Because there’s no solid evidence for sex-specific dosing or formulation needs, there’s little reason to seek out products marketed specifically “for men” or “for women” over a standard, well-sourced Lion’s Mane supplement. The factors that matter more are the same ones covered in our Lion’s Mane buying guide: extraction source, whether it’s fruiting body or mycelium-based, and clear labelling.
Pro Tip: be sceptical of any product specifically marketed around dramatic sex-specific claims, particularly around hormones or libido. That marketing angle tends to outpace the actual research base considerably.
Pro Tip: if you’re a woman going through menopause specifically interested in mood-related effects, the existing small study is a genuinely relevant data point to be aware of, more so than general “for women” marketing framing.
Common Mistakes
Assuming marketing claims reflect a real research base. Sex-specific hormone or libido claims are common in supplement marketing generally, but for Lion’s Mane, they currently outpace what human research actually demonstrates.
Treating the menopausal mood study as evidence of broad, general benefits for women. It’s a specific finding in a specific population and symptom set, not a general “Lion’s Mane is better for women” conclusion.
Assuming animal research on hormones translates directly to humans. Preliminary animal findings on reproductive markers are a reasonable basis for further human research, not a confirmed human effect.
Buying a “for men” or “for women” branded product expecting different formulation benefits. Without dedicated comparative research, there’s currently no solid basis for expecting a meaningfully different effect from sex-targeted marketing alone.
FAQ
Does Lion’s Mane affect testosterone levels? Some animal and preliminary research has explored this question, but there isn’t robust human trial evidence confirming a meaningful effect on testosterone levels one way or the other.
Is Lion’s Mane better for men or women? Neither, based on current evidence. Most research applies to mixed groups without sex-specific analysis, so there’s no solid basis for claiming it works better for one sex than the other.
What is the menopausal women’s study about Lion’s Mane? A small study found that women in menopause who consumed Hericium erinaceus daily for around a month reported reduced feelings of irritation and anxiety. It’s a specific, genuine finding, but a narrow one rather than broad evidence for all women.
Should men take a different dose of Lion’s Mane than women? There’s no dedicated research establishing different dosing needs by sex. Following the product-specific guidance on whatever supplement you’re using, and speaking to a healthcare professional if unsure, remains the sensible approach regardless.
Can Lion’s Mane help with libido? This is an area with limited, largely preliminary evidence, mostly from animal studies. It’s not something the current human research base confidently supports either way.

About This Guide
SporeBuddies tracks published research on functional mushrooms on an ongoing basis, and this guide reflects that research tracking applied honestly to a commonly asked question. Where the evidence is limited or preliminary, we’ve said so directly rather than filling the gap with speculative claims.
In Summary
Lion’s Mane doesn’t currently have a dedicated body of research comparing its effects between men and women. Most human trials use mixed-sex groups, the clearest sex-specific finding is a narrow study in menopausal women, and claims about testosterone or libido effects remain largely speculative rather than demonstrated. The most reliable approach is to focus on the general, well-supported benefits around cognition and mood, and treat sex-specific marketing claims with a healthy amount of scepticism.
