Open any perimenopause corner of the internet and you’ll find the same four names on repeat: magnesium, lion’s mane, creatine, collagen. Powders for brain fog, gummies for sleep, capsules promising to hand your hormones back to you. The marketing is confident. The evidence, it turns out, is a lot more mixed than the packaging lets on.
The one that mostly holds up
Magnesium is involved in more than 300 processes in your body: muscle relaxation, nerve signaling, blood pressure regulation. In menopausal women specifically, it’s shown real promise for sleep and a modest dent in anxiety, and there’s some support for bone density too. Where it falls short: hot flashes and cognitive symptoms. If your feed sold you on magnesium fixing brain fog, that part isn’t backed by the research yet.
The one riding animal studies in your cart
Lion’s mane has genuine buzz behind it. Animal studies suggest it may stimulate new brain cell growth and support brain structures tied to memory, and one rat study found it reduced depressive type behavior in menopausal rats. Promising, except rats aren’t people. The small human trials that exist show mixed results, and notably, none of them were actually done in menopausal women. It’s generally well tolerated if you want to try it, but “well tolerated” and “proven to work for you” are two different sentences.
The one nobody expected to work
Creatine has decades of research behind it, almost entirely in men, which made its sudden popularity in perimenopause circles feel more like a trend than a treatment. Except the newer data is surprisingly solid: a 14 week study found creatine meaningfully improved lower body strength and sleep quality in perimenopausal women. Of the four, it’s the one with results in postmenopausal women that are still catching up.
The one that’s better than its reputation
Collagen gets dismissed as an influencer supplement, but a major review found the science is more credible than the wellness industry hype around it would suggest. It shows modest support for bone density and joint comfort. The catch is product quality varies enormously between brands, which makes it hard to know if a given tub does what the research subject’s version did.
The actual takeaway
Of the four, magnesium and creatine currently have the most going for them, and even there, the researchers are clear more work is needed. None of this means skipping the supplement aisle entirely. It means treating “trending” and “evidence backed” as two separate categories, and remembering that strength training, sleep, nutrition, and cutting back on alcohol are still doing more of the real work than anything in a jar.
