Adaptogen
Maca Root
Maca root shows modest promise for hot flashes and sexual function in small studies of menopausal women, with some trials finding meaningful improvements in both areas. Unlike soy isoflavones, maca doesn't contain plant estrogens but may support the hypothalamus and pituitary gland in their dance of hormonal communication. The evidence is limited to short-term studies, but if you're struggling with decreased libido or frequent hot flashes, an 8-12 week trial of gelatinized maca could be worth considering.

Overall: Mixed evidence
Randomised controlled trials
Several small randomized controlled trials show modest improvements in hot flashes and sexual function, but most included fewer than 50 women and lasted only 6-12 weeks.
Limited observational data exists on maca use in menopausal women outside of clinical trials.
No comprehensive meta-analyses have been conducted specifically on maca for menopause symptoms.
Menopause-specific trials
Most maca research has been conducted specifically in perimenopausal and postmenopausal women, showing modest benefits for vasomotor symptoms and sexual health.
What we do not know
We don't know how maca compares to hormone therapy or other proven treatments in head-to-head trials. Most studies followed women for only 6-12 weeks, so we have no data on safety or effectiveness with long-term use. The optimal dose remains unclear, with studies using different amounts and forms of maca. We lack evidence in women under 45 or over 65, and most trials included fewer than 100 participants. The mechanism of how maca might work remains largely theoretical.
How it is used
Common dose range
1.5-3g daily of gelatinised maca
Notes on dosing
Gelatinised form is easier to digest than raw. Can be added to smoothies. Give it 8-12 weeks.
Get it from food first
Food sources are better absorbed than most supplements and come with co-factors that support the same pathways. If you eat two or three of these consistently, you may not need a supplement at all.
Fresh maca root
30-50 grams
Raw form traditionally used in Peru, but hard to find outside South America
Maca powder
1-3 teaspoons
Can be added to smoothies or oatmeal, has earthy, slightly nutty flavor
Traditional Peruvian diet
Maca has been consumed for centuries in the Andes as both food and medicine, typically cooked or dried
Adaptogen-rich eating
Combining maca with other stress-supporting foods like ashwagandha and rhodiola in smoothies or warm drinks
What depletes Maca Root
High stress levels, excessive caffeine intake, and poor sleep quality may interfere with adaptogenic herbs' effectiveness. Alcohol consumption and high sugar intake can also blunt the stress-buffering effects that maca may provide.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"Maca won't transform your menopause experience, but it might take the edge off hot flashes and low libido with relatively low risk. The studies are small and short-term, but they're consistent enough that a trial period makes sense if these symptoms are disrupting your life. Start with gelatinized maca and give it at least 8 weeks—your body deserves time to respond."
