Supplement
Sulforaphane
Sulforaphane shows strong evidence for supporting your body's natural detoxification systems and reducing inflammation, with early research suggesting it may help your body process estrogen more efficiently. Most studies have been done in laboratory settings or on younger adults, leaving significant gaps in our knowledge about how it works specifically during perimenopause. Fresh broccoli sprouts offer the most potent and absorbable form you can easily grow at home or find in many grocery stores.

Overall: Mixed evidence
Randomised controlled trials
Small trials show sulforaphane reduces inflammatory markers and supports detoxification, but most studies are short-term and not in menopausal women.
Population studies link cruciferous vegetable intake to better hormone metabolism and reduced disease risk.
Systematic reviews confirm consistent anti-inflammatory and detoxification benefits across multiple studies.
Menopause-specific trials
No clinical trials have specifically studied sulforaphane for menopause symptoms or hormone changes.
What we do not know
No randomized trials have specifically studied sulforaphane in perimenopausal or menopausal women. The optimal dose for hormone-related benefits has not been established through clinical trials. Most research on estrogen metabolism has been done in test tubes or animal models, not human studies. We don't know if sulforaphane interacts with hormone replacement therapy or other menopause treatments. Long-term safety data for daily supplementation is limited.
How it is used
Common dose range
30-60mg daily or 50-100g fresh broccoli sprouts
Notes on dosing
Fresh broccoli sprouts are the most bioavailable source. Look for products with both glucoraphanin and myrosinase.
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.
Broccoli sprouts
50-100 grams
Highest concentration, 10-100x more than mature broccoli
Raw broccoli
2-3 cups
Must be chopped and wait 40 minutes for enzyme activation
Brussels sprouts
1 cup
Good source when lightly steamed
Cauliflower
1.5 cups
Raw or lightly cooked provides moderate amounts
Watercress
2 cups
Peppery green with good bioavailability
Cruciferous-rich eating
Regular intake of broccoli family vegetables supports consistent sulforaphane levels
Raw or lightly cooked preparation
Preserves the enzyme needed to convert precursors to active sulforaphane
What depletes Sulforaphane
Cooking at high temperatures destroys the enzyme needed to form sulforaphane. Frozen cruciferous vegetables have reduced activity. Gut microbiome imbalances may impair the conversion of precursor compounds to active sulforaphane.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"The detoxification and anti-inflammatory effects are well-established, even if the hormone-specific benefits need more research. Growing your own broccoli sprouts gives you the freshest, most potent source while you wait for science to catch up. Your body's ability to clear toxins and manage inflammation matters deeply during this transition, and this is one tool with solid science behind those core benefits."
