Can green tea really boost testosterone in older men?
A new 2025 study suggests it might. Men who drank green tea daily for 20+ years had significantly higher testosterone levels than those who didn’t.
Specifically:
Green tea drinkers: 574.66 ng/dL (total testosterone)
Non-drinkers: 495.89 ng/dL
That’s a notable difference — and since testosterone plays a key role in energy, mood, muscle tone, and brain function, this could be one way green tea supports healthy ageing in men.
What else did the study look at?
The study included 280 men aged 50+ and measured hormone levels, inflammation, sleep, body weight, mood, and brain structure. Green tea drinkers also showed:
Less body-wide inflammation
Lower BMI (leaner weight)
Fewer signs of depression
Better brain structure in areas linked to memory and focus
These benefits all connect back to testosterone and metabolic health.
What’s the link between testosterone, inflammation, and ageing?
Low testosterone in men is often linked with:
Fatigue
Brain fog
Mood swings or low mood
Loss of muscle or increase in belly fat
The study showed that green tea drinkers had lower inflammation — and that may be one way testosterone levels were better maintained. Less inflammation means your body can manage hormones more effectively and avoid the hormonal decline often seen with ageing.
What’s in green tea that helps?
Green tea is packed with powerful antioxidants, especially EGCG and catechins. These natural compounds are known for:
Fighting inflammation
Supporting blood sugar balance
Helping cells function more efficiently
That means a simple cup of green tea may help protect your hormones and your brain as you age — without needing medication.
Could it help my brain too?
Possibly. Brain scans in the study showed more gray matter in key brain regions for men who drank green tea — especially in areas involved in memory and mental clarity. Combined with higher testosterone and lower inflammation, this points to a strong potential benefit for brain ageing.
What are the limitations?
It’s important to know:
This was an observational study, so it can’t prove green tea causes these benefits.
The testosterone measured was total, not the “free” form your body actively uses.
Tea habits were self-reported, and other lifestyle factors weren’t fully controlled.
Still, the link is strong enough to suggest that adding green tea to your routine could support men’s health naturally — especially if you’re over 40.
