As men age, testosterone levels naturally decline. Starting in your 50s, testosterone may decrease by 1% to 2% each year, which can impact muscle and bone health, sex drive, blood cell production, and fertility. While low testosterone should be evaluated by a healthcare professional, certain foods and lifestyle choices may help support hormone levels naturally.
Oysters and Other Zinc-Rich Shellfish
Zinc plays a key role in testosterone production, and oysters contain more zinc per serving than any other food. Studies suggest that amino acids in shellfish, including oysters, may support Leydig cell function, the primary testosterone-producing cells in the body.
Other zinc-rich shellfish include:
- Shrimp
- Crab
- Lobster
- Mussels
- Clams
Fatty Fish
Fatty fish like salmon, mackerel, and tuna provide zinc and vitamin D, both essential for hormone regulation. Research shows that older men who consume higher amounts of fatty fish may have higher testosterone levels compared to those with lower intake. Lean fish can also help, but the effect is smaller.
Leafy Greens and Cruciferous Vegetables
Magnesium-rich leafy greens, such as spinach, kale, and collard greens, may support testosterone production. Cruciferous vegetables, including broccoli, cauliflower, cabbage, and Brussels sprouts, contain indole-3-carbinol (I3C), which helps balance estrogen and may indirectly support testosterone.
Avocados
Avocados are high in magnesium and boron, both linked to testosterone production. Research suggests boron supplementation may increase testosterone levels and help support sexual health. Avocados are also rich in healthy fats, which are important for hormone synthesis.
Cocoa
Cocoa contains quercetin, a flavonoid with antioxidant properties. Small studies indicate it may help increase testosterone levels, although most research is limited to short-term trials.
Herbs
Some herbs may support testosterone production, though research is still emerging. Fenugreek has been shown to raise testosterone levels by 22% over 12 weeks in one study. Ashwagandha may increase testosterone by 18% in older men over eight weeks.
Lifestyle Changes to Support Testosterone
Diet alone may not be enough. Incorporating these lifestyle habits can help maintain healthy testosterone levels:
- Exercise: Resistance training and aerobic activity support hormone production and healthy weight.
- Sleep: Most testosterone is produced during REM sleep. Adults should aim for 7–9 hours per night.
- Stress management: Reducing stress and avoiding environmental toxins like BPA and phthalates can protect hormone balance.
- Avoid tobacco, limit alcohol, and minimize opioids: These substances may negatively impact testosterone levels.
Recognizing Low Testosterone Symptoms
Low testosterone can cause fatigue, reduced muscle mass, low sex drive, irritability, depression, and erectile dysfunction. A healthcare professional can confirm low testosterone through blood tests and help determine appropriate treatment options.
