The best ways to increase testosterone naturally are to lose excess body fat, lift weights, sleep 7 or more hours, limit alcohol and manage stress. These habits support healthy levels at any age. They won’t fix a medical problem, though. If you have symptoms like low sex drive, fatigue and loss of muscle, get a blood test before trying supplements or therapy.
Key takeaways
- – Testosterone drops slowly with age, about 1% a year after 30 or 40.
- Extra body fat, poor sleep, heavy drinking and some medicines are common causes of low testosterone.
- Strength training, sleep and weight loss are the most reliable natural steps.
- Most “testosterone booster” supplements have weak evidence.
- Low testosterone is diagnosed with two morning blood tests, not symptoms alone.
What Does Testosterone Do?
Testosterone is the main male sex hormone. It’s made mostly in the testicles. It drives male traits in puberty, like a deeper voice and body hair, and keeps working throughout adult life. It helps with:
- Sex drive and erections
- Sperm production
- Muscle mass and strength
- Bone strength
- Energy and mood
- Fat distribution
Some testosterone is also turned into estradiol, a form of estrogen that men need for strong bones. And some is turned into DHT, a hormone linked to hair loss. Here’s how testosterone turns into DHT.
How Does Testosterone Change With Age?
According to Mayo Clinic, testosterone falls gradually, about 1% a year after age 30 or 40. This slow drop doesn’t always cause symptoms.
Low testosterone that causes symptoms is called hypogonadism. Cleveland Clinic says doctors usually consider levels below 300 ng/dL low in adults. It notes that most men with symptoms have low levels linked to obesity or type 2 diabetes.
Signs of Low Testosterone
- Low sex drive
- Fewer morning or spontaneous erections, or trouble keeping an erection
- Tiredness and low energy
- Depressed mood or trouble concentrating
- Loss of muscle strength and more body fat
- Breast tissue growth
- Hot flashes or shrinking testicles (less common, but more specific)
These symptoms overlap with many other problems, like poor sleep, depression, thyroid issues or sleep apnea. If you’re always worn out, read about the reasons you feel tired all the time, then talk to a doctor.
How to Increase Testosterone Naturally: 7 Steps
1. Lose excess body fat
This is one of the most powerful steps. Obesity is a leading cause of low testosterone in men. Even modest weight loss can help. Focus on a small calorie deficit, plenty of protein and daily movement rather than crash diets.
2. Lift weights
Mayo Clinic notes that doctors often suggest losing weight and building muscle through resistance exercise for men without an underlying medical condition. Train all major muscle groups 2 to 3 days a week with exercises like squats, presses, rows and deadlifts. New to lifting? Start with a beginner strength routine.
3. Sleep 7 or more hours
Sleep matters more than most men think. In a University of Chicago study, healthy young men who slept under 5 hours a night for about a week had a 10% to 15% drop in daytime testosterone. Here’s more on how sleep loss affects your hormones.
Untreated sleep apnea can also lower testosterone. If you snore loudly or wake up gasping, see a doctor.
4. Limit alcohol
Heavy drinking can harm the testicles and lower testosterone. Keep drinking moderate, or cut back if you drink most days.
5. Manage stress
Long-term stress can disrupt your hormones and sleep. Regular exercise, time outdoors and simple breathing exercises help.
6. Eat a balanced diet
There’s no single “testosterone food.” Focus on:
- Protein at each meal: meat, fish, eggs, dairy, beans or tofu
- Healthy fats: olive oil, nuts, seeds and fatty fish
- Zinc-rich foods: beef, shellfish, beans and pumpkin seeds
- Vitamin D sources: fatty fish, eggs and fortified foods
If you think you’re low in zinc or vitamin D, ask your doctor for a blood test before taking supplements.
7. Review your medicines and substances
Opioids, anabolic steroids and some other drugs can lower testosterone. Ask your doctor whether anything you take could be a factor. Don’t stop a prescribed medicine on your own.
What About Testosterone Booster Supplements?
You’ll see ashwagandha, fenugreek, D-aspartic acid and many blends sold as “T boosters.” The evidence for most is limited or mixed, and supplements aren’t regulated like medicines in the US. Some can interact with medications.
If you want to try one, talk to your doctor first and pick a product tested by an independent lab. Don’t expect it to fix true low testosterone.
How to Check Your Testosterone
A simple blood test measures it. Cleveland Clinic notes that doctors usually check two separate morning samples, because levels are highest in the morning. Illness can lower levels for a while.
Your doctor may also check:
- Free testosterone: the part not bound to proteins in your blood
- LH and prolactin: to see if the pituitary gland is involved
What You Should Know About Testosterone Therapy (TRT)
Testosterone replacement therapy can help men with diagnosed hypogonadism. It isn’t recommended just for normal aging. Mayo Clinic says treating normal aging with testosterone therapy isn’t advisable.
Possible risks, according to Mayo Clinic:
- Lower sperm production and smaller testicles, so it’s usually not used by men who want children
- Too many red blood cells, which raises the risk of blood clots
- Worse sleep apnea
- Acne
- Breast enlargement
- Prostate growth
Heart safety: The large TRAVERSE trial, reported in 2023, followed about 5,200 men aged 45 to 80 with low testosterone and heart risk. It found testosterone therapy didn’t raise the rate of heart attack, stroke or heart-related death compared with placebo, according to an HCPLive report on the trial. It did see more abnormal heart rhythms and kidney injury.
TRT should only be prescribed and monitored by a doctor. Never use testosterone or steroids bought online.
Testosterone Habits by Age
| Age | Focus |
|---|---|
| 20s–30s | Build lifelong habits: lift weights, sleep well, avoid steroids and heavy drinking |
| 30s–40s | Keep body fat in check, manage stress, protect sleep |
| 40s–50s | Keep lifting, watch your waistline, get checked if symptoms appear |
| 50+ | Stay active and strong, review medicines with your doctor, test if you have symptoms |
When to See a Doctor
See a doctor if you have ongoing symptoms like low sex drive, erection problems, fatigue, depressed mood or loss of muscle. Also see one if you have type 2 diabetes, obesity, sleep apnea or take opioids, since these are linked to low testosterone.
Frequently Asked Questions

Do testosterone booster supplements work?
Most have limited or mixed evidence. Talk to a doctor before taking one, especially if you take other medicines.
What is a normal testosterone level for men?
Cleveland Clinic says levels below 300 ng/dL are usually considered low in adults. Your doctor will look at your symptoms and repeat tests before making a diagnosis.
Next step: Pick one habit from this list to start this week, like a set bedtime or 2 strength workouts. If you have symptoms of low testosterone, book a morning blood test with your doctor.
