How to Improve Testosterone: 13 Proven Steps That Help

You feel tired, your sex drive is lower, workouts feel harder, and you start wondering whether testosterone is the problem.

Maybe it is. Maybe it is not.

Quick answer: If you want to know how to improve testosterone, start by finding out whether it is actually low. Sleep loss, obesity, severe dieting, illness, some medicines, alcohol, and hormone disorders can lower testosterone. Weight loss when needed, resistance exercise, adequate sleep, balanced nutrition, treatment of underlying health problems, and correction of true nutrient deficiencies can help. Testosterone replacement therapy belongs after proper diagnosis, not before it.

No food, supplement, workout, or herb reliably pushes normal testosterone far above your body's healthy range.

This article is for general information and education. It does not replace medical advice, diagnosis, or treatment.

First, How Do You Know if Testosterone Is Actually Low?

The blood test is simple. Interpreting it properly is less simple.

Testosterone changes throughout the day. Illness, poor nutrition, medicines, sleep, and other factors can also alter the result.

Current Endocrine Society and European Association of Urology guidance recommends confirming suspected male hypogonadism with symptoms plus low morning testosterone measured on more than one occasion.

The 2026 Endocrine Society statement specifically recommends at least two early morning, fasting testosterone tests.

If testosterone is low, the next question is why.

A clinician may consider tests such as:

• Total testosterone
• Free testosterone when appropriate
• Luteinizing hormone
• Follicle stimulating hormone
• Prolactin
• Other tests based on your history

This helps separate a problem in the testicles from one involving signals from the pituitary or hypothalamus.

Which Low Testosterone Symptoms Are Most Useful?

Some symptoms are much more specific than others.

Symptoms do not diagnose the condition on their own.

13 Proven Steps That Support Healthy Testosterone

1. Test Properly Before Trying to “Boost” Anything

This is first because it prevents the most common mistake.

If your testosterone is normal, pushing it higher with supplements or prescription hormones is not evidence based treatment.

The 2026 European guideline specifically recommends against testosterone therapy in men with normal testosterone.

If symptoms are present, get tested correctly and investigate the cause.

2. Lose Excess Weight if Obesity Is Part of the Problem

This is one of the strongest lifestyle interventions for men with obesity related low testosterone.

Obesity can suppress the hormone system that controls testosterone production.

The 2026 European guideline recommends weight loss and lifestyle change as the first approach for men with obesity associated functional hypogonadism.

The increase in testosterone from lifestyle change is usually modest, but it can be meaningful when excess weight is a major part of the problem.

Use a sustainable approach rather than extreme dieting.

For a practical weight management guide, see Weight Loss After 40.

3. Use Resistance Training for Strength and Metabolic Health

Resistance training is a sensible part of a testosterone friendly lifestyle.

Exercises can include:

• Squats
• Rows
• Presses
• Deadlift variations
• Pulling movements
• Leg presses
• Bodyweight exercises

Resistance exercise can cause short term changes in testosterone after training, but those temporary spikes should not be confused with curing clinical hypogonadism.

The bigger long term value comes from maintaining muscle, improving fitness, supporting glucose control, and helping with body composition.

You do not need to build your entire program around the exercise that produces the largest temporary hormone spike.

See Strength Training After 40 for a practical training framework.

4. Add Regular Aerobic Exercise Without Training Yourself Into the Ground

Cardio supports heart health, fitness, insulin sensitivity, and weight management.

Walking, cycling, swimming, jogging, or other activities can all fit.

HIIT is optional.

The old advice that everyone needs several HIIT sessions each week specifically to raise testosterone is too strong.

Hard training can cause a short term hormone response, but excessive training combined with poor recovery and inadequate food can work against normal hormone function.

Train consistently. Recover consistently too.

5. Get Enough Sleep

Sleep and testosterone are closely linked.

Testosterone follows a daily rhythm, and sleep disruption can interfere with normal hormone patterns.

For most adults, a realistic target is about seven to nine hours when possible.

Focus on:

• A regular sleep schedule
• A dark, quiet room
• Limiting late caffeine
• Reducing alcohol near bedtime
• Giving yourself enough time in bed

You do not need magnesium simply because you want deeper sleep.

Read Sleep Hygiene and Sleep Deprivation for the wider sleep picture.

6. Check for Sleep Apnea if the Clues Fit

This deserves its own section because people often treat fatigue as a testosterone problem while missing a sleep disorder.

Possible sleep apnea clues include:

• Loud frequent snoring
• Breathing pauses during sleep
• Gasping at night
• Daytime sleepiness
• Morning headaches
• Difficulty concentrating
• Low libido

If those symptoms fit, ask about sleep assessment.

A testosterone supplement will not fix blocked breathing during sleep.

7. Eat Enough Food to Support Your Body

Severe calorie restriction and poor nutrition can temporarily lower testosterone.

This matters for men who combine hard training with very low calorie diets.

A sustainable eating plan should provide enough:

• Energy
• Protein
• Essential fats
• Vitamins
• Minerals

Crash dieting is not a hormone optimization strategy.

8. Stop Looking for One Testosterone Superfood

There is no single food that reliably raises testosterone in everyone.

Oysters contain zinc. Fish can provide vitamin D. Nuts, vegetables, eggs, dairy foods, beans, meat, and other foods supply useful nutrients.

That does not turn them into testosterone drugs.

The stronger approach is a balanced diet that supports healthy body weight and covers your nutrient needs.

See Testosterone Boosting Foods for a food focused guide, and keep the claims in context.

9. Correct Real Nutrient Deficiencies Instead of Megadosing

Zinc and vitamin D matter to normal health.

That does not mean high doses will increase testosterone when your levels are already adequate.

The old recommendation to automatically take 30 to 45 mg of zinc each day is not a safe general rule.

The NIH adult upper intake level for zinc is 40 mg per day from food and supplements for people not receiving medically supervised treatment. Excess zinc over time can interfere with copper absorption.

Likewise, the NIH adult upper limit for vitamin D is 4,000 IU per day unless a healthcare professional uses a different dose to treat a confirmed deficiency.

Do not use these upper limits as supplement targets.

If you suspect deficiency, testing or professional advice is more useful than guessing.

For more detail, see Vitamin D Deficiency and Zinc and Magnesium Benefits.

10. Limit Heavy Alcohol Use and Avoid Tobacco

High alcohol intake is associated with poorer reproductive health and can work against healthy testosterone function.

Smoking also damages cardiovascular and reproductive health even though its relationship with testosterone level itself is not simple.

If you drink, avoid using alcohol as a sleep aid or recovery tool.

If you smoke, quitting is valuable for reasons much bigger than one hormone number.

11. Review Medicines That Can Lower Testosterone

Some medicines can suppress testosterone production.

Examples include long term opioid pain medicines and some corticosteroid treatments.

Other medicines can cause erectile problems, fatigue, or sexual symptoms that may be mistaken for low testosterone.

Do not stop prescribed medicine on your own.

Ask:

• Could this medicine affect testosterone?
• Could it explain my symptoms another way?
• Is there a safer alternative?

12. Stop Anabolic Steroids and “Testosterone Boosters” From Running the Show

Anabolic steroid use can shut down the body's normal testosterone signaling system.

Exogenous testosterone also suppresses the pituitary hormones needed for sperm production.

Over the counter testosterone boosters are a different problem.

Many contain herbs or proprietary blends with limited evidence. NIH dietary supplement guidance notes that popular ingredients such as Tribulus terrestris have not shown convincing benefits for testosterone, strength, or athletic performance.

Do not assume “natural” means effective or safe.

13. Use Testosterone Replacement Therapy Only When the Diagnosis Fits

Testosterone replacement therapy, or TRT, can help men with properly diagnosed hypogonadism.

It is not a general anti aging, bodybuilding, energy, or masculinity treatment.

Potential benefits in appropriately selected men can include improvement in:

• Low libido
• Some sexual symptoms
• Lean body mass
• Anemia in selected patients
• Bone mineral density

Do not promise benefits that the evidence does not support.

The 2026 European guideline advises against using testosterone simply to improve cognition, vitality, or physical strength in aging men who do not have the appropriate diagnosis.

What Causes Low Testosterone?

Low testosterone is not one disease.

Possible causes include:

• Testicular injury
• Genetic conditions
• Pituitary disorders
• High prolactin
• Chemotherapy or radiation
• Obesity
• Type 2 diabetes
• Sleep disorders
• Severe illness
• Kidney or liver disease
• Opioid medicines
• Corticosteroids
• Anabolic steroid use
• Severe undernutrition

The cause determines the treatment.

Does Testosterone Just Fall Because You Get Older?

Testosterone does tend to decrease with age, but age by itself does not prove hypogonadism.

The Endocrine Society's 2026 statement specifically warns that labels such as “age related” or “late onset” hypogonadism can blur the line between disease and normal aging.

An older man still needs compatible symptoms and consistently low testosterone to receive the diagnosis.

What About Intermittent Fasting?

Intermittent fasting can be a useful eating schedule for some people.

It is not a proven testosterone treatment.

If fasting helps a man with obesity lose excess weight while still meeting nutrition needs, testosterone may improve because the underlying obesity improves.

That is different from saying a 16 hour fast directly boosts testosterone.

Very restrictive fasting or inadequate calorie intake can have the opposite effect.

Does HIIT Raise Testosterone?

Hard exercise can cause temporary hormone changes.

That does not mean several HIIT sessions each week will permanently correct low testosterone.

Use HIIT because it fits your fitness goals, health, and training plan.

Do not use it as a replacement for medical evaluation of hypogonadism.

See HIIT Workouts for Men if you want to use this training style safely.

Does Stress Lower Testosterone?

Chronic stress can affect sleep, exercise, eating, alcohol use, weight, sexual function, and overall wellbeing.

Those effects matter.

But telling someone that a 20 minute meditation session will directly raise testosterone is too simplistic.

Manage stress because it improves health and recovery, not because you expect a guaranteed hormone spike.

The Mental Health and Wellness Hub contains practical guides for stress, sleep, and emotional wellbeing.

What About Environmental Toxins?

Certain environmental chemicals can affect reproductive health, and reducing unnecessary exposure is reasonable.

That does not mean you need to:

• Eat only organic food
• Throw away every plastic container
• Buy bottled water
• Purchase an air purifier to raise testosterone
• Follow a detox program

Those claims move far beyond the evidence.

Focus first on the large, measurable factors: weight, sleep, health conditions, medicines, alcohol, nutrition, physical activity, and correct diagnosis.

Can Vitamin D Raise Testosterone?

Vitamin D deficiency should be corrected for normal health.

But vitamin D should not be sold as a guaranteed testosterone booster.

If your vitamin D level is adequate, taking more does not guarantee higher testosterone.

High doses can also cause harm.

The NIH notes that excessive vitamin D supplementation can cause high blood calcium, kidney stones, kidney injury, abnormal heart rhythm, and other problems.

Can Zinc Raise Testosterone?

Severe zinc deficiency can interfere with normal reproductive function.

Correcting a deficiency makes sense.

Taking high dose zinc when you are not deficient is different.

Long term excess zinc can cause copper deficiency and other problems.

Food first is a reasonable approach for most people:

• Shellfish
• Meat
• Poultry
• Beans
• Nuts
• Seeds
• Fortified foods

Does Magnesium Increase Testosterone?

Magnesium is an essential mineral.

That does not make magnesium tablets a general testosterone treatment.

Correct an actual deficiency when present. Do not take large supplemental doses simply because a hormone article says magnesium “boosts free testosterone.”

TRT and Fertility: The Warning Men Should See Before Treatment

This is one of the most important sections on the page.

Taking testosterone from outside the body reduces signals from the brain and pituitary that tell the testes to make testosterone and sperm.

Sperm production can fall sharply or stop.

The 2026 European guideline strongly recommends against testosterone therapy in men who want to father children.

AUA and ASRM fertility guidance gives the same warning.

If you want children now or later, tell the endocrinologist or urologist before treatment.

Other specialist treatments may sometimes be used when low testosterone and fertility need to be managed together.

Does TRT Increase Heart Attack Risk?

The answer is more nuanced than older warnings suggested.

FDA reviewed the large TRAVERSE cardiovascular safety trial and removed older boxed warning language about increased major cardiovascular events from testosterone product labeling in 2025.

That did not make TRT risk free.

FDA also added or retained information about blood pressure, while the Endocrine Society noted in its 2026 statement that questions remain about long term safety and certain outcomes.

The right conclusion is not “TRT is dangerous” or “TRT is completely safe.”

It is a prescription treatment that requires the right diagnosis, risk discussion, and monitoring.

What Should Be Checked Before and During TRT?

The exact plan depends on age, health history, and the form of testosterone used.

Monitoring can include:

• Testosterone level
• Hematocrit
• Blood pressure
• Symptoms and side effects
• Prostate assessment when appropriate
• Fertility goals

The 2026 EAU guideline recommends testosterone and hematocrit checks at three, six, and twelve months after treatment begins, then annually in appropriate patients.

A high hematocrit may require treatment adjustment or interruption.

Who Should Not Start TRT Without Specialist Review?

Testosterone treatment needs extra caution or may be inappropriate when certain conditions are present.

These include situations such as:

• Current fertility plans
• Very high hematocrit
• Active prostate or breast cancer
• Important prostate concerns that have not been evaluated
• Serious uncontrolled medical conditions

Your own medical history matters more than an online eligibility quiz.

Can TRT Improve Erectile Dysfunction?

Sometimes, if true testosterone deficiency contributes to the erectile problem.

But many cases of erectile dysfunction are related to:

• Blood vessel disease
• Diabetes
• High blood pressure
• Nerve problems
• Medicines
• Stress or depression
• Smoking

A testosterone prescription is not the automatic first treatment for every man with erectile dysfunction.

Does TRT Improve Muscle and Strength?

Testosterone treatment in hypogonadal men can increase lean body mass.

That is not the same as recommending TRT to healthy men for gym performance.

The 2026 EAU guideline specifically advises against using testosterone to improve physical strength in aging men without the appropriate indication.

Strength training remains the better starting point for a man with normal testosterone.

How Long Does It Take to Improve Testosterone Naturally?

There is no universal six week deadline.

The timeline depends on what is causing the low level.

Weight loss takes time. Sleep recovery may change hormone patterns sooner. Treating a vitamin deficiency follows another timeline. Pituitary or testicular disease may require specific medical therapy.

Do not schedule random repeat tests simply because an internet article tells you to retest in six weeks.

Your clinician can choose the right timing.

Common Testosterone Mistakes to Avoid

Testing Once in the Afternoon

A single poorly timed result can mislead you.

Treating Fatigue as Proof of Low Testosterone

Fatigue has dozens of causes.

Taking High Dose Zinc

More zinc is not more testosterone, and excessive intake can cause copper deficiency.

Taking Vitamin D Without Considering the Dose

Deficiency treatment and casual high dose supplementation are not the same thing.

Using Intermittent Fasting as Hormone Therapy

Fasting is an eating pattern, not a proven testosterone medicine.

Chasing Short Term Workout Hormone Spikes

A temporary laboratory change after exercise is not the same as raising your usual testosterone level.

Starting TRT Before Discussing Fertility

Exogenous testosterone can sharply suppress sperm production.

Buying “Natural Testosterone Boosters”

Many lack convincing evidence and may contain several ingredients at uncertain doses.

Using Testosterone With Normal Levels

Current European guidance advises against testosterone treatment in men whose testosterone is normal.

Questions to Ask Your Doctor

1. Do my symptoms actually suggest testosterone deficiency?
2. Should I have two early morning testosterone tests?
3. Do I need free testosterone measured?
4. What is causing my low level?
5. Could obesity, sleep apnea, illness, or a medicine be contributing?
6. Should LH, FSH, or prolactin be checked?
7. Could weight loss improve my testosterone?
8. Do I have a nutrient deficiency?
9. Could any supplement I take be harmful?
10. How would TRT affect my fertility?
11. What benefits should I realistically expect from TRT?
12. What monitoring would I need?

Conclusion

If you want to know how to improve testosterone, do not start with a supplement shelf.

Start with the cause.

For men with obesity related low testosterone, sustainable weight loss can help. Regular resistance training, adequate sleep, appropriate aerobic activity, enough food, and correction of true nutrient deficiencies support normal hormone function. Medicines, sleep disorders, diabetes, pituitary problems, and anabolic steroid use also deserve attention when relevant.

If symptoms persist, the next step is clear: ask for properly timed testosterone testing rather than guessing. If hypogonadism is confirmed, discuss the cause, fertility plans, and the real benefits and risks of treatment with an endocrinologist or urologist.

Frequently Asked Questions About How to Improve Testosterone

What is the best natural way to improve testosterone?

For men with obesity related low testosterone, losing excess weight has some of the strongest evidence. Good sleep, regular resistance exercise, enough food, management of health conditions, and correction of true nutrient deficiencies also support normal testosterone function.

How do I know if my testosterone is actually low?

A diagnosis should combine compatible symptoms with consistently low blood testosterone. Current guidance recommends at least two early morning fasting testosterone tests rather than relying on symptoms or one random result.

Does lifting weights increase testosterone?

Resistance exercise can cause short term increases in testosterone and supports muscle, metabolic health, and body composition. It should not be described as a cure for clinical hypogonadism or as a guaranteed way to permanently raise testosterone.

Does losing weight increase testosterone?

Weight loss can improve testosterone in men whose low level is linked with overweight or obesity. Current European guidance recommends lifestyle improvement and weight reduction before testosterone therapy in obesity related functional hypogonadism.

Can lack of sleep lower testosterone?

Yes. Poor or disrupted sleep can affect normal testosterone patterns. Sleep disorders are also associated with low testosterone. Loud snoring, breathing pauses, gasping, or severe daytime sleepiness should prompt consideration of sleep apnea.

Which foods increase testosterone?

No single food reliably boosts testosterone in everyone. A balanced diet that provides enough calories, protein, healthy fats, zinc, vitamin D, magnesium, and other nutrients supports normal hormone function. Correcting a deficiency matters more than eating one special food.

Should I take zinc to increase testosterone?

Not automatically. Zinc deficiency should be corrected, but high dose zinc is not a general testosterone treatment. The NIH adult upper intake level is 40 mg per day from food and supplements for people not receiving medically supervised treatment.

Should I take vitamin D for testosterone?

Treat confirmed vitamin D deficiency when appropriate, but extra vitamin D does not guarantee higher testosterone when vitamin D status is already adequate. High dose supplements can cause toxicity.

Does intermittent fasting increase testosterone?

Intermittent fasting is not a proven testosterone treatment. It may help indirectly if it supports sustainable weight loss in a man with obesity, but severe calorie restriction or poor nutrition can lower testosterone.

Does testosterone replacement therapy affect fertility?

Yes. Testosterone from outside the body suppresses pituitary signals needed for normal sperm production. Sperm counts can fall greatly or stop. Men who want children should discuss fertility before starting TRT.

Who should consider testosterone replacement therapy?

TRT may be considered when a man has symptoms of testosterone deficiency plus consistently low testosterone and an appropriate clinical diagnosis. It should not be used simply for aging, bodybuilding, energy, or athletic performance.

Is TRT safe for the heart?

Recent large trial data reduced concern about major heart attack and stroke risk in appropriately selected men, and FDA removed older boxed cardiovascular warning language. TRT still requires individualized risk assessment and monitoring because other safety questions remain.
