How to Naturally Increase Testosterone: What Works

What controls testosterone levels in the body?

Testosterone is produced primarily in the testes (in men) under control of the hypothalamus and pituitary gland. It follows a daily rhythm, peaking in the morning and declining through the day. Levels change naturally with age — a gradual decline begins in most men around their mid-30s to 40s. Low testosterone, when it causes symptoms, is called hypogonadism. The Endocrine Society's clinical practice guideline recommends confirming a low testosterone diagnosis with two early-morning blood tests before considering treatment 1Ref 1Bhasin S, Brito JP, Cunningham GR, Hayes FJ, Hodis HN, Matsumoto AM, Snyder PJ, Swerdloff RS, Wu FC, Yialamas MA (2018).Testosterone Therapy in Men With Hypogonadism: An Endocrine Society Clinical Practice Guideline.Recommendation to confirm low testosterone with two early-morning blood tests and diagnostic criteria for hypogonadism.

Which lifestyle habits have the strongest evidence?

Sleep is probably the single most important recoverable factor. Most testosterone release happens during sleep, particularly during the deeper stages. Studies consistently show that restricting sleep to five or fewer hours per night substantially reduces daytime testosterone levels. Seven to nine hours per night is the evidence-based target for adults 2Ref 2Watson NF, Badr MS, Belenky G, et al. (2015).Recommended Amount of Sleep for a Healthy Adult: A Joint Consensus Statement of the American Academy of Sleep Medicine and Sleep Research Society.Evidence basis for 7–9 hours of sleep per night as the target for adult health, relevant to hormonal regulation.

Resistance training (strength training) acutely raises testosterone and, over time, improves body composition in ways that support hormonal health. Compound movements involving large muscle groups — squats, deadlifts, rows, presses — appear to produce the largest hormonal response. The WHO recommends muscle-strengthening activity involving all major muscle groups on at least two days per week 3Ref 3Bull FC, Al-Ansari SS, Biddle S, et al. (2020).World Health Organization 2020 guidelines on physical activity and sedentary behaviour.Recommendation for muscle-strengthening activity on at least two days per week as part of evidence-based physical activity guidelines.

Maintaining a healthy body weight matters because excess body fat, particularly abdominal fat, increases conversion of testosterone to estrogen through an enzyme called aromatase. Losing even a modest amount of weight when overweight can produce meaningful improvements in testosterone levels.

Managing chronic stress supports hormonal balance. Chronically elevated cortisol — the stress hormone — suppresses the hormonal signal that triggers testosterone production. Stress reduction strategies, adequate sleep, and regular physical activity all help.

What about diet — do certain foods raise testosterone?

No single food has a clinically meaningful effect on testosterone. What diet does is provide the building blocks hormone production requires and avoid conditions (like excess body fat or nutrient deficiency) that suppress it.

Nutrients worth ensuring you get enough of: - Zinc: needed for testosterone synthesis; found in meat, shellfish, legumes, and seeds - Vitamin D: adequate levels correlate with healthy testosterone; produced in skin with sun exposure and found in fatty fish and fortified foods - Healthy fats: dietary fat is a precursor to steroid hormones; extremely low-fat diets may modestly reduce testosterone

Excessive alcohol reliably reduces testosterone over time by impairing the testes directly and increasing cortisol.

Do testosterone-boosting supplements work?

The short answer is that most do not, at least not in men with normal testosterone levels. Products marketed as natural testosterone boosters — fenugreek, ashwagandha, D-aspartic acid, DHEA — have limited, inconsistent, or methodologically weak evidence. Some show small effects in men who are deficient in a particular nutrient (like zinc or vitamin D); those same effects do not usually appear in men who are already replete.

DHEA and testosterone precursors sold as supplements are also unregulated in terms of actual content, purity, and dose. The AUA guideline on testosterone deficiency does not endorse any over-the-counter supplement as a treatment 4Ref 4Mulhall JP, Trost LW, Brannigan RE, Kurtz EG, Redmon JB, Chiles KA, Lightner DJ, Miner MM, Murad MH, Nelson CJ, Platz EA, Ramanathan LV, Lewis RW (2018).Evaluation and Management of Testosterone Deficiency: AUA Guideline.AUA guideline on diagnosis and management of testosterone deficiency, basis for noting lack of endorsement of OTC supplements.

If your testosterone is genuinely low and causing symptoms, prescription testosterone replacement therapy (TRT) is a well-studied option — but it comes with its own risks and monitoring requirements that require a clinician's ongoing involvement 5Ref 5Jaiswal V, Sawhney A, Nebuwa C, Borra V, Deb N, Halder A, Rajak K, Jha M, Wajid Z, Thachil R, Bandyopadhyay D, Mattumpuram J, Lavie CJ (2024).Association between Testosterone Replacement Therapy and Cardiovascular Outcomes: A Meta-analysis of 30 Randomized Controlled Trials.TRT as a studied treatment with known cardiovascular considerations requiring clinician-supervised monitoring.

When should you get your testosterone checked?

Consider asking a clinician for a testosterone test if you have symptoms that have persisted for several months: persistent fatigue, reduced sex drive, difficulty building or maintaining muscle despite training, low mood, or reduced morning erections. These symptoms have many possible causes — thyroid dysfunction, sleep apnea, depression, and other conditions all mimic low testosterone — and a blood test is the only way to know which it is.

A Gale primary care clinician can order the appropriate labs, interpret results in the context of your overall health, and discuss options — lifestyle, further evaluation, or referral to an endocrinologist or urologist if TRT is being considered.
