Testosterone is widely recognized for its role in muscle growth and puberty, but its full impact often remains unclear. While many men search online for ways to increase their testosterone—whether naturally or through supplements—the science behind the hormone’s functions and safe ways to enhance it deserves careful attention.
The Vital Role of Testosterone
Ali Malik, founder of Fit Labs Kensington, explains, “Testosterone plays a crucial role in building muscle. Low testosterone levels can lead to muscle weakness and age-related muscle loss.” Beyond muscle mass, low testosterone, or male hypogonadism, is associated with symptoms like reduced energy, diminished libido, and lower mood. With about 40% of men over 45 affected, monitoring testosterone levels becomes important as men age.
Testosterone’s influence extends beyond sexual health. Dr. Kerry Aston, founder of The Movement Medic, highlights its benefits on brain function, cardiovascular health, and body composition. “Testosterone enhances concentration and mental clarity, improves vascular function, and helps reduce abdominal fat, lowering risks for metabolic and heart disease,” she notes.
Key Benefits of Boosting Testosterone
Dr. Amy Wells, senior lecturer in exercise physiology at the University of Hertfordshire, states that boosting testosterone in deficient men can improve libido, sexual function, bone density, muscle mass, and mood. Since natural testosterone production declines from ages 25 to 30, many men fall into the category that may benefit from these boosts.
Natural Ways to Support Testosterone
Diet plays a significant role. Wells recommends foods rich in vitamin D, zinc, magnesium, and betaine—nutrients essential for testosterone production. These include:
- Beets
- Spinach
- Whole grains
- Red meat
- Seafood and oily fish like salmon and sardines
- Nuts
- Breakfast cereals
- Egg yolks
Exercise is also vital. Weight training or bodyweight circuits can temporarily elevate testosterone, while excessive cardio or chronic stress can suppress it. “Reducing stress is crucial because cortisol inhibits testosterone production,” Wells adds. “Avoid prolonged strenuous exercise like marathon running, which can lower testosterone.”
Weight loss through balanced diet and regular exercise can further support hormone balance. Aston explains that reducing excess fat lowers estrogen dominance, improves insulin sensitivity, and decreases inflammation—factors that help restore healthy testosterone levels.
However, experts caution against overly restrictive diets, particularly cutting fats, since testosterone is synthesized from cholesterol. Mike Kocsis, a personal trainer, warns, “Healthy fats and high-quality protein are necessary to maintain balanced testosterone.”
Testosterone-Boosting Supplements: Proceed with Caution
Ali Malik lists common testosterone-related supplements:
Testosterone Replacement Therapy (TRT): Synthetic testosterone to supplement or replace natural production.
Clomiphene Citrate (Clomid): Stimulates the body’s own testosterone production by blocking estrogen receptors.
Human Chorionic Gonadotropin (hCG): Mimics luteinizing hormone to stimulate testosterone production.
Anabolic Steroids: Synthetic testosterone variants, risky and illegal without prescription.
Aromatase Inhibitors: Block testosterone conversion to estrogen.
Selective Androgen Receptor Modulators (SARMs): Target androgen receptors to mimic testosterone effects, though safety and efficacy remain under investigation.
Outside medical supervision, these supplements pose serious health risks, including cardiovascular problems and liver damage. Dr. Kezia Joy emphasizes that natural methods usually suffice: “Adding eggs to your diet provides key materials for testosterone production, often eliminating the need for supplements.”
Risks of Excess Testosterone
Excessive testosterone carries dangers such as increased risk of heart attack, stroke, prostate cancer, hormone imbalances, infertility, mood changes, and acne. The FDA warned in 2014 about venous blood clots linked to testosterone product use. Wells also highlights that unregulated dietary supplements may cause serious side effects like blood thickening and worsening sleep apnea.
Moreover, increased testosterone doesn’t guarantee muscle gain, with studies showing mixed results. Men chasing muscle growth through unproven supplements risk adverse health consequences without clear benefits.
Expert Recommendations
The safest approach is to prioritize lifestyle changes—diet, exercise, stress management, and sleep—before considering supplements. Wells suggests a daily 1000 IU vitamin D supplement, backed by research, may help. Other supportive supplements include Beta‐hydroxy‐beta‐methylbutyrate (HMB), Betaine, L-Arginine, zinc, Omega-3, and herbs like fenugreek and ashwagandha, per Aston.
Ultimately, consulting a healthcare professional before starting any testosterone therapy or supplement regimen is essential to avoid harmful side effects.
