The most effective ways to support healthy testosterone naturally are lifestyle-based: maintain a healthy weight (excess fat lowers testosterone), do regular exercise including strength training, get 7-9 hours of quality sleep (testosterone is largely made during sleep), manage chronic stress (which raises cortisol and suppresses testosterone), and eat well with enough zinc and vitamin D. These do far more than 'testosterone-boosting' supplements, most of which don't meaningfully raise testosterone.
"Boost your testosterone" is one of the biggest marketing hooks in men's health, but the most effective ways to support healthy levels are lifestyle-based. Weight management, exercise, sleep, stress control, and correcting nutrient deficiencies have stronger support than most so-called testosterone boosters.
First, an Honest Reality Check
Before the methods, two points. First, natural approaches optimise testosterone within your normal range and help prevent lifestyle-driven declines - they won't turn normal levels into extraordinary ones, and they aren't a treatment for medically low testosterone (which needs a doctor). Second, most "testosterone-boosting" supplements don't work as advertised: ingredients like tribulus don't raise testosterone, and others (zinc, vitamin D) help mainly by correcting deficiencies. So the real leverage is in lifestyle.
1. Maintain a Healthy Weight
This is one of the most impactful factors. Excess body fat - especially abdominal fat - lowers testosterone, partly by converting it to estrogen. Studies show that losing excess weight can meaningfully raise testosterone in overweight men. If you carry extra weight, losing it through diet and exercise is likely the single most effective natural way to support your testosterone.
2. Exercise - Especially Strength Training
Resistance training (lifting weights, bodyweight exercises) supports healthy testosterone and builds the muscle that improves body composition and metabolic health. High-intensity interval training may also help. And general activity supports healthy weight and reduces fat. Exercise is a cornerstone of natural testosterone support - see our exercise guide.
3. Prioritise Sleep - This Is Huge
Here's a fact many men don't realise: testosterone is largely produced during sleep, particularly deep sleep. Chronic sleep deprivation significantly lowers testosterone - studies show that restricting sleep to around 5 hours a night can reduce young men's testosterone by 10-15% in just a week. Aim for 7-9 hours of quality sleep. If you do only one thing for your testosterone, fixing poor sleep may be it. Also consider getting checked for sleep apnea, which harms both sleep and hormones.
4. Manage Chronic Stress
Chronic stress elevates cortisol, and cortisol and testosterone have an inverse relationship - sustained high cortisol suppresses testosterone. Chronic stress also disrupts sleep and drives unhealthy habits. Managing stress through exercise, relaxation practices, time in nature, hobbies, social connection, or professional support helps your hormonal health (and your libido and mood). See our stress and libido guide.
5. Eat Well and Correct Deficiencies
A balanced diet supporting a healthy weight is the foundation. Two nutrients are specifically important for testosterone - but mainly if you're deficient:
- Zinc: important for testosterone; deficiency lowers it. Found in oysters, shellfish, meat, and pumpkin seeds.
- Vitamin D: linked to testosterone; many people are deficient, especially in winter. Sunlight, fatty fish, and (if deficient) supplementation help.
Also ensure you're eating enough and getting enough healthy fats and protein - crash diets and very low-fat diets can lower testosterone. Avoid excessive alcohol, which reduces testosterone.
6. Limit Alcohol and Avoid Other Testosterone Killers
Excessive alcohol lowers testosterone and harms sleep and vitality. Also worth minimising: chronic excessive stress, smoking, and a sedentary lifestyle. These lifestyle factors, together, have a bigger impact than any supplement.
What About Testosterone Supplements Like Those in Erexafil?
temper your expectations. As covered in our testosterone guide, most "test booster" ingredients don't meaningfully raise testosterone. In Erexafil, ashwagandha showed a modest effect in one study, zinc and D3 help if you're deficient, but tribulus doesn't work, and DHEA is a hormone requiring caution. A supplement might offer marginal support at best - the lifestyle factors above do the real work. If you suspect low testosterone, see a doctor for testing rather than relying on a supplement.
Important: If you have symptoms of low testosterone (persistent low libido, fatigue, low mood), see a doctor for proper testing - the symptoms overlap with many treatable conditions. Don't self-treat with supplements. Erexafil contains DHEA, a hormone with real cautions; consult a doctor before use, especially with a prostate or hormone-sensitive condition or if you take medication.
