Joe Rogan has discussed his diet, supplements, and health practices extensively on his podcast, making him one of the most publicly documented examples of aggressive health optimisation in a man over 50. His approach is a mix of evidence-based practice and experimental biohacking — and distinguishing between the two is essential for men who want to apply what actually works.
Joe Rogan’s health routine combines elements with strong scientific support (protein-rich diet, resistance training, sauna, intermittent fasting) with more experimental practices. Men over 40 can extract significant value from his approach by focusing on the evidence-based components and applying them consistently.

His Dietary Approach
Rogan has publicly experimented with several dietary approaches, including extended carnivore diet trials, elimination diets, and periods of intermittent fasting. His default dietary approach is high in animal protein — meat, eggs, and fish — with lower carbohydrate intake relative to standard dietary recommendations. He has been particularly open about carnivore diet experiments, which he has reported improve mental clarity and reduce inflammation.
Carnivore Diet Experiments
Rogan has publicly documented carnivore diet trials — periods of eating exclusively animal products with no plant foods. He has reported improvements in energy, body composition, and inflammatory conditions (including vitiligo) during these periods. The scientific literature on carnivore diets remains limited, but the documented mechanisms for improvement — elimination of common dietary antigens, high protein intake, reduction in processed food consumption, and potential anti-inflammatory effects — are plausible. The approach is not recommended as a long-term dietary pattern for most men without medical supervision.
High-Quality Animal Protein Priority
Regardless of dietary approach, Rogan consistently prioritises high-quality animal protein — elk, bison, and wild game sourced from hunting, alongside conventional meat and fish. The emphasis on protein quantity and quality is well-supported by research for men over 40: high protein intake preserves muscle mass during ageing, supports testosterone production, and produces the satiety effect that makes caloric management sustainable. The sourcing preference for wild game reflects personal values as much as health optimisation.
His Supplement Stack — What the Evidence Says
Vitamin D3 + K2
Rogan takes high-dose vitamin D3, typically alongside vitamin K2. This combination has strong evidence support: vitamin D deficiency is extremely prevalent in men over 40, and supplementation in deficient individuals improves testosterone levels, immune function, mood, and bone density. Vitamin K2 is co-administered to support proper calcium utilisation and prevent arterial calcification that can occur with high-dose D3 supplementation.
Athletic Greens (AG1)
Rogan has been a long-term user and public advocate for AG1 (Athletic Greens), a comprehensive greens powder supplement. The formulation contains vitamins, minerals, adaptogens, probiotics, and digestive enzymes. The evidence for “greens powder” supplements as a category is mixed — individual ingredients have varying levels of support. The practical value is primarily as a convenient vehicle for micronutrient coverage and probiotic intake, rather than as a transformative supplement.
Testosterone Replacement Therapy (TRT)
Rogan has publicly disclosed that he uses testosterone replacement therapy — a medically supervised protocol that maintains testosterone levels within the physiological normal range. He has been transparent about this decision and its rationale. TRT for men with clinically confirmed low testosterone has a strong evidence base for improving body composition, energy, mood, libido, and metabolic health. It is a medical intervention that requires proper diagnostic workup and ongoing monitoring — not an over-the-counter approach.
Creatine Monohydrate
Rogan uses creatine monohydrate — one of the most extensively researched and evidence-supported supplements available. Creatine improves strength output, lean mass accumulation, and recovery from resistance training. Emerging research also supports cognitive benefits in older adults. It is one of the few supplements where the evidence base is strong enough to recommend for virtually all men over 40 who engage in resistance training.
His Health Protocols: Sauna, Cold, Fasting
Regular Sauna Use
Rogan uses an infrared sauna regularly and has discussed its benefits extensively on his podcast. The evidence base for sauna use is genuinely compelling: regular sauna use (4–7 sessions per week) is associated with significant reductions in cardiovascular mortality, improvements in growth hormone output, enhanced heat shock protein production, and improvements in endurance performance. The cardiovascular benefits appear to accumulate with frequency of use.
Cold Exposure
Cold plunge and cold shower protocols are a regular part of Rogan’s routine. Cold exposure activates brown adipose tissue, increases norepinephrine, and has documented mood-improving effects. Its effects on metabolic rate and body composition are real but modest compared to dietary and exercise interventions. The primary practical benefit for most men over 40 is the neurological and mood-enhancing effect from norepinephrine release.
Intermittent Fasting
Rogan has incorporated intermittent fasting protocols — typically time-restricted eating windows. The evidence for intermittent fasting is solid: it produces weight loss primarily through the mechanism of reducing total caloric intake, with additional benefits for insulin sensitivity and metabolic markers that are independent of the caloric effect. For men over 40, time-restricted eating is a practical approach to calorie management that does not require calorie counting.
What Men Over 40 Should Actually Apply
⚡ Evidence-Based Elements Worth Applying
- Prioritise protein at every meal — aim for 1.6–2.2g per kg of body weight daily
- Test and correct vitamin D levels — get serum 25(OH)D tested and supplement to maintain 50–80 ng/mL
- Add creatine monohydrate — 3–5g daily is one of the most evidence-supported supplements for men over 40
- Use a sauna regularly — 3–4 sessions per week produces measurable cardiovascular and recovery benefits
- Trial time-restricted eating — a 16:8 window (eating within an 8-hour period) is sustainable and effective
- Get testosterone tested — if symptoms suggest low T, blood testing is the necessary first step
- Reduce processed food — regardless of specific dietary approach, eliminating ultra-processed foods is consistently associated with improved body composition and health markers
