Andropause / Men 50+
About this protocol
Where to start
Get baseline labs first. Morning (8-10 AM) draw for total + free testosterone, SHBG, LH, FSH, estradiol, PSA, fasting lipid panel (including ApoB if available), fasting glucose, and CBC. Repeat the testosterone on a separate morning to confirm — single-draw variability is meaningful.
If total testosterone is below 300 ng/dL on two morning draws with symptoms, that is an endocrinology conversation, not a supplement question. Ask about TRT candidacy, fertility implications, and prostate/cardiovascular workup. This protocol is not a substitute.
Start with vitamin D3 and ashwagandha (KSM-66) as the foundational layer. Both have direct trial evidence in aging men and address common deficiencies.
Add zinc if dietary intake is low (older men commonly underconsume) or absorption is reduced. This is a deficiency-correction nutrient, not a stack-amplifier.
Tongkat ali and boron are the complementary/experimental tier. Tongkat ali has the strongest trial signal of any "T-supporting" botanical, but the literature is dominated by smaller Southeast Asian trials. Boron is the most speculative — a structured 8-12 week trial is reasonable.
Recheck labs after 12-16 weeks on a stable stack. If numbers and symptoms have not moved meaningfully, escalate to endocrinology rather than stacking more supplements.
Beware "T-boosting" marketing. Most products are under-dosed proprietary blends or use ingredients with no human trial evidence. Stick to clinically-tested doses of single ingredients with PubMed-indexed trials.

Strongest evidence — the foundation of the stack.
Ashwagandha (KSM-66)
600 mg, with breakfastAshwagandha (Withania somnifera, standardized KSM-66 extract) has the most directly relevant trial evidence for this population: Lopresti 2019 in aging, overweight men showed modest 8-week increases in testosterone and DHEA-S alongside subjective vitality improvements. The mechanism is HPA-axis modulation rather than direct testicular stimulation — meaningful for older men whose elevated chronic cortisol competes with testosterone for shared precursor pathways. Not a substitute for solving underlying stress sources.[1, 2]
Vitamin D3
2000-4000 IU daily, with breakfastVitamin D acts as a steroid-hormone precursor and receptor-modulator. Observational data link low 25-OH vitamin D with lower testosterone in men, and Pilz 2011 (one-year RCT in vitamin-D-deficient men) showed supplementation raised total testosterone over the trial period. The effect is largest in the deficient and insufficient range — replete men do not see further increases. Target 30-50 ng/mL on lab. Fat-soluble; take with a fat-containing meal.[3, 4]
Add if needed
Add these only if the foundation isn't enough.
Tongkat Ali (Eurycoma longifolia)
200-400 mg standardized extract daily, with breakfastTongkat ali (Eurycoma longifolia) has the strongest trial signal of any classic 'T-supporting' botanical: Tambi 2012 in late-onset hypogonadism showed improvements in testosterone and symptom scores, and Talbott 2013 showed reductions in cortisol alongside testosterone improvements in moderately stressed men. The literature is dominated by smaller Southeast Asian trials and needs broader replication, but quality is markedly higher than typical 'T-booster' snake oil. Worth a 12-week structured trial with measurable endpoints.[5, 6, 7]
Zinc
15-30 mg elemental, with breakfastZinc is essential for testosterone biosynthesis, and Prasad 1996 established that severe zinc deficiency demonstrably suppresses testosterone in human studies. Most relevant for older men with dietary restriction, reduced absorption (common after 60), or vegetarian/vegan diets. In replete men, additional supplementation does not raise testosterone further — this is a deficiency-correction nutrient, not a stack-amplifier. Picolinate and bisglycinate forms are well-absorbed. Do not exceed 40 mg/day for extended periods (chronic high zinc depletes copper).[8, 9]
Experimental
Emerging evidence — try last, only if curious.
Boron
5-10 mg daily, with breakfastBoron is a trace mineral with small human trials (Naghii 2011) suggesting effects on free testosterone via SHBG modulation and reductions in estradiol. The studies are small and short — treat as the most speculative item in this stack. Generally well-tolerated. A structured 8-12 week trial alongside before/after lab work is the reasonable way to evaluate personal response.[10, 11]
Warnings
Lifestyle improvements
Strength training is non-negotiable
2-3 sessions per week of heavy compound lifts (squat, deadlift, press, row, pull-up variants) is the single highest-leverage intervention for testosterone, muscle mass, bone density, and metabolic health in men over 50. Cardio alone does not move testosterone or preserve muscle. If you have not lifted before, hire a coach for the first 8-12 weeks to learn the patterns safely.
Zone 2 cardio for cardiovascular health
90-150 minutes per week of conversational-pace aerobic work (brisk walk, easy cycle, easy row) supports cardiovascular health and insulin sensitivity without competing with strength adaptations. Stack with strength training, do not replace it.
Sleep 7-9 hours, prioritize REM
Testosterone is produced primarily during REM sleep. A single week of restriction to 5 hours suppresses testosterone by 10-15% in healthy men, and chronic insufficiency in older men is widespread and under-diagnosed. Sleep apnea risk rises sharply after 50 and after weight gain — a sleep study is worth pursuing if you snore, wake unrefreshed, or have morning headaches.
Body composition matters more than supplements
Excess adipose tissue, especially visceral fat, increases aromatase activity (testosterone → estradiol conversion). Losing 5-10% of body weight in overweight men reliably raises testosterone. This is consistently a larger lever than any supplement in this stack.
Limit alcohol
Heavy alcohol intake suppresses LH and direct testicular function, and metabolic clearance slows with age. Moderate intake (1-2 drinks max, not daily) has minimal hormonal effect for most men, but the cardiovascular and sleep-quality cost rises after 50.
Annual PSA and digital rectal exam after 50
Prostate health screening becomes essential in this decade. Establish a baseline PSA and trend it annually. Any testosterone-modulating intervention (supplement or TRT) makes baseline + trend monitoring more important, not less.
Cardiovascular screening
Lipid panel, ApoB if available, blood pressure, fasting glucose, HbA1c. Coronary calcium score (CAC) once in the 50s is worth discussing — it stratifies risk far better than lipids alone. Any TRT discussion should include cardiovascular workup; the topic is nuanced and benefits proper assessment.
Mental health support
Mood changes (depression, irritability, withdrawal) are a real feature of andropause and not just "getting older." If symptoms persist beyond lifestyle and supplement intervention, screen for depression formally. Therapy, exercise, and — if indicated — pharmacotherapy are appropriate. Do not normalize emotional flatness as inevitable aging.
Annual labs
Track total + free testosterone, SHBG, LH, FSH, estradiol, PSA, lipid panel, fasting glucose, HbA1c, CBC. Numbers and symptoms together drive the decision tree — neither alone is sufficient.
