- 1Check deficiency and basics
Start with nutrients where deficiency status changes the interpretation.
- 2Review single ingredients
Compare the clinical evidence before buying into claims.
- 3Build or avoid a stack
Use these when combining supplements or weighing DHT/BPH-adjacent claims.

Tier 1 · SupplementsVitamin D and Testosterone: Reconciling Correlation with Causal Evidence
Observational studies link low vitamin D to low testosterone, but interventional trials largely fail to show a causal effect. Deficiency thresholds matter.
Tier 1 · SupplementsShilajit and Testosterone: Clinical Evidence vs. Marketing Claims
Purified Shilajit 250mg twice daily increases total testosterone by 20% in healthy men, but evidence is limited to one small RCT.
Tier 1 · SupplementsFinasteride for Hair Loss: Evidence, Side Effects, and the PFS Debate
Finasteride 1mg reduces DHT by 65–70% and slows hair loss in most men. Side effects are real but low-frequency. Post-finasteride syndrome remains contested.
Tier 1 · SupplementsSaw Palmetto: Evidence for DHT Inhibition, BPH, and Hair Loss
Saw palmetto is marketed for BPH and hair loss via DHT inhibition. The evidence for BPH is mixed; the evidence for hair loss is weaker than for finasteride.
Tier 1 · SupplementsTribulus Terrestris and Testosterone: Reviewing the Evidence
Tribulus is one of the best-selling testosterone supplements. Human clinical trials consistently fail to show meaningful testosterone increases.
Tier 1 · SupplementsTongkat Ali and Testosterone: A Review of the Clinical Evidence
Tongkat ali is one of the most researched testosterone herbs. Multiple RCTs exist. Here's what the evidence actually shows about dose, timing, and who benefits.
Tier 1 · SupplementsDHEA Supplementation in Men: What 40 Years of Research Shows
DHEA declines sharply after 30. Supplementation shows real hormonal effects — but clinical benefits are more complicated than supplement labels imply.
Tier 1 · SupplementsFenugreek and Testosterone: What the Clinical Evidence Shows
Fenugreek is one of the most studied testosterone herbs. Here's what RCTs actually show about dosing, mechanisms, and who benefits most.
Tier 1 · SupplementsAshwagandha for Testosterone and Stress: Clinical Evidence Review
KSM-66 ashwagandha reduces cortisol by ~28% and raises testosterone in stressed men. More RCT evidence than any other adaptogen. Dose, timing, and limitations.
Tier 1 · SupplementsBoron and Testosterone: The Overlooked Mineral with Real Evidence
Boron raises free testosterone, lowers SHBG, reduces estradiol, and amplifies vitamin D. The evidence is stronger than its reputation. Dose is just 6–10 mg/day.
Tier 1 · SupplementsCreatine and Testosterone: What the Studies Actually Show
Creatine's testosterone effects are real but indirect. The DHT elevation data is more interesting than most coverage suggests. Dosing and mechanism explained.
Tier 1 · SupplementsOmega-3 Fatty Acids and Male Hormonal Health: What the Evidence Shows
Omega-3s reduce inflammation, support testosterone, and improve sperm quality. EPA and DHA have different roles — source quality and dosing both matter.
Tier 1 · SupplementsMale Health Supplement Stack: Evidence-Based Combinations
Most supplement stacks ignore interaction effects and redundancy. This guide builds from evidence up — what to take, in what order, and what to skip.
Tier 1 · SupplementsMagnesium Deficiency in Men: The Mineral Most Blood Tests Miss
Serum tests miss 80% of magnesium deficiency. RBC magnesium is the correct test. Deficiency affects testosterone, sleep, and muscle — prevalence is 45%.
Tier 1 · SupplementsVitamin D Deficiency and Testosterone: The RCT Evidence
A placebo-controlled RCT found 25% testosterone increase with vitamin D in deficient men. Who benefits, correct dose, and why most testing misses deficiency.
