Shilajit

Shilajit is a 7.0–7.5/10 fit for men testing fertility, testosterone, energy, or mineral-resin support with a purified, contaminant-tested product, not a universal adaptogen or detox cure. The cleanest evidence anchors are Pandit 2016, which reported testosterone and DHEAS increases after 500 mg per day for 90 days, and Biswas 2010, which reported improved sperm parameters in oligospermic men. Keller 2019 adds useful context: found better preservation of fatigue-related strength at higher dose. The practical gap is the same one that shows up across the report: mechanism and early outcomes are more convincing than broad real-world certainty. In practice, Shilajit belongs after the basics, works best when the target is specific, and deserves tracking around benefits, side effects, interactions, and cost before it becomes a standing protocol.

✅ Best for: Adults who want a broad, slow-acting supplement for testosterone support, male fertility support, strength retention, collagen turnover, bone-density preservation, or steady energy, and who are willing to use purified shilajit with current heavy-metal testing. Shilajit fits best as an adjunct to resistance training, fertility workups, bone-health basics, and mitochondrial stacks such as creatine, CoQ10, protein, minerals, and sleep. It is most evidence-matched for 8-48 week protocols, not one-week experiments.

❌ Avoid if: You are pregnant, breastfeeding, have hemochromatosis, hormone-sensitive cancer, bleeding disorders, uncontrolled diabetes medication changes, upcoming surgery, or a history of reacting poorly to androgen-support supplements. Avoid raw or unverified resin entirely. Also avoid using shilajit as a substitute for guideline-based care: the AUA/ASRM male infertility guideline and Endocrine Society testosterone guideline do not recommend shilajit, and WADA caution still applies to supplement contamination even when the ingredient is not named on the prohibited list.
