Shilajit
Shilajit (Fulvic Acid Complex)
Shilajit is a blackish-brown resinous substance found in high-altitude mountain rocks, particularly the Himalayas, formed over centuries by the decomposition of plant and microbial matter. It contains over 85 minerals in ionic form, fulvic acid (typically 60-80% of active compounds), dibenzo-alpha-pyrones, and various humic substances. It is primarily used as an adaptogen and mitochondrial enhancer, with clinical interest in testosterone support, cognitive function, energy metabolism, and male fertility.
Mechanism of Action
Fulvic acid and dibenzo-alpha-pyrones in shilajit act as electron carriers, enhancing mitochondrial Complex I and II activity, thereby improving ATP synthesis and cellular energy production. Fulvic acid also chelates heavy metals and facilitates nutrient transport across cell membranes, while dibenzo-alpha-pyrones help preserve CoQ10 in its reduced, active form (ubiquinol). Additionally, shilajit modulates gonadotropin activity and reduces oxidative stress via upregulation of endogenous antioxidant enzymes, contributing to its testosterone-supporting and neuroprotective effects.

Dosing Protocols
With meals, preferably in the morning
Cycle: 8-12 weeks on, 4 weeks off
Use purified, standardized resin or extract with verified fulvic acid content (minimum 50%). Resin form dissolved in warm water or milk is considered the most bioavailable. Avoid raw/unpurified shilajit due to heavy metal and mycotoxin contamination risk. Benefits for testosterone and energy typically noted after 4-8 weeks of consistent use.
Safety & Side Effects
Purified, standardized shilajit is generally considered safe for healthy adults at recommended doses, with a reasonable human use history spanning centuries in Ayurvedic medicine. However, product quality is the primary safety concern — unpurified sources carry significant heavy metal and mycotoxin contamination risks, and individuals with hemochromatosis, gout, hormone-sensitive conditions, or pregnancy should avoid use or consult a physician prior.
Possible Side Effects
- !Gastrointestinal discomfort, nausea, or loose stools, particularly at higher doses or on an empty stomach
- !Elevated uric acid levels with prolonged use, potentially exacerbating gout
- !Increased iron levels, which may be problematic in individuals with hemochromatosis
- !Dizziness or lightheadedness, possibly due to blood pressure-lowering effects
- !Allergic reactions including rash or itching in sensitive individuals
- !Heavy metal toxicity (arsenic, lead, mercury) if using unpurified or low-quality products
- !Potential hormonal fluctuations, including transient increases in androgen activity
Interactions
- -May potentiate anticoagulant and antiplatelet medications (e.g., warfarin, aspirin) due to fulvic acid's effects on platelet aggregation
- -Can lower blood pressure — use caution when combined with antihypertensive drugs
- -May increase iron absorption and serum iron levels — avoid concurrent use with iron supplements in individuals prone to iron overload
- -Potential additive effects with testosterone-boosting supplements (e.g., ashwagandha, fenugreek) — monitor for androgenic side effects
- -May interact with diabetes medications by enhancing insulin sensitivity, potentially causing hypoglycemia
Cost & Where to Buy
Price varies significantly by form (resin vs. capsule), purity certification, and brand. High-quality purified resin with third-party heavy metal testing commands a premium. Budget options from uncertified sources carry quality and safety risks and should be avoided.
