Shilajit is a tar-like exudate found seeping from rock strata at high altitudes in the Himalayas, Altai, Caucasus, and other mountain ranges, formed from centuries of compression and humification of plant material. It has been a cornerstone of Ayurvedic medicine for over 3,000 years, historically classified as a rasayana — a rejuvenating substance believed to promote longevity and vitality. Modern analysis has identified fulvic acid (comprising 60–80% of its bioactive content) and dibenzo-alpha-pyrones as the primary pharmacologically active constituents.

Fulvic acid acts as a potent electron carrier and facilitates mitochondrial energy production by enhancing electron transport chain efficiency, which may explain reported improvements in physical energy and reduced fatigue. Dibenzo-alpha-pyrones and their chromoprotein complexes appear to protect dopaminergic neurons, support acetylcholine synthesis, and modulate inflammatory signaling. Shilajit also appears to regulate gonadotropins at the pituitary-hypothalamic axis, which may account for its observed effects on testosterone levels in men.

Purified resin dissolved in warm water or milk is considered the most bioavailable form and most consistent with traditional use. Capsule and powder forms vary significantly in quality and standardization — look for products with documented fulvic acid percentage, heavy metal testing, and ideally third-party certification. Some products list 'PrimaVie' as a branded, clinically studied standardized extract. Avoid raw or unprocessed shilajit, which may carry safety risks from contamination.

• Low Testosterone
• Physical Fatigue and Exercise Performance
• Cognitive Decline
• Altitude Sickness
• Iron Deficiency Anemia

• Testosterone decline with aging (supported by limited RCT evidence in middle-aged men)
• Exercise-induced muscle strength loss (supported by one RCT with standardized extract)

• Gastrointestinal discomfort (nausea, loose stools) — more common when taken on an empty stomach
• Dizziness or lightheadedness — reported rarely, possibly related to trace mineral load or mild blood pressure effects
• Potential heavy metal exposure — risk is specific to unpurified or unverified products
• Increased uric acid levels — some mineral components may theoretically elevate uric acid; caution in patients with gout
• Hormonal changes — due to testosterone-supporting activity, not recommended in hormone-sensitive conditions (prostate cancer, breast cancer) without medical supervision
• Rash or allergic reaction — rare, reported in isolated cases

• Recommended daily: 300–500 mg/day of purified, standardized shilajit (minimum 50% fulvic acid); the most studied dose in RCTs is 250 mg twice daily (500 mg total) or 500 mg once daily
• Best time of day: Morning, or split morning/evening dosing if using 500 mg/day; some practitioners suggest taking alongside breakfast or a fat-containing meal to support absorption of fat-soluble DBP constituents
• With or without food: Best taken with food or warm milk/water to improve gastrointestinal tolerance and potentially enhance absorption of lipophilic constituents; traditional use was dissolved in warm milk
• Time to effect: Testosterone and hormonal effects: 8–12 weeks; Energy and fatigue reduction: 4–8 weeks; Cognitive support: effects may require 12+ weeks
• How long to take it: Clinical trials have studied continuous use for up to 90 days. Long-term use beyond 3 months is common in traditional practice but lacks robust controlled safety data. A cycling approach (e.g., 8–12 weeks on, 4 weeks off) is a reasonable precaution. Not recommended during pregnancy or breastfeeding due to insufficient safety data.
