Safety Profile

Overall safety rating: Safe with Caution

Potential Side Effects

  • Generally well-tolerated in purified forms
  • Mild digestive discomfort (uncommon)
  • Unpurified/raw shilajit may contain heavy metals (lead, arsenic, mercury) — only use purified products
  • May increase uric acid levels — use caution with gout
  • May lower blood pressure — monitor if already on antihypertensives

Drug & Supplement Interactions

  • May enhance the absorption and effectiveness of CoQ10 and other nutrients due to fulvic acid's transport properties
  • Iron supplements — fulvic acid enhances iron absorption; use caution with iron overload conditions
  • Blood pressure medications — shilajit may have additive hypotensive effects
  • Diabetes medications — some evidence suggests blood sugar-lowering effects; monitor glucose levels

Maximum Dose

Do not exceed: No established UL; doses up to 500mg daily used safely in 90-day studies
