Shilajit is a natural phyto-mineral resin widely used in traditional medicine for its exceptional health benefits. This study presents detailed findings on Shilajit, focusing on its heavy metal content, potential toxicities, and the metal detoxification effects of the humic substances it contains. Research data was gathered from multiple scientific sources, including Google Scholar, PubMed, Science Direct, Medline, SciELO, Web of Science, and Scopus.

The study reveals that Shilajit is found in nearly 20 regions worldwide and is traditionally used to treat around 20 different health conditions. It contains various humic substances and demonstrates up to 11 biological activities. Shilajit naturally includes approximately 65 types of heavy metals, such as copper (Cu), aluminum (Al), lead (Pb), arsenic (As), cadmium (Cd), and mercury (Hg). However, its humic compounds can help detoxify around 12 of these heavy metals.

According to WHO and FDA guidelines, the permissible heavy metal levels in herbal supplements are as follows: 0.20–0.30 ppm for cadmium (Cd), 1 ppm for mercury (Hg), 10 ppm for arsenic (As) and lead (Pb), 20 ppm for copper (Cu), and 50 ppm for zinc (Zn). The studies indicate that the heavy metal content in Shilajit typically falls within these safety limits, though a few reports have shown higher concentrations.

Consuming Shilajit without verifying its metal content can pose health risks. While its humic substances may help neutralize toxic metals, further research is needed to fully understand its detoxification mechanisms.
