certificates of analysis
at Shilala, transparency matters.
this page provides access to our Certificates of Analysis (COAs), which document third-party laboratory testing for ingredient purity, safety, and quality standards. each COA reflects independent testing conducted by accredited laboratories and may include results for heavy metals and other contaminant screening.
these reports are shared so you can review the data directly and make informed decisions.
LOT_004R has been used to batch from March 2025-present.
about heavy metals & context
trace amounts of heavy metals are naturally present throughout the environment and are not unique to shilajit. they occur in soil, water, and plants, and they are routinely detected at low levels in a wide range of commonly consumed foods.
for general context, published testing data commonly reports approximate ranges such as:
- leafy greens (ie kale & spinach): lead and cadmium are often detected in the ~0.01–0.2 mg/kg (ppm) range.
- rice and other grains: inorganic arsenic is commonly detected in the ~0.05–0.3 mg/kg (ppm) range.
- cacao and chocolate: lead and cadmium are often detected in the ~0.01–1.0+ mg/kg (ppm) range.
- spices and herbal products: levels can vary widely by origin and processing, and some testing has reported results above 1.0 mg/kg (ppm).
what matters is concentration in relation to established safety limits, not the presence of trace amounts alone. modern laboratory methods are highly sensitive and can detect extremely small quantities, often reported in parts per million (ppm) or parts per billion (ppb). certificates of analysis provide the measured values so they can be evaluated responsibly and transparently.
shilajit & heavy metals
shilajit forms in nature over long periods of time as plant material and minerals break down and interact with the surrounding environment. during this process, it can absorb substances from the soil and rock around it in a way that’s similar to how plants do.
leafy greens, for example, pull nutrients from the soil through their roots, but they can also absorb trace amounts of naturally occurring heavy metals that are present in that soil.
shilajit behaves in a comparable way - it comes from natural geological and biological processes & can take on both beneficial minerals and trace environmental elements from its surroundings. this doesn’t automatically make it unsafe, but it does mean that sourcing, purification, and third-party testing matter.
independent lab testing helps confirm that any naturally occurring elements remain at levels considered acceptable for consumption, which is why transparent Certificates of Analysis are important when evaluating shilajit products.
