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.

heavy metals: real-world concentration context
Trace amounts of heavy metals are naturally present throughout the environment and are not unique to shilajit. They occur in soil, water & plants and are routinely detected at low levels in a wide range of commonly consumed foods.
Published testing data and regulatory monitoring programs commonly report approximate ranges such as:
- leafy greens (spinach, kale): lead & cadmium often detected in the 0.01–0.2 mg/kg (ppm) range.
- rice and grains: inorganic arsenic commonly detected in the 0.05–0.3 mg/kg (ppm) range.
- cacao and chocolate: lead and cadmium frequently detected in the 0.1–1.0+ mg/kg (ppm) range.
- spices and herbal products: heavy metals can vary widely depending on source, with some testing results exceeding 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 measured in parts per million (ppm) or parts per billion (ppb).
