- Nine yes/partial/no checks, each based on a document or a first-hand check.
- A brand’s score is the number of checks confirmed, out of nine.
- The index measures transparency, not health effects or taste.

Nature Elixirs: business, origin, processing and laboratory details from its published production page and AGROLAB report for batch SJ2509;[2][3] jar match checked first-hand by our team. Check 9 is partial because composition comes from an earlier sample and inorganic arsenic testing is planned.[4][2]
Why transparency matters
Shilajit forms in contact with rock, so contaminant levels vary from batch to batch,[5] and GB law sets maximum levels for lead, cadmium and mercury in supplements.[6] A brand that names its laboratory, batch and results lets you check those things for yourself. The index rewards exactly that.
How brands are added
