What “standardised to 50% fulvic acid” actually means

And why a bigger number on the label is usually a worse test rather than a better extract.


Shilajit is a resin, not a plant, and what it contains depends entirely on where it came from and how it was purified. Fulvic acid is the fraction most of the research is interested in, so brands state a percentage. The percentages you will see range from about 20% to, occasionally, 80% or more.

Here is the part nobody puts on a label: there is no single agreed way to measure it. Different assays return dramatically different numbers from the same material, and the methods that return the flattering numbers are generally the cheaper ones. A brand claiming 80% may be telling the truth about what its test said while telling you very little about what is in the jar.

This matters more than it sounds. Published analysis of commercial shilajit products found that fewer than two-thirds contained measurable fulvic fractions at all. Not underdosed — absent.

Ours is stated at a minimum of 50%, which is deliberately unspectacular. It is the standardisation used by the material in the published human research, it is verified per batch, and we name the method used to verify it. If someone shows you a higher number, the useful question is not whether it is higher. It is which assay produced it.
