Open any Shilajit listing and you will find a percentage of fulvic acid, often as the headline. It looks like a quality score. It is not one, and it helps to know why before you put a number on your pack.
There is no single standard to quote
Shilajit does not have a single, widely accepted numeric standard that a buyer can simply quote. Published and marketed figures for fulvic acid vary widely, and much of the variation comes from how the result was measured and which form of product was tested, not only from the material itself.
The method matters
Different laboratories use different methods to estimate fulvic acid. Two methods can return different numbers for the same sample. So a figure on a certificate of analysis is only meaningful alongside the method used, and ideally the batch it was run on.
Resin, liquid and capsules are not comparable
A figure for a dry extract is not comparable with a figure for a wet resin or a liquid, because moisture and other components change the result. Compare like with like, or do not compare.
What to ask for
- The method used, named on the certificate
- The batch number the result belongs to
- The laboratory that ran it
- The other tests on the same certificate, especially heavy metals and microbial limits
What this means for your label
Printing a fulvic acid percentage on your pack makes it a claim that you must be able to support batch after batch. Many brands are better served by an accurate description of the product and the way it is made. We would rather help you write a label that holds up than one that looks impressive for a quarter.
