In short
- Request the original report for a claimed content.
- Check whether the statement refers to raw material or end product.
- Don't rank products solely by the highest number.
Ask how the measurements were taken
When a supplier claims a content, we ask for the original report and the measuring method used. Without that background, we do not include a percentage in the product presentation. The Eurachem/CITAC guide provides general background on analytical methods and measurement quality; he does not identify an ideal fulvic acid percentage for shilajit.
No quality score in itself
A level does not indicate whether a batch has also been examined for relevant contaminants and microbiology. Our assessment combines the product specification with the control plan and batch documentation.
Our first specification follows
No definitive content has yet been determined for Shilajit Select. There is therefore no fulvic acid percentage on our concept packaging or product page.
What information do we request?
For a stated percentage, we ask the supplier for the original document, the identification of the sample, the date and the measuring method. We also want to know how the outcome is linked to the product specification and sales batch.
We do not accept a number without this information. This also applies if the same percentage appears frequently on other websites: repetition is not a substitute for a report of the specific product.
When is an equation incomplete?
Two percentages seem easy to compare, but without sufficient information about the material and the method of measurement, this comparison cannot be made responsibly. We then leave the difference open instead of designating one product based on that number as better.
Even with well-described percentages, other questions remain. What is the total composition? What additional checks have been made? Is the documentation linked to the batch that is actually delivered?
How do we communicate a future specification?
Only when the product and the associated substantiation have been established can we assess which composition information belongs on the label and the website. That information must be consistent with the documentation.
A percentage does not become a general promise about effectiveness. This page describes our assessment approach; fulvic acid content for Shilajit Select has not yet been determined.
