What Is Fulvic Acid, and What Does “75%” Mean?
Fulvic acid is the number most shilajit labels lead with. Here is what it is and how to read the percentage.

What it is
Fulvic acid is not a single molecule. It is a family of small organic compounds that form when plant matter breaks down over a very long time. It is found in soil, in peat and, in concentrated form, in shilajit. Together with humic acid it makes up the “humic substances” that are the bulk of purified shilajit.
Why labels print a percentage
Natural material varies. One batch of shilajit can contain much more fulvic acid than another. Standardizing means the maker adjusts and tests the extract so that every batch contains a stated share. A label that says a product is standardized to a percentage is telling you that share is controlled rather than left to chance.
Alloza uses shilajit standardized to 75% fulvic acid: of the 400 mg of shilajit in a serving, three quarters is fulvic acid.
Is a higher percentage better?
It is a marker of concentration and consistency, which is useful when comparing products. But be careful with comparisons: different labs measure fulvic acid by different methods, and the results are not always interchangeable. The percentage also means little without the milligrams of shilajit it applies to, so read both numbers together.
What research says
Fulvic acid is studied mainly for its role in how nutrients are taken up,* and most of that work is in the laboratory or in animals. Human studies are few; a 2018 review in the Journal of Diabetes Research (Winkler and Ghosh) summarizes the field and calls for more of them. The human trials on shilajit itself, such as Keller et al., 2019, used whole purified shilajit, not isolated fulvic acid.
A related idea is pairing ingredients to help absorption. The classic example is piperine from black pepper, which raised the absorption of a companion compound in human volunteers (Shoba et al., 1998).* Alloza includes 2 mg of piperine per serving.
What “trace minerals” means
Shilajit carries many minerals, but in trace amounts, meaning very small quantities. The “92+ trace minerals” on our pouch describes that variety. It is not a replacement for a multivitamin or for the minerals you get from food.
Reading a label in three steps
- Find the milligrams of shilajit per serving.
- Find the fulvic acid percentage it is standardized to.
- Find the independent lab report. See heavy metals and lab testing.
