How much fulvic acid is in shilajit depends on the product and on what the percentage is measured against. In 2024 ConsumerLab reported 6.9 mg to 2,206 mg per serving across eight products and said labels typically do not list it. To compare two labels, multiply the percentage by the serving weight in mg.
We sell one shilajit product, Satiovex Himalayan Shilajit Resin in a 30 g pot, so this is a seller's page. It states no fulvic acid figure for that pot and does not say what fulvic acid does.
What is fulvic acid, and why does a percentage need a definition?
Fulvic acid is the name of a fraction, not of one compound with one formula. Humic substances are split by solubility into humic acid, fulvic acid and humin. A 2007 paper in the Annals of Environmental Science notes that humic acid precipitates below pH 2, while fulvic acid stays in solution at every pH.
A 2025 review by Kamgar and colleagues reports that humic substances make up more than 80% of shilajit by weight, with many differences between regions, and says its chemical composition is not known with certainty. A fulvic acid percentage therefore describes one fraction of a variable mixture.
How do shilajit labels state a fulvic acid figure?
Often they do not: ConsumerLab's September 2024 news item says amounts of fulvic acid are typically not listed on labels. Where a figure is given, it varies widely. In our count of the US National Institutes of Health Dietary Supplement Label Database on 10 October 2026, 21 of the 108 records returned for shilajit attach a fulvic acid percentage to it, from 1% to 70%, in phrases such as "standardized to" and "greater than". None names a measurement method, and the count describes database records, not the whole market.
| Wording of this kind | What it may refer to | Question to ask |
|---|---|---|
| "50% fulvic acid" | The resin as sold, its dry matter, or an extract made from it | Percent of what, and at what water content? |
| "100 mg fulvic acid per serving" | One serving as printed, measured or calculated | How big is the serving in mg, and was the figure measured? |
| "Standardised to at least 50%" | A target or minimum for the material | Is there a measured result for the lot you hold? |
The arithmetic: percentage times serving gives milligrams
Fulvic acid per serving, in mg, is the serving weight in mg times the percentage, divided by 100. The figures below are invented round numbers, used for the arithmetic only. They are not a recommendation and not a statement about any product we sell.
| Invented label | Serving printed | Working | Fulvic acid per serving |
|---|---|---|---|
| 10% | 200 mg | 200 × 10 ÷ 100 | 20 mg |
| 50% | 200 mg | 200 × 50 ÷ 100 | 100 mg |
| 50% | 500 mg | 500 × 50 ÷ 100 | 250 mg |
The same serving gives 20 mg or 100 mg depending on the percentage, and the same 50% gives 100 mg or 250 mg depending on the serving. To go the other way, divide: 100 mg in a 400 mg serving is 100 ÷ 400 × 100 = 25%.
If a page gives both a percentage and an amount, check that they agree: an invented label of 60% and 150 mg for a 200 mg serving fails, because 150 ÷ 200 × 100 = 75%.
The basis matters too. Suppose 100 g of resin as sold holds 10 g of water, a round number chosen for the arithmetic and not a measurement of any resin. The dry matter is then 90 g, and 50% of it is 0.5 × 90 = 45 g, which is 45% of the resin as sold. Labels reading 50% and 45% could describe the same material.
The label facts on the product page list our 30 g pot with directions printed on the pot. This page states no fulvic acid percentage for it.
What have published analyses reported?
Of the sources we read, only ConsumerLab reports measured amounts in retail shilajit products, and its full results sit behind a membership wall. The other two are a method paper and a review.
| Source | What it examined | What it reported | Limits |
|---|---|---|---|
| ConsumerLab, news item of 26 September 2024 and review summary | Eight shilajit supplements it bought: capsules and tablets, gummies and resins | 6.9 mg to 2,206 mg per serving; resins far below extracts in capsules and pills. The summary puts purified resins at about 6% to 7% and extracts at about 60% to 80%. | Public text only: no product-by-product results and no method. |
| Kohli and colleagues, 2026 | Shilajit raw material, extract and resin | An HPLC method for markers including fulvic acid, and gravimetric analysis for total fulvic acid. | A method paper. The abstract has no percentages, and two of the four authors list a herbal-products company. |
| Kamgar and colleagues, 2025 | The published literature on shilajit composition | Humic substances above 80% of weight, composition not known with certainty, differences between regions. | A review of other studies, not of retail products. |
The spread is wide: 2,206 ÷ 6.9 is about 320, so the highest figure was roughly 320 times the lowest, and because these are amounts per serving, serving size feeds into the gap as well as the material. None of these figures describes a product we sell.
Why the same word can mean different things
The fraction is defined by the separation, so the number depends on the method. The 2026 chromatography paper reports gravimetric analysis (weighing) for total fulvic acid and, separately, an HPLC method for fulvic acid as one of three markers. The 2007 paper evaluated a light-absorption method that assumes fulvic acids absorb light the same way whatever their source, and said no practical, low-cost method was then available. Its abstract covers commercial humic products and does not mention shilajit.
What a label percentage cannot prove
- Which lot it describes, which method produced it, or when it was measured.
- Anything else about the material, such as metals: see our guide to what reports say about shilajit and heavy metals.
- What fulvic acid does. This page makes no claim about that.
- That the number is right. ConsumerLab reported one product with far more fulvic acid than its label led it to expect.
What regulators say about fulvic acid wording
Two public bodies have said something about the words themselves. Neither statement is about our pot.
- The European Commission's Novel Food Status Catalogue lists fulvic acid, described as an organic acid isolated from humus, as a novel food that is not yet authorised (entry POL-NF-00369, last modified 16 October 2023). It lists non-isolated fulvic acid the same way, reporting the conclusion of the Lithuanian competent authorities (entry POL-NF-11602, 4 November 2024).
- CVUA Stuttgart, a state food-control laboratory in Baden-Württemberg, said in a report of 29 April 2026 that a "rich in" claim may only refer to nutrients such as vitamins or minerals, so "rich in fulvic acids" is not permitted. The report is in German and the English wording is our translation.
The Commission calls the catalogue non-binding and says EU countries may restrict marketing through specific legislation. The two entries do not say what their status means for shilajit as a whole, which has its own entry. Rules differ by country.
A label-reading checklist
- Is a fulvic acid figure stated at all? If not, only the seller can say.
- Percent of what: the resin as sold, its dry matter, or an extract?
- What is the serving in mg, as printed? Multiply to get mg per serving.
- If a percentage and an amount both appear, do they agree once you divide?
- If a report is offered, which lot, method, date and laboratory does it name?
Our guide to what shilajit resin is and how to read the label covers the rest of the label line by line, and the shilajit resin buying guide puts the checks into one list.
What this page says about our pot
The 30 g Himalayan shilajit resin pot is a food supplement for adults, with directions printed on the pot. Anyone pregnant, breastfeeding or taking medication should consult a doctor first. This page states no fulvic acid figure for it, so there is nothing here to multiply. For other questions see our FAQ.
Questions people ask
How much fulvic acid is in shilajit?
It varies with the product. ConsumerLab's 2024 purchase of eight products found 6.9 mg to 2,206 mg per serving, its summary puts purified resins at about 6% to 7% and extracts at about 60% to 80%, and label claims in a US database run from 1% to 70%. None describes a product we sell.
What fulvic acid percentage is good in shilajit?
This page does not call any percentage good or bad. A higher percentage only means a larger share was counted as fulvic acid by that method, and two percentages compare only if they share a basis.
How do I calculate fulvic acid per serving?
Multiply the serving weight in mg by the percentage and divide by 100. For an invented label of 20% and a 250 mg serving, that is 250 × 20 ÷ 100 = 50 mg.
Does Satiovex state a fulvic acid figure for its shilajit resin?
No. This page states no fulvic acid figure for Satiovex Himalayan Shilajit Resin. Follow what is printed on your pot.
How we checked this page
- Sources opened. On 10 October 2026 we read the two ConsumerLab public pages, the 2007 abstract page, the PubMed abstracts for the 2025 and 2026 papers, the Commission's catalogue and CVUA Stuttgart's German report. We re-ran the label-database search and counted the records ourselves.
- What we could not find. ConsumerLab's full review is behind a membership wall. We read only the 2026 paper's abstract. We did not open pharmacopoeia monographs, so we cannot say whether one sets a method for fulvic acid.
- Review. No doctor, pharmacist or chemist has reviewed this page. It is general information, not medical advice.
- Who we are. Satiovex products are sold by Xinop LLC, trading as Satiovex. We run this site and have a financial interest in the products.
- Testing. This page does not claim independent testing for any product we sell.
- Corrections. If something here is wrong, contact us and we will check it.
