What Is Fulvic Acid?
Fulvic acid is the water-soluble fraction of humic substances. What it is, how it is measured, why it carries minerals, and where the evidence stops.

Fulvic acid guides
What fulvic acid is, in plain language.
Guides
The guides are the definitional layer of the fulvic acid topic, in plain language. Fulvic acid is defined by a solubility test rather than a formula: it is the fraction of humic substances that stays dissolved at every pH, while humic acid precipitates in strong acid and humin never dissolves at all. That one fact explains why it binds minerals, why it ends up on shilajit labels, and why two laboratories can report different percentages for the same jar.
What is fulvic acid is the whole definition: the chemistry, the three commercial sources, how the percentage is measured, and what has and has not been tested in people. For the label question, what a stated percentage is worth and what to ask a seller, go to fulvic acid benefits. The glossary entries filed here define fulvic acid and humic acid in a sentence each, for readers who want the term rather than the article.

The compound doing most of the work. What soil microbes make out of plant matter over centuries, and why it changes how minerals are absorbed.
The questions everyone asks
What is shilajit, actually?
A dark resin that seeps out of rock at altitude in the Himalaya, made of plant matter pressed and broken down over a very long time. What comes off the rock is not the product. Shodhana, the purification step, is what separates the resin from everything it was sitting in, and that is the step worth asking a seller about.
Why does fulvic acid matter?
Fulvic acid is a carrier molecule. It binds trace minerals and is studied as a way of getting them across a cell membrane, which is why the interesting question about a mineral is not how much is in the jar but how much of it arrives. That is the mechanism the research is built on. It is a line of study, not a settled fact, and nobody should sell it to you as one.
How much do I take, and when would I notice anything?
A rice-grain portion, dissolved in warm water or under the tongue, once a day. A 30g jar lasts two to three months at that dose. Shilajit is not a stimulant and nothing here works like one, so the honest unit of time is a month rather than an afternoon. If you want the caffeine experience this will disappoint you.
Resin or capsules?
The range includes resin and six distinct capsule formulas in vegan HPMC shells. Ingredient amounts are listed for each product rather than reduced to one formula for the whole range. One caution: the Sea Moss and Bladderwrack blend contains iodine, so if you have Hashimoto’s or any diagnosed thyroid condition, take that one to your doctor rather than to the checkout.
Where does it come from, and how do I know it is clean?
Our products come from the white-label range offered by established UK supplier Pure Shilajit UK. The supplier describes its resin as Himalayan-sourced. Certificate of Analysis 63849 from Alex Stewart Agriculture, Liverpool (ISO 17025 accredited analyses) covers the February 2026 resin batch: arsenic 0.02, cadmium under 0.2, lead 0.44 and mercury 0.03 mg/kg. It covers the resin only; the capsules are not independently tested.
Do you ship outside Europe?
We ship worldwide, with one exception: not to the United States. Orders to the United Kingdom pay GBP 7.00, free for orders of GBP 140 or more. Switzerland and Europe pay CHF 6.90, free from CHF 150; every other country CHF 14.90, free from CHF 200, converted at checkout.
