What Is Shilajit?

In short: Shilajit is a dark, tar-like resin that forms over centuries from compressed organic plant matter in high-altitude mountain rocks, primarily in the Himalayas. Its primary active compound is fulvic acid, which supports energy, mineral absorption, and cellular health. It has been used in Ayurvedic medicine for over 3,000 years and is now sold globally as a purified food supplement.

What Shilajit Is

Shilajit is a natural phytocomplex — a complex mixture of organic and mineral compounds — that seeps from rock crevices in high-altitude mountain ranges during warmer months. It is most commonly found in the Himalayas, Altai, Caucasus, and Tibetan Plateau, typically at altitudes between 1,000 and 5,000 metres.

In its raw form, Shilajit is a dark brown to black, sticky resin with a characteristic earthy smell. It must be purified before use to remove contaminants including heavy metals, mycotoxins, and free radicals that can be present in unprocessed material. High-quality Shilajit supplements are independently lab-tested to verify both purity and active compound content. See: how to verify Shilajit authenticity.

How Shilajit Forms

Shilajit forms over hundreds to thousands of years through the slow decomposition of plant matter — primarily mosses, lichens, and other high-altitude vegetation — compressed between layers of rock. Microbial action, pressure, and temperature changes over geological timescales transform this organic material into the humic substance complex we know as Shilajit. See: Shilajit: what it is and a brief history.

What Shilajit Contains

The primary active compound in Shilajit is fulvic acid, which typically comprises 60–80% of a high-quality purified preparation. Shilajit also contains humic acid, dibenzo-α-pyrones, over 84 trace minerals in ionic form, and amino acids. See: Shilajit and fulvic acid: what's the connection? and what minerals are in Shilajit?

At 5 Rivers Nutrition, our Shilajit Gold+ products contain 76.74–79.22% fulvic acid — confirmed by Eurofins independent laboratory testing. View our lab certificates.

History and Traditional Use

Shilajit has been used in Ayurvedic medicine for over 3,000 years, classified as a rasayana — a rejuvenating tonic for longevity, vitality, and resilience. It is known as mumijo in Russian medicine, salajeet in Urdu, and shargai in Mongolian.

Modern Science and Research

Key research areas include mitochondrial function (Bhattacharyya et al., 2009), testosterone support (Pandit et al., 2016), neuroprotection (Guzmán-Martínez et al., 2012), and mineral bioavailability (Rybicka et al., 2019). See: does Shilajit really work or is it just hype?

Forms of Shilajit

Shilajit is available as resin (traditional, minimally processed), capsules (convenient, pre-measured), or powder. The most important factor is the fulvic acid concentration and independent third-party lab testing. See: Shilajit capsules vs. resin: which should you buy?

Frequently Asked Questions

What exactly is Shilajit made of?

Decomposed organic plant matter compressed between mountain rocks over centuries. Primary active compound is fulvic acid (60–80%), along with humic acid, dibenzo-α-pyrones, and over 84 trace minerals.

Is Shilajit a drug or a supplement?

In the UK, Shilajit is sold as a food supplement, not a drug. It is legal to buy and sell when properly labelled and compliant with food safety regulations. See: is Shilajit regulated in the UK?

Where does the best Shilajit come from?

Himalayan Shilajit is widely considered highest quality. However, independent lab testing of fulvic acid content and heavy metal safety is the only reliable quality indicator.

Is Shilajit the same as fulvic acid?

No. Fulvic acid is the primary active compound within Shilajit, but Shilajit also contains humic acid, dibenzo-α-pyrones, trace minerals, and other bioactive compounds.
