Shilajit is one of those substances that sounds too strange to be real. A tar-like resin that oozes from mountain rocks, formed over centuries from decomposing plant matter, packed with minerals and organic compounds. It has been used in Ayurvedic medicine for thousands of years, and it is now showing up in supplement aisles across the Western world.
But what is shilajit, and why are so many people paying attention to it?
The answer starts in the mountains, moves through a surprisingly complex chemical profile, and lands in a growing body of modern research. Scientific support is beginning to catch up with centuries of traditional use.
Where Does Shilajit Come From?
Shilajit forms at high altitudes, typically between 1,000 and 5,000 meters above sea level. You can find it seeping from rock crevices in the Himalayas, the Altai Mountains, the Caucasus range, and parts of Central Asia and South America. The substance appears as a dark, sticky exudate; blackish-brown in color with a consistency somewhere between tar and soft wax.
The formation process of pure Himalayan shilajit resin spans centuries. Plant species like Euphorbia royleana and Trifolium repens decompose under the influence of microbial activity and temperature shifts between rock layers. Over time, this process creates a dense, mineral-rich substance. During the warmer months, the shilajit substance oozes from cracks in mountain stones.
The composition of shilajit varies depending on the geographic region, the plant life in that area, and local environmental conditions. Himalayan shilajit, for example, differs from Altai Mountain shilajit in its molecular profile, even though both share similar physical properties.
In Sanskrit, “shilajit” roughly translates to “conqueror of mountains” or “rock tar.” Other names for it include mumie, mumijo, mineral pitch, and salajit. Communities across Nepal and India to Tibet and Central Asia have used it for generations as a general tonic, mixing it with warm milk or water.

What Is Shilajit Made Of?
The composition of shilajit is complex. It is not a single compound but a phytocomplex, meaning it contains a wide range of organic and inorganic substances working together. The primary components include humic substances, which account for roughly 60 to 80 percent of shilajit’s total composition.
Fulvic Acid
Fulvic acid is the most studied and most discussed component of shilajit. It is a small, water-soluble organic molecule that forms during the decomposition of plant matter in soil and rock.
What makes fulvic acid notable is its ability to bind (chelate) minerals like magnesium and iron, then carry them across cell membranes. Because of its low molecular weight, fulvic acid is absorbed in the intestinal tract and moves through the body with relative ease.
Genuine Himalayan shilajit typically contains between 5 and 20 percent fulvic acid, depending on the source and purification method. Some supplement brands claim much higher percentages, but lab analyses suggest that products advertising 50 percent or more fulvic acid content may contain synthetic additions or may not be authentic shilajit.
Humic Acid and Humins
Beyond fulvic acid, shilajit contains humic acid and humins. Humic acid is similar to fulvic acid but has a higher molecular weight and is only soluble in alkaline conditions. Humins are not water-soluble at all. Together, these humic substances form the structural backbone of shilajit and may contribute to nutrient absorption and gut health.
Minerals and Trace Elements
Shilajit contains over 80 minerals in ionic form, including calcium and magnesium alongside iron and zinc, with other trace elements varying by source. The mineral content typically makes up 15 to 20 percent of shilajit’s total composition, with the exact profile varying by source region. These minerals may support a range of bodily functions, from hormone regulation and bone maintenance to enzyme activity and muscle function.
Other Bioactive Compounds
The compound profile extends further. Shilajit contains dibenzo-alpha-pyrones (DBPs), which have been associated with antioxidant activity and mitochondrial support. You will also find amino acids and fatty acids, polyphenols, and sterols in varying quantities.

How Does Shilajit Work in the Body?
Understanding shilajit’s mechanisms – and the benefits of shilajit – requires looking at several pathways, because the substance does not operate through a single action.
Mitochondrial Support and Energy Production
One of the most researched areas involves shilajit’s relationship with mitochondria. Mitochondria are the energy-producing structures inside your cells. They convert nutrients into adenosine triphosphate (ATP), which your body uses as fuel. The dibenzo-alpha-pyrones in shilajit, along with fulvic acid, may help protect mitochondria from oxidative damage and support more efficient ATP production. Animal studies have shown that shilajit supplementation was associated with higher post-exercise ATP concentrations in muscle tissue compared to controls.
Antioxidant Activity
Fulvic acid acts as a free radical scavenger. Free radicals are unstable molecules that can damage cells over time, contributing to aging and various health concerns. Research on shilajit’s antioxidant capacity has produced promising results in laboratory settings, with some analyses showing an ORAC (Oxygen Radical Absorbance Capacity) index higher than commonly cited antioxidant foods. Whether these lab results translate directly to human benefit is still being studied.
Nutrient Transport and Bioavailability
Fulvic acid’s chelating properties mean it may help your body absorb and use minerals more effectively. Think of it as a delivery system. Fulvic acid binds to minerals and, because of its small size and water solubility, carries them across intestinal walls and into cells. This is one reason shilajit has been valued in traditional medicine as a complement to other supplements and foods.

Hormonal Support
A randomized, placebo-controlled study published in Andrologia found that men aged 45 to 55 who took 250 mg of purified shilajit twice daily for 90 days showed increases in total and free testosterone compared to the placebo group. While promising, this area of research is still young. Most human studies have been small and short-term, and several have been industry-funded. More independent, long-term research is needed before drawing firm conclusions.
How People Take Shilajit
Shilajit is available in several forms, each with trade-offs worth understanding.
Resin
Shilajit Resin is considered the most traditional way to take shilajit. This sticky, dark substance is dissolved into warm water, milk, or tea to consume. Resin typically contains the full spectrum of compounds in their original ratios. The downsides: an earthy, bitter taste and the need to measure each dose manually.

Capsules
If the traditional use of resins isn’t your “cup of tea”, Shilajit Capsules offer convenience and pre-measured dosing without the taste factor. They are easy to travel with and fit into any routine. Just take with water or juice. See our guide to Shilajit Resin vs Powder vs Capsule.
Gummies
Shilajit Gummies taste good, require no preparation, and make supplementation effortless. While the most palatable shilajit form, gummies may have added sweeteners and flavoring, and/or less active shilajit per serving. Buy lab-tested gummies from reputable brands, and check the labels for potency + quality ingredients.
Liquid Drops
Drops are versatile. You can add them to water, tea, smoothies, or other beverages. Dosing is flexible, and absorption may be faster than capsules or gummies.
Shilajit Dosing
Most shilajit studies have used daily doses in the range of 200 to 500 mg, though some research has used doses up to 2 grams per day for shorter periods. While there is no industry standard on dosing, common recommended dosing for processed shilajit is up to 500 mg daily.
As with other botanicals, begin with a lower dose than the label recommends, and listen to your body as you make the appropriate adjustments to your routine. See our detailed user guide: How Much Shilajit To Take Per Day
What to Look for in a Quality Shilajit Product
Not all shilajit products are equal. The substance requires processing to remove impurities, including potential heavy metals like lead, arsenic, and mercury that can be present in raw mountain material.
When evaluating a shilajit product, consider these factors:
- Third-party lab testing for purity and heavy metal content
- Transparent ingredient sourcing with clear origin information
- Appropriate fulvic acid percentages (authentic shilajit typically falls in the 5 to 20 percent range)
- GMP-compliant manufacturing processes
- Certificate of Analysis lab test reports
Raw, unprocessed shilajit should be avoided, as it may contain higher levels of thallium and other heavy metals.

Safety Considerations
Processed shilajit appears to be well-tolerated in most adults when taken within recommended dosages. Common shilajit side effects, when they occur, tend to be mild digestive discomfort.
Important Safety Information: Shilajit may lower blood sugar levels and could interact with diabetes medications. If you are scheduled for surgery, discontinue use at least two weeks beforehand. Pregnant and breastfeeding women should avoid shilajit, as safety data for these populations is insufficient. Always consult your healthcare provider before adding shilajit to your routine, especially if you take prescription medications.
