What is this mysterious substance? The name may sound unusual, but shilajit — also known as mumio, moomiyo, or "mountain tar" — is simply a thick, sticky fluid that resembles tar in consistency. Its colour ranges from deep black to white, though most commonly it appears dark brown. Formed over centuries through the slow decomposition of plant matter and minerals in high mountain ranges, shilajit has been used in Ayurvedic medicine for over 5,000 years. Modern science is only now beginning to understand what traditional healers have long known.
What Is Shilajit and Where Does It Come From?
Shilajit is a resin-like substance found between rocks in high-altitude mountain ranges, primarily the Himalayas between India and Nepal. It forms through the gradual decomposition of plant material — including mosses, lichens, and algae — combined with mineral matter, shaped by local temperature, pressure, humidity, and geological conditions over hundreds of years. The word shilajit comes from Sanskrit and translates roughly as "mountain tar" or "conqueror of mountains."
Interestingly, researchers have confirmed that the molecular composition of shilajit varies depending on its geographic origin. This means the specific benefits may differ slightly between samples collected from the Himalayas, the Altai Mountains, or the Caucasus region. Regardless of origin, the core active compounds remain consistent.
Key Compounds in Shilajit
Shilajit's composition is remarkably complex. Humic substances make up 60% to 80% of the total content — these are organic compounds found naturally in soil, water, and fossil fuels. Among the most important bioactive components are:
- Fulvic acids — the primary active compound, known for strong antioxidant activity, tissue regeneration support, and enzyme production
- Ellagic acid — may support immune function and exhibits anti-inflammatory properties
- Amino acids — building blocks of protein that also contribute to neurotransmitter and hormone synthesis
- Polyphenols — powerful antioxidants associated with cardiovascular support
- Triterpenes and sterols — organic compounds with diverse biological activity, involved in lipid transport
- Phenolic lipids — may help inhibit the growth of bacteria, fungi, and parasites
Scientific reports also indicate that shilajit contains B vitamins, provitamin D, and approximately 84 different minerals including calcium, phosphorus, and selenium. This extraordinary mineral density helps explain why shilajit has been valued across so many cultures and centuries.
[tip:Fulvic acid — the primary active compound in shilajit — is highly bioavailable, meaning it's efficiently absorbed from the digestive tract. However, it's also rapidly eliminated, which is why consistent daily supplementation is recommended.]What Does Science Say About Shilajit?
While shilajit enjoys enormous popularity in traditional and natural medicine, scientific research on its effects is still developing. That said, several studies have produced promising results worth noting.
Cognitive Function and Neuroprotection
A 2012 research report suggested that shilajit may help slow the progression of neurodegenerative conditions and contribute to maintaining cognitive function. This effect is largely attributed to fulvic acid's antioxidant capacity, which helps protect cells against free radical damage. For those interested in supporting brain and cognitive health, shilajit represents a fascinating natural option rooted in centuries of traditional use.
Energy and Mitochondrial Function
Research has confirmed that shilajit may influence mitochondrial function — the energy-producing centres of cells. This could translate to increased energy levels, even in cases of chronic fatigue syndrome (CFS), a condition characterised by extreme exhaustion that cannot be explained by an underlying illness. For anyone seeking natural energy support, shilajit's effect on cellular metabolism makes it a compelling choice.
Men's Health and Testosterone
Shilajit has shown particular relevance for men's health. Clinical studies have indicated that regular supplementation may support healthy testosterone levels — the primary male sex hormone. Additionally, a 2010 trial found that three months of shilajit use was associated with improvements in total sperm count, sperm motility, and overall semen quality.
Iron Metabolism and Cellular Health
Scientists also believe that shilajit supplements may gradually support healthy iron levels in the body and promote cellular metabolism. The full potential of this substance remains to be explored, and further research is certainly needed to understand exactly how shilajit works at the molecular level.

Shilajit is widely used in Ayurvedic medicine, but there are no official dosage guidelines for the substance. Fulvic acid is highly bioavailable — it absorbs well from the digestive tract — but is also eliminated relatively quickly from the body. In published studies, dosages varied depending on the intended purpose.
Healthcare professionals generally recommend that appropriate dosing depends on several factors, including age, overall health status, and desired outcomes. The safest approach is to follow the dosage indicated on a quality supplement product and to consult a healthcare provider if you have specific health concerns. Shilajit is available in several forms — capsules, resin, and powder — each offering different concentrations and methods of use.
Contraindications and Safety
Shilajit is generally considered safe when taken as a properly processed supplement. Raw, unprocessed shilajit should never be consumed, as it may contain heavy metals, free radicals, or other potentially harmful substances. Always choose products from reputable manufacturers that undergo proper purification.
Certain conditions require medical consultation before using shilajit:
- Sickle cell anaemia
- Haemochromatosis — a condition involving excessive iron absorption
- Thalassaemia — a group of inherited blood disorders affecting haemoglobin production
Shilajit may increase uric acid production, which could negatively affect conditions such as gout, kidney stones, hypothyroidism, and haemolytic anaemia. It should not be used in any form by pregnant or breastfeeding women, infants, or young children. Among potential side effects, a decrease in blood pressure is the most commonly noted — while often desirable, this can be problematic for individuals with diagnosed hypotension or certain heart conditions.
[warning:Always consult a healthcare professional before starting shilajit supplementation, especially if you have pre-existing health conditions or are taking medication. Never consume raw, unprocessed shilajit.]Key Takeaway: Shilajit is a powerful natural substance with a history stretching back millennia in Ayurvedic tradition. Rich in fulvic acids, minerals, and bioactive compounds, it may support cognitive function, energy levels, and men's health. While research continues to uncover its full potential, quality-processed shilajit supplements offer a safe and accessible way to explore the benefits of this ancient Himalayan substance.
