Discover the remarkable natural substance that’s been capturing the attention of both traditional healers and modern scientists. Shilajit, a sticky resin exuded from high-altitude rocks in the Himalayas and other mountain ranges, has been used for thousands of years in Ayurvedic medicine. Today, cutting-edge research is validating what ancient practitioners have long known: this unique substance offers a wealth of potential health benefits. Let’s explore what science reveals about this fascinating natural compound.
Shilajit (also known as mumijo, mumie, or moomiyo) is a blackish-brown resinous substance that slowly exudes from layers of rock in mountainous regions, primarily the Himalayas. This tar-like material forms over centuries through the decomposition of plant matter and minerals, creating a complex substance rich in beneficial compounds.
In Sanskrit, “shilajit” translates to “conqueror of mountains” or “destroyer of weakness.” For over 3,000 years, traditional Ayurvedic medicine has revered shilajit as a rejuvenator and adaptogen. Ancient texts describe it as a powerful substance capable of enhancing strength, supporting vitality, and promoting longevity.
Modern analysis reveals shilajit contains over 84 minerals in ionic form, as well as fulvic acid, humic acid, amino acids, and plant-based antioxidants. Its primary bioactive component, fulvic acid, is believed to be responsible for many of its therapeutic properties by helping transport nutrients into deeper tissues and removing toxins.
Recent scientific research has begun to validate traditional claims, with numerous studies examining shilajit’s potential benefits for human health. From enhancing cellular energy production to supporting cognitive function, this ancient substance continues to impress researchers with its wide-ranging effects. Let’s examine what the science reveals about shilajit’s most promising health benefits.

This energy-enhancing effect aligns perfectly with traditional Ayurvedic applications, where shilajit was often prescribed to combat fatigue and boost stamina—particularly among those living in high-altitude regions where oxygen levels are lower and energy conservation is critical.
2. Supports Brain Health and Cognitive Function
Emerging research suggests shilajit may offer significant neuroprotective benefits. Rich in dibenzo-alpha-pyrones and fulvic acid, shilajit appears to help shield brain cells from damage while supporting optimal neural function.
A 2012 study published in the International Journal of Alzheimer’s Disease found that shilajit’s active components may inhibit the aggregation of tau protein—a process implicated in several neurodegenerative conditions. Additional research indicates shilajit may:
- Reduce oxidative stress in brain tissue
- Support memory formation and retention
- Help maintain acetylcholine levels, a neurotransmitter essential for learning
These findings help explain why traditional Ayurvedic practitioners often prescribed shilajit for “mental clarity” and “sharpness of intellect,” suggesting its potential as a natural cognitive supporter particularly relevant in our modern age of increased cognitive demands and longer lifespans.
3. Boosts Testosterone Levels and Male Fertility
Shilajit has demonstrated remarkable effects on male reproductive health. A pioneering clinical study published in Andrologia involved 60 infertile men who received shilajit twice daily for 90 days. The results showed significant increases in:
- Total testosterone levels (by up to 23.5%)
- Free testosterone (the biologically active form)
- Follicle-stimulating hormone (FSH), which supports sperm production
Beyond hormone production, research in the American Journal of Men’s Health found that shilajit supplementation improved several sperm parameters, including:
- Total sperm count (increased by 61.4%)
- Sperm motility (improved by 37.6%)
- Percentage of healthy sperm morphology
These benefits may result from shilajit’s mineral content, antioxidant properties, and ability to enhance cellular energy production—all crucial factors in male reproductive health. For men concerned about fertility or age-related testosterone decline, shilajit represents a scientifically-supported natural option.

- Enhance uptake of fat-soluble vitamins
- Improve cellular utilization of nutrients
This enhanced nutritional delivery system works through several mechanisms, including improved gut barrier function and increased permeability of cell membranes to beneficial compounds. By optimizing nutrient absorption, shilajit helps ensure the body can fully utilize dietary and supplemental nutrients—particularly important for those with compromised digestive function or increased nutritional needs.
7. Supports Immune System Function
Research published in the International Immunopharmacology journal reveals shilajit possesses significant immunomodulatory properties. Rather than simply stimulating or suppressing immune function, shilajit appears to help regulate and balance immune responses.
Clinical and laboratory studies show shilajit can:
- Enhance the activity of natural killer (NK) cells, important for targeting viral infections and cancer cells
- Modulate inflammatory cytokine production
- Support phagocytosis—the process by which immune cells engulf and destroy pathogens
The humic substances in shilajit exhibit antibacterial and antiviral properties, providing additional protection against infections. These immunomodulatory effects align with traditional uses of shilajit for strengthening resilience against disease and maintaining wellness through changing seasons.
8. Helps Manage Blood Sugar Levels
Emerging research suggests shilajit may offer benefits for glucose metabolism and insulin sensitivity. A study in the Journal of Diabetes Research found that shilajit supplementation helps activate PPAR-? (peroxisome proliferator-activated receptor gamma)—a protein that regulates glucose metabolism and improves insulin sensitivity.
Scientific investigations reveal several mechanisms by which shilajit may support healthy blood sugar levels:
- Reducing oxidative stress in pancreatic beta cells, which produce insulin
- Improving cellular glucose uptake
- Modulating enzymes involved in carbohydrate metabolism
While more clinical research is needed, these preliminary findings suggest shilajit may serve as a complementary approach for those concerned about blood sugar management. Researchers note that shilajit’s blood sugar balancing effects appear to be gradual and cumulative, suggesting benefit from consistent long-term use.
9. Provides Adaptogenic Stress Relief
Adaptogens are substances that help the body resist physical, chemical, and biological stressors, and shilajit demonstrates classic adaptogenic properties. Research in the Journal of Ethnopharmacology confirms shilajit can modulate the hypothalamic-pituitary-adrenal (HPA) axis—our body’s primary stress response system.
Studies reveal that regular shilajit consumption may:
- Normalize cortisol levels (the primary stress hormone)
- Support adrenal gland function and resilience
- Reduce anxiety markers in response to stressful stimuli
These adaptogenic effects may be particularly relevant in our modern high-stress environment. Clinical observations suggest shilajit can help the body maintain homeostasis during periods of increased stress, potentially reducing the negative physical and mental impacts of chronic stress exposure.
