What Exactly is Shilajit?
Shilajit is a sticky, tar-like substance that seeps from rocks in high mountainous regions, most notably the Himalayas. It is formed over centuries from the slow decomposition of plant matter and is a complex mixture of organic compounds and minerals. The therapeutic properties associated with shilajit are largely attributed to its high concentration of humic substances, particularly fulvic acid. Fulvic acid is a powerful antioxidant that helps protect cells from damage caused by oxidative stress.
The Science Behind Shilajit's Reported Benefits
While many claims surrounding shilajit are based on centuries of traditional use, a growing body of preliminary research suggests several potential benefits. It is important to note that many of these studies are small-scale or conducted on animals, so more extensive human trials are needed to confirm the effects conclusively.
- Enhances Energy and Reduces Fatigue: Some studies suggest shilajit can improve mitochondrial function, helping the body's cells produce more energy. In a 2012 study, rats with chronic fatigue syndrome (CFS) showed a reduction in symptoms after receiving shilajit, believed to be linked to its effects on mitochondrial function. This mechanism could translate to improved stamina and reduced fatigue in humans.
- Supports Male Fertility and Testosterone Levels: Several studies have shown a potential link between purified shilajit supplementation and increased male fertility. A clinical trial found that infertile men who took shilajit for 90 days had significant increases in total sperm count and sperm motility. Another study on healthy volunteers observed a significant increase in total testosterone levels after 90 days of purified shilajit supplementation.
- Promotes Cognitive and Brain Health: The fulvic acid in shilajit has shown promising neuroprotective properties. Research suggests it may help prevent the abnormal buildup of tau protein, a key factor in the progression of Alzheimer's disease. By stopping this protein aggregation and reducing inflammation in the brain, shilajit could help improve memory and cognitive function.
- Aids in Anti-Aging and Longevity: As a potent antioxidant, shilajit is believed to protect the body against free radicals and cellular damage, which contribute to the aging process. Some proponents suggest that its regular use could promote longevity and better overall health, a concept rooted in its traditional Ayurvedic classification as a 'rasayana,' or rejuvenating substance.
- Improves Bone Health: A 2022 randomized, double-blind, placebo-controlled trial found that daily shilajit supplementation improved bone mineral density in postmenopausal women with osteopenia. The minerals, including magnesium and calcium, likely contribute to this effect.
- Helps with Iron Deficiency Anemia: Shilajit is a good source of iron, and one study in rats showed that it helped to increase hemoglobin, hematocrit, and red blood cell levels. This suggests a potential role in managing iron deficiency anemia, though more human research is needed.
- Reduces Stress and Anxiety: As an adaptogen, shilajit can help the body adapt to stressful situations and lower cortisol levels. While many studies on this are in animals, preliminary evidence suggests it may have a calming effect and reduce symptoms of anxiety.
Comparing Shilajit with Other Supplements

Important Safety and Purity Considerations
Due to a lack of regulation by bodies like the FDA, the market is filled with varying quality shilajit products, some of which may be contaminated. Raw or unprocessed shilajit may contain heavy metals, fungus, and other impurities that can be harmful. It is crucial to choose a purified product from a reputable source and look for evidence of third-party testing.
Potential Side Effects and Contraindications
While purified shilajit is generally considered safe when taken as directed, certain individuals should exercise caution or avoid it entirely. Side effects can include dizziness, upset stomach, or, rarely, allergic reactions.
- Low Blood Pressure: Shilajit may lower blood pressure, posing a risk for individuals with hypotension or those on blood pressure medication.
- Diabetes: It might lower blood sugar levels and interfere with glucose control, especially in those with diabetes.
- High Iron Conditions: Individuals with hemochromatosis or other iron overload disorders should not take shilajit, as it can increase iron levels.
- Pregnancy and Breastfeeding: Due to insufficient safety research, it is best to avoid use during pregnancy or while breastfeeding.
Conclusion: The Final Verdict on Shilajit's Benefits
Shilajit, a substance long cherished in Ayurvedic medicine, is backed by some promising modern scientific research, particularly regarding its ability to boost energy, improve male fertility, and support cognitive function. Its rich fulvic acid content, responsible for its antioxidant and anti-inflammatory properties, is a key driver of these potential benefits. However, much of the human research remains small-scale, and larger, more rigorous trials are needed for definitive conclusions. For those interested, exercising caution by choosing a reputable, purified, and third-party tested product is essential to ensure safety. As with any new supplement, consulting a healthcare provider is recommended, especially for individuals with pre-existing health conditions or those taking other medications. While not a magic bullet, shilajit holds potential as a complementary wellness booster for specific concerns when sourced and used responsibly.
