Shilajit
TL;DR
Ancient mineral-rich substance from Himalayan rocks used in Ayurveda
Contains fulvic acid and trace minerals that may support cellular energy
Limited but promising research on testosterone and sperm quality
May enhance mitochondrial function and reduce fatigue
Quality varies dramatically - heavy metal contamination is a major concern
Best for: Energy support, male reproductive health (choose purified sources only)
What it is
Shilajit is a sticky, tar-like substance that oozes from rocks in high mountain ranges, particularly the Himalayas, formed over centuries from the decomposition of plant matter. In Ayurvedic medicine, it's considered a powerful rasayana (rejuvenative) and has been used for thousands of years to enhance vitality and longevity.
The primary active component is fulvic acid (15-20%), along with over 80 trace minerals in ionic form. Fulvic acid is a powerful organic compound that can enhance cellular energy production and nutrient absorption. Traditional preparation involves purification to remove toxins and heavy metals, though modern processing methods vary dramatically in quality and effectiveness.
Shilajit has gained massive popularity in biohacking and men's health communities, partly due to its traditional reputation as a male tonic and emerging research on testosterone and mitochondrial function.

Safety
The safety of shilajit depends entirely on proper purification. Raw or poorly processed shilajit can contain dangerous levels of heavy metals (lead, mercury, arsenic), free radicals, and other toxins that can cause serious health problems. Reputable manufacturers use standardized purification processes to remove these contaminants.
Properly purified shilajit is generally well-tolerated, though some people experience digestive upset, particularly when starting supplementation. The high mineral content can cause nausea if taken on an empty stomach. People with hemochromatosis (iron overload) should avoid shilajit due to its iron content, and those with autoimmune conditions should use caution as it may stimulate immune function.
Interactions
• Iron supplements - May enhance iron absorption, potentially leading to overload (monitor iron levels) • Diabetes medications - Could affect blood sugar levels (monitor glucose) • Blood thinners - Limited data, but fulvic acid may theoretically affect clotting (mild concern) • Immunosuppressants - May stimulate immune function, potentially interfering with therapy (theoretical) • Heavy metal chelation therapy - Could interfere with treatment (avoid combination)
Dosing
Standard Dosing: 300-500 mg of purified shilajit daily
Resin Form: Pea-sized amount (200-300 mg) dissolved in warm water or milk
Powder/Capsules: 250-500 mg daily with food
Timing: Best taken in morning or early afternoon to avoid potential sleep interference
Start with lower doses to assess tolerance. Take with food to minimize digestive upset. Cycling (6-8 weeks on, 2 weeks off) is sometimes recommended, though not required. Always choose products with certificates of analysis showing heavy metal testing.
Cost
Quality purified shilajit resin typically costs $35-60 per month, reflecting the expense of proper sourcing and purification. Cheaper powders and capsules ($15-25/month) are often of questionable quality or purity. Premium brands with extensive testing and traditional processing methods can cost $50-80 monthly.
Given the potential for contamination with cheap products, investing in higher-quality options is essential for safety. The cost reflects both the rarity of authentic shilajit and the expense of proper purification processes.
The bottom line
Shilajit has intriguing traditional uses and emerging research support, particularly for male reproductive health and energy. However, the supplement market is flooded with low-quality products that may contain dangerous contaminants. Those interested should invest in properly purified products from reputable manufacturers with third-party testing. While promising, the limited human research and quality concerns make it more of an experimental supplement than a proven necessity.
