Mineral pitch - better known by its Sanskrit name, shilajit - is a sticky, tar-like resin that oozes from rock crevices in the Himalayas, the Altai Mountains, and a handful of other high-altitude ranges. It forms over centuries as plant matter breaks down under pressure, mixing with minerals from the surrounding rock. In Ayurvedic medicine, it’s classified as a rasayana, a substance believed to support vitality and slow aging.
The supplement market has caught up with the tradition. You’ll now find mineral pitch as resin, powder, and capsules, marketed for energy, testosterone, cognitive function, and general anti-aging. But the honest picture is more nuanced than most product pages let on: some effects have real clinical backing, others are still speculative, and purity is a genuine concern that gets less attention than the benefits do.
What’s Actually in Mineral Pitch
The therapeutic interest in shilajit centers on a few key components:
- Fulvic acid — the dominant bioactive compound, believed to act as an antioxidant and to help transport minerals into cells.
- Humic acid — a related organic compound with antioxidant properties
- Dibenzo-α-pyrones — a class of metabolites studied for antioxidant and antimicrobial activity
- Trace minerals — commercial products list anywhere from a dozen to over 80, including iron, zinc, copper, magnesium, and selenium, depending on the source rock
The mineral content varies significantly by region and processing method, which is part of why research findings are hard to generalize across brands.
What the Research Actually Supports
It’s worth being direct about the state of the evidence: human clinical trials on shilajit are limited in number and generally of low methodological quality. Preliminary human research has found some positive effects, but these are typically based on just one or two trials that need confirmation from larger, higher-quality studies. With that caveat in place, here’s where the evidence is strongest to weakest.
Testosterone and hormonal markers. This is the most studied benefit. In a notable trial, men who took 250 mg of purified shilajit twice daily for 90 days showed statistically significant increases in total testosterone, free testosterone, and DHEAS compared to a placebo group. A 2024 systematic review similarly found that a purified, standardized shilajit extract may help raise testosterone in men with late-onset hypogonadism.
Antioxidant and anti-inflammatory activity. Scientific literature and ethnopharmacological research suggest shilajit has anti-stress, memory- and energy-enhancing, antioxidant, anti-inflammatory, antidiabetic, neuroprotective, anti-ulcer, and wound-healing activity — but much of this comes from lab and animal studies rather than large human trials.
High-altitude adaptation. Traditional use includes managing altitude sickness symptoms like fatigue and low oxygen tolerance, attributed to shilajit’s mineral density and antioxidant activity, though this is based more on traditional use than controlled human trials.
Cognitive function and anti-aging. These are the most heavily marketed but least substantiated claims. Fulvic acid’s antioxidant activity has led to speculation about its potential to protect against cognitive decline, but a broader research gap remains: there is a lack of evidence that shilajit is bioactive in the way many products claim, and its immunomodulatory effects, specifically, still lack strong scientific validation.
If a product page promises it will reverse aging, cure a disease, or replace medication, treat that as a marketing claim, not a clinical one.
The Risk That Matters More Than Most Reviews Mention: Contamination
This is the part of the mineral pitch conversation that gets buried under benefit lists. Shilajit forms in mineral-rich rock, which means the same geology that gives it its nutrient profile can also concentrate heavy metals — lead, arsenic, mercury, and cadmium being the primary concerns, with newer research also flagging thallium in some regional sources.
A few things worth knowing before buying:
Concern Why it happens What reduces the risk
Heavy metal contamination Metals in surrounding rock leach into raw resin during formation Third-party heavy metal testing, certificate of analysis
Microbial contamination Raw resin collected from rock faces carries bacteria and mold Proper purification (filtration, purification, dehydration steps)
Inconsistent potency Fulvic acid and mineral content vary widely by source Standardized extracts with disclosed fulvic acid percentage.
Adulteration Unregulated market allows fillers or synthetic substitutes GMP-certified manufacturers, reputable brands.
One 91-day animal safety study found no organ damage even at high doses — but only when the shilajit used was properly purified. Unpurified or poorly sourced resin is a different story, and independent testing has documented that some Ayurvedic supplement products, shilajit included, contain harmful levels of heavy metals. Regulatory bodies, including Health Canada, have issued warnings about heavy metal contamination in unapproved Ayurvedic products specifically.
The practical takeaway: raw or unpurified shilajit scraped from rock is not something to consume as-is. If you’re going to try it, that means a purified, lab-tested product with a certificate of analysis — not the cheapest resin you can find online.
Who Should Be Cautious
A few groups have specific reasons to talk to a doctor before adding mineral pitch to a daily routine:
- People with hemochromatosis or high ferritin — shilajit’s iron content can worsen iron overload
- Anyone on blood sugar medication — shilajit may lower blood glucose, which can compound the effect of diabetes medications
- People with heart conditions or on heart medication — potential interactions haven’t been well studied
- Pregnant or breastfeeding individuals — there isn’t enough safety data to recommend use
- Anyone with kidney or liver disease — reduced ability to clear any contaminants that are present
How People Typically Take It
Purified shilajit resin is usually dissolved in warm water or milk rather than eaten directly — a pea-sized amount (roughly 300–500 mg) is a common starting dose, though label directions vary by product concentration. Capsule products list dosage on the label, generally in the 250–500 mg range per serving. There’s no established “daily requirement” the way there is for a vitamin — this is a supplement with a traditional use pattern, not a clinically defined dosing protocol.
A Practical Way to Evaluate a Product
Before buying, check for:
- A certificate of analysis (COA) from third-party testing showing heavy metal levels
- Disclosed fulvic acid percentage
- GMP certification of the manufacturing facility
- Clear sourcing information (region of origin)
- No claims to treat, cure, or prevent a specific disease — that’s a regulatory red flag, not a good sign.
FAQ
Is mineral pitch the same as shilajit?
Yes. “Mineral pitch” is a common English name for shilajit, sometimes also called mumijo or salajeet depending on the region.
Is it safe to take mineral pitch every day?
Purified, third-party tested shilajit appears to be well tolerated in the doses used in clinical studies. Unpurified or untested resin carries real contamination risk and shouldn’t be taken at all.
What does mineral pitch do for testosterone?
The best available clinical evidence shows purified shilajit taken twice daily over 90 days raised total and free testosterone in healthy men compared to placebo. This is one of the more well-supported benefits, though still based on a small number of trials.
Can mineral pitch help with energy and fatigue?
This is a common traditional use, attributed to its mineral density and antioxidant compounds, but large controlled human trials do not back it.
What are the biggest risks of taking shilajit?
Heavy metal and microbial contamination from unpurified or poorly regulated products is the primary risk, followed by potential interactions for people with iron overload conditions, diabetes, or heart disease.
How do I know if a shilajit product is actually pure?
Look for a certificate of analysis from independent lab testing, GMP certification, and disclosed sourcing — not just marketing language like “100% pure Himalayan.”
Does mineral pitch interact with medication?
It may interact with diabetes medication (due to blood sugar effects) and iron supplements. Anyone on prescription medication should check with a doctor first.
