Shilajit — a tar-like mineral resin that seeps from rocks in the high Himalayan, Altai and Caucasus mountains — has been used in Ayurvedic medicine for more than 3,000 years. Modern research is now catching up to what traditional healers always knew: this dark, fulvic-acid-rich substance is one of the most bioavailable, mineral-dense natural compounds on the planet.
In this guide we cover what Shilajit actually is, how it works at a cellular level, the evidence behind its most claimed benefits, and how to take it safely. If you already know the science and just want our purified Himalayan resin, you can go straight to Therapium™ Shilajit Supreme.
What is Shilajit?
Shilajit (sometimes called mumijo, moomiyo, or "rock sweat") is a thick, blackish-brown exudate that forms over centuries from the slow decomposition of plant matter and minerals compressed between layers of rock at altitudes of 1,000–5,000 metres. The summer sun warms the mountain face, the resin softens and oozes out of crevices, and it is then carefully harvested, filtered, and purified.
Chemically, Shilajit is a complex matrix containing:
- Fulvic acid (15–20%) — the active "transporter" molecule that helps the body absorb minerals at the cellular level
- Humic acid — supports detoxification and gut integrity
- Dibenzo-α-pyrones (DBPs) — protect mitochondria from oxidative damage
- 84+ trace minerals in ionic form — including magnesium, zinc, iron, copper, selenium
- Amino acids and phospholipids
This unique composition is what makes Shilajit so different from a standard multivitamin or mineral supplement: the minerals are already bound to fulvic acid, meaning they cross cell membranes far more efficiently than synthetic equivalents.
How Shilajit works at a cellular level
The mechanism that has attracted the most research attention is Shilajit's effect on the mitochondria — the energy-producing organelles inside every cell. A 2010 study published in Journal of Medicinal Food showed that the dibenzo-α-pyrones in Shilajit act as electron reservoirs, helping mitochondria maintain ATP production even under metabolic stress.
In simpler terms: when your cells are tired, depleted or aging, Shilajit helps them keep producing energy efficiently instead of leaking electrons and creating oxidative damage.
This is also why Shilajit pairs naturally with other mitochondrial support nutrients. If you are interested in stacking, our Energy Stack combines NAD⁺ Supreme with Shilajit Supreme to support both the NAD⁺ coenzyme pathway and mitochondrial membrane integrity.
Evidence-based Shilajit benefits
1. Energy and physical stamina
A 2016 placebo-controlled trial published in the Journal of Ethnopharmacology followed healthy men aged 45–55 who took 250mg of purified Shilajit twice daily for 90 days. The Shilajit group showed a statistically significant increase in total testosterone, free testosterone and DHEAS compared to placebo — all of which contribute to sustained energy, muscle maintenance and recovery.
For active adults, this translates to less fatigue after training, faster recovery between sessions, and a steadier baseline of daytime energy without the crash associated with stimulants.
2. Testosterone and male vitality
The 2016 trial above is the most-cited evidence here. After 90 days, men taking Shilajit showed roughly a 20% increase in total testosterone and 19% in free testosterone over baseline. This is not a pharmaceutical-level increase but it is meaningful — and unlike testosterone replacement therapy, it works by supporting your own endocrine signalling rather than supplying exogenous hormone.
3. Cognitive performance and memory
Animal and early human studies suggest Shilajit's fulvic acid may help protect against the protein aggregation patterns seen in cognitive decline. A 2012 paper in the International Journal of Alzheimer's Disease proposed Shilajit as a "nutraceutical of choice" for age-related cognitive support, citing fulvic acid's ability to inhibit tau protein self-aggregation in laboratory models.
While larger clinical trials are still needed, many users report sharper focus and clearer recall within 4–6 weeks of consistent use.
4. Iron status and mild anaemia
A 2003 study in Phytotherapy Research reported that Shilajit supplementation significantly improved haemoglobin, haematocrit and red blood cell count in adults with iron-deficiency anaemia. The fulvic acid in Shilajit appears to enhance the absorption of dietary iron without the gastrointestinal side effects often associated with iron tablets.
5. Recovery and exercise adaptation
A 2019 trial in the Journal of the International Society of Sports Nutrition found that 500mg/day of Shilajit for 8 weeks reduced inflammation markers and improved muscle endurance in trained adults performing fatiguing exercise. The likely mechanism is a combination of mitochondrial support and reduced oxidative stress in recovering tissue.
6. Altitude and oxidative stress adaptation
Traditionally, Himalayan populations have used Shilajit to cope with the metabolic demands of high-altitude living. Modern research supports this: the dibenzo-α-pyrones appear to help cells maintain oxygen efficiency under hypoxic conditions.
How to take Shilajit: dosage, timing and form
Shilajit is sold in three main forms — and the differences matter:
- Purified resin (our preferred form) — the closest to the natural state, easy to dose precisely, no excipients. This is what Therapium™ Shilajit Supreme is
- Powder — usually a freeze-dried extract, convenient but quality varies wildly
- Capsules — convenient but often contain only 100–200mg per capsule, requiring multiple capsules to reach an effective dose
Recommended dosage: 300–500mg per day for healthy adults, taken once daily. A pea-sized portion of resin is roughly 300–500mg.
How to take resin: dissolve the pea-sized portion in a glass of warm (not boiling) water, herbal tea, or warm milk. Stir until fully dissolved, then drink. The taste is earthy and bitter — this is normal and indicates an unprocessed, authentic product.
Best time to take: morning or early afternoon, on an empty stomach for best absorption. Avoid taking close to bedtime as the energising effect can interfere with sleep in sensitive individuals.
How to choose a pure Shilajit
Shilajit is one of the most adulterated supplements on the market. Independent testing has found heavy metals, soil contamination and synthetic fillers in unbranded products sold on large marketplaces. When choosing a Shilajit supplement, look for:
- Source transparency — Himalayan or Altai origin, with a stated altitude band
- Standardised fulvic acid content — at least 15%
- Independent heavy metal testing — Certificate of Analysis (COA) available on the brand's website
- GMP / ISO certified manufacturing
- Pure resin or standardised extract — avoid products that list "Shilajit" as one of many ingredients in a proprietary blend
You can view the full Certificate of Analysis for our Shilajit batch (and every other Therapium™ product) on our COA & lab testing page.
Safety, side effects and who should not take Shilajit
Purified Shilajit is generally well tolerated. The most commonly reported side effects in clinical trials are mild and transient: digestive adjustment in the first week, very rarely a slight increase in body temperature, and occasionally vivid dreams when taken too close to bedtime.
Do not take Shilajit if you:
- Are pregnant or breastfeeding (insufficient safety data)
- Have haemochromatosis or any iron-overload disorder
- Have an active gout flare (Shilajit may raise uric acid in sensitive individuals)
- Are taking iron supplements or blood thinners without medical supervision
As with any supplement, if you are taking prescription medication or have a chronic health condition, consult your doctor before starting Shilajit. We have a more general advisory on supplement-medication interactions in our FAQ.
When will I notice results?
Shilajit is not a stimulant — you will not feel an immediate hit like you might from caffeine. Realistic expectations:
- Week 1–2: subtle improvements in steady daytime energy, easier mornings
- Week 3–6: better workout recovery, fewer "crash" afternoons, improved focus
- Week 8–12: hormonal markers (in men), endurance, and general resilience reach a new baseline
For best results, combine consistent daily dosing with adequate sleep, a mineral-rich diet, and resistance training appropriate to your fitness level.
Shilajit vs other adaptogens and energy supplements
A common question: how does Shilajit compare to other natural energy supports like Ashwagandha, Rhodiola or NAD⁺ precursors?
Each works through a different mechanism. Adaptogens like Ashwagandha primarily modulate the stress response (cortisol). NAD⁺ precursors restore a coenzyme essential for over 500 enzymatic reactions, including DNA repair. Shilajit is unique because it works directly on mitochondrial energy production and mineral status — making it complementary rather than competitive with those compounds.
For people specifically interested in cellular and mitochondrial longevity, stacking Shilajit with NAD⁺ is one of the most evidence-aligned combinations available — which is why we offer them as a single Energy Stack.
The bottom line
Shilajit is one of the few traditional remedies with a growing modern evidence base across multiple domains: energy, hormonal balance, recovery, cognitive support and iron status. The two things that determine whether it works for you are purity and consistency.
Therapium™ Shilajit Supreme is harvested from the Himalayan range, gravity-filtered, freeze-dried using a low-temperature process to preserve fulvic acid, and independently tested for heavy metals on every batch. If you want to experience clean Himalayan resin without the guesswork, explore our Shilajit Supreme or the Energy Stack with NAD⁺.
