Shilajit
Ancient Ayurvedic mineral resin containing fulvic acid and trace minerals, studied for testosterone support, mitochondrial function, and cognitive health
Bottom Line
Shilajit is a sticky, tar-like substance that oozes from Himalayan and other mountain rocks, formed over centuries from decomposed plant matter. It's been a cornerstone of Ayurvedic medicine for thousands of years, and modern research is beginning to validate some traditional claims.
The most compelling evidence is for testosterone support in middle-aged men (19% increase in one RCT) and sperm quality improvements. The fulvic acid content may enhance mitochondrial function and nutrient absorption. However, most studies are small, and quality control is a significant concern with many products.
Worth trying for men over 40 seeking natural testosterone support or anyone interested in traditional adaptogens. Quality matters enormously - choose purified extracts from reputable brands with heavy metal testing. Start with 250-500mg daily and assess after 8 weeks.
Science
What is Shilajit?
Shilajit (also called mumie, moomiyo, or mineral pitch) is a blackish-brown resinous substance found in rocks at high altitudes (1,000-5,000m) in the Himalayas, Altai, Caucasus, and other mountain ranges. It forms over centuries from the slow decomposition of plants by microorganisms.
Key Bioactive Components:
| Component | Concentration | Function |
|---|---|---|
| Fulvic acid | 60-80% | Primary bioactive, antioxidant, nutrient transport |
| Humic acid | 10-20% | Chelation, immune modulation |
| Dibenzo-alpha-pyrones (DBPs) | Variable | Mitochondrial support, energy |
| Trace minerals | 80+ minerals | Zinc, iron, magnesium, selenium, etc. |
| Amino acids | Variable | Protein building blocks |
Mechanisms:
1. Mitochondrial Function:
- Fulvic acid and DBPs support electron transport chain
- May increase CoQ10 levels in tissues
- Enhances ATP production
- Studies show improved exercise capacity and reduced fatigue
2. Testosterone & Reproductive Health:
- Pandit et al. (2016): 250mg twice daily for 90 days increased total testosterone by 19% and free testosterone by 20% in healthy men aged 45-55
- Biswas et al. (2010): Improved sperm count (+61%), motility, and testosterone in infertile men
3. Cognitive Support:
- Fulvic acid may inhibit tau protein aggregation (Alzheimer's mechanism)
- Traditional use for memory and mental clarity
- Carrasco-Gallardo et al. (2012): Reviewed neuroprotective potential
4. Nutrient Absorption:
- Fulvic acid enhances mineral bioavailability
- Acts as a natural chelator
- May improve absorption of other supplements
Traditional Uses (Ayurveda):
- Rasayana (rejuvenator) - considered one of the most powerful
- "Conqueror of mountains and destroyer of weakness"
- Used for weakness, sexual dysfunction, diabetes, cognitive decline

Shilajit for male fertility and sperm quality
Sal presents a 2010 study where 60 infertile men took 100mg of shilajit twice daily for 90 days. 60% saw dramatic increases in sperm count and 12% had improved sperm motility.
"So these are men with low enough sperm counts where they're considered infertile. They gave them 100 milligrams of Shilajit twice a day for 90 days. In 60% of them, there was a dramatic increase in sperm count and sperm motility in 12%."
Muscular strength recovery and testosterone studies
A 2019 study of 63 men found eight weeks of shilajit reduced fatigue-induced declines in muscular strength and lowered collagen breakdown markers. A 2016 gold-standard randomized double-blind study also showed testosterone increases.
"A 2019 study of 63 men found that eight weeks of Shilajit supplementation reduced fatigue-induced declines in muscular strength and lowered levels of a marker of collagen breakdown. In other words, it helped with recovery."
Quality sourcing and PrimaVie
The hosts warn about fake shilajit flooding the market and recommend PrimaVie as the standardized source from the Himalayas, noting Organifi uses PrimaVie in their products.
"They source them from the real Himalayan Shilajit that's standardized. Have you guys ever tried other brands of Shilajit? Disgusting. It's disgusting. It's terrible."
Shilajit: How To
That's timeline.com/slash ben35 while the offer lasts. You may have heard of Shilajit before.
"You may have heard of Shilajit before. Shilajilajilajit. It's fun to say it comes from the Himalayas. A lot of it is just nasty and full of all the things you'll find in soil, especially heavy metals."
What is shilajit and its key bioactive compounds
Darin explains that shilajit is a natural tar-like substance formed from centuries of plant decomposition, rich in fulvic acid, humic acids, amino acids, antioxidants, and essential minerals. He frames it as a foundational tonic rather than a targeted supplement.
"the main thing that this breaks into or transforms itself into is fulvic acid, as well as other humic acids. And then, of course, there's amino acids, there's a huge amount of antioxidants. And the big thing, I think, is all many of the essential minerals and electrolytes that our body needs."
Studies on testosterone, bone density, and antioxidant effects
Darin reviews multiple studies showing shilajit's antioxidant activity, anti-inflammatory properties, cognitive benefits, testosterone increases in healthy males, and bone mineral density preservation in postmenopausal women.
"testosterone levels. Even dating back in the Ayurvedic texts, they have long touted Sheilajit's ability to enhance males' fertility and sexual functioning. The modern research has found that Sheilajit may increase testosterone levels and improve sperm quality."
Dosing protocol and quality sourcing
Darin shares his personal dosing protocol of about 1000mg per day and recommends Mana Vitality for quality sourcing, emphasizing the importance of packaging and purity.
"So I consume about a thousand milligrams of SheilaJit a day, sometimes less, sometimes more. I use a company that I believe has got the highest sourcing."

Shilajit neuroprotective effects from 2024 study
Sal presents a 2024 study showing shilajit reduced amyloid beta-induced cytotoxicity in brain cells, suggesting neuroprotective benefits and potential relevance to Alzheimer's prevention.
"They found that Shilajit reduced amyloid beta-induced cytotoxicity in certain cells in the brain. In other words, probably good for brain health. So neuro, there's some neuroprotective effects."
Bone density RCT in postmenopausal women
A 2022 randomized double-blind placebo-controlled trial of 60 postmenopausal women with osteopenia found dose-dependent preservation of bone mineral density in the lumbar spine with shilajit supplementation.
"there was a 2022 randomized double-blind placebo-controlled trial that examined Shalajit's effects on bone health in postmenopausal women with osteopenia. So 60 participants got 250 or There was a dose-dependent preservation of bone mineral density in the lumbar spine, along with reduced oxidative stress and inflammation."
Quality sourcing and PrimaVie recommendation
The hosts warn about fake and low-quality shilajit products flooding the market and recommend PrimaVie as the trusted standardized source used in clinical studies.
"The thing with Shilajit, though, is you can get crappy Shilajit or you can get fake Shilajit."
The one that I sell comes from Russia
And now Shilajit, fulvic acid and humic acid have been used by farmers to mitigate metal toxicity in soil, whether it's molybdenum or cadmium, and it does the same thing in our body.
"any company that they can find and they're not doing their research and maybe they fake the lab report. There are a lot of issues even with these high-end supplement companies where you can have heavy metal contamination. So it's really important to do your research on the brand and really trust the brand that you're taking because it could be a huge source of your heavy metal intake is through your Shilajit supplement if it's a bad source."
