Shilajit and Testosterone: Himalayan Rock-Tar Extract with Up to 85 Ionic Minerals

Shilajit is a dark tar like rocky substance collected from the deep rocks of Himalaya. It’s considered to be one of the cornerstones of Ayurveda (Indian medicine) and its use dates back thousands of years.

Even in the western medicine (where Shilajit is rather new thing) it’s considered to be a healing substance, mainly due to the fact that it’s claimed to contain more than 85 different minerals in their ionic form (bound to fulvic acid).

Shilajit can also apparently increase testosterone levels, promote healthy semen production, and slightly boost hemoglobin levels.

Shilajit, Fulvic Acid, and Testosterone

shilajit testosteroneNot much research has been done to determine what shilajit actually is, but the most accepted theory seems to be that it’s millions of years worth of composed plant matter that has developed into this extremely nutrient-rich rocky-tar in between the Himalayan deep rocks.

Several studies and patent applications have reported shilajit to contain 70-85 minerals in their ionic form, with other organic compound such as resins, humic acid, fulvic acids, fatty-acids, amino-acids, triterpenes, benzoic acid, multiple enzymes, and steroidal saponins.

Perhaps the most interesting benefit of shilajit is its high fulvic acid content (10-20%). Fulvic acid is considered to be one of our nature’s most powerful electrolytes which is created by soil-based micro-organisms to make vitamins and minerals assimilate better inside plants. The electron-donor benefits of fulvic acid might be one of the reasons why shilajit has been found to increase testosterone (more about that in a bit).

When it comes to scientific studies on the uses and benefits of shilajit supplements, there aren’t many, but the effects are – more or less – impressive.

In 2010, Indian researchers gave their 35 infertile test-subjects 200mg/day of shilajit extract for 90 consecutive days. When the hormone and sperm parameters were compared from day 1 to day 90, the research noted following improvements;

  • Total sperm count rose by 61%.
  • Sperm quality increased by 37%.
  • Serum testosterone levels increased by 23%, and FSH rose by 9%.
  • Markers of oxidative damage also went down, whereas hemoglobin slightly increased.

One more recent study from 2015 (sponsored by shilajit manufacturer PrimaVie) showed that in healthy volunteers aged between 45-55 years, 250mg/day of shilajit extract for 90 days was able to;

  • Increase total-testosterone levels by 20%
  • Increase free-testosterone levels by 19%
  • Boost DHEA levels by 31% while maintaining normal LH and FSH levels.

Shilajit also has a potential nootropic effect, on smaller animal studies it has been noted that shilajit can activate the hypothalamic glycine and GABA-receptors of rodents, this should have a “calm and relaxing” effect on the brain, reduce anxiety, and promote sleep quality. One rat study actually tested shilajit as a treatment for chronic fatigue syndrome and found significant improvements. Two other studies have theorized that shilajit could be effective for protection against Alzheimer’s disease (study, study).

There’s plenty of snake oil salesmen in the shilajit market trying to sell anything black as shilajit. To get the real deal you should always use the actual resin form of shilajit supplements from trusted and tested brands with years of experience in manufacturing, instead of jumping on the claims of some smaller supplement companies with their shady low-priced products.


Shilajit is a nutritional powerhouse of fulvic acid, ionic minerals, enzymes, and a massive amount of various phytonutrients. 

The research on shilajit is still in baby-steps (only 61 scientific publications available as of May 2016), but the evidence so far is impressive and I’m positive there will be more research either proving shilajit to be useful Ayurvedic supplement, or just another supplemental non-starter. Time will tell…

    I assume you don’t have to cycle this?

    • Global on 14/07/2014 at 13:45

      I dont think so, it’s minerals. Unlike herbs which has substances that act like poison, which is why we build tolerance to most of them.

      • Ali Kuoppala on 14/07/2014 at 18:00

        Pretty much this, Shilajit is basically not a herb so it shouldn’t contain the phytoalexin compounds which act as the plants “natural defence” system and can cause resistance in the body.

        However there’s a theory on the formation of Shilajit which states that it’s millions of years of old plant mass that has been fossilized and preserved inside the Himalayan rocks where it oozes out when the weather gets hot.

        So basically it might be hundreds of ancient herbs in fossilized form (which would explain the high amount of minerals) but that’s only a theory and I don’t think that there would be anymore active phytoalexins left in the rocky tar anymore if the plants are millions of years old 😀

        So I’d say that you’re fine without cycling.

      Would like an answer to this too, as I’ve made a tincture out of this.

    Pürblack claims that the 85 minerals are just an hype, and I can’t find any information online which backup the 85 minerals claim. The most informative I can find is Pürblacks lab tests.

    Do you have anything to backup 85 minerals, Ali?

    • Ali Kuoppala on 01/08/2014 at 20:50

      Hey, thanks for pointing that out, I wasn’t even aware that it’s a market hype.

      As a matter of fact I’ve never seen an actual study citing all the minerals, I’ve only seen some review studies listing a whole lot of them for certain medical conditions, but I didn’t count how many there was 😀

      I’ve always just believed the hype I guess, so many big reputable names have already tossed out the “85 ionic minerals” claim that I was too confident on it…

      …Seems like I may have been wrong.

      I have to do some more research, but other than that it’s still a substance with a shit ton of minerals, resin, and fulvic acid.

    I get my Shilajit from a this little shop that is reputed as being legit, and I have no reason to think otherwise. However, their Shilajit is in powder form, and this article is the first that hints to that being cause of suspicion. Anyway, it’s got a pungent smell. Like a horse, or a horse stable, but I certainly don’t feel worse after a few months of daily consumption, and I’d say I feel way more beastly in general, but I also use Pine Pollen, Chaga, and Tongkat Ali.

    Anyway, as far as Shilajit is concerned, I mix it 50/50 with Ashwagandha powder and make my own vegi-cap pills. Apparently the synergy is great with these two Indian denizens, and so far I concur.

    I have been using a cheaper brand, and highly recommend this product! I was looking for something to restore my energy and balance to hormomal system. I tried many natural health alternatives…

    Shiajit is one of the most potent supplements you can take. Just try some. It’s harmless, and you only have something to gain.

    • justd80010 on 29/08/2017 at 10:37

      I wouldn’t say “harmless.” My experience is that taking it on an empty stomach creates a general state of unease, light-headedness, and symptoms that are consistent with either low blood sugar or low blood pressure (sweating, clammy skin, woosiness) with symptoms lasting between 2-4 hours.

      I would caution to take only 250 mg (grain of rice size) and to only take this substance with meals.

      It’s good stuff (whatever it really is) and taken in moderation, with food, is unlikely to cause harm in otherwise healthy, adult individuals.
