In the jar it looks like tar, in the glass it becomes coffee-colored water. Just melt a tip and shilajit, according to the promise that made it viral, should accompany the day with more energy, greater concentration and less hunger. A perfect hat trick for social media and supplement shelves.
The research offers a more interesting story than the simple alternative between miracle and failure. Some human studies have found favorable effects on strength after exercise, bone density and specific biomarkers.
What is shilajit and what does it contain
They call it “Himalayan resin”, although from a chemical point of view the definition is rather elastic. Shilajit, also known as mumijois a dark organic-mineral substance that emerges from the rocks of various Asian mountainous regions. It contains humic and fulvic acids, organic compounds and minerals in variable proportions, determined by origin and processing.
The European Commission classifies it as a new food in ordinary food uses, while it recognizes a history of consumption prior to 1997 in supplements. The percentage of fulvic acid helps to describe the product, but alone does not certify effectiveness and purity. Clinical studies have examined precise doses and formulations; a jar with the same word on the front can have a different composition.
Shilajit and energy
In studies, energy primarily means strength and response to fatigue during controlled exercise. It is a narrower field than daily fatigue, but also the most promising for this supplement.
The post-exercise strength trial
In a 2019 randomized study, 63 young, active men took 250 or 500 milligrams per day of a purified extract, or a placebo, for eight weeks. After one hundred leg extensions, the higher dose helped maintain isometric strength, especially in initially stronger participants. The lower dose did not show the same benefit. The outcome concerns muscle capacity after a strenuous protocol, without measuring drowsiness or fatigue related to medical conditions. The signal remains interesting, even if with a precise perimeter.
The small study on fatigue in 2026
A pilot trial published in January 2026 followed 25 healthy, moderately active men taking 500 milligrams per day of a resin for 28 days. Reported fatigue score decreased by 32.4% and dominant hand strength increased by 5.7%. There was no placebo and control group, so expectations and familiarity with the tests may have contributed, but it is still a favorable result to be confirmed.
Shilajit for hunger and concentration
Hunger and concentration are among the words most often associated with this supplement. Let’s see what the scientific literature thinks about it.
Does shilajit take away hunger?
Available clinical studies have not adequately measured hunger, satiety, or amount of food consumed. However, in 2025 a trial on people with risk factors for metabolic syndrome combined diet and exercise with various supplements.
Shilajit appeared in small quantities along with chromium and extract of Phyllanthus emblica; after 12 weeks, most differences in body composition compared to placebo were not significant. Its specific effect on hunger cannot be isolated, but a possible support for physical performance could help some people follow training with greater continuity.
Can it increase concentration?
In 2023, researchers observed shilajit fractions from the Chilean Andes on cultured rat neurons, mouse neuroblastoma cells, and cell-free systems. Some fractions promoted the growth of neuronal extensions and reduced the aggregation of the tau protein, involved in neurodegenerative diseases. The experiment indicates a biological path to be explored further.
Testosterone, bones and collagen
Some positive results come from very specific groups. A trial in healthy men between 45 and 55 years old found an increase in total and free testosterone after 90 days with 250 milligrams of purified extract twice daily compared to placebo. It is not a therapy for hypogonadism or infertility, conditions that require medical diagnosis and treatment.
In a 48-week study of 60 postmenopausal women with osteopenia, 250 and 500 milligrams per day were associated with better preservation of bone mineral density. A trial of 35 trained young men recorded an increase in type I pro-collagen after eight weeks. The biomarker does not guarantee stronger tendons or firmer skin. However, there are concrete lines of research.
Purity and safety: analyzes make the difference
The raw material is born between rock and organic substance, therefore it can bring with it metals and microorganisms. Purification and batch control serve to make the product suitable for consumption. In 2025, a study of 14 raw samples and six commercial supplements found thallium in both categories, up to 0.5 micrograms per gram in finished products. The number of supplements was small and the work does not describe the entire market; demonstrates the utility of numerical analyses, including thallium.
The certificate of analysis should refer to the batch of the package and come from an independent, possibly accredited, laboratory. The values of lead, arsenic, mercury, cadmium and thallium matter more than the word “tested”. In Italy you can also check the Register of food supplements of the Ministry of Health, which allows their marketing.
Short-term studies suggest fair tolerability for the purified extracts at the doses tested. Data on prolonged use and interactions remain limited. The US Operation Supplement Safety program reports allergic reactions, dizziness, disorientation and changes in blood pressure among the reported events.
FAQ about shilajit
Dose, time and form change from one package to another, because “shilajit” does not identify a unique extract. Useful answers therefore start from the available studies and always return to the label of the chosen product.
How much shilajit do you take per day?
In trials, 250-500 milligrams per day are often used; some biomarker studies have used larger amounts. There is no universal dose valid for different resins and extracts. It is best to follow the instructions on the package, without exceeding them, and ask a doctor or pharmacist for advice in the presence of therapies or pathologies.
Is it better to take shilajit in the morning or in the evening?
There is a lack of clinical comparisons between different times. The morning is often suggested because the product is sold for energy and fits easily into the routine. Personal tolerability and label instructions offer more concrete indications of the watch.
Resin, capsules or gummies: which form to choose?
The resin retains traditional texture and taste; capsules and tablets simplify dosing. The gummies they can add sugars. No form has demonstrated overall superiority: traceability, declared quantity and batch certificate come before consistency.
Who should avoid shilajit?
Pregnancy, breastfeeding and pediatric age do not have adequate data. Anyone who takes medications or lives with kidney, liver, cardiovascular, hormonal or iron accumulation-related diseases should speak to a healthcare professional. Persistent tiredness deserves evaluation, because it may depend on anemia, thyroid, sleep or other causes that the jar does not diagnose.
Does shilajit make you lose weight?
Today there is no clinical evidence that attributes a reduction in hunger or weight loss to shilajit. Those who choose it to support physical activity and recovery can evaluate it for that goal, separating it from the promise to eat less.
Where does the evidence on shilajit arrive today?
Shilajit has a long tradition and some modern achievements worthy of attention. Strength after exercise, bone health and specific biomarkers are the most concrete fields; hunger and concentration require dedicated clinical studies. It is also important to know which extract you are taking.
Anyone evaluating the purchase can check the form, quantity per dose and analysis relating to the batch. The results obtained with standardized extracts do not allow us to predict the effect of every commercially available resin.
An example available online: ESN Shilajit+ in capsules
Among the formulations available online, ESN Shilajit+ offers some more verifiable elements. In the list of notified supplements, updated to July 1, 2026, it appears with the exact name “ESN SHILAJIT +”, associated with Fitmart GmbH & Co and code 206022.
The package contains 60 vegan capsules and the indication is to take one per day. Each capsule provides 500 milligrams of 4:1 shilajit extract, equivalent to 2,000 milligrams of the raw material from which the extract is obtained. The larger figure reported in the title of the Amazon listing, therefore, does not indicate 2,000 milligrams of extract actually present in the capsule.
The formula also contains vitamins C, B6 and B12 and black pepper extract. Vitamins can contribute to normal energy metabolism and the reduction of tiredness and fatigue; These recognized effects relate to the added micronutrients and do not, by themselves, demonstrate that shilajit increases energy or concentration. However, the capsule form allows you to know better the quantity taken compared to resins dosed by eye, where a “tip” can mean many things.
For those who prefer a formulation already dosed, vegan and notified in Italy, ESN Shilajit+ therefore represents a more easily verifiable proposal. The cautions indicated in the article remain valid: the studies examined specific extracts, the ministerial notification does not replace batch analyzes and a supplement does not resolve the medical causes of persistent tiredness.
