Key Takeaways

Shilajit is one of the most mineral-dense substances on Earth — containing 85+ ionic minerals, fulvic acid (50–60%), humic acid, and dibenzo-alpha-pyrones formed over centuries in Himalayan rock.

Clinical trials in humans demonstrate real benefits — including significant increases in total and free testosterone, preserved bone mineral density in postmenopausal women, and boosted collagen synthesis.

Fulvic acid is the key bioactive — it acts as a natural electrolyte and molecular carrier that enhances nutrient absorption while providing independent antioxidant and anti-inflammatory activity.

Effective dosages range from 250–500 mg daily — with most studies using purified extract standardized to fulvic acid content. Benefits typically emerge after 8–12 weeks of consistent use.

Purification matters enormously — raw shilajit can contain heavy metals and contaminants. Only use products made from purified, standardized extract with third-party testing.

Modern delivery formats work — well-formulated gummies and tablets deliver the same bioactives as traditional resin with better dosing precision and compliance.

What Is Shilajit? Origins and Composition

Pure shilajit resin with measuring guidance — dosage matters for safety and efficacy.

Shilajit (pronounced shee-lah-jeet) is a sticky, tar-like resin that seeps from cracks in high-altitude rock formations, primarily in the Himalayas, Altai, Caucasus, and Andes mountain ranges. The word comes from Sanskrit, roughly translating to "conqueror of mountains" or "destroyer of weakness" — a fitting name for a substance that has been a cornerstone of Ayurvedic medicine for over 3,000 years.

But shilajit is not a plant extract, a mineral supplement, or a vitamin. It is something entirely different: a geological-biological hybrid formed over centuries as ancient plant matter (primarily mosses and liverworts) was trapped between layers of rock, slowly compressed by tectonic pressure, and transformed by microbial metabolism into a dense, mineral-rich resin.

This process — which scientists describe as a combination of humification and geological compression — concentrates an extraordinary array of bioactive compounds into a single substance:

Fulvic acid (50–60%) — the primary bioactive, a complex organic acid with powerful chelating and antioxidant properties

Humic acid — a larger molecular-weight organic acid that supports gut health and immune function

Dibenzo-alpha-pyrones (DBPs) — unique compounds that support mitochondrial electron transport chain function

DBP-chromoproteins (DCPs) — carrier proteins that enhance the bioavailability of DBPs

85+ trace minerals in ionic form — including iron, zinc, magnesium, copper, selenium, manganese, and others in their most bioavailable state

Amino acids, lipids, and plant-derived sterols

What makes this composition so remarkable is that these compounds do not simply coexist — they interact synergistically. The fulvic acid acts as a natural carrier molecule, enhancing the absorption and cellular delivery of the minerals and DBPs. This is why whole shilajit extract consistently outperforms its isolated components in research.

In traditional Ayurvedic texts, shilajit is classified as a rasayana — a category reserved for the most powerful rejuvenating substances in the entire pharmacopeia. It was prescribed for vitality, longevity, cognitive function, and physical strength. Modern science, as we will see, is increasingly validating these traditional uses with controlled clinical trials.

How Shilajit Works: The Fulvic Acid Mechanism

To understand why shilajit benefits are so broad — spanning energy, hormones, bones, brain health, and beyond — you need to understand the molecule doing most of the heavy lifting: fulvic acid.

Fulvic acid is not just another antioxidant. It is one of nature's most effective molecular carriers. With an extremely low molecular weight (typically under 2,000 daltons) and both hydrophilic and hydrophobic properties, fulvic acid can:

1. Chelate minerals into bioavailable complexes — binding to ionic minerals and converting them into forms that cells can actually absorb and use

2. Cross cell membranes efficiently — carrying nutrients directly into cells and mitochondria where they are needed

3. Donate and accept electrons — functioning as a potent redox agent that neutralizes free radicals without becoming a free radical itself (unlike many antioxidants)

4. Support electrolyte balance — acting as a natural organic electrolyte that enhances cellular hydration

This carrier function is why fulvic acid benefits extend far beyond simple antioxidant activity. When you take shilajit, the fulvic acid is not just protecting your cells from oxidative damage — it is actively delivering the 85+ minerals and the energy-supporting DBPs directly into your mitochondria.

Research Spotlight: Mitochondrial Energy

A study published in the Journal of Ethnopharmacology found that shilajit (standardized to DBPs, DCPs, and fulvic acids) reversed chronic fatigue by preserving mitochondrial membrane potential and stabilizing electron transport chain enzyme activity (complexes I, II, IV, and V). The researchers concluded that mitochondria represent "a potential target for treatment of CFS" and that shilajit works by modulating both the HPA axis and mitochondrial bioenergetics.

Surapaneni et al., J Ethnopharmacol, 2012. DOI: 10.1016/j.jep.2012.06.002

Think of it this way: your mitochondria are the power plants inside every cell, converting nutrients into ATP (cellular energy). Shilajit's DBPs plug directly into the electron transport chain — the final step of energy production — while its fulvic acid delivers the trace minerals (iron, copper, zinc) that these enzymes require as cofactors. The result is more efficient energy production at the most fundamental level.

This is not a stimulant effect. There is no caffeine, no crash, no adrenal taxation. Shilajit supports energy production by making your mitochondria work better, not by overriding your body's natural signals.

7 Evidence-Based Shilajit Benefits

Modern shilajit gummies make daily supplementation convenient and enjoyable.

The shilajit benefits listed here are not drawn from folklore or marketing claims. Each is supported by peer-reviewed research, much of it from randomized, controlled human trials. Let us walk through them.

1. Supports Healthy Testosterone Levels

This is the benefit that put shilajit on the map in the West, and it holds up under scrutiny.

Research Spotlight: Testosterone

In a randomized, double-blind, placebo-controlled trial, healthy men aged 45–55 received 250 mg of purified shilajit twice daily for 90 days. Compared to placebo, the shilajit group showed statistically significant increases in total testosterone, free testosterone, and DHEAS (P < 0.05), while gonadotropic hormones (LH and FSH) remained stable — indicating the increase was not from artificial overstimulation of the pituitary.

Pandit et al., Andrologia, 2016; 48(5):570-5. DOI: 10.1111/and.12482

A 2023 systematic review in the International Journal of Impotence Research, which evaluated 52 studies on 27 proposed "testosterone boosters," classified purified shilajit extract as "possibly effective" for men with late-onset hypogonadism — one of only a handful of natural compounds to earn that distinction. (Morgado et al., 2023)

The mechanism appears to involve both direct effects on testicular steroidogenesis (upregulating the enzymes 3-beta-HSD and 17-beta-HSD that synthesize testosterone) and indirect effects through reduced oxidative stress in testicular tissue.

2. Enhances Energy and Reduces Fatigue

Shilajit's energy benefits operate through a fundamentally different pathway than stimulants. As described above, its DBPs and fulvic acid work synergistically to optimize mitochondrial electron transport chain function, stabilize mitochondrial membrane potential, and reduce oxidative stress within the mitochondria themselves.

In the chronic fatigue model study, shilajit reversed fatigue-induced behavioral changes and preserved the activity of all four measured mitochondrial enzyme complexes. It also normalized HPA axis markers, suggesting it helps regulate the stress-energy axis rather than simply overriding it.

For practical purposes: users typically report more sustained energy throughout the day, better exercise recovery, and reduced afternoon fatigue — effects that build gradually over 2–4 weeks of consistent use.

3. Promotes Bone Mineral Density

Research Spotlight: Bone Health

A 48-week randomized, double-blind, placebo-controlled trial in 60 postmenopausal women with osteopenia found that shilajit extract (250 mg or 500 mg daily) dose-dependently preserved bone mineral density of both the lumbar spine and femoral neck, while the placebo group experienced progressive bone loss. Shilajit also significantly reduced markers of bone turnover (CTX-1, BALP, RANKL), increased the protective factor OPG, reduced inflammation (hsCRP), and decreased oxidative stress (MDA) — all at P < 0.001 vs. placebo.

Pingali & Nutalapati, Phytomedicine, 2022; 105:154334. DOI: 10.1016/j.phymed.2022.154334

This is a remarkable finding. Postmenopausal bone loss is driven by estrogen withdrawal, increased oxidative stress, and chronic low-grade inflammation — and shilajit addressed all three pathways simultaneously. The fact that benefits were dose-dependent (500 mg outperformed 250 mg) adds confidence to the causal relationship.

4. Boosts Collagen Synthesis

Two clinical trials from the University of Nebraska-Lincoln demonstrated that shilajit upregulates collagen production at both the gene expression and protein levels.

In the first study, 8 weeks of shilajit supplementation (250 mg twice daily) significantly upregulated a cluster of 17 extracellular matrix genes in skeletal muscle — including collagen, elastin, fibrillin, decorin, and fibronectin — in overweight adults. (Das et al., J Med Food, 2016)

The second study measured actual circulating collagen: 8 weeks of shilajit supplementation (500 mg and 1,000 mg/day) produced statistically significant increases in serum pro-c1-alpha-1, a direct biomarker of type I collagen synthesis (P = 0.008 for low dose, P = 0.007 for high dose). The placebo group showed no change. 75% of participants in the high-dose group exceeded the minimal clinically important difference. (Neltner et al., J Diet Suppl, 2023)

This has implications beyond bodybuilding. Type I collagen is the most abundant structural protein in the human body, critical for skin elasticity, joint health, tendon integrity, and bone strength.

5. Improves Male Fertility and Sperm Quality

A clinical trial in 35 oligospermic (low sperm count) patients found that 90 days of processed shilajit (200 mg/day) produced significant improvements across every measured parameter: total sperm count increased by 61.4%, sperm motility improved by 12–17%, normal sperm count rose by 18.9%, and serum testosterone increased by 23.5%. Oxidative stress markers in semen decreased by 18.7%. (Biswas et al., Andrologia, 2010)

The mechanism is twofold: shilajit's antioxidant activity protects sperm cells from oxidative damage (a leading cause of male infertility), while its androgenic properties support the hormonal environment necessary for healthy sperm production.

6. Supports Skin Health and Microcirculation

A clinical trial in healthy adult women found that 14 weeks of shilajit supplementation (250 mg twice daily) induced genes relevant to endothelial cell migration and blood vessel growth, and measurably improved skin microperfusion compared to baseline and placebo. Gene expression analysis confirmed upregulation of extracellular matrix and vascular remodeling pathways. (Das et al., J Am Coll Nutr, 2019)

Improved microcirculation means better delivery of oxygen and nutrients to skin cells — which, combined with the collagen-boosting effects described above, suggests meaningful benefits for skin aging.

7. Supports Muscular Strength and Recovery

A randomized controlled trial in 63 recreationally active men showed that 8 weeks of shilajit supplementation at 500 mg/day significantly reduced fatigue-induced loss of muscular strength. The high-dose group retained significantly more maximal voluntary isometric contraction strength after a fatiguing protocol compared to both the low-dose and placebo groups (8.9% decline vs. 16–17% decline). Baseline hydroxyproline (a marker of collagen breakdown) was also significantly lower. (Keller et al., J Int Soc Sports Nutr, 2019)

The practical implication: shilajit may help you maintain strength output during demanding workouts and recover faster between sessions.

Ingredient Spotlight: What Makes Shilajit Unique

Shilajit's effects come from the interplay of its three primary bioactive groups. Here is what each one does and why they work better together than alone.

Fulvic Acid

What it is: A low-molecular-weight organic acid (under 2,000 daltons) produced during the humification of plant matter. Makes up 50–60% of purified shilajit extract.

What it does:

Chelates minerals into bioavailable ionic complexes that cross cell membranes

Acts as a bidirectional electron donor/acceptor — one of nature's most versatile antioxidants

Supports gut barrier integrity and nutrient absorption

Reduces systemic inflammation (demonstrated by hsCRP reduction in clinical trials)

May enhance the bioavailability of co-administered supplements

Why it matters: Fulvic acid is the reason shilajit is more than the sum of its mineral parts. Without this carrier molecule, the trace minerals would have significantly lower absorption. Fulvic acid benefits extend to virtually every system in the body because it operates at the level of cellular transport itself.

Humic Acid

What it is: A higher-molecular-weight organic acid (typically 10,000–100,000 daltons) that works alongside fulvic acid. Less bioavailable systemically, but highly active in the gut.

What it does:

Supports gut barrier function and intestinal mucosal health

Binds to toxins and heavy metals in the digestive tract, preventing absorption

Provides prebiotic-like support for beneficial gut microbiota

Complements fulvic acid's systemic activity with local GI protection

Why it matters: Humic acid explains why shilajit has been traditionally used for digestive health. It acts as a natural detoxification agent in the gut while supporting the microbial environment that influences everything from immunity to mood.

Trace Minerals & Dibenzo-Alpha-Pyrones

What they are: Over 85 minerals in their most bioavailable ionic form (iron, zinc, magnesium, selenium, copper, manganese, chromium, and many more) plus dibenzo-alpha-pyrones (DBPs), unique compounds found almost exclusively in shilajit.

What they do:

DBPs directly participate in mitochondrial electron transport, enhancing ATP production

DBP-chromoproteins (DCPs) act as carrier molecules that protect and deliver DBPs to target tissues

Ionic minerals serve as essential cofactors for hundreds of enzymatic reactions

The mineral profile addresses subclinical deficiencies common in modern diets

Why they matter: This is shilajit's energy signature. The DBPs are what differentiate shilajit from a simple fulvic acid supplement or a multivitamin. They are the direct mitochondrial activators that, when delivered by fulvic acid alongside the necessary mineral cofactors, produce the sustained energy effects users report.

Shilajit Dosage Guide: How Much to Take

Fulvic acid — the key bioactive compound in shilajit — bridges ancient Ayurveda and modern science.

Getting the shilajit dosage right matters. Too little, and you will not reach the therapeutic threshold demonstrated in clinical research. Too much is unlikely to cause harm (no adverse effects have been reported in studies using up to 1,000 mg/day), but there is a point of diminishing returns.

Here is what the clinical evidence supports:

General wellness and energy: 250 mg/day of purified extract (the minimum effective dose in most studies)

Testosterone and male health: 500 mg/day (250 mg twice daily), consistent with the Pandit et al. testosterone trial

Bone health: 250–500 mg/day, with higher doses showing greater benefit (Pingali & Nutalapati, 2022)

Collagen and muscle support: 500 mg/day (Keller et al., 2019; Neltner et al., 2023)

Fertility: 200 mg/day was effective in the Biswas et al. trial

Timing: Take with food, ideally in the morning or early afternoon. Splitting the dose (e.g., 250 mg morning and 250 mg midday) mirrors the protocols used in most clinical trials. Avoid taking late in the evening, as some users report that the energy-supporting effects can interfere with sleep onset.

Duration: Plan for a minimum of 8 weeks. The testosterone trial ran for 90 days, the bone density trial for 48 weeks, and the collagen/strength trials for 8 weeks. Shilajit is not a quick-fix supplement — it works by optimizing fundamental biological processes that take time to manifest as noticeable changes.

Cycling: There is no clinical evidence that cycling shilajit is necessary. In the longest published trial (48 weeks), benefits continued to accrue without diminishing returns or safety concerns. That said, some practitioners recommend 4–6 weeks on, 1 week off as a general best practice for any adaptogenic supplement.

Shilajit Forms Compared: Resin vs. Tablets vs. Gummies

Shilajit is available in several forms, each with trade-offs. Here is how they compare:

Form | Typical Dose | Onset | Convenience | Best For
Raw Resin | Pea-sized portion (~300–500 mg) | 1–2 weeks | Low — sticky, strong taste, imprecise dosing | Purists who want the "traditional" experience
Tablets / Capsules | 250–500 mg standardized extract | 1–2 weeks | High — precise dosing, no taste, portable | Those who want clinical-grade precision and portability
Gummies | 250–500 mg standardized extract | 1–2 weeks | Highest — enjoyable taste, precise, easy to remember | Anyone who struggles with pill fatigue or wants to enjoy taking their supplements
Powder | 300–500 mg (measured) | 1–2 weeks | Medium — mix into beverages, requires scale for accuracy | Smoothie enthusiasts, those who prefer liquid dosing
Liquid / Drops | Varies widely by concentration | 1–2 weeks | Medium — sublingual absorption possible but taste is strong | Those seeking fast absorption, willing to tolerate strong flavor

The honest take: The form matters far less than the quality of the extract inside it. A well-formulated gummy using purified, standardized shilajit extract delivers the same fulvic acid, DBPs, and minerals as traditional resin — with the massive advantage of precise dosing and a format you will actually take every day. Compliance is the most powerful variable in supplementation. The best shilajit supplement is the one you take consistently.

How to Choose a Quality Shilajit Supplement

The shilajit market is flooded with products of wildly varying quality. Some are genuine; many are not. Here is your filter:

Non-Negotiables

1. Purified extract, not raw resin sold online. Raw shilajit from unverified sources can contain heavy metals (lead, arsenic, mercury), mycotoxins, and other contaminants. Purification removes these while concentrating the bioactive compounds.

2. Standardized to fulvic acid content. Look for a stated fulvic acid percentage (50%+ is ideal). If a product does not tell you how much fulvic acid it contains, that is a red flag.

3. Third-party testing. Certificate of Analysis (COA) from an independent lab, testing for heavy metals, microbial contamination, and active compound verification.

4. Clinical dosage. If the label says "proprietary blend" with no milligram breakdown, move on. You need to know you are getting 250–500 mg of actual shilajit extract per serving.

Green Flags

Sourcing transparency (specific region of origin)

GMP-certified manufacturing facility

Clear identification of the extract type (e.g., "purified shilajit extract" or a named standardized form)

Published or referenced clinical research on the specific extract used

Red Flags

Extremely low prices (quality purification is not cheap)

"100% pure Himalayan shilajit" with no COA or standardization info

Claims of 80%+ fulvic acid (chemically implausible for genuine shilajit)

Sold in unmarked jars or bags with no manufacturer information

Promises of overnight results or "instant" effects

Meru Shilajit Tablets

Safety, Side Effects & Who Should Avoid Shilajit

The safety profile of purified shilajit extract is strong. Across the clinical trials reviewed in this article — spanning 8 to 48 weeks of daily use in diverse populations — no significant adverse effects were reported. Liver and kidney function markers remained within normal ranges. Blood glucose and lipid profiles were unaffected.

The 48-week bone density trial (the longest published shilajit study) specifically monitored safety throughout, with no concerning findings at either the 250 mg or 500 mg daily dose.

Possible Mild Side Effects

Mild digestive discomfort when starting (usually resolves within a few days)

Slight increase in body heat (likely related to metabolic activation)

Headache in rare cases during the first week

Who Should Avoid Shilajit or Consult a Doctor First

People with hemochromatosis (iron overload) — shilajit contains iron and enhances mineral absorption

Those on blood-thinning medications — shilajit may have mild blood-thinning properties

People with active kidney disease — the mineral load may not be appropriate

Those taking blood pressure or diabetes medications — potential for additive effects; medical supervision recommended

Pregnant or breastfeeding women — insufficient safety data in these populations

Children under 18 — not studied in pediatric populations

Critical safety note: Everything above applies to purified, standardized shilajit extract. Raw shilajit from unverified online sources carries real risks of heavy metal contamination, which can cause serious harm. This is not a theoretical concern — it is the primary safety issue with shilajit products. Always choose purified extract from a reputable manufacturer.

Frequently Asked Questions About Shilajit

What is shilajit?

Shilajit is a naturally occurring mineral-rich resin found primarily in the Himalayan mountains. Formed over centuries from the slow decomposition of ancient plant matter compressed between rock layers, it contains over 85 minerals in ionic form, fulvic acid (50–60%), humic acid, and dibenzo-alpha-pyrones (DBPs). It has been used in Ayurvedic medicine for over 3,000 years as a rejuvenator (rasayana) for vitality, cognition, and physical strength. Modern clinical trials now support many of these traditional uses.

What are the main shilajit benefits?

Based on published clinical research, shilajit benefits include: supporting healthy testosterone levels in men aged 45–55 (Pandit et al., 2016), preserving bone mineral density in postmenopausal women (Pingali & Nutalapati, 2022), boosting type I collagen synthesis (Neltner et al., 2023), enhancing mitochondrial energy production and reducing fatigue (Surapaneni et al., 2012), improving sperm quality and male fertility (Biswas et al., 2010), supporting skin health and microcirculation (Das et al., 2019), and maintaining muscular strength during fatiguing exercise (Keller et al., 2019).

How much shilajit should I take per day?

Clinical trials have used purified shilajit extract at 200–500 mg per day, with most positive results at 250–500 mg daily. A typical starting dose is 250 mg per day, taken with food in the morning. After 1–2 weeks, you can increase to 500 mg daily (split into two doses) for maximum benefit. This mirrors the protocols that produced statistically significant results in published research.

What is fulvic acid and why is it important?

Fulvic acid is a low-molecular-weight organic acid that makes up 50–60% of purified shilajit extract. It is the primary driver of shilajit's effects because it acts as a natural molecular carrier: chelating minerals into bioavailable forms, crossing cell membranes to deliver nutrients directly into cells and mitochondria, and functioning as a powerful bidirectional antioxidant. Fulvic acid benefits include enhanced nutrient absorption, reduced oxidative stress, reduced inflammation, and improved cellular hydration.

Are shilajit gummies effective?

Yes, when they contain standardized shilajit extract at clinical dosages. The bioactive compounds (fulvic acid, minerals, DBPs) are the same regardless of delivery format. Gummies actually offer advantages over raw resin: precise dosing (you know exactly how much you are getting), palatability (making daily compliance easy), and stability (protected from oxidation). The key is verifying that the product contains a meaningful dose of purified extract, not just trace amounts for label decoration.

How long does shilajit take to work?

This depends on the outcome you are targeting. Subjective energy improvements are often reported within 1–2 weeks. However, the clinically significant benefits measured in research — testosterone increase, collagen synthesis, bone density preservation, muscular strength retention — were assessed at 8–12 weeks minimum. The bone density trial measured outcomes at 24 and 48 weeks. Plan for at least 8 weeks of consistent daily use before evaluating results.

Is shilajit safe for long-term use?

The longest published clinical trial used shilajit extract daily for 48 weeks (nearly a year) with no significant adverse effects and no concerning changes in liver function, kidney function, blood glucose, or lipid profiles. Multiple shorter trials (8–12 weeks) confirm the safety profile. The key caveat: this applies to purified, standardized extract. Raw shilajit from unverified sources may contain heavy metals and is not recommended for unsupervised use.

Can women take shilajit?

Absolutely. While several studies focus on male-specific outcomes (testosterone, sperm quality), the 48-week bone density trial was conducted entirely in postmenopausal women and showed significant benefits. The skin health and microcirculation trial was also conducted in women. Shilajit's antioxidant, anti-inflammatory, collagen-promoting, and mineral-delivery properties are beneficial regardless of gender. Women who are pregnant or breastfeeding should consult their healthcare provider first.

Can I take shilajit with other supplements?

Shilajit is generally well tolerated alongside other supplements and may actually enhance their absorption due to its fulvic acid content. It has been studied alongside B vitamins for cognitive health applications. However, because it enhances mineral absorption, be cautious about combining with high-dose iron supplements (risk of iron overload). Those taking blood thinners, blood pressure medications, or diabetes medications should consult their doctor before adding shilajit.

What is the difference between shilajit and fulvic acid supplements?

Standalone fulvic acid supplements contain only the fulvic acid fraction, while whole shilajit extract contains fulvic acid plus humic acid, dibenzo-alpha-pyrones (DBPs), DBP-chromoproteins, and 85+ trace minerals. The clinical research showing benefits for testosterone, bone density, collagen, and energy was conducted using whole shilajit extract, not isolated fulvic acid. The compounds in shilajit work synergistically — the DBPs are the direct mitochondrial activators, and the fulvic acid is their delivery vehicle. Removing either diminishes the effect.

The Verdict: Is Shilajit Worth Taking?

Yes — with important caveats.

Shilajit is one of the rare traditional remedies that holds up under modern scientific scrutiny. The clinical evidence base is not enormous, but what exists is promising: multiple randomized controlled trials in humans showing statistically significant benefits across testosterone, bone density, collagen synthesis, muscular strength, fertility, and fatigue resistance.

The mechanism makes biological sense. Shilajit does not work through a single pharmacological pathway — it operates at the level of cellular infrastructure: optimizing mitochondrial energy production, enhancing mineral and nutrient delivery, and reducing the oxidative stress that underlies aging and chronic disease. This explains why its benefits are so broad.

The caveats are straightforward:

1. Quality is everything. The difference between purified, standardized shilajit extract and random resin from an online marketplace is the difference between a clinical tool and a potential health hazard. Do not cut corners here.

2. Patience is required. This is not a stimulant. Give it 8–12 weeks of consistent daily use at an effective dose (250–500 mg) before evaluating.

3. It is not a magic bullet. Shilajit optimizes the biology you already have. It works best as part of a foundation that includes adequate sleep, movement, nutrition, and stress management.

If you meet those conditions, shilajit — whether as a gummy or a tablet — is one of the most well-supported natural supplements available for foundational health optimization.
