Shilajit Dosage: How Much to Take, When, and What Form

What Is the Correct Shilajit Dosage?

Getting the dose right with shilajit requires attention to three variables that most supplement guides overlook. First, fulvic acid concentration varies 3–6x between products — a 500 mg capsule from one brand may deliver 10x more active compound than another. Second, the form (resin versus powder versus capsule) changes how the material is measured and absorbed. Third, the only large human RCT used a single proprietary extract (PrimaVie), which means extrapolation to all commercial shilajit products carries uncertainty. The clinical data below provides the best available framework for dosing.

What Doses Were Used in Clinical Trials?

Pandit et al. (2016) used 250 mg of purified shilajit twice daily — 500 mg total per day — for 90 days in 75 men aged 45–55, achieving a 20–23% testosterone increase over placebo (PMID: 26416847). First, the extract was standardized to fulvic acid content using the PrimaVie process. Second, the split-dose protocol (morning and evening) maintained steadier blood levels than single dosing. Third, the 90-day duration suggests shilajit requires 8–12 weeks to produce measurable hormonal effects — shorter protocols may not show results.

Surapaneni et al. (2012) used 25–100 mg/kg in a rat chronic fatigue model, with doses standardized to 56.75% fulvic acid (PMID: 22771318). While not directly translatable to human dosing, the dose-response curve showed benefits across a wide range, supporting the 250–500 mg/day human range as reasonable.

How Should You Dose Each Form of Shilajit?

What Is the Correct Resin Dose?

Resin is the most concentrated form and traditionally considered highest quality, with fulvic acid content typically ranging 60–80% by weight. First, a standard single dose equals a pea-sized portion — roughly 300–500 mg by weight on a digital scale. Second, resin hardens at room temperature and softens with warmth, so briefly warming the container makes portioning easier. Third, dissolve the portion in warm (not boiling) water, milk, or non-caffeinated herbal tea and stir until fully dissolved before drinking. The higher fulvic acid concentration in resin means a smaller physical volume delivers more active compound than powder or capsule forms.

What Is the Correct Powder Dose?

Powder is the easiest form to dose with precision, though standard kitchen utensils lack the resolution needed. First, the target range is 250–500 mg/day — note that 250 mg is approximately 1/16 teaspoon, which is impossible to measure visually with confidence. Second, a milligram-capable digital scale (available for under $20) is the only reliable measurement method for this dose range. Third, a standard 1/8 teaspoon scoop holds approximately 500–600 mg of dense shilajit powder, though this varies by product grind and density.

What Is the Correct Capsule Dose?

Capsule dosing follows label recommendations, but verification matters more with shilajit than most supplements. First, confirm the total shilajit milligrams per capsule (not just serving size). Second, check whether the label states a fulvic acid standardization percentage. Third, verify the product provides a Certificate of Analysis showing heavy metal testing results. Capsules delivering 250–500 mg per serving with stated fulvic acid standardization from a verified source are acceptable.

What Is the Starting Dose Versus Maintenance Dose?

New users should begin conservatively and increase based on tolerance. First, start with 200–250 mg/day as a single morning dose for the first 1–2 weeks to assess gastrointestinal tolerance and rule out allergic response. Second, increase to 500 mg/day (split 250 mg morning and 250 mg evening) once tolerance is confirmed — this matches the Pandit et al. (2016) protocol that produced the 20–23% testosterone increase. Third, published safety data supports doses up to 2 g/day for 45 days and 500 mg/day for up to 48 weeks without serious adverse events (Stohs & Bagchi, 2016; PMID: 26650986). Exceeding 500 mg/day for extended periods without medical supervision increases cumulative heavy metal exposure risk.

When Is the Best Time to Take Shilajit?

Timing depends on the primary goal. First, for energy and mental clarity, take the full dose in the morning on an empty stomach — fulvic acid’s mineral-transport properties suggest improved absorption without food competition. Second, for testosterone support, split dosing (morning and evening with food) mirrors the Pandit et al. (2016) protocol and maintains more consistent blood levels across 24 hours. Third, for exercise recovery, take 250–500 mg approximately 30–60 minutes before training to maximize ATP availability during high-demand periods.

Taking shilajit with food is acceptable if empty-stomach dosing causes gastric discomfort — absorption may decrease slightly but compliance matters more than optimization.

What Should You Look for on a Shilajit Label?

Five label elements separate trustworthy products from questionable ones. First, a stated fulvic acid percentage (20–60% for powder, 60–80% for resin) confirms the manufacturer tested and standardized the batch. Second, the word “purified” indicates the product underwent extraction and filtration to remove rock debris and heavy metal contamination. Third, “standardized to fulvic acid” means batch-to-batch consistency — each container delivers the same active compound concentration. Fourth, a COA (Certificate of Analysis) from a third-party lab is non-negotiable for shilajit given the documented contamination risks. Fifth, specific heavy metal testing (lead, arsenic, mercury, cadmium) below FDA and WHO limits must be verified.

If a product provides no standardization percentage and no COA, there is no way to know what you are actually taking.

Should You Cycle Shilajit?

Cycling shilajit — 8–12 weeks on, 2–4 weeks off — is a common recommendation with limited clinical basis. First, no published study has demonstrated that cycling is required for maintaining shilajit’s effects. Second, some practitioners recommend continuous long-term use, consistent with traditional Ayurvedic practice. Third, the strongest argument for cycling involves limiting cumulative ionic iron and trace mineral load over time, which is a reasonable precaution for otherwise healthy individuals — particularly those who do not monitor serum ferritin regularly. For most users, the 90-day on/2-week off pattern provides a practical balance between consistent benefit and mineral load management.

What Conditions Require Dose Modification?

Several conditions warrant reduced dosing or complete avoidance. First, hemochromatosis or elevated ferritin: avoid shilajit entirely due to bioavailable iron content. Second, gout or elevated uric acid: shilajit may raise uric acid levels and worsen symptoms. Third, hormone-sensitive conditions: lower doses or avoidance, since shilajit affects androgen levels measurably. Fourth, concurrent blood pressure medications: shilajit may lower blood pressure additively — monitor closely if already on antihypertensives. Fifth, diabetes medications: potential additive blood sugar-lowering effect creates hypoglycemia risk — glucose monitoring is required.
