Shilajit Dosage by Body Weight: The Clinical Range and Our 300–600 mg Formula
Published human trials on purified shilajit use 250–500 mg per day for general wellness, with tested upper limits of 600 mg in athletic and therapeutic contexts. This page shows you the exact dose we recommend for your weight, your goal, and your 20g jar — grounded in those trials, not in influencer copy.
How We Calculate Your Dose
The calculator applies a weight-scaled, goal-modified model. The base, the modifier, and the cap are all visible — no hidden "proprietary" math.
Step 1 — The 300 mg base
Every adult who weighs at or below 60 kg starts at 300 mg per day. This is the lower bound of the clinical range used in our trial write-up on shilajit for men's energy and matches the dose used in the early-stage safety studies on fulvic-acid-standardised shilajit.
Step 2 — Weight scaling (+50 mg per 10 kg over 60 kg)
For every 10 kg of body weight above 60 kg, we add 50 mg. A 70 kg user gets an extra 50 mg. An 80 kg user gets an extra 100 mg. This is intentionally conservative — heavier bodies need more raw material, but they do not need a linear scale-up. The full weight-vs-dose logic is explained in our guide on shilajit dosage by body weight.
Step 3 — Goal modification
Selecting High-Intensity Fitness & Recovery adds an extra 100 mg, reflecting the higher oxidative load and recovery demand documented in shilajit studies on athletes and the 90-day realistic timeline for shilajit effects. The General Wellness and Energy & Cognitive Focus goals stay at the base curve, which is the safer default for first-time users.
Step 4 — The 600 mg cap
No matter the input, the formula hard-caps at 600 mg/day. This is the highest tested dose in published human safety data. Anything above that is unstudied for long-term use, and we will not recommend it. For background on the safety studies, see our breakdown of shilajit side effects and safety.
How to Read Your Result
Your output is more than a number. It gives you three things you can act on immediately:
- Exact mg dose — the precise number to weigh out on a 0.01g scale or measure with the resin scoop we ship.
- Visual size reference — a practical "pea-sized" or "grape-sized" cue, because shilajit resin doesn't come pre-measured.
- Jar longevity — calculated against our standard 20g jar of Kashmiri Himalayan Shilajit, so you know exactly how long your purchase will last.
Pair your dose with our Sugar-Free Kashmiri Kesar Kehwa for a morning ritual that dissolves resin cleanly and adds saffron's crocin for sustained uptake.
What the Evidence Actually Says
Most "shilajit dosage" pages online either copy-paste a single 300–500 mg figure or invent numbers for SEO. We base ours on three sources of evidence:
- Published human trials on purified, standardised shilajit — the same body of research summarised in our science-vs-marketing guide.
- Ayurvedic classical texts, which historically describe shilajit doses in the ratti weight system (≈125 mg increments) — the original "by body weight" framework.
- Our own lab data on the fulvic acid and dibenzo-α-pyrones content of every shilajit batch we ship, which is what actually determines biological activity.
Safety Boundaries You Should Know
This tool is built for healthy adults. It is not a substitute for medical advice. Please read this section before starting.
- Pregnancy & breastfeeding: Shilajit is not recommended. See our pregnancy-specific guide.
- Under 18: The clinical research base is in adults. For context, see our age-related guidance.
- Heavy-metal risk: Unpurified shilajit can contain lead, arsenic, and mercury. Always verify a third-party lab report — here is how to read one.
- Drug interactions: Shilajit can lower blood pressure and blood sugar. See our blood pressure guide and our diabetes guide.
- Autoimmune conditions: Shilajit is immunomodulatory and may not be appropriate. See the related discussion on autoimmune considerations.
How to Take It Properly
Dissolve your measured dose in 100–150 ml of warm liquid — not boiling, since excessive heat degrades fulvic acid. The four carrier options we recommend, in order of effectiveness:
- Warm milk — the classical Ayurvedic carrier. Full-fat is best for resin absorption. Compare with milk vs. water for shilajit.
- Kashmiri Kehwa (sugar-free) — pairs shilajit with Mongra saffron for a daily ritual. The cinnamon and cardamom in our instant mix also help mask the earthy taste.
- Plain warm water — the most neutral option. Less absorption than milk, but better than cold.
- Honey water — works, but only once the water has cooled below 40°C. Heating destroys raw honey's enzymes.
Take it on an empty stomach, 20–30 minutes before breakfast, unless you're dosing around training — in which case 30 minutes pre-workout is optimal. For deeper timing guidance, see morning vs. night shilajit timing and the empty-stomach protocol.
Who This Calculator Is Built For
You will get the most from this tool if you fit one of these profiles:
- You are buying your first jar of shilajit and want a defensible starting dose rather than a guess.
- You already take shilajit but want to verify your current dose is in the safe and effective range.
- You are an athlete or fitness user scaling your dose to body weight and training load.
- You are comparing brands and want to know how long a 20g jar should actually last before you commit.
Why Pair This Tool With Kashmiril Shilajit
Dosage math is meaningless if the shilajit itself is unverified. Every Kashmiril Himalayan Shilajit jar comes with a third-party lab report showing fulvic acid content, heavy-metal absence, and microbial safety. Our 20g resin ships in glass — not plastic — to preserve potency. We also publish why Kashmiri-sourced shilajit is considered the purest form and how it is purified.
Frequently Asked Questions
Is this shilajit calculator accurate?
It is a conservative translation of the published clinical dosage range (250–500 mg) into a body-weight-and-goal formula, capped at the 600 mg safety ceiling. It is not a substitute for personalised medical advice, but it is grounded in the same trials the research community uses. For a deeper breakdown, see our full dosage guide.
Why is the dose capped at 600 mg?
600 mg is the highest tested dose in published human safety studies on purified shilajit. We will not recommend doses above that, regardless of body weight or training load. See our side-effects breakdown for why this matters.
How long will a 20g jar last me?
The calculator divides 20,000 mg by your personalised daily dose. A 350 mg/day user gets 57 days. A 500 mg/day user gets 40 days. A 600 mg/day user gets 33 days. You can also compare resin vs. capsules in our format comparison.
Should I take shilajit every day?
Published human trials run on a daily, uninterrupted protocol. Most practitioners recommend 8–12 weeks of consistent daily use, then reassess. Cycling protocols are also discussed in our cycling guide.
Can I take shilajit with saffron, ashwagandha, or other herbs?
Yes — shilajit is commonly stacked with Kashmiri saffron and ashwagandha, with ashwagandha stacking protocols available for reference.
What is the best time of day to take shilajit?
For most users, morning on an empty stomach, 20–30 minutes before breakfast. For training days, 30 minutes pre-workout. The full timing breakdown is in our timing guide.
Is shilajit safe for everyone?
No. It is not recommended during pregnancy, breastfeeding, or for children, and it can interact with blood-pressure and blood-sugar medications. Read the full safety breakdown before starting.
