What Is a Shilajit Dosage Calculator?

A shilajit dosage calculator tells you how much shilajit to take each day and how to measure it with your own product. Most dose charts online give one number for everyone. Many also add rules for body weight, BMI or lifestyle that no study has tested.

This tool works in a different way. It starts from the amounts adults actually took in published human trials. Then it turns that amount into spoons, capsules, gummies or drops, based on the milligrams printed on your label.

The calculator has two tabs:

• Find my daily amount gives a target for your goal, a gentle start plan and how long your jar will last.
• Check my total intake adds up every shilajit product you take, so you can see if the total is above the tested range.

Shilajit is a dietary supplement, not a medicine. It has not been approved to treat or prevent any disease. The research on it is still small, and most trials had fewer than 100 people.

How to Use the Shilajit Dosage Calculator

1. Enter your age and sex. The tool stops if you are under 18.
2. Pick your main reason for taking shilajit. Each goal links to the trial that tested it.
3. Say whether you are new to shilajit. New users get a lower amount for the first 2 weeks.
4. Tick any health condition or medicine that applies. The tool adds a warning and tells you to check with your doctor.
5. Choose your product form. Type the milligrams of shilajit in one spoon, capsule, gummy, scoop or dropperful. You will find this on the Supplement Facts label.
6. Enter the jar size in grams or the number of servings in the pack.
7. Choose once or twice a day, then read your target, your product amount and your plan.

If your resin came with no milligrams on the label, use our Shilajit Dose Converter first. It turns grams, pea sizes and drops into milligrams.

Take shilajit from more than one product? Open the second tab. Add each product with its milligrams and daily count. The tool shows your total and compares it with the 200 to 500 mg range used in trials.

How Much Shilajit Should You Take Per Day?

Controlled human trials have used 200 to 500 mg of purified shilajit a day. The table shows the five trials this calculator uses. Each one tested a specific goal.

Keep these limits in mind:

• Most of these trials used the same branded, purified extract. Its maker supported several of them.
• Each goal has only one small trial. The results have not been repeated by other teams.
• No trial has tested shilajit for general energy, focus or immunity in healthy people.

One older safety study gave 2,000 mg a day to 20 healthy young volunteers for 45 days. Blood tests showed no harm to the liver or kidneys. But that was one small, short study. It does not show that high doses are safe over months, and no study shows that more than 500 mg works better.

So a sensible plan for most healthy adults is 200 to 250 mg a day to start. Stay at or below 500 mg a day unless a doctor tells you otherwise.

Why This Calculator Does Not Use Body Weight

Many shilajit calculators add milligrams for every extra 10 kg or change the dose for BMI. It looks precise, but no study supports it.

Every human trial gave the same fixed amount to everyone in a group, whatever their weight. No trial compared doses by body size. We also do not know how the body absorbs or clears shilajit, so there is no basis for a mg-per-kg formula.

Adding milligrams for a heavier person could also push the daily amount past 500 mg. That is above the range used in any controlled trial of benefits. For these reasons, this calculator uses your goal and your product, not your weight.

Shilajit Dosage by Form

The same 250 mg can look very different from one product to the next. Always go by the milligrams of shilajit on the label, not the size or weight of the product.

Resin

Most brands include a small spoon and state how many milligrams it holds. A “pea size” is only a rough guide. Resin density varies, so a pea can hold far more or less than you think. For the most accurate dose, use a 0.001 g jewelry scale. 250 mg is 0.25 g.

Capsules

Check the mg of shilajit per capsule, not the capsule weight. A 600 mg capsule may hold only 250 mg of shilajit plus filler. Many capsules hold 500 mg, which is already the top of the trial range.

Gummies and drinks

Gummies often hold 50 to 300 mg of shilajit each, and many list a serving as two gummies. Some list shilajit inside a “proprietary blend” with no amount. In that case you cannot know your dose.

Liquid drops and powder

Drop size depends on the dropper, so use the mg per mL or per dropperful on the label. For powder, level the scoop and follow the stated mg.

Strength also differs between brands. Some list fulvic acid as a percentage. You can compare products with our Fulvic Acid Percentage Calculator. To move a dose between forms, use the Shilajit Dose Converter.

When and How to Take Shilajit

No study has compared morning and evening doses. Here is what the trials did:

• Three trials gave shilajit twice a day. One of them gave it after main meals.
• The other two reported only the daily total.
• All five used capsules of purified extract.

Many people take it in the morning because some feel more alert. If it upsets your stomach, take it with food. If you notice poor sleep, move it earlier in the day.

Resin dissolves well in warm water, tea or milk. Very hot water is not needed. Stir until no pieces remain, so you get the full amount.

How Long Should You Take Shilajit?

The trials ran from 8 to 48 weeks. Most lasted 8 to 14 weeks. The calculator shows the length of the trial for your goal, then suggests a review.

You may read that you must cycle shilajit, for example 6 to 8 weeks on and 1 to 2 weeks off. This advice is common, but no study has tested it. The trials gave shilajit every day without breaks.

A simple approach is to use it for the trial length, then stop and ask yourself whether you noticed a real change. If not, there is little reason to keep paying for it. If you want to use it for many months, talk to your doctor. There is no safety data beyond 48 weeks.

Who Should Not Take Shilajit

In the trials, shilajit was well tolerated and few side effects were reported. But the studies were small and short, so rare side effects may not have shown up. Avoid shilajit, or ask a doctor first, if any of these apply:

• You are under 18. No trial has included children or teens.
• You are pregnant or breastfeeding. There is no safety data, and no one knows if it passes into breast milk.
• You have kidney or liver disease.
• You have prostate problems. One trial found shilajit raised testosterone.
• You use testosterone therapy or other hormone medicines.
• You have high iron levels, since shilajit contains iron and other minerals.
• You take prescription medicine. No drug interaction studies exist, so ask your pharmacist.

Stop and get medical help if you notice a rash, hives, swelling, trouble breathing, dizziness or a fast heartbeat. Allergic reactions are possible with any supplement.

Heavy Metals and Product Quality

Raw shilajit comes from rock. It can contain heavy metals and other impurities if it is not purified. The trials used purified extracts, so their results do not apply to raw or untested products.

This risk is real. A study in JAMA tested Ayurvedic products sold online and found that about 1 in 5 contained lead, mercury or arsenic. The US National Center for Complementary and Integrative Health also warns that some Ayurvedic products contain toxic metals.

Before you buy, check that the brand:

• Shares a recent lab report from an independent lab, with a batch number that matches your jar.
• Tests for lead, arsenic, mercury and cadmium, and shows the results.
• Lists the mg of shilajit per serving, not just a blend.

A higher dose of a poor product is not safer or better. Quality matters more than the number on the spoon.

Common Shilajit Dosing Mistakes

• Reading the capsule or gummy weight as the shilajit amount.
• Taking a gummy and a resin on the same day without adding them up. Use the second tab to check your total.
• Using a “pea size” for resin with no idea of the milligrams.
• Adding extra because of body weight or a heavy workout. No trial supports this.
• Taking more to feel it faster. Trial effects took 8 weeks or more to appear.
• Buying raw resin with no lab report.
