Divide the net weight of the pack by the serving size on the label, and you have the number of servings. Divide that by how often you take it, and you have the number of days. Shilajit resin is sold by weight rather than by count, and packs run from about 10g up to 500g, so the honest answer is arithmetic rather than a single number.
For our resin the serving is 500mg, so a 10g pack is 20 daily servings, a 30g pack is 60, and a 100g pack is 200. If you have resin from somewhere else, use the serving printed on that pack instead — serving sizes are set by each manufacturer and they differ.
How to work out how many servings are in your pack
You need two numbers, and both are printed on the pouch. The first is the net weight of the resin in grams. The second is the serving size, which appears in the directions or the nutrition panel and is usually given in grams or milligrams.
If the serving is stated in milligrams, divide by 1,000 to get grams before you go any further — our 500mg serving is 0.5g. Then it is one division: net weight divided by serving size gives servings per pack. If you take it once a day, servings per pack is also days per pack.
Two things commonly trip people up. Some labels give a range rather than a single serving size, in which case work it out twice and you get the shortest and longest the pack could last. And some people take a serving on training days only, or five days a week, which stretches the pack accordingly.
The method, step by step
The worked example below uses our own 30g pack and our 500mg serving. If your pack is a different size, or from a different brand, substitute your own two numbers.
| Step | What you need | Where to find it | Worked example |
|---|---|---|---|
| 1 | Net weight of the pack, in grams | Front of the pouch or the label | 30g |
| 2 | Serving size, in grams | Directions or nutrition panel | 0.5g (500mg) |
| 3 | Servings per pack | Weight divided by serving size | 30 ÷ 0.5 = 60 |
| 4 | Servings you take per day | Your own routine | 1 |
| 5 | Days per pack | Servings divided by servings per day | 60 days |
| 6 | Months per pack | Days divided by 30, rounded down | 2 months |
Round down at the end rather than up. A little resin always stays behind on the spoon and around the seal of the pouch, so the real figure is slightly shorter than the arithmetic suggests.
Why size comparisons are a poor way to measure resin
Almost every set of directions for resin describes the portion by comparison — usually to a pea or a grain of rice. It is an understandable way to describe something sticky that nobody wants to weigh, but it is imprecise, and for resin specifically it is worse than people assume.
Resin is dense. A piece the size of a grain of rice weighs only a small fraction of a 500mg serving, so anyone following a rice-grain comparison is taking considerably less than the label intends. A pea is much closer to the mark, which is why our own directions use it — but the weight on the pack is the figure that actually counts.
The practical consequence is that two people following the same comparison can take noticeably different amounts, and the same person can drift over weeks without noticing. That is also why estimates of how long a pack lasts vary so much between customers who bought the identical size.
How to be more consistent about your portion
- Weigh it once. A jeweller's scale that reads to 0.01g costs very little. Weigh out 500mg, look at it properly, and you now have a calibrated eye.
- Use a reference object. Once you know what your serving looks like, compare it to something fixed each time — the head of a match, or the tip of the spoon filled to a set point.
- Portion in advance. Some people warm the pouch slightly, divide out a week of small portions, and store them separately. It removes the daily guesswork entirely.
- Use the same spoon. Resin clings to metal, and a consistent tool makes the amount you actually swallow more consistent too.

Picking a subscription interval that matches your pack
Monthly is the default on most subscriptions, and for a small pack taken daily it may well be right. For a larger pack it is usually wrong, and you end up with a shelf of unopened stock and a standing order you resent.
Work out days per pack first, then choose the nearest interval below that figure rather than above it. A 30g pack at 500mg daily is about two months, so a two-month interval fits and a three-month interval leaves a gap. If your pack works out at eight months, most people are better off ordering manually.
It is also worth reviewing after the first pack. Almost everyone takes slightly more than they think they do at the start, so the second one tells you your real rate. You can see the full range of sizes on the shilajit collection and pick one that suits the interval you actually want.
Storing resin so the whole pack stays usable
Shilajit resin is stable stuff and does not need refrigerating. What it does need is a cool, dry, dark cupboard with the pouch sealed properly. Warmth makes it softer and runnier; cold makes it stiff and hard to work with. Both are normal and neither means the resin has spoiled.
Keep water out of the pouch. Wet spoons and steamy bathrooms are the two usual culprits, and moisture is the one thing that genuinely shortens the life of a pack. Use a dry spoon every time, press the seal shut straight away, and keep it out of the bathroom cabinet.
Check the best-before date printed on the pouch. That date assumes the pack is stored as directed and, for a large pack taken slowly, it is worth confirming you will finish it comfortably within it before you buy the biggest size available.
Common questions
Does a bigger pack always work out cheaper per serving?
Usually, but not always, and only if you finish it. Work out the price per gram rather than the price per pack, then check the days-per-pack figure against the best-before date. A large pack you throw a third of away is not a saving.
How do I know how much a serving weighs if the label gives a size comparison?
Look for a weight in grams or milligrams elsewhere on the label — most packs give one in the nutrition panel even when the directions use a comparison. Ours is 500mg. If there is no weight anywhere, weigh a portion yourself on a fine scale. Our guide to reading a supplement label explains where these numbers usually sit.
Do capsules make the maths easier?
Yes. A capsule is a fixed, pre-measured amount, so servings per pot is simply the capsule count divided by the daily number of capsules. That predictability is the main practical difference, and we compare the formats in more detail in resin, capsules or gummies.
Should I take more to finish a pack before its date?
No. Stick to the serving on the label regardless of how much is left. If you consistently have too much resin left over, the answer is a smaller pack or a longer subscription interval next time.
Is there a standard serving size across brands?
There is not. Serving sizes for shilajit are set by each manufacturer, and there is no authorised health claim for shilajit or for fulvic acid in Great Britain, so no official intake figure sits behind them either. Always work from the label in front of you.
