How long to take shilajit before it works

Shilajit isn’t something the research suggests you’ll feel after a dose or two. Every trial gave it daily for weeks or months and measured changes at the end, so the realistic question is how many weeks to give it before deciding whether it’s worth carrying on. Based on the trials, that’s 8 to 12 weeks for most goals, and longer for slow-changing things like bone.

How long you can safely keep going is less certain. The longest trial lasted 48 weeks. Beyond that there’s simply no data, which is different from evidence of harm, but worth knowing before you commit to years of use.

How long did shilajit trials last?

Between 28 days and 48 weeks. Most ran for 8 to 14 weeks.

How long does shilajit take to work?

It depends on what you’re hoping for, and on which trial you look at:

• Within a month: the resin study reported better strength and lower fatigue scores after 28 days (Yadav et al., 2026). With no placebo group and authors from the manufacturer, it can’t show that shilajit caused the change.
• Around 8 weeks: the strength and collagen trials found differences from placebo at 8 weeks (Keller et al., 2019; Neltner et al., 2024), and muscle gene changes were measured at 8 weeks (Das et al., 2016).
• Around 3 months: the testosterone and sperm trials measured results at 90 days (Pandit et al., 2016; Biswas et al., 2010).
• Six months or more: in the bone trial, blood markers of oxidative stress had changed by week 12, but bone density differences were reported at 24 and 48 weeks (Pingali and Nutalapati, 2022). Bone changes slowly, so a long trial was needed to see anything.

These are the points at which researchers chose to measure, not the moment the effect began. A trial that measured only at 90 days can’t tell us whether something changed at 30.

Fracture healing is a special case. In the Sadeghi et al. (2020) trial, 160 adults took 1,000 mg or placebo for 28 days after tibia surgery. Average time to bone union was 129 days with shilajit against 153 days with placebo, so a short course was followed by a difference months later.

Can I take shilajit long term?

We can only say it has been taken daily for up to 48 weeks in a trial. The Pingali and Nutalapati (2022) trial in 60 postmenopausal women is the longest, and its abstract doesn’t report on side effects. Shorter trials reported few problems: liver and kidney tests didn’t change over 90 days (Biswas et al., 2010), no adverse effects were reported over 14 weeks (Das et al., 2019), and side effects were no more common than on placebo in the fracture trial (Sadeghi et al., 2020).

We found no published data on use beyond about a year. If you plan to take shilajit for longer, the main thing you can control is contamination: low-metal, batch-tested products keep cumulative exposure down. See shilajit side effects and shilajit and heavy metals.

Should I cycle shilajit or take breaks?

There’s no evidence either way. You’ll see “cycling” schedules online, such as weeks on and weeks off, but no trial has compared continuous use with breaks. Every trial gave shilajit continuously for its full length.

A planned break can still be useful, for a different reason: it’s the simplest way to find out whether shilajit is doing anything for you. If you feel no different after stopping, that’s useful information.

What happens when you stop taking shilajit?

We don’t know. We found no trial that followed people after they stopped to see whether changes lasted or faded, or whether stopping caused any effects of its own. The fracture trial is the closest, since the benefit appeared after the 28-day course ended, but that’s a one-off healing process rather than an ongoing effect.

How do I decide whether shilajit is working for me?

Decide what you’re looking for before you start, and set a review date:

1. Pick one goal and a way to track it, such as a training log, a fatigue score you note each week, or a blood test your GP already does.
2. Use a trial dose of 250 to 500 mg a day. See shilajit dosage.
3. Give it 8 to 12 weeks, taken at consistent times. See the best time to take shilajit.
4. Review honestly. If nothing has changed, stopping is reasonable. Bear in mind that how strong the evidence is varies a lot between claims; our evidence grades explain how we rate each one.
