Benefits & Evidence

Shilajit, stress, anxiety and mood

There is no human evidence that shilajit reduces stress or anxiety or improves mood. Shilajit is traditionally described as an adaptogen, a substance said to help the body handle stress, and reviews summarise animal research across several of its proposed effects. No controlled human trial has measured stress, anxiety or mood. Anyone struggling with anxiety or low mood should seek support from a GP or a mental health service.

Animal research and traditional description only; no human trials of stress, anxiety or mood. How ratings work: evidence rating system.

What “adaptogen” means

“Adaptogen” describes a substance said to help the body resist stress. Shilajit has been used as a rejuvenator and an adaptogen in traditional medicine for a very long time.[1] The term isn’t a recognised medical category, and it isn’t measured in clinical trials. Calling something an adaptogen describes a traditional idea; it doesn’t show that the substance reduces stress or anxiety in people.

Traditional descriptionRejuvenator and adaptogen[1]

A 2011 review raised concerns about the doses and controls in some early pharmacological studies of shilajit,[2] which adds to the caution needed with animal findings.

Shilajit and ashwagandha

Shilajit is often sold alongside ashwagandha, another traditional adaptogen, in stress-relief blends. In those products, any calming effect people feel may relate to the other ingredient, and ashwagandha has its own evidence base and safety considerations. Read the label to see what each serving contains; see shilajit vs ashwagandha.

Antidepressants and other medicines

If you take medicines for anxiety or depression

Interactions between shilajit and antidepressants, anti-anxiety medicines or other mental health treatments haven’t been studied. Don’t stop or change prescribed medicines in favour of a supplement, and check with a pharmacist or your prescriber before adding shilajit. See medication interactions.

Getting proper support

If stress, anxiety or low mood is affecting your daily life, a GP can help, and in England you can refer yourself to NHS Talking Therapies for evidence-based treatments such as cognitive behavioural therapy. If you are struggling to cope or feel unsafe, contact your GP urgently, call NHS 111, or call Samaritans free on 116 123, any time. Support is available, and it works.

Why people feel calmer

Many people report feeling calmer after starting a new wellness routine. Taking a few minutes for a warm drink, expecting a benefit, and generally investing in self-care can all improve how people feel. That experience is real, but it isn’t evidence that shilajit itself reduces anxiety; see how reviews can mislead.

Stress and mood claims and UK rules

“Reduces stress” or “supports mood” are health claims that need authorised wording in UK marketing.[3][4] Some nutrients, such as certain B vitamins and magnesium, have authorised claims about normal psychological function; shilajit doesn’t. Claims to treat anxiety or depression are medicinal claims.[5]

Stress, the body and supplements

Stress affects sleep, appetite, energy and mood, which is why so many products promise to help. Approaches with good evidence include regular physical activity, sleep routines, talking therapies, and practical changes to the source of stress where possible. Supplements marketed for stress rarely have trials that measure stress itself, and shilajit has none.

What a convincing stress trial would need

A useful trial would use validated anxiety or stress questionnaires, ideally with objective measures such as cortisol, compare shilajit with placebo for several weeks, and enrol people with a defined level of stress or anxiety. It would also check for interactions in people taking mental health medicines.

Workplace stress

If stress is linked to work, practical changes, conversations with a manager, or occupational health support often help more than products. Many employers also offer confidential support services. If stress is affecting your health, your GP can discuss talking therapies, time off work and other support, and can refer you to services if needed. You don’t need to wait until things feel severe before asking for help.

The bottom line

Shilajit’s calming reputation comes from its traditional description as an adaptogen and from animal research, not from human trials. There is no evidence that it reduces stress, anxiety or low mood in people. Proper support is available through your GP and NHS services, and it has strong evidence behind it.

Frequently asked questions

Does shilajit reduce anxiety?

No human trial has tested this. Claims rest on the traditional “adaptogen” description and animal research.[1][2]

Is shilajit an adaptogen?

It is traditionally described as one,[1] but “adaptogen” isn’t a measured clinical outcome.

Can shilajit help depression?

There is no evidence that it does. Treatment claims are medicinal claims.[5] Please speak to a GP about low mood.

Can I take shilajit with antidepressants?

Interactions haven’t been studied. Check with a pharmacist or your prescriber first.

Is shilajit better than ashwagandha for stress?

No study has compared them, and shilajit has no human stress trials.

Does shilajit lower cortisol?

Not shown in human studies.

Can shilajit help with burnout?

Not studied. Burnout is worth discussing with a GP or occupational health.

Where can I get help for anxiety in the UK?

Your GP, or in England, self-refer to NHS Talking Therapies. If you are struggling to cope, call NHS 111 or Samaritans on 116 123.

Which nutrients have authorised mood claims?

Some, such as certain B vitamins and magnesium, have authorised claims about normal psychological function.[3]

Why do I feel calmer when I take shilajit?

Routine and expectation can improve how we feel; that isn’t evidence that shilajit itself reduces anxiety.
