Shilajit vs Ashwagandha: Which Is Better, and Can You Take Both?
Love Life Supplements
Reviewed by Sarah Law, Dip CNM, Naturopathic Nutritionist
Shilajit vs ashwagandha: they are not two versions of the same thing. Shilajit is a purified mineral resin, rich in fulvic acid, and its human trials are mostly about men's strength, exercise and testosterone. Ashwagandha is a root extract, and its trials are mostly about stress, sleep and training. So choose by goal: if your main interest is training and vitality in men, shilajit has the closer evidence; if it is feeling stressed or sleeping badly, ashwagandha has far more trials behind it (dozens of placebo-controlled studies against a handful for shilajit). You can take both: no study has tested the pair together, and we found no reported interaction between them, but start one at a time, take both with food, and do not combine either with medication without asking your GP. Our Shilajit Capsules give 600 mg of MEET Shilajeet extract per capsule, and our Organic KSM-66 Ashwagandha gives 600 mg of root extract standardised to 5% withanolides; one of each a day costs £0.98 on our UK store, or £0.88 for a new subscriber.
Our figures come from our printed labels. Love Life Supplements Shilajit Capsules contain 600 mg of a 70:1 shilajit extract (MEET Shilajeet, made from 42,000 mg of raw shilajit) standardised to 60% fulvic acid, in a vegetable cellulose capsule, 60 capsules a tub, 1 to 2 a day with food. The supplier's certificates for two MEET Shilajeet batches (HCFASDE24011/05 and HCFASDE25007/12) show lead of 0.07 and 0.14 ppm against a 3 ppm specification. Our Organic KSM-66 Ashwagandha contains 600 mg of organic KSM-66 root extract per capsule, standardised to 5% withanolides (30 mg) and less than 0.1% withaferin A, 60 capsules, one a day with food. Shilajit is £31.95 on our UK store and $43.32 on our US store (£28.76 and $38.99 for the first Subscribe & Save order); KSM-66 is £26.95 on our UK store (£24.26 first subscription order) and is not sold on our US store. Both are covered by our 60-day money-back guarantee.

View ashwagandha- Different things. Shilajit is a purified mineral resin measured by its fulvic acid; ashwagandha is a root extract measured by its withanolides.
- Different evidence. Shilajit's few human trials centre on men's strength, exercise and testosterone. Ashwagandha has many more trials, mostly on stress, sleep and resistance training.
- Testosterone: a 2024 systematic review of 52 studies rated purified shilajit "possibly effective" for men with low testosterone in later life and ashwagandha "possibly effective" for healthy men. Neither is a proven fix, and most "testosterone boosters" the review looked at did nothing.
- Taking both: no human trial has tested the pair, and we found no reported interaction. Start one, add the second two to three weeks later, both with food.
- Safety: ashwagandha has rare reports of liver injury and is under UK review; shilajit's main risk is raw, unpurified resin carrying heavy metals. Buy purified, batch-tested products.
- Cost: on the six products we checked, a day of shilajit costs $0.40 to £1.07 and a day of ashwagandha £0.33 to £0.45; ours are not the cheapest.
Shilajit vs ashwagandha: the side-by-side comparison
Shilajit and ashwagandha are both Ayurvedic, both sold as "adaptogens", and both get bundled into the same men's health stacks, but almost everything that matters about them is different: what they are, how they are standardised, what their trials measured and who should avoid them. The table puts the two side by side, using the human trials and regulators' positions cited on this page.
| Question | Shilajit | Ashwagandha |
|---|---|---|
| What it is | A blackish brown resin that seeps from rock layers in mountain ranges such as the Himalayas, formed from decomposed plant matter | The root of Withania somnifera, a small evergreen shrub; good extracts use the root only |
| What it is standardised to | Fulvic acid (ours: 60%; others we checked: 20% to 75%, or not stated) | Withanolides (KSM-66: 5%, with less than 0.1% withaferin A) |
| Amounts used in human trials | 250 mg twice a day (purified shilajit), 250 or 500 mg a day, 500 mg twice a day (MEET Shilajeet) | 300 mg of root extract twice a day in most trials cited here; 600 mg once a day on our label |
| What the trials mostly measured | Testosterone in healthy men, strength and fatigue, exercise capacity | Stress scores and cortisol, sleep, strength gains with resistance training, hormones in men |
| Size of the evidence | A handful of small placebo-controlled trials, mostly in men | Dozens of placebo-controlled trials in men and women, several meta-analyses |
| Main safety point | Raw or unpurified resin can carry heavy metals; buy purified, batch-tested extract | Rare liver injury reports; possible thyroid effects; avoid in pregnancy; UK safety review in progress |
| Authorised health claims (UK and EU) | None | None |
Sources: the trials and reviews in the reference list, the NIH Office of Dietary Supplements ashwagandha fact sheet and the UK Committee on Toxicity meeting minutes. Standardisation figures for other brands are from their own labels, read 27 October 2026.
One practical consequence: there are no approved health claims for either ingredient in the UK or EU, so a responsible label cannot promise you more testosterone, lower stress or better sleep. What you can compare is what the label says is in the capsule, what the trials used, and what the batch tests show. That is what the rest of this page does.
Which is better, shilajit or ashwagandha?
Neither is better overall; they suit different goals. Pick shilajit if your interest is training, strength and vitality and you are a man, because that is what its trials studied. Pick ashwagandha if your interest is stress or sleep, or if you want the ingredient with much more research behind it. If you are a woman, ashwagandha has more direct trial evidence, but read the safety section first.
Pick by what you want from it
Shilajit. Its trials gave healthy men 250 to 1,000 mg a day for 8 to 13 weeks and measured strength, fatigue and exercise tests. Ashwagandha also has strength trials, so this one is closer than the marketing suggests.
Ashwagandha. Several placebo-controlled trials of root extract at 600 mg a day reported lower stress scores and, in one, lower cortisol. Shilajit has no comparable stress trials.
Ashwagandha, which has sleep trials using actigraphy and sleep questionnaires. Shilajit has none.
Ashwagandha, by a wide margin. Choose a root-only extract standardised to withanolides, at the trial dose, as a course of 8 to 12 weeks.
If you are looking at shilajit specifically, our shilajit brand comparison and resin vs capsules vs gummies guide go further on formats and purity. For ashwagandha, see the best ashwagandha supplement, seven labels checked.
What does the research show for shilajit?
A few small trials in men suggest purified shilajit can help with strength retention and may raise testosterone modestly, but the evidence is thin and much of it is funded or run by suppliers. These are the human trials most often cited.
- Testosterone, men aged 45 to 55. In a randomised, double-blind trial, healthy men took 250 mg of purified shilajit twice a day for 90 days. Total testosterone, free testosterone and DHEAS rose significantly compared with placebo, and the hormones that signal the testes (LH and FSH) stayed steady.1
- Strength and fatigue, younger men. Sixty-three recreationally active men took 250 mg, 500 mg or placebo a day for 8 weeks. Overall the groups did not differ, but among the stronger half of the men, those on 500 mg lost less strength during a fatiguing leg test (8.9%) than those on 250 mg (17.0%) or placebo (16.0%).2
- MEET Shilajeet, the extract in our capsules. Fifty healthy men aged 18 to 45 took 500 mg twice a day or placebo for 60 days alongside an exercise programme. The shilajit group did better on push-ups (22.6 vs 16.5), squats (34.9 vs 25.9) and estimated VO2max (68.8 vs 58.8 ml/kg/min). Average testosterone rose from 4.69 to 5.06 ng/mL against a slight fall on placebo, a 10.6% difference that did not reach statistical significance.3 Two of the four authors work for Herbal Creations, which makes MEET Shilajeet, and the journal is not indexed in PubMed, so read it as early, supplier-led evidence.
A 2024 systematic review of 52 studies of so-called testosterone boosters found that most did not raise total testosterone. It rated purified shilajit as "possibly effective" for men with late-onset hypogonadism (low testosterone in later life), based on a small number of studies.4 That is a fair summary of where shilajit stands: interesting, plausible, not settled. Our full read of the testosterone trials is in can shilajit boost testosterone?
What does the research show for ashwagandha?
Ashwagandha root extract has a much larger body of placebo-controlled trials, most of them in stressed adults, poor sleepers or men in resistance training, and most using 600 mg a day. The best known:
- Stress. Sixty-four adults with chronic stress took 300 mg of a high-concentration, full-spectrum root extract twice a day for 60 days. Scores on every stress questionnaire fell significantly compared with placebo, serum cortisol was substantially lower, and side effects were mild and similar in both groups.5
- Sleep. Sixty adults with insomnia and anxiety took 300 mg of root extract twice a day or placebo for 10 weeks. Measured by a wrist sleep monitor, the time taken to fall asleep was shorter on ashwagandha (29.0 vs 33.9 minutes) and sleep efficiency improved.6
- Strength training. Fifty-seven young men new to resistance training took 300 mg twice a day or placebo for 8 weeks. Bench press strength rose by 46.0 kg against 26.4 kg on placebo, leg extension by 14.5 kg against 9.8 kg, and testosterone rose by 96.2 ng/dL against 18.0 ng/dL.7
- Men aged 40 to 70. In a 16-week crossover trial, overweight men with mild fatigue took an ashwagandha extract (21 mg of withanolide glycosides a day) for 8 weeks. Testosterone rose 14.7% more and DHEA-S 18% more than on placebo, but fatigue, vigour and sexual wellbeing did not differ between the groups.8
The same 2024 review rated ashwagandha "possibly effective" for raising testosterone in healthy men, from three studies.4 On the hormone question the two ingredients sit at a similar, modest level of evidence; on stress and sleep, ashwagandha is the only one of the two with trials at all.
Shilajit vs ashwagandha for testosterone: which has better evidence?
They are roughly level, and neither is strong. Each has two or three small trials in men reporting a rise in testosterone against placebo, and the 2024 systematic review rated both "possibly effective" in particular groups of men, not proven.4
If testosterone is your real concern, the more useful step is a blood test through your GP or doctor, because low testosterone has causes a supplement will not touch, and the trials above were in men whose levels were broadly normal or mildly low. Sleep, body fat, alcohol and training matter more than either capsule.
Can you take shilajit and ashwagandha together?
Yes, most healthy adults can, but no human trial has tested the two together, so nobody can tell you the combination works better than either alone. We searched PubMed on 27 October 2026 and found only animal studies and multi-herb formulas containing both; we found no published report of an interaction between them. They are often sold together in "stack" gummies alongside sea moss and tongkat ali, usually at doses well below the trials.
If you want to try both, these are sensible ground rules:
- Start one at a time. Take one for two to three weeks before adding the other, so you can tell which one is behind any change in sleep, digestion or energy.
- Take both with food. Both of our labels say so: one KSM-66 capsule a day with food, and 1 to 2 shilajit capsules a day with food.
- Keep to the label. Combination products that add several herbs at once make it harder to know what you are taking; two single-ingredient products at known doses are easier to judge.
- Check medication first. Ashwagandha may interact with medicines for thyroid, blood sugar, blood pressure, sleep and mood, and immunosuppressants, according to the NIH Office of Dietary Supplements.9 Ask your GP or pharmacist before adding either.
- Use it as a course. Most ashwagandha trials lasted 8 to 12 weeks and the NIH notes it appears well tolerated for up to about 3 months, with long-term safety unknown. Review after a course rather than taking it indefinitely.
"When a client wants to take both, I suggest starting with one and adding the second two or three weeks later, each with a meal. That way, if your sleep, digestion or energy changes, you know which one it came from, and you can decide whether you really need the pair."

Shilajit and ashwagandha products compared by label and price
We read the label of three shilajit products and three ashwagandha products, including ours, on 27 October 2026. The table shows what one serving contains, what it is standardised to and what a day costs at the brand's own one-off price. Products are sold in different markets, so prices are shown in the currency of the store we read them from.
| Product | Per serving (label) | Standardised to | Servings and price | Cost per day |
|---|---|---|---|---|
| Love Life Supplements Shilajit Capsules | 1 capsule: 600 mg shilajit 70:1 extract (MEET Shilajeet, from 42,000 mg); 1 to 2 capsules a day with food | 60% fulvic acid (360 mg a capsule, our arithmetic) | 60 capsules: £31.95 / $43.32 | £0.53 / $0.72 (1 capsule); £1.07 / $1.44 (2) |
| Trace Minerals Shilajit Capsules | 2 capsules: 1,000 mg shilajit extract 20:1 plus 25 mg ConcenTrace trace minerals | 200 mg fulvic acid a serving (20%) | 75 servings (150 capsules): $29.99 | $0.40 |
| Lotus Blooming Herbs Authentic Shilajit (resin) | 100 mg purified resin (a rice-grain portion), 1 to 3 times a day | Not stated on the label | 100 servings (10 g tin): $59.99 | $0.60 (once a day) to $1.80 (3 times) |
| Love Life Supplements Organic KSM-66 Ashwagandha | 1 capsule: 600 mg organic KSM-66 root extract; HPMC capsule only | 5% withanolides (30 mg); less than 0.1% withaferin A | 60 capsules: £26.95 (UK store only) | £0.45 |

Sources: traceminerals.com, lotusbloomingherbs.com, nutravita.com and nutricost.com product pages and supplement facts images, read 27 October 2026; one-off prices before subscription or bundle discounts. Our figures are from our printed labels (Shilajit_157x52 v6, KSM-66 P11383 v8) and our live store prices. Cost per day is pack price divided by servings at the label's own serving. We have not converted any currency.
Three things stand out. First, shilajit labels are hard to compare: one gives an extract ratio and a fulvic acid percentage, one gives fulvic acid in milligrams, and the resin tin gives neither. Fulvic acid content is the closest thing to a common measure, and on that basis two of our capsules (720 mg fulvic acid) carry more than a serving of the Trace Minerals capsules (200 mg). Second, ashwagandha labels are easier, because KSM-66 is a branded extract with a fixed specification, so 600 mg of KSM-66 from any brand is broadly the same ingredient. Third, ours are not the cheapest: Nutricost's KSM-66 is $0.28 a day and Nutravita's £0.33, and Trace Minerals' shilajit is $0.40 a day.
How much shilajit and ashwagandha should you take?
Follow the label, which for most products sits close to the trials: about 250 to 1,000 mg of purified shilajit a day, and about 600 mg of ashwagandha root extract a day. Neither has an official daily intake in either market, because they are botanicals, not vitamins or minerals.
| Ingredient | UK reference | US reference | Amounts in trials | Our label |
|---|---|---|---|---|
| Shilajit | No NRV (not a vitamin or mineral); NHS general advice on herbal products applies | No RDA; no NIH ODS fact sheet | 250 mg twice a day; 250 or 500 mg a day; 500 mg twice a day | 600 mg extract, 1 to 2 capsules a day with food |
| Ashwagandha | No NRV; Food Standards Agency advises pregnant women and people with liver conditions to avoid it during the UK review | No RDA; NIH ODS: appears well tolerated for up to about 3 months, long-term safety unknown | 300 mg root extract twice a day in most trials cited | 600 mg KSM-66, 1 capsule a day with food |
UK NRVs exist only for vitamins and minerals (Regulation 1169/2011, Annex XIII). NIH ODS position from its ashwagandha health professional fact sheet; FSA position as reported during the Committee on Toxicity review (see the safety section).
On timing, neither label sets a time of day. Many people take ashwagandha in the evening because of the sleep trials and shilajit in the morning, but the trials gave both in split doses through the day, so pick a meal you will not forget.
Who should not take shilajit or ashwagandha?
Pregnant or breastfeeding women, under-18s, and anyone with a liver condition should not take ashwagandha, and the same caution is sensible for shilajit, which has no safety data in those groups. Anyone with a thyroid or autoimmune condition, or taking regular medication, should ask their GP first.
Ashwagandha
Most people in trials report no more than mild stomach upset or drowsiness. The concern is rare liver injury: a 2020 case series described five people who developed jaundice 2 to 12 weeks after starting ashwagandha supplements; none had liver failure and liver tests returned to normal within 1 to 5 months in the four who were followed up.10 The NIH Office of Dietary Supplements also notes possible effects on thyroid hormones.9 In the UK, the Committee on Toxicity discussed a third draft statement on ashwagandha's safety in September 2026, and it had not been published when we checked.11 Denmark banned ashwagandha in food supplements in 2023.9 Our full guide is is ashwagandha safe?
Shilajit
The main risk is the product, not the ingredient: raw or poorly purified resin can carry lead, arsenic and other heavy metals. UK and EU law sets maximum levels for food supplements of 3.0 mg/kg for lead, 1.0 mg/kg for cadmium and 0.10 mg/kg for mercury.12 Ask any brand for a certificate of analysis with measured numbers, not just "complies". Who else should be careful is covered in who should avoid taking shilajit.
The NHS says herbal products should not be taken if you are pregnant or breastfeeding, have kidney or liver problems, or take certain medicines, and that they are not recommended for children.13
"Before either of these, I ask about three things: pregnancy or trying to conceive, thyroid or liver history, and any regular medication. If the answer to any of them is yes, the conversation goes to the GP first. For everyone else, I see both as a course with a review date, not something to take forever without checking in."

How we check our shilajit and ashwagandha
Both products are made in the UK under a GMP licence and come with batch certificates on their product pages. The shilajit certificates are the supplier's analysis of the MEET Shilajeet extract; the ashwagandha certificate is the manufacturer's release check on finished capsules.
| Product and batch | Checked by | Heavy metals | Other results |
|---|---|---|---|
| MEET Shilajeet extract, batch HCFASDE24011/ |
Herbal Creations (supplier certificate) | Lead 0.07, cadmium 0.16, arsenic 0.13, mercury 0.04 ppm; total heavy metals 1.47 ppm | Identity by TLC complies; loss on drying 3.42% |
| MEET Shilajeet extract, batch HCFASDE25007/ |
Herbal Creations (supplier certificate) | Lead 0.14, cadmium 0.18, arsenic 0.08, mercury 0.05 ppm; total heavy metals 1.48 ppm | Identity by TLC complies; loss on drying 2.73% |
| Organic KSM-66 Ashwagandha capsules, batch 66500213 (made 22 July 2026) | UK manufacturer release certificate | Conforms to lead max 3 ppm, cadmium max 1 ppm, mercury max 0.1 ppm, arsenic max 1 ppm | Microbiology conforms (E. coli under 10 cfu/g, Salmonella not detected in 25 g); fill weight conforms |
From the certificates of analysis linked on our shilajit and ashwagandha product pages, read 27 October 2026. ppm is the same as mg/kg. The ashwagandha certificate reports pass or fail against limits rather than measured values. More on our approach is on our testing page.
Where Love Life Supplements is not the best choice
We sell both products on this page, so here is where another option may suit you better.
- Lowest price. Nutricost KSM-66 ($0.28 a day) and Nutravita KSM-66 (£0.33) cost less than ours (£0.45). For shilajit, Trace Minerals capsules cost $0.40 a serving against our $0.72 for one capsule.
- Resin. If you want shilajit in its traditional resin form, ours is a capsule. Resin is harder to dose, so choose one with a published heavy metal test.
- Ashwagandha in the US. Our KSM-66 is sold on our UK store only. US readers can buy our Shilajit Capsules from our US store.
- Sport testing. Neither of our products is certified by a sport anti-doping programme. If you are tested in competition, choose a product certified by Informed Sport or NSF Certified for Sport.
Frequently asked questions
Is shilajit or ashwagandha better?
Neither is better for everyone. Shilajit's trials focus on men's strength, exercise and testosterone; ashwagandha's focus on stress, sleep and strength training, and there are many more of them. Choose shilajit for training and vitality in men, ashwagandha for stress or sleep or if you want the larger body of evidence.
Can you take shilajit and ashwagandha together?
Most healthy adults can. No human trial has tested the pair and we found no reported interaction between them. Start one, add the other two to three weeks later, take both with food at the label dose, and ask your GP first if you take any medication or have a thyroid, liver or autoimmune condition.
Which is better for testosterone, shilajit or ashwagandha?
The evidence is similar and modest for both. A 2024 systematic review of 52 studies rated purified shilajit "possibly effective" for men with low testosterone in later life and ashwagandha "possibly effective" for healthy men, while most other "testosterone boosters" did not work. If you are worried about low testosterone, a blood test through your doctor is the first step.
Is shilajit or ashwagandha better for stress?
Ashwagandha. Several placebo-controlled trials gave stressed adults 600 mg of root extract a day and reported lower stress scores, and one found lower cortisol. Shilajit has no comparable stress trials in people.
Should I take shilajit and ashwagandha in the morning or at night?
Neither label sets a time, only that you take them with food. Many people take shilajit with breakfast and ashwagandha with an evening meal, but the trials split doses through the day, so the best time is a meal you will remember.
How long do shilajit and ashwagandha take to work?
The trials ran for 8 to 13 weeks, and most measured results at the end, so judge either one after about two months of daily use. The NIH notes ashwagandha appears well tolerated for up to about 3 months and its long-term safety is unknown, so review it after a course.
