Medical Disclaimer: This article is for information only and is not medical advice. Do not take ashwagandha if you are pregnant, trying to conceive, breastfeeding, under 18 or have a liver condition. Speak to your GP or pharmacist before taking ashwagandha or magnesium if you have a thyroid, kidney or autoimmune condition, take any regular medication (including thyroid, mood, sleep, blood pressure or blood sugar medicines, antibiotics or bisphosphonates), or are due to have surgery. Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle.

Can you take magnesium and ashwagandha together? Yes. They are different things, a mineral and a herb, and we found no reported interaction between them in the published research. The catch is the evidence for the pair: the only randomised trial that gave both in one daily routine (ashwagandha in the morning, magnesium in the evening) found the combined group did no better than the group taking the morning ashwagandha blend alone. So the practical question is dose, not combination. Many combination products shrink one ingredient: one popular US tablet carries 25 mg of ashwagandha, against the 240 to 600 mg a day used in the trials. Our pick is two single products at full label dose: Love Life Supplements Magnesium Glycinate (303 mg elemental magnesium per 4 capsules) and Organic KSM-66 Ashwagandha (600 mg per capsule), about £1.08 a day together. The table below compares six products label by label.

Our figures come from our printed labels. Magnesium Glycinate is unbuffered magnesium bisglycinate in a vegan hypromellose capsule: 2,750 mg of magnesium glycinate gives 303 mg of elemental magnesium per 4-capsule serving (81% of the UK NRV), 60 servings a tub. Organic KSM-66 Ashwagandha is 600 mg of root extract standardised to 5% withanolides (30 mg) in one capsule, 60 servings a tub. CALM, our evening blend, combines 200 mg of KSM-66 with 50 mg of magnesium (as glycinate) per 2 capsules. Prices read live on 6 November 2026: Magnesium Glycinate £37.95 on our UK store and $42.98 on our US store; KSM-66 £26.95 and CALM £29.95, both UK store only. Every tub carries our 60-day money-back guarantee.

Quick takeaways
  • Taking both is fine for most healthy adults: we found no reported interaction, but ashwagandha has its own cautions (pregnancy, liver, thyroid, medication), so check those first.9
  • Only one trial has tested the pair, and the group taking both did no better than the group taking ashwagandha alone over two weeks.1
  • Dose beats combination: ashwagandha trials used 240 to 600 mg of extract a day; the combination products we checked range from 25 mg to 1,200 mg, and their magnesium from 50 mg to 325 mg.
  • Magnesium has authorised health claims, ashwagandha has none. Magnesium contributes to normal psychological function and to the reduction of tiredness and fatigue; no ashwagandha claim is authorised in the UK or EU.15
  • Keep magnesium from supplements at or below 350 mg a day (the US upper limit) or 400 mg (NHS guidance), counting every product you take.13,14

Magnesium and ashwagandha supplements compared: the label table

The table compares the daily serving of six products: our two single-ingredient products taken together, our CALM blend, and three combination products sold in the UK and the US. Every figure for the other brands was read from the brand's own product page or supplement facts panel on 4 November 2026; prices are each brand's one-off price for the pack named, before subscription discounts. Our rows come from our printed labels and live store prices. UK NRV is the 375 mg nutrient reference value for magnesium used on UK and EU labels; ashwagandha has no reference value.

Price per day is the pack price divided by the servings each brand states. Love Life Supplements figures from labels Mag_Bis_P32648_v10, KSM-66_P11383_60x160_v8 and Calm_P15718_60x160v3; prices from our UK and US stores on 6 November 2026.18,19

Two things stand out. First, no combination product gives a full dose of both: the one-tablet product is generous on magnesium and token on ashwagandha, while the KSM-66 blend is the reverse. Second, the cheapest per day (Nutricost, 37 cents) also lands closest to the studied amounts of both, which is worth knowing if you shop in the US and want one product.

Can you take magnesium and ashwagandha together?

Yes. Magnesium is an essential mineral and ashwagandha (Withania somnifera) is a herbal root extract; they work through different routes, and a PubMed search on 4 November 2026 for studies naming both turned up no reported interaction between them. A simple routine is both with an evening meal; the one trial of the pair gave ashwagandha in the morning and magnesium in the evening.

What the research does not show is that the pair does more than either alone. That search returned seven records, and only one was a randomised trial using both in the same routine. Mastrofini and colleagues (2026) gave 103 healthy, physically active adults either a morning capsule (600 mg ashwagandha with 300 mg rhodiola), an evening capsule (2 g magnesium L-threonate supplying 145 mg of magnesium, with 200 mg L-theanine and 50 mg apigenin), both, or placebo, for two weeks.1 The morning ashwagandha group reported lower weekly perceived stress and better subjective sleep quality than placebo; the group taking both did not do better than the morning group, and scored worse on one sleep questionnaire. It was a short trial using blends rather than the two ingredients on their own, so it cannot settle the question, but it is the only direct evidence there is.

That shifts the decision to the label: are you getting a meaningful amount of each, and do you need both? If you only want one, start with magnesium. It is a nutrient with authorised health claims and reference intakes in both markets; ashwagandha is optional.

Magnesium vs ashwagandha: what each one does

Magnesium is the only one of the two with authorised health claims. On the Great Britain register, magnesium contributes to normal psychological function, the normal functioning of the nervous system, normal muscle function, electrolyte balance, normal energy-yielding metabolism and the reduction of tiredness and fatigue.15 No health claim for ashwagandha is authorised in the UK or EU, so no label can promise an effect from it. The table sets the two side by side.

Question Magnesium Ashwagandha
What it is Essential mineral, found in nuts, seeds, beans, wholegrains and leafy greens Root (sometimes leaf) extract of Withania somnifera, a herb used in Ayurvedic tradition
Reference intake UK NRV 375 mg; NHS 300 mg (men) and 270 mg (women); US RDA 310 to 420 mg None: no UK NRV and no US RDA, because it is not a nutrient
Studied supplement dose Commonly 200 to 350 mg elemental a day 240 to 600 mg of root extract a day, usually for 8 to 12 weeks
Authorised health claims (UK and EU) Yes, including psychological function, the nervous system, muscle function and tiredness and fatigue None
Main safety point Loose stools at high doses; kidney disease; spacing from some medicines Rare liver injury reports; possible thyroid effects; avoid in pregnancy; UK safety review in progress

Sources: GB nutrition and health claims register, NHS, NIH Office of Dietary Supplements magnesium and ashwagandha fact sheets, and the trials in the reference list.

The ashwagandha trials, reported as their authors found them and not a promise of any effect: in Chandrasekhar 2012, 64 adults with a history of chronic stress took 300 mg of a root extract twice a day for 60 days and scored lower on stress questionnaires than placebo;2 Salve 2019 compared 250 mg and 600 mg a day for 8 weeks in 60 adults;3 Lopresti 2019 used 240 mg a day for 60 days;4 and a 2021 meta-analysis of five trials (400 people) found a small effect on overall sleep scores, with too little safety data to judge long-term use.5 For magnesium, a 2017 systematic review of 18 studies on subjective anxiety found the evidence suggestive but of poor quality,6 and a review of sleep trials in older adults rated its evidence low.7 No sleep or stress claim is authorised for either.

"Magnesium and ashwagandha are often sold as a pair, but they do different jobs. Magnesium is a nutrient: it contributes to normal psychological function and the normal functioning of the nervous system, and many diets fall short of it. Ashwagandha is a herb with no authorised health claim. I like clients to get their magnesium right first, from food and a clearly labelled supplement, and then decide whether they want the herb at all."

How much magnesium and ashwagandha should you take?

For magnesium, a supplement of about 200 to 350 mg of elemental magnesium a day suits most adults, kept at or below 350 mg from supplements (the US upper limit) or 400 mg (NHS guidance). For ashwagandha, the trials used 240 to 600 mg of root extract a day; follow your product's label and do not stack two ashwagandha products. The reference figures differ by market, so here they are side by side.

Reference UK US
Magnesium need from all sources (adults) NHS: 300 mg a day for men and 270 mg for women aged 19 to 64. Labels use the NRV of 375 mg. NIH ODS Recommended Dietary Allowance (RDA): 400 mg (men 19 to 30), 420 mg (men 31+), 310 mg (women 19 to 30), 320 mg (women 31+)
Magnesium ceiling for supplements NHS: taking 400 mg or less a day from supplements is unlikely to cause any harm NIH ODS Tolerable Upper Intake Level (UL): 350 mg a day from supplements and medicines, not counting food
Ashwagandha No NRV. The Food Standards Agency advises pregnant women and people with liver conditions to avoid it while the Committee on Toxicity completes its review. No RDA or UL. NIH ODS: appears well tolerated for up to about 3 months; long-term safety not known.

Sources: NHS vitamins and minerals guidance; Regulation (EU) No 1169/2011 Annex XIII as retained in GB law; NIH Office of Dietary Supplements magnesium and ashwagandha fact sheets; Which? reporting of FSA advice (June 2026); Committee on Toxicity minutes (September 2026).9,10,11,13,14,16

Two counting traps catch people out. Magnesium turns up in electrolyte drinks, multivitamins and sleep blends, so add up every label before choosing a dose. And "1,200 mg ashwagandha" on one label and "600 mg KSM-66" on another can mean the same 30 mg of withanolides, because the first is standardised to 2.5% and the second to 5%. Compare the withanolide figure where a label gives one. For more on the magnesium side, see how much magnesium glycinate per day.

When to take magnesium and ashwagandha: morning or night?

Take them at whatever meal you will remember every day; neither of our single-ingredient labels sets a time of day. Our Magnesium Glycinate label says to take up to 4 capsules daily with food, and our KSM-66 label says 1 capsule daily with food. Taking both with an evening meal keeps it to one habit, and food makes magnesium kinder to the stomach.

The one trial of the pair gave ashwagandha in the morning and magnesium in the evening, and the ashwagandha trials themselves mostly split the dose between morning and evening. CALM is the exception: its label says to take 2 capsules before bed or in times of stress. If either product leaves you drowsy, move it to the evening. You can also split a 4-capsule magnesium serving, two with breakfast and two with dinner. Our guide to taking magnesium glycinate in the morning or at night goes into timing in more detail.

Magnesium and ashwagandha combination supplement, or two separate products?

For most people, two separate products are the better buy, because you get a full, clearly labelled dose of each and you can stop or change one without losing the other. A combination product makes sense if one capsule or tablet a day matters more to you than the dose of either ingredient.

Look at what each combination actually gives. New Chapter's one-a-day tablet supplies 325 mg of magnesium, a full dose, but 175 mg of it comes from seawater and the chelate is buffered with magnesium oxide, a form absorbed less well in the comparative studies;8 its ashwagandha is 25 mg of an extract that includes aerial parts. Igennus gives a trial-level 600 mg of KSM-66 but 90 mg of magnesium, so you might still want a magnesium supplement beside it. Nutricost's four capsules give 210 mg of bisglycinate and 1,200 mg of a 2.5% extract, the closest of the three to a full dose of both. Our own CALM is built as a wind-down blend of eight ingredients, so it carries smaller amounts of each (200 mg KSM-66, 50 mg magnesium) and is not a substitute for a full magnesium dose.

Which should you choose?

You want magnesium first

A glycinate at 200 to 350 mg elemental, such as our Magnesium Glycinate (303 mg). Add ashwagandha later only if you still want it.

You want both at full dose

Two products: our Magnesium Glycinate plus Organic KSM-66, £1.08 a day. In the US, our magnesium plus a root-only extract from another brand.

You want one evening product

A blend such as our CALM: 200 mg KSM-66 and 50 mg magnesium with L-theanine and botanicals, £1.00 a day.

You want one product at the lowest price

In the US, Nutricost Magnesium + Ashwagandha at 37 cents a day gives 210 mg magnesium and 30 mg withanolides.

Which magnesium is best to take with ashwagandha?

Magnesium glycinate (bisglycinate) is the usual choice, because it is well absorbed, gentle on the stomach at normal doses and easy to take in the evening. Four of the five rows in our table use glycinate in some form, although New Chapter's is buffered and mixed with seawater magnesium. Avoid products built mainly on magnesium oxide if absorption matters to you, and check whether a "chelate" is buffered, which means oxide has been blended in.

Other forms work too: citrate is well absorbed but more likely to loosen stools, and threonate is expensive per milligram of magnesium (2 g supplied 145 mg in the one combination trial). For a form-by-form comparison, see magnesium glycinate vs threonate vs taurate vs malate, or the wider best magnesium supplement guide.

Who should not take ashwagandha or magnesium?

Do not take ashwagandha if you are pregnant, trying to conceive, breastfeeding, under 18 or have a liver condition, and ask your GP or pharmacist first if you have a thyroid or autoimmune condition or take regular medication. Magnesium is the lower-risk of the two, but people with kidney disease should not take it without medical advice.

  • Liver. Rare cases of liver injury have been linked to ashwagandha products, typically with jaundice and itching 2 to 12 weeks after starting; in one case series, liver tests returned to normal within 1 to 5 months.12 In the UK, the Food Standards Agency advises pregnant women and people with liver conditions to avoid ashwagandha while the Committee on Toxicity finishes its safety review, which was still in draft in September 2026.10,11 Denmark banned ashwagandha in food supplements in 2023.9
  • Thyroid. In an 8-week trial in people with subclinical hypothyroidism, 600 mg a day of root extract changed thyroid hormone levels.17 If you take thyroid medication, ask your GP before starting ashwagandha.
  • Medicines. The NIH notes ashwagandha may interact with medicines for thyroid, blood sugar, blood pressure, sleep and mood, and with immunosuppressants.9 Magnesium can reduce the absorption of some antibiotics and bisphosphonates, so take those at a different time of day.13
  • CALM specifically. CALM contains griffonia seed, a natural source of 5-HTP, so do not take it with mood-modifying medication.
  • Use ashwagandha as a course. Most trials lasted 8 to 12 weeks, and the NIH says it appears well tolerated for up to about 3 months, with long-term safety unknown. Review it after a course. Our full guide: is ashwagandha safe?

"Ashwagandha is a herb, not a nutrient, so I think about it differently from magnesium. Before anyone starts it I ask about pregnancy plans, thyroid and liver health and any medication, and I suggest using it for a few months with a review, rather than as something taken indefinitely. Magnesium, at the label dose and with food, is the simpler part of the routine."

How we make and test our magnesium and ashwagandha

All three of our products are made in the UK under GMP. Our Magnesium Glycinate is unbuffered: the only ingredients are magnesium glycinate (bisglycinate) and a hypromellose capsule. Eurofins report AR-733-2026-00087324-03 measured magnesium at 110,000 mg/kg (11%), matching the 11% elemental share printed on the label (303 mg from 2,750 mg). Our KSM-66 is organic, root-only and standardised to 5% withanolides and under 0.1% withaferin A, with a hypromellose capsule as the only other ingredient; batch certificates of analysis are linked from the QR code on every label. CALM's label lists its eight actives with the amount of each per 2-capsule serving.

Prices on a first Subscribe & Save order, read live on 6 November 2026: Magnesium Glycinate £34.16 (UK) or $38.68 (US), KSM-66 £24.26 and CALM £26.96. If you want both in one evening routine, The Wind-Down pairs CALM with our Magnesium Seven.

When ours is not the best choice

  • If you shop in the US and want ashwagandha from us. Our KSM-66 and CALM are not sold on our US store; our Magnesium Glycinate is, at $42.98. Pair it with a root-only extract from another brand, or choose Nutricost's combination.
  • If price per day matters most. Nutricost's combination (37 cents a day) and Igennus on its large pack (51p) cost less than our two products together (£1.08).
  • If you want one capsule a day. Our pair is five capsules a day. New Chapter is one tablet, with a much smaller ashwagandha dose.
  • If you want B vitamins and zinc in the same product. Igennus adds them; ours are single-ingredient by design.

If you do try ours, every tub is covered by our 60-day money-back guarantee.

Frequently asked questions

Can you take magnesium and ashwagandha together?

Yes. Magnesium is a mineral and ashwagandha is a herbal root extract, and we found no reported interaction between them in the published research. The one randomised trial that gave both in a daily routine found the group taking both did no better than the group taking ashwagandha alone over two weeks, so choose each at a meaningful dose rather than relying on the combination. Check the ashwagandha cautions first: pregnancy, liver and thyroid conditions, and regular medication.

Is it safe to take ashwagandha and magnesium every day?

For most healthy adults, daily magnesium at or below 350 mg from supplements (the US upper limit) or 400 mg (NHS guidance) is unlikely to cause harm. Ashwagandha is different: the NIH says it appears well tolerated for up to about 3 months, with long-term safety unknown, so use it as a course and review it. Do not take ashwagandha if you are pregnant, trying to conceive, breastfeeding, under 18 or have a liver condition.

Should I take magnesium and ashwagandha at night?

You can. Neither of our single-ingredient labels sets a time of day; both say to take them with food, so an evening meal works well. The only trial of the pair gave ashwagandha in the morning and magnesium in the evening. If either makes you drowsy, keep it to the evening.

Which magnesium is best to take with ashwagandha?

Magnesium glycinate (bisglycinate) is the usual choice because it is well absorbed and gentle on the stomach at normal doses. Check that the label gives the elemental magnesium and avoid products built mainly on magnesium oxide. Love Life Supplements Magnesium Glycinate gives 303 mg of elemental magnesium per 4 capsules, 81% of the UK NRV.

Is New Chapter Magnesium + Ashwagandha worth it?

It is a convenient one-tablet product with a full magnesium dose (325 mg, part from seawater and part as a buffered bisglycinate chelate), at $17 for 30 tablets on newchapter.com when we checked. Its ashwagandha is 25 mg of an extract that includes aerial parts, far below the 240 to 600 mg of root extract used in the trials. If ashwagandha is the reason you are buying it, a root-only extract at trial dose is the better buy.

Can I take magnesium, ashwagandha and L-theanine together?

Many blends do exactly that, including our CALM and the Igennus product in our table. Check the dose of each ingredient rather than the number of ingredients, and add up magnesium from every product you take. Our guide to combining ashwagandha with other supplements covers L-theanine and other pairings in more detail.
