The picks in detail

Best overall Nooroots Ashwagandha + Lion's Mane Ours

The top score of the 13, three points ahead. It has the joint second-most lion's mane extract, 500 mg of fruiting body extract with 150 mg of polysaccharides a day, with 120 mg of KSM-66 alongside. It costs 33p a day with free delivery, has 244 reviews averaging 4.65, and its 60-day money-back guarantee covers an opened pouch.

Runner-up OMNIA Lion's Mane Advanced with Ashwagandha

Second, on price and its label. At 10p a day it costs least of all, with free delivery from Amazon, and the label gives every figure, fruiting body included. 125 Amazon reviews average 4.5. The amounts are small: 100 mg of ashwagandha extract (7 mg withanolides) and 133.4 mg of lion's mane extract a day, in tablets.

Best value Horbäach KSM-66 Ashwagandha & Lion's Mane Complex

The lowest cost a day after OMNIA, at 12p. For that you get 140 mg of KSM-66 and 110 mg of lion's mane extract, and 120 Amazon reviews averaging 4.3.

Strongest doses The Buzz! Boom Lion's Mane + Ashwagandha KSM-66

The most of both: 600 mg of KSM-66, which works out at 30 mg of withanolides, and 1,000 mg of fruiting body extract. That takes three capsules a day, and with delivery a 30-day pack costs 90p a day, so it scores low on price.

Best tablet Prowise KSM-66 Ashwagandha & Lion's Mane Tablets

The best-scoring tablet after OMNIA: 15p a day with free delivery, and 60 reviews averaging 4.65. The amounts are modest, at 125 mg of KSM-66 and 46.7 mg of lion's mane extract.

The other eight

Missing out on a pick doesn't mean missing the point. Here are the rest in score order, with what sets each one apart.

• 70

  New Leaf Ashwagandha KSM-66 & Lion's Mane

  4.8 from 315 reviews on its own shop, free delivery, a money-back guarantee and 25p a day, but light amounts: 116.7 mg of KSM-66 and 40 mg of lion's mane extract.

• 59

  Neo-Nutrition Ashwagandha KSM-66 & Lion's Mane Complex

  The same amounts as Free Soul's tablets, 250 mg of KSM-66 and 417 mg of fruiting body extract, in capsules for 30p a day. One review so far.

• 55

  UKHealthHouse KSM-66 Ashwagandha & Lions Mane with Black Pepper

  The same amounts as New Leaf for 14p a day with free delivery, but no reviews on its shop.

• 52

  NobleNature Ashwagandha KSM-66 4-in-1 with Lion's Mane

  Good amounts of both and every figure on the label, but £1.99 delivery, returns for unopened packs only and no reviews on the page.

• 50

  Free Soul Ashwagandha KSM-66 + Lion's Mane

  250 mg of KSM-66 and 417 mg of fruiting body extract in tablets, with £2.99 delivery and four reviews.

• 49

  Nootro Labs Ashwagandha & Lion's Mane + B Complex

  127 Amazon reviews averaging 4.4, but the label doesn't say how much of either extract you take.

• 42

  Kratox Ashwagandha & Lion's Mane

  500 mg of each extract, and the dearest a day at £1.03 with delivery.

• 33

  Love Mushrooms Focus: Lion's Mane + Ashwagandha

  The most ashwagandha extract, 800 mg, at 1.5% withanolides (12 mg). £4.25 delivery and no reviews on its page.

What's on each label

These are the amounts in one day's dose, as each label sets it. Love Mushrooms has the most ashwagandha extract, 800 mg, but at 1.5% withanolides that's 12 mg; The Buzz!'s 600 mg at 5% works out at 30 mg. Six name the fruiting body, the mushroom's cap and stem; the rest don't say which part.

Two pairs with the same label

Free Soul and Neo-Nutrition list the same amounts in the same order. So do New Leaf and UKHealthHouse. We can't tell from the labels whether each pair comes from the same maker, so each has its own row. If you like one of a pair, it's worth checking the other's price.

New Leaf's has almost the same amount of KSM-66 as ours, so we've compared the two in Nooroots vs New Leaf: what's on the label.

What to look for on the label

The front of a pack is the advert and the panel on the back is the facts. Three things on that panel do most of the work.

The extract amount, not the big number

Most packs lead with a figure like "5,000 mg". That's the extract ratio multiplied out: roughly how much dried root or mushroom went into the extract, not how much you take [1]. Think of a juice carton that tells you how many oranges went in, not how much juice is inside. Ours does it too: "5,000 mg lion's mane" stands for the 500 mg of extract in a day's dose. UK labels must also give the amount in a day's dose [2], and that's the figure to compare.

Withanolides, for ashwagandha

Withanolides are the compounds ashwagandha extracts are measured by [3]. Multiply the extract by its percentage: 600 mg at 5% gives 30 mg. KSM-66 is a root-only extract standardised to 5% [4].

The part and the polysaccharides, for lion's mane

Look for the part used and a polysaccharide or beta-glucan figure. Polysaccharide figures are a rough guide, because unless the test removes them they also count starch and fillers such as maltodextrin [5]. That matters most for mycelium grown on grain, which leaves a lot of grain in the product [6]. Beta-glucans are a narrower measure.

The fruiting body and the mycelium are richer in different compounds [7], and no published trial has compared them, so neither part has been shown to be better.

How we scored

Every product was scored by the same rules, ours included. Each measure is scored against the rest of the 13, not against a target. For the amounts used in published studies, see our research pages on ashwagandha studies and lion's mane studies.

• Ingredient amounts (25 points). Half for withanolides a day against the most of the 13 (30 mg), half for lion's mane extract a day against the most (1,000 mg). Where a label names KSM-66 but no percentage, we used KSM-66's own 5% [4]. An amount the label doesn't give scores nothing.
• Price a day (20 points). One pack bought once, plus its delivery, divided by the days it lasts. The cheapest a day scores 20, the dearest 0 and the rest in between. Where a shop had a sale on, we used the sale price.
• Label transparency (20 points). Five points each for giving both amounts, the withanolides, the part of the mushroom, and the polysaccharides or beta-glucans.
• Customer reviews (15 points). Up to 7.5 for how many reviews the product page shows, and, from 20 reviews up, up to 7.5 for the average: 4.0 or lower scores nothing and 4.8 or higher scores in full. Trustpilot scores for a whole shop don't count, because they aren't about the product.
• Delivery and returns (10 points). Five for free delivery on one pack. Five for a money-back promise that covers an opened pack, or 2.5 for returns of unopened packs only.
• Ease of use (10 points). Up to 4 for the number a day (two or fewer scores in full), up to 3 for how long a pack lasts (60 days or more scores in full) and 3 for vegan, or 1.5 for vegetarian.
• The picks follow fixed rules: best overall and runner-up are the top two scores, best value is the lowest cost a day, strongest doses has the most withanolides and lion's mane extract, and best tablet is the top-scoring tablet. Each product takes one pick; where a pick's leader already has one, it goes to the next in line.

We included every capsule or tablet on sale in the UK that we could find on 17 October 2026 whose two main ingredients are ashwagandha and lion's mane; vitamins, minerals and black pepper were fine, other herbs weren't. We read each label panel and went with it where the website said something different, and we checked delivery charges at each shop's checkout. For the four sold on Amazon we used the one-time price, not Subscribe & Save, and Amazon's free delivery on a first order. We left out Liekoh, which is sold only in the US and adds other herbs, and OQO, which we couldn't find on sale. Our pack says "ashwagandha root extract" and doesn't name the mushroom part; we've named KSM-66 and the fruiting body from our suppliers' certificates of analysis, which we keep on file rather than publish.

No brand paid to be included, and we earn nothing from links to other brands. If something here is out of date, tell us and we'll check it.

Frequently asked questions

Can you take lion's mane and ashwagandha together?

Yes. No interaction between them is known, though no published trial has tested the pair. Our guide to taking lion's mane and ashwagandha together covers timing and who should check with a GP first.

What are withanolides?

They're natural compounds found in ashwagandha, and extracts are standardised to a set percentage of them [3]. The percentage tells you how concentrated an extract is.

What percentage of withanolides should ashwagandha have?

There's no set figure. KSM-66 is standardised to 5%, and the other extracts in a 2026 review of trials used 1.5% to 2.5% [4]. Another counts a different group of compounds, at 35% [8], so check what a percentage measures, then compare the milligrams in a day's dose.

How many withanolides should you take a day?

There's no official amount. Most trials of KSM-66 in healthy adults used 600 mg a day, which at 5% is 30 mg [4]. Follow the dose on your product's label.

Can you take lion's mane with ashwagandha and magnesium?

No interaction between the three is known. If you add magnesium, the NHS says 400 mg a day or less from supplements is unlikely to cause harm [9]. Our guide to how much magnesium to take has more.

Is New Leaf ashwagandha good?

Its ashwagandha is KSM-66, at 116.7 mg a day with 5.8 mg of withanolides, alongside 40 mg of lion's mane extract. We've compared it with ours in Nooroots vs New Leaf.
