The short answer
Both use KSM-66 ashwagandha at almost the same dose: 116.7 mg a day in New Leaf and 120 mg in ours. The difference is lion's mane: New Leaf has 40 mg of extract giving 20 mg of polysaccharides, and ours has 500 mg giving 150 mg. New Leaf costs 25p a day and ours 33p.
What we found
- Ashwagandha: both KSM-66, at 116.7 mg and 120 mg a day.
- Lion's mane: 40 mg of extract in New Leaf, 500 mg in ours.
- Polysaccharides: 20 mg a day against 150 mg.
- Price: 25p a day against 33p, checked on 17 October 2026.
- Extras: New Leaf adds a little black pepper extract; ours has none.
What's in each one?
Both are capsules of KSM-66 ashwagandha and lion's mane extract: two a day, 120 to a pack, 60 days' worth. UK law requires each label to give the amount of every active ingredient in a day's dose [1], so here's what each says, with New Leaf first because it comes first alphabetically.
| In a day's dose | New Leaf | Nooroots Ours |
|---|---|---|
| KSM-66 ashwagandha extract | 116.7 mg | 120 mg |
| Withanolides | 5.8 mg (5%) | 6 mg (5%) |
| Lion's mane extract | 40 mg | 500 mg |
| Polysaccharides | 20 mg (50%) | 150 mg (30%) |

How does the ashwagandha compare?
It's almost the same. Both use KSM-66, a root-only extract standardised to 5% withanolides [2]: 116.7 mg a day in New Leaf and 120 mg in ours. That's 5.8 mg and 6 mg of withanolides.
The fronts of the packs differ, at 1,400 mg and 1,800 mg. Those are the extract ratios multiplied out, roughly the amount of root the extracts were made from [3], and they differ because the labels give different ratios, 12:1 and 15:1. The extract you take is about the same.
How does the lion's mane compare?
This is the real difference. New Leaf has 40 mg of a 15:1 extract at 50% polysaccharides, which gives 20 mg a day. Ours has 500 mg of a 10:1 extract at 30%, which gives 150 mg a day.
So ours has 12.5 times the extract and 7.5 times the polysaccharides. New Leaf's extract has a higher percentage, but there's much less of it in each capsule. Neither label says which part of the mushroom is used.
Polysaccharide figures are a rough guide for any brand, because unless the test removes them they also count starch and fillers such as maltodextrin [4].
Which costs less?
New Leaf does. On its own site it was £14.95 for 120 capsules when we checked, down from £16.95, which is 25p a day. Ours is £19.99, or 33p a day. Both packs last 60 days.
New Leaf is also sold more widely: Holland & Barrett, Boots and Tesco list it on their websites, as does Amazon. We sell ours on our own site and on Amazon.
Which should you choose?
- New Leaf if you mainly want KSM-66 ashwagandha for the lowest daily cost, with a small amount of lion's mane. It's also a certified B Corporation, a standard that covers a company's social and environmental record.
- Nooroots if you want the same ashwagandha with a much larger amount of lion's mane, for 8p a day more.
How we compared
- We read New Leaf's label from two images: the nutrition panel on its own site and a photo of the bottle on Amazon UK. Both matched.
- Our figures come from our own pack. Our pack says "ashwagandha root extract"; we've named it KSM-66 from our supplier's documents.
- Prices are for one pack bought once, from each brand's own site, on 17 October 2026, with no subscription or multi-buy.
- New Leaf didn't pay to be included, and we earn nothing from the link to its site. If something here is out of date, tell us and we'll check it.
