Is Nutrition Geeks Lion’s Mane really 4,000mg?

Its official label declares 267mg Lion’s Mane extract at 15:1 per two tablets, described as equivalent to 4,000mg mushroom powder. The 4,000mg is an equivalent figure, not the physical extract weight in the tablets.

Is Nutrition Geeks Lion’s Mane made from fruiting body?

Its official product FAQ says the supplement uses the full fruiting body. Grass & Co. FOCUS capsules also use fruiting-body Lion’s Mane extract.

Does Nutrition Geeks publish testing information?

Its Lion’s Mane product page displays an August 2026 label-accuracy summary attributed to Marfleet Analytical Services for Lion’s Mane extract, B1 and black pepper. That summary should not be interpreted as a published beta-glucan result or a complete contaminant panel.

Does 50% polysaccharides mean 50% beta-glucans?

No. Polysaccharides are a broader category that includes beta-glucans and other carbohydrates. A total-polysaccharide percentage is not a beta-glucan measurement.

Is Grass & Co. stronger than Nutrition Geeks?

We cannot establish that from the labels. Our FOCUS capsules list 600mg of 1:1 extract; Nutrition Geeks lists 267mg of 15:1 extract with a 4,000mg equivalent declaration. Different ratios, formulas and test measures are not evidence of comparative effectiveness.

Do Nutrition Geeks reviews prove health benefits?

No. Customer reviews may be useful for service, convenience and personal preferences, but cannot establish that a supplement causes a health effect. This is a brand-authored label comparison, not a review-score ranking.

Nutrition Geeks reviews: Lion’s Mane labels compared

How does Nutrition Geeks Lion’s Mane Focus+ compare with Grass & Co. FOCUS?

The short answer

Nutrition Geeks Lion’s Mane Focus+ is a two-tablet formula with Lion’s Mane, B1 and black pepper, sold in a 180-tablet pack. Grass & Co. FOCUS is a different blend: Lion’s Mane with Korean Ginseng, algae Omega-3, B12 and D3. The important distinction is dose language: Nutrition Geeks’ 4,000mg headline is a mushroom-equivalent figure, while its label lists 267mg extract. Our FOCUS capsules list 600mg of 1:1 fruiting-body extract. Those numbers do not establish which product is more effective. This is a Grass & Co. label review, not an independent review of Nutrition Geeks’ whole range.

Two tablets versus two capsules — the actual declarations

Two tablets versus two capsules — the actual declarations
Check	Nutrition Geeks Lion’s Mane Focus+	Grass & Co. FOCUS capsules
Daily serving / pack	2 tablets; 180 tablets = 90 servings	2 capsules; 60 capsules = 30 servings
Lion’s Mane extract weight	267mg per two tablets	600mg 1:1 extract per two capsules
Equivalent and ratio	15:1 extract; label declares 4,000mg equivalent mushroom powder	1:1 fruiting-body extract; no 15:1 equivalent headline
Mushroom part	Official product FAQ says full fruiting body	Fruiting body
Other actives	B1 4.4mg (400% NRV); black pepper extract 20mg (10:1)	Korean Ginseng 2,000mg dry herb equivalent; algae Omega-3 90mg providing 9mg DHA; B12 5µg; D3 6µg
Polysaccharides / beta-glucans	Label states 50% polysaccharides; this is not a beta-glucan percentage	Read the published report for the listed FOCUS batch; do not compare it directly with total polysaccharides
Public testing information	Product page displays an August 2026 Marfleet Analytical Services label-accuracy summary for three actives	Listed batch certificates available in the on-page Science reader
Price and supply	90 daily servings per pack; verify the current UK price and delivery at checkout	Listed price £26.50 for 30 servings; retailer offers vary

How to compare value without a misleading “stronger” claim

How to compare value without a misleading “stronger” claim
Question	What to check
Price per day	Divide the total price by daily servings, including delivery. Pack price alone is not a fair comparison.
Extract or equivalent?	Record both separately. A 4,000mg equivalent claim does not mean 4g of extract is in the tablets.
What was tested?	Label accuracy, beta-glucans and contaminants answer different questions. A summary does not establish every test for every batch.
What can it claim?	Check authorised vitamin claims and their conditions. Neither a mushroom-equivalent figure nor customer testimonials prove a treatment benefit.

The trade-offs

Nutrition Geeks

90 daily servings in the listed pack
Clearly separates 267mg extract from 4,000mg equivalent in its ingredient table
Displays a named-laboratory label-accuracy summary
Broader mainstream supplement range

The 4,000mg headline needs the extract-equivalent explanation
Total polysaccharides cannot be read as beta-glucans

Grass & Co. FOCUS

Declared fruiting-body extract amount
Blend includes Korean Ginseng, algae Omega-3, B12 and D3
Listed batch certificates available to read
Capsules, powder, gummies and cans across the FOCUS range

Only 30 daily servings in the capsule jar versus 90 in Nutrition Geeks’ pack
A multi-ingredient blend is not the simplest choice if you only want Lion’s Mane

The verdict

Choose Nutrition Geeks if the long-supply tablet format and its Lion’s Mane/B1/black pepper formula fit your needs. Choose FOCUS if you want our specific mushroom-led blend and access to listed batch reports. Compare price per day and testing scope, rather than treating a bigger equivalent number as proof of a better product.

Where Grass & Co. loses

Nutrition Geeks offers a longer supply in its Lion’s Mane pack and a broader mainstream supplement range. If you only want that tablet formula or a one-stop shop for general vitamins, our smaller, mushroom-led range may not be the best fit. We have no head-to-head trial showing FOCUS outperforms it.
