The mushroom that makes your brain grow. Literally.

Lion's Mane is unlike any other nootropic ingredient. Where most supplements support brain function, Lion's Mane does something more fundamental - it stimulates the production of Nerve Growth Factor (NGF), a protein that promotes the growth and maintenance of neurons. That's not marketing language; it's the mechanism that has made this mushroom the subject of serious neuroscience research for years.

Two independent double-blind, placebo-controlled human trials - Mori et al. (2009) and Saitsu et al. (2019) - both showed meaningful improvements in cognitive function in adults taking Lion's Mane daily. A more recent 2023 pilot study in healthy young adults found faster performance on cognitive tasks following supplementation, alongside a trend toward reduced stress.

Why this particular extract matters

Not all Lion's Mane products are the same, and the difference comes down to two things: the form of extraction and the concentration.

Feel Supreme's extract uses a dual-extraction process - capturing both the water-soluble beta-glucans and the fat-soluble hericenones and erinacines (the active compounds responsible for NGF stimulation). The tincture is 8:1 concentrated, meaning 8kg of raw Lion's Mane goes into every 1kg of extract. In liquid form, absorption is faster and more complete than capsules.

It's also won back-to-back awards - Best Supplement 2021 and Best Healthcare Product 2022, as voted by independent retailers across the UK. That kind of peer recognition means something.

What it supports

Lion's Mane has been studied most extensively for cognitive function - memory, focus, and mental clarity - but its effects extend into the nervous system more broadly. Research has explored its potential in supporting neurological health, reducing anxiety, and improving gut health via the gut-brain axis. It's one of the most genuinely versatile functional mushrooms available.

60ml | 60 servings | 2 months supply

Three pipettes daily, straight or in a drink. Organic. No fillers, no nonsense.

Not suitable for children. Consult your doctor if pregnant, nursing, or taking medications. If you have a mushroom allergy, avoid.

Feel Supreme is a UK brand we've stocked for years and rate highly - their sourcing and extraction standards are well above the industry average, which in the mushroom supplement space matters more than most people realise.
