How Lion's Mane Works

The Science Of Staying Sharp, In Plain Language

Lion's Mane has been studied for one reason: it appears to support the brain's own repair machinery. Here's the simple version.

Feeds your neurons

Hericenones & erinacines support Nerve Growth Factor (NGF), the protein that maintains and repairs brain cells.

Standardized beta-glucans

Every dose delivers a consistent, clinically relevant amount of the active compounds not a guess.

Fast bioavailability

A liquid glycerin extract absorbs quickly, so you feel support in as little as one hour, not weeks.

FAQs

Frequently Asked Questions

We're always happy to answer your questions

Lion’s Mane is a large white mushroom that naturally grows on hardwood trees and has been used in traditional medicine for centuries. Known for its striking appearance that resembles the mane of a lion, this ‘super-mushroom’ is rich in bioactive compounds like hericenones and erinacines, which are molecules shown to support nerve growth and brain health. 

Unlike many common culinary mushrooms, Lion’s Mane has gained significant scientific interest for its potential to support mental performance, mood balance, and healthy neurological systems. Lion’s Mane is understood to support cognition by promoting the production of Nerve Growth Factor (NGF), a vital protein involved in the maintenance, repair, and regeneration of neurons.

Logic Lion’s Mane is standardized to contain bioactive compounds known for cognitive and neurological benefits, called beta-glucans (1,3 / 1,6).  Standardization means each serving delivers a consistent, clinically relevant amount of these compounds, unlike generic Lion’s Mane products which can vary widely in potency and effectiveness.†︎

There are a few main differences between Logic Lion’s Mane Nootropic and other nootropic / Lion’s mane formulas. 

Firstly: Logic contains the only clinically proven Lion’s Mane Nootropic to enhance focus, improve working memory, lead to better reaction times, and improve emotional wellbeing over placebo by 3-600% in double-blind, randomized, placebo-controlled clinical studies.†︎

It also was found to work fast. In the same gold-standard clinical trial, Lion’s Mane in Logic was shown to quickly start boosting cognition – with measurable improvements in mental processing speed in as little as one hour after the first dose. This means data from the MycoThrive™ Lion’s Mane in Logic isn’t just based on tradition or anecdote, but on rigorous scientific evidence that found fast-acting benefits for cognition.

There’s also another big difference. Unlike questionable mushroom supplements that may use cheap grain fillers or mycelium grown on rice or oats, Logic contains premium Lion’s Mane fruiting bodies with no fillers, starch, or hidden carriers. That matters because grain-based products can dilute potency, leaving you with little more than ground-up grain instead of the bioactive compounds responsible for cognitive benefits. It’s also important to know that what you are putting into your body is safe and free of harmful contaminant levels, which has become a chief concern in the supplement industry as of late. Logic Lion’s Mane is third party lab tested by FDA-registered and ISO accredited labs for purity and potency across contaminants like lead, arsenic, mercury, yeast, mold, and much more.†︎

In a double-blind, randomized, placebo-controlled crossover trial published in Nutrients, researchers evaluated the short-term cognitive and mood effects of a single 1,000 mg dose of MycoThrive™ Lion’s Mane mushroom extract found in Logic, in healthy adults. 

The study was designed to assess attention, working memory, mental processing speed, and overall mood. Participants received one of three treatments in separate sessions: 1,000 mg of MycoThrive™ Lion’s Mane, 650 mg of guayusa extract, or a placebo. Cognitive testing was conducted at three points: before dosing, and again 60 and 120 minutes after ingestion, to capture the acute effects of each formula.

Results showed that those who took MycoThrive™ Lion’s Mane found in Logic experienced significant gains in working memory, concentration, and reaction time compared to placebo, along with meaningful improvements in mood and subjective well-being. Participants reported feeling more focused, calm, and positive, indicating that MycoThrive™ Lion’s Mane found in Logic supports both cognitive clarity and emotional balance in as little as two hours after a single serving.

Results of the clinical study found a 6x increase in mental processing speed compared to placebo, 400% improvement in reaction speed compared to placebo, a 10% enhancement in cognitive performance, and approximately 4x improvement in in mood and feelings of happiness compared to placebo – all in just 120 minutes. Logic Lion's Mane features the clinically studied MycoThrive™ extract, delivered through a proprietary liquid extraction process, providing a total of 970 mg per daily serving (485 mg twice daily).†︎
