Scientifically Reviewed By Dr. Ryan Hakim MD

After reviewing Logic Lion’s Mane and its referenced randomized, double-blind, placebo-controlled crossover trial (La Monica et al., Nutrients 2023), I found that the product’s core claims—acute support for attention, working memory, and reaction time in healthy adults—are consistent with the study’s findings following a ~1 g dose of standardized Lion’s Mane extract assessed 60–120 minutes after ingestion.

Frequently Asked Questions

We're always happy to answer your questions

Lion's Mane is a large white mushroom that grows on hardwood trees and has been used in traditional medicine for centuries. It's rich in bioactive compounds like hericenones and erinacines, shown to support nerve growth and brain health by promoting Nerve Growth Factor (NGF), a protein involved in the maintenance and repair of neurons. Logic is standardized to beta-glucans (1,3 / 1,6) so every serving delivers a consistent, clinically relevant amount.¹

Logic is the only Lion's Mane nootropic clinically proven to enhance focus, working memory, reaction time, and emotional wellbeing versus placebo in double-blind, randomized studies - with measurable improvements in as little as one hour after the first dose.† It's also made from premium Lion's Mane fruiting bodies, not cheap mycelium grown on grain, so there are no fillers, starch, or hidden carriers diluting potency. And every batch is third-party tested by FDA-registered, ISO-accredited labs for purity and potency across contaminants like lead, arsenic, mercury, yeast, and mold.¹

In a double-blind, randomized, placebo-controlled crossover trial published in Nutrients, a single 1,000 mg dose of the MycoThrive™ Lion's Mane extract found in Logic was tested against placebo in healthy adults. Within two hours, participants showed significant gains in working memory, concentration, reaction time, and mood. Logic delivers this clinically studied extract through a proprietary liquid extraction process at 970 mg per daily serving (485 mg twice daily).¹

Kosher: Logic is made in a Kosher Certified facility (OU-approved for Passover) and uses only USP-Grade Kosher Certified vegetable glycerin. Note: the facility is certified, but Logic itself is not a Kosher Certified product.

Halal: Logic is made in a Halal Certified facility (ISA Islamic Services of America) and uses only USP-Grade Halal Certified vegetable glycerin. Note: the facility is certified, but Logic itself is not a Halal Certified product.

I’ve been using this product for several months now and have been thrilled with the results. It has truly given me the needed mental focus and clarity to face the day’s challenges. I usually add it to my smoothies but it tastes great on its own as well. Highly recommend!!
