Our ingredients are shown to improve memory
†: According to research conducted by Wilkinson et al. at the University of Northumbria, using chewing gum as an associative stimulus improved delayed word recall by up to 35% compared to a control group.**
††: Clinical testing published by researchers at the University of Northumbria demonstrated that utilizing chewing gum as an associative memory trigger increased long-term memory recall by up to 36% compared to non-chewing control groups.**

†††: In a double-blind, randomized controlled trial, the group treated with Huperzine A demonstrated a 74% improvement rate in cognitive function compared to a 40% improvement rate in the placebo control group ($p < 0.05$). This represents a 34-percentage-point absolute increase and an 85% relative increase in the probability of clinical improvement (Zhong et al., 1996).

Ingredients That Work
Purposeful ingredients. Proven benefits.
Every ingredient is thoughtfully selected, combining function, quality, and science to deliver benefits you can trust.
Energy
B Vitamins
B vitamins are the foundation of cognitive function. They convert nutrients into usable brain energy and build the neural pathways that support learning and memory.
B1 (Thiamine), the spark plug
Converts glucose into ATP, the raw fuel your brain needs to process information and prevent mental fatigue.
B6 (Pyridoxine), the engine
Synthesizes dopamine and serotonin, transforming L-Tyrosine into active motivation and mood stability.
B9 (Folate), the driver
Repairs DNA and RNA while building neural pathways, directly supporting memory formation and brain plasticity.
Motivation
L-Tyrosine
L-Tyrosine, the motivation molecule, is a precursor to dopamine, the neurotransmitter that drives focus and motivation. Research shows it enhances cognitive performance under stress and supports sustained attention during demanding tasks.
Memory
Huperzine A
Huperzine A, the memory molecule, supports acetylcholine levels for memory formation.
Sharpens Memory Recall
Huperzine works by preserving acetylcholine, the neurotransmitter essential for memory encoding and retrieval. Clinical studies demonstrate its ability to enhance both short-term recall and long-term retention.
Focus
L-Theanine
L-Theanine, the smooth operator, can amplify focus while eliminating jitters. Theanine has been shown to increase alpha brain waves, promoting calm alertness without the crash.
- Reduces caffeine-induced anxiety
- Enhances attention span and clarity
- Promotes relaxed mental state
How It Works
Chewing breaks down the gum base and activates the ingredient blend for the mucous membrane to absorb them directly into the bloodstream. Bypassing the digestive system for a faster onset of action.
Step 1
Sublingual Absorption
Begins in the mouth, where compounds absorb through oral tissues, bypassing slow digestion.
Step 2
Brain
Activation
Within minutes, key ingredients reach the brain to support focus, clarity, and cognitive performance.
Step 3
Sustained Cognitive Edge
For hours, B vitamins support energy while nootropics help maintain focus and mental performance.
Questions
Find answers about how LRN Gum works and what to expect.
Is LRN Gum safe?
LRN Gum contains clinically studied ingredients at effective doses. All components are recognized as safe by regulatory bodies and have been used in research for cognitive enhancement. If you have specific health concerns or take medications, consult your doctor before use.
How long until I feel it?
Most users report noticeable effects within 15 minutes of chewing. The combination of L-Theanine and caffeine kicks in first, followed by sustained focus from L-Tyrosine and the B vitamin complex. Individual response times vary based on metabolism and baseline caffeine sensitivity.
Can I use it daily?
Yes, LRN Gum is designed for daily use. The ingredients support cognitive function without building tolerance or causing dependency. One piece per day is the standard recommendation, though you can adjust based on your needs and schedule.
What makes this different?
LRN Gum combines three proven nootropics with a complete B vitamin stack, all in a format you can use anywhere. We skip the marketing hype and focus on molecules with real research backing their cognitive benefits. No filler, no proprietary blends, just science.
Does it contain caffeine?
Each piece contains a moderate amount of caffeine paired with L-Theanine to smooth out jitters and extend focus. This combination delivers sustained alertness without the crash you'd get from caffeine alone. If you're sensitive to caffeine, start with half a piece.
