MemoryFuel: Brain Support Supplement That Works

This is where things get interesting. Let’s go through each ingredient and what the research says.

Creatine Monohydrate
Creatine is the headline ingredient, and it deserves the attention. While most people know it as a gym supplement, its role in brain energy metabolism is well-documented. According to research supported by Weill Cornell Medicine and covered in neuroscience circles, creatine helps maintain ATP levels in the brain, directly speeding up memory access and cognitive processing.
It essentially closes the “ATP gap” that MemoryFuel is designed to target.

L-Theanine
L-theanine is an amino acid found naturally in green tea leaves. It’s widely studied for its ability to promote calm, alert focus — without drowsiness or the crash associated with stimulants. Research published in Nutritional Neuroscience (2008, Rethinking & Fox) showed that L-theanine increases alpha brain wave activity, which is linked to a relaxed but mentally engaged state.
In MemoryFuel, it acts as a mental “steadying” agent — preventing stress from burning through your cognitive resources.

Choline Bitartrate
Choline is a precursor to acetylcholine, one of the most important neurotransmitters for learning and memory. Without enough choline, your brain’s memory networks communicate more slowly and less efficiently. According to the National Institutes of Health, choline is an essential nutrient that many adults don’t get enough of from diet alone.
By boosting acetylcholine production, choline bitartrate helps your brain’s internal communication system work faster and more clearly.

Magnesium Glycinate
Magnesium plays a critical role in regulating the stress response. When cortisol levels spike — whether from daily stress or poor sleep — they can literally damage brain cells and disrupt cognition. Magnesium glycinate is considered one of the most bioavailable forms of magnesium, meaning your body absorbs it well.
Research published in Neuron journal has shown that magnesium supplementation can increase synaptic plasticity, which is your brain’s ability to form and strengthen connections — the foundation of memory.

Vitamin D3
Vitamin D3 isn’t just for bone health. It has a well-documented role in brain health too. According to research from the Vitamin D Council and studies published in The Journal of Alzheimer’s Disease, low vitamin D levels are associated with cognitive decline and increased neuroinflammation.
In MemoryFuel, D3 helps lower brain inflammation and strengthens the immune system’s ability to protect neural tissue.

Vitamin B12
B12 is essential for maintaining the myelin sheath — the protective coating around your nerve fibers. When myelin degrades, nerve signals slow down, and cognitive function suffers. B12 also supports ATP production in brain cells, working in synergy with creatine to keep your mental energy levels stable.
A deficiency in B12, which is increasingly common especially in adults over 50, is directly linked to brain fog and poor memory according to Harvard Medical School resources.
