Creatine Monohydrate (5g)

Creatine is renowned for powering athletic performance, but it also plays a key role in brain energy metabolism. By replenishing ATP—the energy currency of cells—it helps your neurons fire efficiently, supporting memory, focus, and mental stamina.

A landmark double-blind, placebo-controlled trial gave vegetarians 5 g/day of creatine for six weeks and saw significant improvements in both working memory (backwards digit span) and general intelligence (Raven’s Advanced Progressive Matrices).*

Alpha GPC (300mg)

Alpha-GPC is a choline donor that helps fuel the neurotransmitter acetylcholine—key for memory, learning, and mental sharpness.

In human clinical studies, Alpha-GPC significantly improved memory and attention in individuals with cognitive decline, suggesting benefits for mental performance and brain function.

L‑theanine (200mg)

is a naturally occurring amino acid, known for promoting a calm yet alert mental state. Unlike sedatives, it doesn’t dull your thinking—it enhances it. L‑theanine increases alpha brain waves, which are associated with relaxed focus and creative thinking, while modulating key neurotransmitters like GABA, dopamine, and serotonin.

Its real power shows when combined with caffeine. Together, they deliver sharper attention, smoother energy, and reduced mental fatigue—without the jittery edge.

A double-blind, placebo-controlled study gave participants 100 mg of L‑theanine and 50 mg of caffeine and found significant improvements in task-switching accuracy, reaction time, and reduced distraction, compared to either compound alone.

L-Tyrosine (500mg)

L-Tyrosine is an amino acid that supports dopamine production, helping you stay sharp when it counts—especially under stress or fatigue.

Research shows that L-Tyrosine can improve working memory and task performance during demanding mental tasks and sleep deprivation.*

Acetyl L-Carnitine (1.5g)

Acetyl L-Carnitine (ALCAR) supports mitochondrial function and cellular energy production in the brain—key for mental clarity, especially as we age.

A 28-day randomized controlled trial in healthy adults found that supplementation with ALCAR significantly improved attention, focus, and working memory.

Electrolytes (658mg)

When you sweat, train, or even just focus hard for long periods, your body loses key minerals like sodium, potassium, and magnesium. These electrolytes regulate hydration, nerve signaling, and muscle function. Without enough of them, fatigue sets in faster, concentration dips, and recovery drags. By replenishing electrolytes, PurpleMind helps you stay sharp and steady.

Butterfly Peaflower (300mg)

This vibrant blue flower is rich in anthocyanins that help combat oxidative stress and inflammation—two factors tied to mental and physical fatigue.

Early studies suggest that Butterfly Pea Flower extract may have neuroprotective and antioxidant effects.
