A fat-soluble vitamin essential for calcium absorption and bone health, increasingly recognised for its neuroprotective properties and role in cognitive function. Often called the "sunshine vitamin," it acts more like a hormone in the body, with receptors found throughout the brain.
Guarana
Guarana (Paullinia cupana) is a South American berry containing one of the highest natural concentrations of caffeine. It provides sustained mental energy, improved alertness, and enhanced physical endurance with a smoother, longer-lasting effect than coffee.
Valerian
Valerian (Valeriana officinalis) is one of the most well-established herbal sedatives, used since ancient Greek and Roman times for insomnia and nervous restlessness. It increases GABA availability in the brain to promote deep, restorative sleep and reduce anxiety.
Theobromine
Theobromine is a mild stimulant found abundantly in cocoa and dark chocolate. Structurally similar to caffeine but with a gentler, longer-lasting effect, it enhances blood flow to the brain, promotes alertness without jitteriness, and may support mood through endorphin and serotonin pathways.
Vitamin B1 (Thiamine)
Vitamin B1 (thiamine) is an essential B vitamin that plays a critical role in brain energy metabolism by converting glucose into ATP. Low thiamine levels are closely linked to cognitive impairment, poor concentration, and neurological damage, making adequate intake vital for healthy brain function.
Clitoria Ternatea (Butterfly Pea)
Clitoria ternatea, commonly known as butterfly pea flower, is a traditional Ayurvedic herb used as a brain tonic for centuries in Southeast Asia. Animal research suggests it may enhance memory and learning through acetylcholinesterase inhibition and antioxidant neuroprotection, though human clinical data remains limited.
Agmatine Sulfate
A naturally occurring neuromodulator derived from the amino acid arginine that modulates NMDA receptors, nitric oxide, and multiple neurotransmitter systems for mood enhancement, pain relief, and neuroprotection.
Spermidine
A naturally occurring polyamine that induces autophagy - the body's cellular cleanup process - associated with improved memory, neuroprotection, and longevity in both animal and human observational studies.
Glutathione
The body's most abundant endogenous antioxidant and master detoxifier - protects neurons from oxidative damage, supports mitochondrial function, and is depleted by ageing, stress, and environmental toxins.
Alpha-GPC
Alpha-GPC is a highly bioavailable choline compound that crosses the blood-brain barrier, supporting acetylcholine synthesis for cognitive function, memory, and physical performance. Clinical evidence supports benefits in age-related cognitive decline.
Ginkgo Biloba
Ginkgo Biloba is an ancient herbal extract derived from the leaves of the oldest living tree species. Widely used to support cerebral blood flow, memory, and cognitive function - particularly in older adults experiencing age-related cognitive decline.
Lecithin
Lecithin is a phospholipid complex found abundantly in egg yolks and soybeans. It is a rich source of choline and phosphatidylcholine, both essential for acetylcholine synthesis, brain cell membrane integrity, and healthy cognitive function throughout life.
Sulforaphane
A broccoli-derived compound that activates the Nrf2 antioxidant pathway - the body's master regulator of cellular defence - reducing neuroinflammation, supporting detoxification, and protecting against neurodegenerative disease.
NAC (N-Acetyl Cysteine)
N-Acetyl Cysteine (NAC) is a supplement form of the amino acid cysteine that serves as a powerful antioxidant and precursor to glutathione, the body's master antioxidant. It supports liver health, respiratory function, and mental health through neuroprotective and neurotransmitter-regulating mechanisms.
Fenugreek
A traditional herb increasingly used to support healthy testosterone levels, sexual function, and blood sugar control. Fenugreek seeds contain unique compounds that may enhance libido, improve insulin sensitivity, and provide cognitive benefits through dopaminergic mechanisms.
Chaga Mushroom (Inonotus obliquus)
A parasitic fungus with one of the highest antioxidant capacities of any natural substance, traditionally used in Siberian and Nordic folk medicine for immune support and increasingly recognised for neuroprotective potential.
L-Glutamine
L-Glutamine is the most abundant amino acid in the body and a precursor to both glutamate (the primary excitatory neurotransmitter) and GABA (the primary inhibitory neurotransmitter). It supports cognitive function, gut-brain axis health, and mental clarity during periods of stress or intense physical activity.
Vitamin B5 (Pantothenic Acid)
Vitamin B5 (pantothenic acid) is an essential vitamin required for the synthesis of coenzyme A (CoA), a molecule involved in over 100 metabolic pathways including brain energy production, acetylcholine synthesis, and the production of steroid hormones that influence cognitive function.
Taurine
Taurine is a sulphur-containing amino acid that acts as a neuromodulator in the brain, supporting cognitive function, neuroprotection, and cardiovascular health. It has gained attention for its calming effects and potential role in healthy ageing.
Turkey Tail Mushroom (Trametes versicolor)
One of the most researched medicinal mushrooms, turkey tail contains polysaccharide-K (PSK) and polysaccharopeptide (PSP) - potent immunomodulators that influence neuroinflammation and support cognitive health through the immune-brain axis.
Piperine (BioPerine)
The primary bioactive alkaloid in black pepper - dramatically enhances the bioavailability of other nootropics and supplements while also providing its own serotonergic, anti-inflammatory, and neuroprotective effects.
Apoaequorin
Apoaequorin is a calcium-binding protein originally derived from the bioluminescent jellyfish Aequorea victoria. Marketed primarily under the brand name Prevagen, it is promoted for memory support, though its evidence base is limited and largely brand-sponsored.
