Information of the key ingredients of BrainPower Advanced.

Ingredients Main active compounds Effects and possible mechanisms of actions
Phosphatidylserine Phosphatidylserine Improves cognitive performance in elderly adults with memory deficits
Enhances cognitive performance in school children and adults
Restores impaired neuronal calcium and glucose uptake and metabolism in aged brain
Precursor of neuronal membrane phospholipid that is responsible for neuroplasticity, learning, and memory
Neuroprotection

Catharanthus roseus Vinpocetine Enhance memory function in young healthy volunteers and in animals
Protect against ischemia by improving blood perfusion and cerebral blood flow
Increase glucose and oxygen consumption, cerebral ATP, and cAMP levels
Improve cerebral microcirculation by inhibiting platelet aggregation
Reduce red blood cell deformability and cerebral vascular resistance
Enhance neurotransmitter production, release, and concentration in the brain
Block voltage-gated sodium channels and potentiate the neuroprotective effect of adenosine in hypoxia

Huperzia serrata (whole plant) Huperzine A
Huperzine B
Inhibitor of AChE and NMDAR
Inhibitor of b-amyloid neurotoxicity
Strong antioxidative, antiapoptotic, and neuroprotective activities
Improve cognition in healthy people
Reverse or attenuate cognitive deficits in older adults

Ginkgo biloba Flavonoids
Terpenoids
Terpene lactones (ginkgolides and bilobalide)
Large dose may improve cognition, daily living activities, and mood
Dose-dependent and specific enhancing effects on memory, cognitive performance, and alertness in healthy adults
Delay cognitive decline in elderly population
Potentiate the cognitive-enhancing effects of phosphatidylserine
Memory improving effect in older people with memory deficits
Increase blood supply, vasodilation, reduce blood viscosity, balance neurotransmitter systems, and reduce free radicals
Inhibitor of platelet activating factor

Vitamin B6 Pyridoxal, pyridoxamine, and pyridoxine Homocysteine remethylation cofactor
Reduce blood homocysteine level which is a risk factor for cerebrovascular disease and neuron toxicity

Vitamin B12 Required for the methylation of homocysteine to methionine and needed for myelin, neurotransmitters, and membrane phospholipids for maintaining the integrity of the central nervous system
Protects against brain atrophy
Protects mood and memory function

L-Tyrosine L-Tyrosine Promotes protein utilization and enhances IgG antibody induction

L-Pyroglutamic acid L-Pyroglutamic acid Makes N-terminal modification in neuronal peptides, hormones and peptides, and analogue/reservoir of glutamate

Green tea extract
(Camellia sinensis, leaf)
Tea polyphenols (epigallocatechin gallate) Free-radical scavengers, strong antioxidants, and neuroprotection
Anti-inflammatory; improve vasodilation and normal blood pressure, normal glucose, and lipid metabolism

Acetyl-L-carnitine Acetyl-L-carnitine Regulates neuroplasticity, membrane function, and neurotransmitter release; reduces pain and depression activity at cholinergic neurons; membrane stabilization; and enhancing mitochondrial function

Cola nut extract (kola nitida) Caffeine
Theobromine
Theophylline
Decrease brain beta-amyloid

Choline bitartrate A precursor of acetylcholine, a cholinergic neurotransmitter that declines with advancing age
Improves auditory and visual word recognition at a dose of 12 g per day for 2 weeks

L-Glutamine Reduces beta-amyloid and H2O2-induced stress and DNA damage

L-Phenylalanine An essential amino acid that can be converted to tyrosine and other excitatory neurotransmitters (dopamine, norepinephrine, and epinephrine)

L-Cysteine A precursor of the antioxidant glutathione and a flavor
