N-Acetylcholine-Cysteine is capable of crossing the blood-brain barrier and is known to combat oxidative stress, and reduced oxidative stress may support healthier nerve tissue. [1]

L-carnitine is a vital cofactor for mitochondrial oxidation of fatty acids providing the brain with an energy substrate. Acetylcholine-L-carnitine, an ester of L-carnitine, possesses properties that may be effective in supporting healthy cognition with age.* [2,3]

Gingko Biloba leaf extract contains two main bioactive constituents – ginkgoflavonglycosides (24%) and terpene lactones (6%) – and is used in the formula because of its reported stress-alleviating and memory-supportive effects as well as its ability to support the health and integrity of neurons. The mechanisms of action may be mediated through its antioxidant, antihypoxic, and micro circulatory actions.*[7]

The Ayurvedic herb Bacopa Monnieri has reported cognition-facilitating, cytokine-modulating, and anti-stress effects. These effects are thought to be mediated through its remarkable free-radical scavenging capacity and its protective effect of DNA cleavage.*[6]

Vinpocetine is derived from vincamine, an alkaloid extracted from the periwinkle plant (Vinca minor). It has been used extensively in Eastern Europe, and more recently in the United States, to support cerebrovascular health and healthy mental function. Vinpocetine’s roles in supporting brain function are multi-modal and include its influence on cerebral circulation, its antioxidant activity in the brain, and its rol in affecting ion channels and cytokine production.* [7-9] Together, these varied actions support overall brain tissue health and function. The efficacy and safety of vinpocetine have been tested and validated by in vitro, animal, and human studies. Many human studies demonstrate positive results in neurological functioning – primarily related to capillary blood flow and cellular metabolism.*[10-13]

Huperzine A (HupA), like vinpocetine, affects ion channels. Such activity has been found to support healthy learning and memory. HupA may have a positive effect on levels of acetylcholine through its action on acetylcholinesterase (AChE). Acetylcholine is one of the chemicals that our nerves use to communicate in the brain, muscles, and other areas. HupA has been found to support healthy cognition in a broad range of animal models, and phase IV clinical trials in China demonstrated that HupA was valuable in promoting healthy recall and cognition in elderly subjects.*[14]

Choline, an essential nutrient, plays a critical role in cognition, and may help prevent dementia and mild cognitive impairment. Research suggest that moderate dietary choline intake, ranging from 332.89 mg/d to 353.93 mg/d, is associated with lower odds of dementia and better cognitive performance.*[15]
