Cogni-flex™, provided by Douglas Laboratories, is
a unique combination of nutrients and herbs (huperzine A, Ginkgo biloba,
phosphatidyl serine, and acetyl-L carnitine) which work in concert to maintain
and enhance brain and nervous system functions, including those involved in
mental alertness, clarity, and memory retention. These positive effects of
the four components of Cogni-flex™ upon structure and function of the nervous
system are supported by numerous scientific/clinical studies The four nutrients in Cogni-flex™ support the
structure and function of cognitive processes in several ways. They support
neurotransmitter metabolism, enhance vascular circulation to the brain, and help
maintain structure and function of nerve cell membranes. Huperzine A: An extract
of the Chinese club moss, Huperzia serrata, huperzine A has been used in Chinese
medicine for centuries. It is an effective inhibitor of acetylcholinesterase,
the enzyme that degrades acetylcholine, the neurotransmitter important for
normal memory and learning function. Huperzine A may help maintain cognitive
function that has been degraded by a reduction in the brain’s functional levels
of the neurotransmitter acetylcholine. Ginkgo biloba: Flavonoid compounds and
terpene lactones in the ginkgo leaf help regulate the structural tone and
elasticity of arteries and capillaries. As powerful antioxidants, the ginkgo
flavonoids counteract the deleterious actions of free radical accumulation which
impairs functional cellular energy production and nerve transmission. Ginkgo
biloba extract is also reported to inhibit the tendency of red blood cells to
stick together (“clumping”), thereby enhancing the functional fluidity of the
blood. Improving the functional circulation to the brain and other parts of the
body allows for better oxygen and glucose uptake, with subsequent enhancement of
memory and mental functions. Phosphatidylserine: This phospholipid, found in
high concentrations in the nervous system, helps maintain functional fluidity of
nerve cell membranes, thus providing for optimal transport of nutrients and
other compounds across the cell membrane. It is also used in the repair and
regeneration of nerve cells. Phosphatidylserine also appears to help the body
counterbalance excessive release of adrenocorticotropic hormone (ACTH),
adrenaline, and cortisol which are released in response to stress. Acetyl-L-carnitine:
This acetylated high energy ester of the amino acid L-carnitine contributes its
acetyl group to the production of acetylcholine, the primary neurotransmitter
for memory and thought. The enzyme that makes acetylcholine from acetyl groups
and choline is choline acetyl transferase. The activity of this important enzyme
has a tendency to decline with age, causing low acetylcholine levels which in
turn are thought to contribute to the impairment of brain function that is
associated with aging. Research has also found that acetyl-L-carnitine is active
in optimizing the functioning of cerebral blood flow, as well as of nerve cell
membranes. Cogni-flex™ capsules may be a useful dietary
supplement for those who wish to support the healthy functioning of their mental
processes. Adults take 1 capsule daily or as directed by
physician. No adverse side effects reported Store in a cool, dry place, away from direct
light. Keep out of reach of children. Brooks JO, 3rd, Yesavage JA, Carta A, Bravi D. Acetyl L-carnitine
