Herbs and Nutrients to Keep Your Memory Sharp

If you’ve ever walked into a room and couldn’t remember why you were there; misplaced your keys (or even your car in a parking lot); or forgotten the name of an acquaintance, you might have momentarily wondered about your memory or if you were losing your mind. If you’re over the age of 50, you might even be seriously concerned about the possibility of Alzheimer’s.

It’s a valid concern. According to the 2008 Alzheimer’s Association figures, more than five million Americans over the age of 65 have Alzheimer’s disease. In addition, approximately 500,000 Americans under the age of 65 suffer from Alzheimer’s or other forms of dementia.

Although a decline in memory and brain function is generally regarded as an inevitable part of growing older, in reality, brain aging is caused by poor cerebral circulation, mitochondrial dysfunction, inflammation, oxidative damage, and decreased levels of anabolic-repair hormones, including DHEA and testosterone. All of these factors contribute to changes in the brain that lead to neuronal degeneration and cognitive impairment.

Gingko for memory

Many people are surprised to learn that stress affects brain health. But chronically elevated stress hormones are a principal trigger of all of the physiological factors implicated in brain and memory dysfunction. Here’s how stress influences the brain: The main stress hormones (epinephrine and glucocorticosteroids) ensure that the body has a “memory” of events and situations that may be dangerous in the future. While this adaptive response is obviously beneficial for survival, when there is repeated or chronic stress at higher than normal levels sustained over days, months, or even years, brain function suffers. Chronic stress forces the glucocorticosteroid set point to remain high due to adrenal overactivity. This results in atrophy of the neurons in the hippocampus and the inhibition of ongoing neurogenesis. In other words, the brain loses its ability to function at high levels and brain cell regeneration diminishes.

Following sustained periods of stress, allostatic overload may occur and neurons can actually die. Through some or all of these processes, the hippocampus shrinks, and normal function and response are impaired. This is how prolonged stress contributes to dementia and loss of optimal brain health.

I strongly believe that aging does not have to be accompanied by mental decline or neurological problems. As with other diseases associated with aging, I’ve found that adaptogens should be regarded as the primary foundational support for reducing stress-induced brain damage. Because the brain is a major target for glucocorticoids and stress hormone toxicity, treatment strategies aimed at regulating abnormal levels of glucocorticoids are imperative.

Neurological Health

Studies clearly show that adaptogenic formulas that include herbs such as ginseng (Panax spp.), eleuthero (Eleutherococcus senticosus), ashwagandha (Withania somnifera), and rhodiola (Rhodiola rosea) effectively mediate the oxidative stress inherent in degenerative and neurological diseases. Primary adaptogens such as these stimulate anabolic metabolism and raise levels of anabolic hormones, including testosterone. This is important, because low levels of anabolic hormones escalate the risk for dementia and Alzheimer’s disease.

In addition, in my extensive research and clinical practice I’ve identified several botanicals and nutritional compounds that specifically target brain function:

  • Bacopa (Bacopa monniera) is rich in steroidal saponins called Bacoside A and B that influence the central nervous system by stimulating the gaba-aminobutyric acid (GABA) and cholinergic systems. This has a calming effect on the brain and increases the ability to retain information.
  • Gotu kola (Centella asiatica) is an Ayurvedic brain tonic used to enhance memory and strengthen the central nervous system. Research suggests that chemical compounds called triterpenes are the active constituents responsible for its therapeutic effects.
  • Ginkgo (Ginkgo biloba) protects and enhances memory and focus by promoting healthy blood flow and oxygenation to the brain; it also neutralizes free radicals through its antioxidant activity.
  • Acetyl L-Carnitine facilitates the transport of fatty acids into the energy-producing units within cells, and is essential for cellular respiration and mitochondrial health. It provides a neuro-protective effect by promoting efficient energy production and providing antioxidant activity.
  • Phosphatidylserine is a phospholipid that promotes membrane fluidity and encourages healthy glucose metabolism by the brain. Research suggests that it has the ability to enhance memory and learning as well as general mental acuity.
  • Vinpocetine is a semisynthetic derivative alkaloid from the periwinkle plant (Vinca minor). It enhances cerebral blood flow and encourages a normal inflammatory response within the brain.
  • Huperzine A is a sesquiterpene alkaloid extracted from a club moss (Huperzia serrata). Researchers are focusing on the ability of Huperzine A to enhance memory and support healthy neurological function.

In my clinical experience, I’ve found that an overall healthful lifestyle, combined with adaptogenic support and specific nutrients for enhancing brain function, is the key to keeping your memory sharp and your brain functioning optimally, no matter what your age.

  1. I read in the above very well written article that the herbs you mentioned such as Bacopa help memory etc but can also raise testosterone levels. Should a female who has already high testosterone levels, then not use these particular herbs ? What herbs then would be good for memory etc. Thanks.

    1. Bacopa does not specifically increase testosterone levels. The adaptogens that do target the HPA axis will only raise testosterone levels if deficient. My favorite herbs for improved memory functions are bacopa and gotu kola.

    1. Yes – Gotu Kola & Ginkgo Biloba are certainly safe to use together. I have created a cognitive function formula with both to enhance focus and memory. Ginkgo is a bit more specific for peripheral circulation and Gotu kola for calming the nervous system – so I use them both.
