Red ginseng's ability to 'help improve memory' is a functionality officially recognized by the Ministry of Food and Drug Safety in 2010. Ginsenosides help secrete neurotransmitters involved in memory and learning, and coordinate stress responses to make the brain less vulnerable to fatigue. The daily intake standard for ginsenosides for which this functionality is recognized is 2.4mg to 80mg.

• "I've been forgetting things a lot lately, will red ginseng help my memory?"

• "Are improving memory and preventing dementia different?"

• "I'm worried about my parents' memory, so I'm considering red ginseng as a gift."

What exactly is memory?

According to the functional ingredient guide by the Ministry of Food and Drug Safety (Food Safety Korea), memory is the ability to take in necessary information, store it in the brain, and retrieve and use it when needed.

When you feel like "I've been forgetting things a lot lately," this is mainly a phenomenon where the process of storing and recalling information is not as smooth as before. As you age, or as chronic stress and fatigue build up, this process is affected.

Two main causes of declining memory

There are various causes of memory decline, but there are two main pathways linked to the functionality of red ginseng.

A decrease in neurotransmitters responsible for memory in the brain Specific neurotransmitters play a key role in learning and memory. As we age, the ability to secrete these substances tends to gradually decrease.

Accumulation of stress creating a burden on the brain Under chronic stress, stress hormones are secreted excessively. If this continues for a long time, it puts a burden on the brain areas that store memory, and can affect both memory and concentration.

Why red ginseng is attracting attention for memory

The memory functionality of red ginseng was officially recognized by the Ministry of Food and Drug Safety in 2010.

The expression approved by the Ministry of Food and Drug Safety is as follows.

May help improve memory

If the ginsenoside content is 3mg or more, it meets all 5 functional criteria.

How red ginseng works on memory

Promoting the secretion of neurotransmitters that support memory and learning

Ginsenosides are known to act in a way that promotes the secretion of neurotransmitters in the brain areas responsible for memory and learning. When these neurotransmitters are sufficiently secreted, information is stored efficiently and recalled well when needed.

Protecting the brain by regulating stress responses

The 'Adaptogen' action explained in the fatigue improvement section is connected here as well. Since red ginseng regulates the body so that it does not react excessively to stress, the burden of stress hormones on the brain naturally decreases.

Improving blood flow to the brain

According to a study by the Rural Development Administration, it has been reported that ginsenosides can help memory by helping the absorption of glucose, which is used as energy in the brain, and facilitating blood flow in the brain. The blood flow functionality discussed in Chapter ② (Blood Circulation Improvement) and the memory functionality connect at this point.

Improving memory is different from preventing dementia

It is important to make this distinction clear.

The memory functionality of red ginseng recognized by the Ministry of Food and Drug Safety means helping to maintain normal memory function. It does not mean preventing or treating dementia.

Related research is ongoing. The Dementia Science Research Institute at Konyang University and the Natural Products Efficacy Research Institute of KGC Ginseng Corporation researched the mechanism by which red ginseng components inhibit the aggregation of Alzheimer's disease-causing substances and published it in an international academic journal in 2021. However, this is a study targeting animal models, and is distinct from the scope of functionality recognized by the Ministry of Food and Drug Safety.

If cognitive decline is severe enough to cause worry, consulting a medical specialist should come before health functional foods.

What to check when choosing a product

If it is a red ginseng product, make sure to check the 3 things below.

Check if there is a health functional food label. Only when there is a health functional food mark can the functionality recognized by the Ministry of Food and Drug Safety be displayed.

Check if the functional phrase is accurate. It is important to see if there is a designated expression such as "May help improve memory."

Check if the ginsenoside content is sufficient. The daily standard for memory improvement functionality is 2.4mg or more. Look at the functional ingredient indication on the back of the product.

One thing you must keep in mind

If memory decline is severe or lasts for a long time, it may not be a simple drop in condition. There may be other causes such as sleep disorders, thyroid dysfunction, or anemia.

Health functional foods are not products intended to treat diseases. It is recommended to use red ginseng as one method for daily memory management, and to consult a specialist if abnormal symptoms persist.

Frequently Asked Questions

Q. How long does it take for the memory improvement effect to appear? 

A. Health functional foods are not expected to produce immediate effects like medical drugs. It is a way to gradually help manage memory through steady intake, and regular intake over a certain period is generally recommended.

Q. Do memory improvement and dementia prevention mean the same thing? 

A. No, they are different. The Ministry of Food and Drug Safety's recognized functionality for red ginseng is to help maintain normal memory function. Preventing or treating dementia is a separate medical area, so if you are worried about such symptoms, consulting a specialist is priority.

Q. My parents' memory has dropped a lot, can I give them red ginseng? 

A. If it is for daily health care, you can choose a product after checking the health functional food mark and ginsenoside content. However, if cognitive decline is severe or if they are taking other medication, it is recommended to consult a doctor or pharmacist first.

Q. Are there red ginseng products that fulfill both memory and fatigue functionalities at the same time? 

A. Yes, there are. If the ginsenoside content is 3mg or more, it meets both the standards for memory improvement (2.4mg or more) and fatigue improvement (3mg or more). Check the product label to see if both functionalities are displayed together.

Conclusion

The memory functionality of red ginseng does not mean "your memory will improve immediately upon eating."

It helps with daily memory management as ginsenosides steadily act in a way that helps secrete memory-related neurotransmitters, regulates stress responses, and facilitates blood flow in the brain.

Looking back as we wrap up Chapter 5, the five functionalities of red ginseng are not separate. Smooth blood circulation stabilizes the nutrient supply to the brain, antioxidant activity protects nerve cells, and the adaptogenic action of fatigue improvement reduces the burden on the brain. The five are parts of a single connected health care picture.

When choosing a product, the standard is always the same. Check the health functional food label, the functional phrase, and the ginsenoside content directly on the label.
