A diet rich in vitamin K to reduce the risk of dementia and Alzheimer’s disease

Dementia is a disease that affects cognitive functioning. Symptoms can include memory loss and the ability to function in ways that can interfere with quality of life.
In a new rodent study, scientists investigated how vitamin K can affect the cognitive abilities of aging rats. Researchers have found that the vitamin has the potential to improve cognitive abilities and protect against the risk of dementia.

With age, the risk of developing dementia increases. Dementia is the term given to a group of diseases, the most common of which is Alzheimer’s disease, which affects millions of people. There is currently no cure for dementia, but some medications can relieve symptoms. Additionally, researchers continue to look for ways to reduce the severity of symptoms or prevent the disease from progressing as quickly.

A new study indicates that vitamin K may help protect against “cognitive decline.” The new study, which was presented at the Experimental Biology meeting on April 5, 2022, tested the administration of a vitamin K supplement to rats.

dementia at a glance

Dementia “is a general term for loss of memory, language, problem-solving, and other thinking skills that is severe enough to interfere with daily life. »
Alzheimer’s disease is thought to result from the buildup of abnormal proteins in the brain called amyloid plaques. These can prevent brain cells from signaling as well as before and damage them. There are other types of dementia, and vascular dementia is thought to be caused by decreased blood flow to the brain, which can also damage brain cells.
According to the most recent data, people over the age of 65 have the highest risk of developing Alzheimer’s dementia.

Listed signs and symptoms of dementia include:

– Forget the names of loved ones
– Humor changes
– Inability to recall old memories.
– Difficulty completing tasks
– Has difficulty communicating

Vitamin K in a Nutshell

It is important to get many kinds of vitamins and minerals to stay healthy. One vitamin that plays a role in brain and bone health is vitamin K, which is often found in leafy green vegetables. The aging process is associated with the deterioration of brain function. Vitamin K is a natural fat-soluble vitamin, it protects the brain from the development of Alzheimer’s disease.
There is a recommended daily amount of vitamin K that varies according to age. Eating adequate amounts of vegetables and fruits is good for maintaining normal vitamin K levels. However, supplements are also available to replace natural sources if you are unable to consume them.

Study on vitamin K and dementia

Because vitamin K can affect brain function, the researchers in this study wanted to see how it affects cognitive functioning in rats. The researchers conducted a 17-month trial in rats. One group received a vitamin K supplement and the other did not. The researchers administered menaquinone-7 (MK-7), which the authors say “is an important form of vitamin K2.” The rats underwent a series of cognitive functioning tests throughout the study. According to the authors, they were evaluated “to assess cognitive level, anxiety, and depressive behavior. »
At the end of the study, the rats that received the vitamin K supplements showed reduced levels of cognitive decline, depression, and anxiety. Furthermore, the authors note that these rats experienced “enhanced spatial memory and learning ability.” »

“Vitamin K2 demonstrated a very promising impact in preventing age-related behavioral, functional, biochemical, and histopathological changes in the aging brain,” the study authors state. They also conclude that “the most important implications are for attention to vitamin K in the elderly population and its relationship to Alzheimer’s disease and other age-related neurodegenerative diseases. »

Vitamin K may support brain health.

There are many forms of vitamin K, and they all have different food sources. MK-7 is found in fermented vegetables, and the benefits of consuming these foods are known. They’re great for your gut microbiome, which has a well-established link to cognitive decline.
