Vitamin K shows evidence of brain benefits in rats (Alzheimer's disease and other dementia forms benefit from Vitamin K2-MK7)

In a new study conducted in rats, scientists report evidence that vitamin K could help protect against aging-related cognitive declines associated with Alzheimer's disease and other forms of dementia.

"Vitamin K2 demonstrated very promising impact in hindering aging-related behavioral, functional, biochemical and histopathological changes in the senile aging brain," said Mohamed El-Sherbiny, Ph.D.

Vitamin K is a group of compounds that includes vitamin K1, found in leafy greens and some other vegetables, and vitamin K2, found in meats, cheeses and eggs. Previous studies have linked vitamin K with processes involved in brain functioning, and some studies have associated vitamin K deficiencies with Alzheimer's disease and dementia.

The new study elucidates some of the biological pathways through which vitamin K appears to help preserve cognitive functioning. The researchers investigated the effects of menaquinone-7 (MK-7), a form of vitamin K2, in 3-month-old rats, an age at which rats have reached maturity. One group of rats received supplemental MK-7 for 17 months while the other group did not.

The researchers used validated tests including a maze, swim test and sociability test to assess the rats' cognitive functioning and depressive-like and anxiety behavior. These tests revealed that rats that received MK-7 performed better than those that did not. Vitamin K supplementation was associated with reduced evidence of cognitive impairment, depression and anxiety, along with improved spatial memory and learning ability.

In addition to various forms of vitamin K found naturally in foods, vitamin K supplements are commercially available. However, researchers cautioned that more studies are needed to determine whether the new findings translate from rats to humans and to identify the optimal source and dose of vitamin K to reap potential brain benefits. People taking certain blood thinners and other medications are advised to avoid vitamin K supplements and foods rich in vitamin K.

Better start a daily IV infusion of this stuff into BidenIdiot....../s

Mine, from 1990, is the Omniscience mechanical valve which requires warfarin to prevent clots.

The other two on the market were the Bjork-Shiley which had a bad reputation of breaking after installation,
and the pig valve which needed replacement after 10 or so years.
A man I knew in high School had the pig valve placed in his heart. After 10-12 years he needed it replaced, but died on the table.

I understand modern made valves are so much better than those old valves, but mine is like a Timex. Takes a licking and keeps on ticking, for 32 years.

Spinach doesn’t contain ANY k2 at all!

Note that the vast majority of big benefits from vitamin K are from K2 not K1. Very few people would not get enough K1 from a normal diet, but lots of people could benefit from more k2, especially (2-7 and higher.

You could really hurt yourself from heavily spinach consumption! Did you that can cause oxylate kidney stones?

One of the best sources of k2 are cheese, blue is especially high. Pork, fermented high fat milk products are also good like yogurt and kefir. If it is nonfat it has NO k2.

I forgot to mention japanese natto is also a good source of K2

Just made this for dinner using chicken breasts and loved it, so passing it on.
