Tackling vitamin K2 and folate deficiencies essential for senior’s brain health, study suggests

18 Jul 2024 --- Research spotlighted by Gnosis by Lesaffre reveals that key nutrients most frequently associated with improved brain function are vitamin K and folate (vitamin B6), with lutein, zeaxanthin and several minerals also shown to be important. The study looked at the cognitive performance of men and women over the age of 60.

“Current research has illuminated the potential necessity for a personalized approach to combating cognitive decline associated with aging, emphasizing the pivotal role of nutrients in sustaining a healthy brain,” says Jean-François Jeanne, substantiation and applications manager at Gnosis by Lesaffre, supply partner of Pharmavite, the US company that conducted the study.

“Pharmavite’s analysis illuminates how nutrient intake can impact cognitive abilities, especially vitamin K2 and folate, providing a powerful incentive to enhance multivitamins and other nutritional products with scientifically proven amounts of K2 and folate, such as MenaQ7 and Quatrefolic,” he adds.

Study findings
The cross-sectional study published in BMC Nutrition used data from the US National Health and Nutrition Examination Survey (NHANES) collected between 2011 and 2014. The participants’ cognition was evaluated using a cognitive function test and valid depression score data. The research team took their nutrient intake into account in order to determine potential association with cognitive performance and depression.

Current research has illuminated the potential necessity for a personalized approach to combating cognitive decline associated with aging.The increased intake and adequacy of several different nutrients from food were shown to be linked to improved cognitive function in both males and females, with vitamin K and folate shown to be the most potent.

Concerning depression, results differed by gender. While the effects of nutrition on males were not observed, in women, more optimal nutrition and intake of vitamin K and folate clearly resulted in improved depression scores.

Yet, adequate intake of vitamin K and folate is rare, with data from the NHANES 2003–2006 survey revealing that more than 75% of the US population does not receive the amounts of vitamin K the human body needs. Many US adults were also shown to be in need of folate supplementation even with mandated folic acid fortification.

Vitamin K2 is the predominant form of vitamin K in the brain, with higher levels leading to improved cognitive performance and a healthy vascular structure within the brain.

Recently, Gnosis by Lesaffre partnered with SunWay Biotech to release the MenaQ7 vitamin K2 supplementation, which has been shown to improve arterial elasticity, also crucial for optimal brain function.
