MenaQ7® K2 Study Validates Inflammation Benefits

MenaQ7-inflammation-benefits

Exciting new evidence confirming K2 as MK-7 modulates immune and inflammatory biomarkers.

 

Journal of Medicinal Food has published a new study that successfully tested and confirmed the role of vitamin K2 as MK-7 (menaquinone-7; MenaQ7® provided by ex-NattoPharma) in modulation of the immune and inflammatory biomarkers.

 

The study, “Inhibition of TNF-a, IL-1a, and IL-1b by Pretreatment of Human Monocyte-Derived Macrophages with Menaquinone-7 and Cell Activation with TLR Agonists In Vitro,” is significant because it confirms another mechanism by which vitamin K2 supports cardiovascular health by impact markers of inflammation.

 

“Chronic inflammation is considered an underlying pathology of many diseases that remain poorly understood and treated,” the researchers wrote. “Cardiovascular disease (CVD), a leading cause of mortality in the world, is not only considered as a disorder of lipid accumulation, but also as a disease characterized by low-grade inflammation of the endothelial cells and an inappropriate healing response of the vascular lining.”

 

The commonly recognized function of vitamin K is a cofactor for c-glutamyl carboxylase, an endoplasmic enzyme involved in the posttranslational carboxylation (activation) of proteins with glutamic acid (Glu) residues into c-carboxyglutamate (Gla). With the carboxylation of glutamic acid residues on the protein substrate, a negative chemical group is formed that attracts and binds positively charged calcium cation. Vitamin K2, in particular, is responsible for carboxylation and activation of osteocalcin, which is essential for physiology of bone-building cells, osteoblasts. Vitamin K2 helps in carboxylation and activation of another protein besides osteocalcin, that is, matrix GLA protein (MGP), important for elasticity and prevention of calcification of blood vessels.

 

To that end, researchers evaluated high-purity natural vitamin K2 (98.4% menaquinone-7, MK-7, as MenaQ7) in vitro for its potential to inhibit gene expression and production of pro-inflammatory markers by human monocyte-derived macrophages (hMDMs) from two sources (hMDMs and THP-1).

 

The anti-inflammatory mechanism of vitamin K2

 

The results showed that the MK-7 form of vitamin K2 is able to dose- dependently inhibit TNF-a, IL-1a, and IL-1b gene expression and protein production by healthy hMDMs in vitro. According to the researchers, “In view of these encouraging findings on the anti-inflammatory properties of MK-7, we plan to test additional biomarkers of immune and inflammatory response in this form of vitamin K2 in vitro. This work may elucidate the anti-inflammatory mechanism of vitamin K2 and establish the potential biomarker targets in clinical testing of the role of MK-7 in the cardiovascular health as well as other chronic degenerative conditions.”

 

“All of the work showing the efficacy of MK-7 inhibiting cardiovascular and soft tissue calcification is recognized to the extent that scientific experts continue to explore new benefits and mechanisms,” says Hogne Vik, ex-NattoPharma chief medical officer. “These findings are very exciting and promising, and we are thrilled that we could offer the research team our vitamin K2 material – providing another piece of evidence that MenaQ7 is a clinically validated ingredient delivering true benefits for human health.”

MenaQ7 study with children

45 mcg per day of vitamin K2 was shown to support the needs of healthy bones in children

Growing Strong Bones

Childhood is the most essential period for developing and building healthy bone mass.
However, research shows children have 8 to 10 times higher levels of inactive osteocalcin, which means they are not optimally building the bone mass they require during this period.[3]

In turn, today we see an increase in low-energy fractures in children. Thankfully there is a way to mitigate this situation.

Studies show that children who have optimal levels of Vitamins K2 and D3 have fewer bone fractures than children with lower status of these two vitamins. [4,5]

MenaQ7® is the only Vitamin K2 on the market proven to benefit bone health in children.

MenaQ7® study show

180 mcg per day of vitamin K2 maintain bone health in postmenopausal women

Well-Being in Times of Change

It is well recognized that women approaching and going through menopause are prone to develop weaker bones.

During this period, hormonal changes lower oestrogen levels, leading to bone loss and increased fracture risk.

Compromised bone health is estimated to affect 200 million women worldwide. Supporting bone health in women during this period of life is growing in importance, particularly as an ageing population seeks to maintain their quality of life.

The combination of Vitamins K2 and D3 is shown to have a more beneficial effect on this demographic’s bone strength than either vitamin taken alone.[5]

MenaQ7® is the only clinically proven K2 to deliver on the promise of maintaining bone health in postmenopausal women.[2]

Supporting Mothers for Healthy Babies

Pregnancy is a time of extraordinary change and the WHO estimates 20-30% of pregnant women suffer from some kind of vitamin deficiency. Post-natal supplements are important for many women during this period of their lives to ensure not only their health, but their babies as well.

In particular, pregnant women are advised to increase their calcium levels to support the growing babies’ bone and teeth – and to maintain the mothers own bone mass, which is depleted during pregnancy and nursing.

Research shows that women's bone metabolic status significantly changes over the period between pregnancy and during nursing [6], and as much as 50% of newborns are K deficient. Incorporating Vitamins K2 with D3 in post-natal supplements would benefit both mother and child through their combined optimization of calcium.

MenaQ7® study show

180 mcg per day is beneficial for bone and cardiovascular health.

Do What You Love Longer!

Calcification is believed to be an inevitable and unfortunate result of aging, but studies show that arterial calcification is, in fact, an actively regulated process where Vitamins K2 and D3 play a critical role.

In 2020 the ageing population (people over the age of 65) grew to approximately 727 million. Supporting bone and heart health is vitalto ensure quality of life as we age.

A 2013 study [8] evaluating the cardiovascular effect of Vitamin K2 (MenaQ7®) plus Vitamin D or Vitamin D alone showed more beneficial results when the two nutrients were combined than when D was taken alone.

MenaQ7® is the only clinically Vitamin K2 as MK-7 proven to reduce arterial stiffness in adult populations.[9]

Active Lifestylers

The bone and joint market is still expected to be driven by aging populations, but trends like Healthy Aging and Fitter for Longer open the market for younger demographics. Since 2000, views have drastically evolved about the importance of staying active and the role bone/joint health plays in one’s ability to do so.

Bone fractures are an obvious hindrance to staying active. In fact, every 3rd woman and every 5th man over the age of 50 will experience osteoporotic fractures. It is also worth noting that young female athletes have higher fracture risks than male counterparts.

Knowing the intricate balance between Vitamins D3 and K2, and its combined benefits for bone and heart health, a product that aims to support active lifestylers should incorporate both.
