Study says MenaQ7® PURE K2 Shown to Protect Against Calcification

MenaQ7® PURE K2 Shown to Protect Against Calcification

MenaQ7® PURE used as source material confirming K2 inhibits muscle damage from calcification.

 

Nutrients, an international, peer-reviewed journal for studies related to Human Nutrition, has approved for publication in September 2015 a new study showing the protective effect inhibiting muscle damage from calcification of Vitamin K2 as MK-7 (menaquinone-7; MenaQ7® PURE provided by ex-NattoPharma) supplementation on cardiovascular calcification.

 

The study, “High-Dose Menaquinone-7 Supplementation Reduces Cardiovascular Calcification in a Murine Model of Extraosseous Calcification,” is significant because it adds to the substantial body of evidence demonstrating the cardiovascular benefits of Vitamin K2 as MK-7, lending further understanding to the mechanism by which it inhibits calcification damage to cardiovascular muscle.

 

“Cardiovascular calcification is prevalent in the aging population and in patients with chronic kidney disease (CKD) and diabetes mellitus, giving rise to substantial morbidity and mortality,” says Dr. Leon Schurgers, associate professor and senior scientist at the department of biochemistry, the Cardiovascular Research Institute CARIM of University of Maastricht (The Netherlands), and lead researcher on the study. “The aim of this study was to evaluate the impact of high-dose MK-7 supplementation on the development of cardiovascular calcification and the impact on cardiovascular function in a murine model of chronic kidney disease characterized by extraosseous calcification.”

 

As it is well documented that kidney disease patients frequently suffer cardiovascular complications like calcification of the aorta and coronary arteries, the scientists applied an in-vivo rat model system for kidney disease.

 

The animals were divided into four groups: Two control groups with intact kidneys and on standard diet with respect to content of Phosphate and Calcium ± supplementation with 100µg Vitamin K2 as MK-7 (MenaQ7® PURE from ex-NattoPharma)/g; and two treatment groups where 5/6 of their kidneys were removed (mimicking kidney patients) receiving a diet with high content of both Phosphate and Calcium ± supplementation with 100µg MK-7/g.

 

After 12 weeks, the animals were examined for calcification of the aorta, the myocardium, and in kidneys, as well as for certain other changes in the tissues. Using a sensitive technique for arterial calcification (atomic absorption spectroscopy), this study shows that high-dose MK-7 inhibits calcification in aorta and in the myocardium – parts of the arterial bed most often affected in kidney patients. MK-7 also normalized the kidney disease-induced high serum phosphate level.

 

Interestingly, a 10-fold increase in matrix Gla protein (MGP) gene expression in the MK-7 supplemented animals was recorded. According to the authors, this is the first time that MK-7 has been shown to affect the synthesis of MGP in the vascular wall – and not only locally in the arterial wall. This indicates an increased amount of MGP available for activation to inhibit calcification.

 

Decreasing cardiovascular calcification and aortic alkaline phosphate tissue concentrations

 

The researchers stated that MK-7 supplementation inhibited cardiovascular calcification and decreased aortic alkaline phosphate tissue concentrations. The effect of MK-7 was – at least in part – mediated via MGP and subsequent inhibition of ectopic calcification. Since vitamin K has no reported side effects, it seems a promising therapeutic agent for CKD patients, the researchers concluded.

 

“Ex-NattoPharma has enjoyed a long-standing R&D program with the University of Maastricht and CARIM with the specific goal of understanding and validating the benefits of Vitamin K2 as MK-7 for human health,” says Hogne Vik, ex-NattoPharma CEO. “This study is monumental because it shows that our MenaQ7 Vitamin K2 protected smooth muscle cells from calcification. Being able to provide the researchers with our new nature-identical MenaQ7 PURE to add to our growing body of clinical validation marks a true milestone for us.”

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.
