Why You Need Vitamin K2

Vitamin K2 MK7 120 30 Capsules

Both vitamins K1 and K2 ensure healthy blood clotting, preventing excessive bleeding and bruising when blood vessels get injured. But recent research suggests that they play different roles in other aspects of our health, with vitamin K2 adding health benefits independent of K1.

However, there is not yet a recommended intake set specifically for vitamin K2. You should get between 90 and 120 micrograms of vitamin K â but this requirement is based on the vitamin K1 needed to prevent bleeding.

Scientists studying vitamin K2âs effects suggest its benefits come with a daily intake of between 10 and 45 micrograms. But in the average diet, about 90% of the vitamin K consumed is K1.

Getting vitamin K2 in our diets supports:

Heart Health

Vitamin K breaks down calcium in our bodies, and this effect helps prevent hard deposits from forming in artery walls. Smooth and flexible blood vessels ensure healthy circulation, reducing the risk of harmful blood clots and heart disease.

This effect may come from vitamin K2 alone, however. Studies show that a personâs risk of dying from heart disease falls by 9% for every 10 micrograms consumed a day, but found no association with K1 intake.

Strong Bones

Our bodies need calcium to build and maintain bones. When it breaks down calcium in our bodies, vitamin K2 activates a protein that helps the mineral bind to our bones to do its job.

Anticancer Properties

Researchers have found that vitamin K2 may slow or stop cancer cell activity.

Is Mk4 Better Than Mk7

Menaquinone-4 and Menaquinone-7 are subtypes of Vit K2. MK-7 shows the highest activity in humans than MK4.

A study was done to investigate the bioavailability of MK4 and MK7. It revealed that MK7 was better absorbed and reached a maximum level within 6hrs. In addition to that, MK7 was detected up to 48hrs .

These findings concluded that MK7 was a greater contributor to the effects of vitamin K2 in the body.

Interaction Of Vitamin K2 And Vitamin D3

Vitamin K2 should always be taken in conjunction with vitamin D3, as the two substances work together and promote bone formation. There are scientifically substantiated indications that calcium, without a sufficiently high level of vitamin K2, can only to a limited extent help to preserve healthy bones.Vitamin K2 should always be taken in conjunction with vitamin D3, as the two substances work together and promote bone formation.

Not Getting Enough Vitamin K Hurts Bone Health

Several observational studies have found that inadequate intake of vitamin K is linked to low bone density and increased risk for fractures.

A study that analyzed data from the large Nurses Health Study found that women who consumed less than 109 micrograms of vitamin K per day were more likely to break a hip.

A study of participants in the large Framingham Heart Study also showed a link between low vitamin K intake and increased risk of hip fractures. This study also showed an association between low dietary intake of vitamin K and low bone density in women.

An adequate intake of vitamin K is considered to be 120 mcg for men and 90 mcg for women. A true vitamin K deficiency, which is marked by an inability of blood to clot normally and easy bruising, is rare. Most people can avoid a deficiency by getting enough vitamin K in their diet, says Dr. Deal.

Vitamin K2 Is The Glue That Helps Calcium Stick To New Bones

If you think about reinventing yourself, you probably focus on changing your hairstyle or embarking on a new career. But on the inside, your body is always getting a fresh start. It continually renews itself, day in and day out.

The bones that give you stability, which seem solid and fixed, are actively broken down and rebuilt constantly as part of your bodys normal processes. Your old bones are broken down as your body pulls calcium or other nutrients from them when needed . Meanwhile, the micronutrients from your diet come in to replenish whats been lost.*

To support the bodys ability to rebuild solid, strong bones, your body need to maintain the right balance of all the nutrients needed to complete the remodeling process. So, regular intake of those nutrients is vital for a steady supply.*

You need plenty of calcium, magnesium, vitamin D, and vitamin K. Regular use of USANAs Vitamin K2 supplement will help supply plenty of this essential nutrient to help ensure calcium goes where its needed to form and maintain strong, resilient bones.*

Heres how it works.

A number of proteins that support proper bone remodeling are dependent on vitamin K2. One of the main proteins is osteocalcin, which helps establish a matrix, or organizing structure, for bone.

Initially, osteocalcin is released by vitamin D3. But it requires vitamin K2 to be activated. The activation process is critical, because it makes the calcium stick to and be incorporated into the bone.*

What Is Vitamin K

Vitamins are nutrients that help to support proper body functions, and every different vitamin plays a special role in the body.

Vitamin K, a vitamin found in certain foods and synthesized by gut bacteria, plays a special role in the process of blood clotting and bone formation.

Discovered in 1929, major breakthroughs in vitamin K research are still happening.

For example, important amino acids and vitamin K-dependent proteins that linked the vitamin to bone health were not discovered until the 1970s, and more dependent proteins continue to be discovered with the latest discovery occurring in 2008 according to the published history of Vitamin K research.

Vitamin K is a group of compounds, with the most common known as vitamin K1 and K2 according to Oregon State University. Vitamin K1 is found in some vegetables and leafy greens, while vitamin K2 is mostly found in meats, eggs, cheeses and is synthesized by intestinal bacteria. Some of the best vitamin K foods include asparagus, broccoli, spinach, beans, soybeans, eggs, strawberries, and meat.

Do We Need To Take Vitamin K2 With Vitamin D3

Both Vit D and K2 are fat-soluble vitamins. Both play a central role in calcium metabolism. Vitamin D3 ensures that calcium is absorbed easily from the food while K2 activates the protein osteocalcin, which integrates calcium into bone and prevents calcium from being deposited elsewhere.

Many animal and human studies suggest Vit D3 has a positive effect on the metabolism of Vit K2 and also promotes K-dependant bone proteins , .

They work synergistically for bone and cardiovascular health.

Yet, there are a few studies that have not observed any such synergistic effect of combining Vit D and K2 together .

Aggregating all the evidence regarding a combined vitamin D and K supplementation, the majority of the studies found beneficial effects.

    Can Vit K2 Be Given To Children

    Children and adolescent bones grow and develop most intensively. Up to 90 percent of peak bone mass is acquired by age 18 in girls and by age 20 in boys. Vit K2 is required to activate osteocalcin, the protein needed for bone-building cells. A 2014 study clearly showed that the levels of osteocalcin in children are 8-10 times higher than in adults, so VIt K2 is required more .

    A controlled trial conducted in the Netherlands demonstrated that a modest supplementation of MK7 helped increase the level of K2 in the blood and the bioactivity of osteocalcin .

    The Benefits Of A Vitamin K Supplement

    Vitamin K2 has several functions in the body, but food sources are somewhat limited, and foods that are rich in this important nutrient have a relatively low presence in the typical Western diet. Humans have the ability to convert vitamin K1 into vitamin K2, but this is a metabolically inefficient process. Certain beneficial bacteria that naturally reside in the human digestive system synthesise vitamin K2, but the use of antibiotics and an imbalance in the microflora of the gut can disrupt the bodys ability to manufacture vitamin K2 for itself.

    Simply Supplements BioGoldTM Vitamin K2 provides a reliable and convenient source of vitamin K2, helping to ensure an adequate intake. Current advice on vitamin K requirements for adults is to maintain a daily intake of 1mcg per kilogram of bodyweight, and this product easily fulfils this criteria.

    The 6 Best Vitamin K2 Supplements of 2021

    Vitamin K activates proteins that play a role in blood clotting, calcium metabolism and heart health.

    One of its most important functions is to regulate calcium deposition. In other words, it promotes the calcification of bones and prevents the calcification of blood vessels and kidneys (

    Therefore, anything that can reduce this calcium accumulation may help prevent heart disease.

    Vitamin K is believed to help by preventing calcium from being deposited in your arteries .

    In one study spanning 710 years, people with the highest intake of vitamin K2 were 52% less likely to develop artery calcification and had a 57% lower risk of dying from heart disease .

    Another study in 16,057 women found that participants with the highest intake of vitamin K2 had a much lower risk of heart disease for every 10 mcg of K2 they consumed per day, heart disease risk was reduced by 9% .

    On the other hand, vitamin K1 had no influence in either of those studies.

    However, keep in mind that the above studies are observational studies, which cannot prove cause and effect.

    The few controlled studies that have been conducted used vitamin K1, which seems to be ineffective .

    Long-term controlled trials on vitamin K2 and heart disease are needed.

    Still, there is a highly plausible biological mechanism for its effectiveness and strong positive correlations with heart health in observational studies.

    Osteoporosis which translates to porous bones is a common problem in Western countries.

    Other Vitamin K2 Benefits Include:

    • Vitamin K2 is good for heart health

    Vitamin K2 helps to direct calcium to the bones and prevent it from being deposited where it shouldn’t be, for example arteries and organs, where it can cause harm.8 According to The Rotterdam Study research, in which men were studied for more than 15 years, the highest intake of Vitamin K2 was linked with a lower risk of heart-related issues, including cardiovascular disease, and cardiovascular disease mortality.9

    • Its good for bone health

    Vitamin K3 activates the proteins that help regulate calcium deposition. This means that it supports the calcification of bones and prevents calcium deposits from forming in the blood vessels.10 A study of Japanese postmenopausal women, who ate Natto, found that they experienced lower bone loss over time.11

    • And dental health too

    Due to the fact the protein thats needed to build strong teeth, osteocalcin, is the same one activated by Vitamin K2 to regulate bone calcification. However, its important to flag here that research in relation to this particular benefit is limited at present.12
