2021's 10 Best Vitamin K2 MK4
TOP SUPPLEMENTS

Vitamin K rose to prominence in the late 1920s because of its effectiveness at facilitating blood clotting. (See Reference 1) More recently, it has gained attention as a key nutrient that offers numerous health benefits. There are two main types of vitamin K, which are K1 and K2. Of those, vitamin K2 has shown the most potential benefits, particularly its MK-4 variant. Let’s take a look at some of these benefits. (See Reference 2)

Health Benefits of Vitamin K2 MK4

Heart Health

Although calcium offers a range of health benefits, its accumulation around the arteries can contribute to clogging and put the heart at risk. Vitamin K2 has been shown to reduce excessive calcium acclamation around the arteries.

One decade-long study was conducted with almost 5000 subjects and examined whether Vitamin K consumption can help reduce calcium deposits around arteries. The researchers concluded that Vitamin K2 does help promote better heart health.

Another study was conducted with over 16,000 female subjects ranging from 49-70 years of age. The study lasted for 4 years and found a close association with vitamin K2 consumption and promoting better heart health.

Bone health

The elderly are prone to declining bone density with age progression. There’s plenty of research data that links vitamin K2 consumption with improved bone health.

For example, a 2006 meta-analysis of several studies sought to find out what vitamin K2’s impact on bone density was. The subjects during these studies were asked to supplement with K2 MK-4 for at least six months. Researchers concluded that vitamin K2-MK-4 not only improved the subjects’ bone density, but it also brought about a significant reduction in risk of suffering hip and spinal fractures. (See Reference 3)

Skin health

Collagen and elastin are two key proteins that form the basis of the skin and connective tissue and provide strength and elasticity. With age, collagen and elastin reserves get depleted, which causes wrinkles.

A 2007 study found that lack of matrix-GLA (a K2-stimulated protein) can magnify the loss of elastin and speed up the aging process. This means that supplementation with vitamin K2 can help keep the skin stay more elastic and youthful. (See Reference 4)

Athletic performance

There is convincing scientific evidence that suggests supplementing with vitamin K2 can help improve endurance by making the heart work harder.

A 2017 study with 26 male and female athletes looked into this question over an 8-week period. For the first 4 weeks, the athletes were required to take a dose of 300mg of vitamin K2 daily. For the subsequent 4 weeks, the daily dosage was halved to 150mg. (See Reference 5)

Researchers found that the K2 supplementation brought about a significant uptick in the athletes’ heart output. This means their hearts could pump more blood and carry more oxygen and nutrients to muscles, resulting in better endurance. K2 supplementation also facilitated a reduction in lactic acid, a compound that leads to muscle exhaustion during physical exercise.
