Vitamin K: The modern vitamin for healthy ageing

The vitamin K family are less well-known vitamins than most and comprise a group of very important vitamins - vitamin K1 (phylloquinone) and vitamin K2 (menaquinone).

What is vitamin K?

Vitamin K is an essential vitamin that plays two fundamental roles; the protection of bone density and bone strength, which if not supported nutritionally, can lead to osteoporosis and fractures.

This essential vitamin also possesses a critically important wound healing factor, via its blood clotting mechanism. Without vitamin K, we would simply bleed excessively, even when just bruised - making it vital to avoid deficiency.

What foods contain vitamin k?

Vitamin K1 in our diet can be found in leafy greens and some other vegetables.

Vitamin K2 is however, is largely obtained from animal-based foods, such as meats, cheese, eggs, and fermented foods e.g. natto, a traditional Japanese dish containing fermented soybeans and sauerkraut, a fermented cabbage dish.  


How to increase your vitamin K intake?

We can naturally increase our intake of vitamin K by simply eating more green vegetables, but this is mostly vitamin K1 and not K2. Unfortunately, vitamin K2 is much more difficult to get from diet alone.  


What is vitamin K2 good for?

Vitamin K2 helps calcium move into our bones. The accumulation of calcium in our body tissue is called calcification, which normally occurs in the formation of bone. However, excess calcium from our diet can also become deposited in our soft tissues such as the inside of blood vessels and coronary arteries that supply oxygenated blood to the heart. This is exactly where calcium is NOT needed nor wanted as it can lead to atherosclerosis, causing stricture and reduced blood flow.

There is now mounting evidence in many impressive clinical trials showing that vitamin K2 can not only help protect bone strength and reduce fracture rates but also reduce hard calcium-containing plaques on the inside of our arteries.

Vitamin K2 removes the calcium from the inside of our arteries and moves it back into our bones - exactly where it is needed. This has been proven in many mechanistic scientific trials, making K2 a real benefit to our overall cardiovascular system.

Why consider vitamin K supplements?

The highest source of vitamin K2 can be found in fermented foods such as natto and sauerkraut.

These fermented foods are not everyone’s cup of tea, especially here in the UK. Therefore, taking vitamin K2 supplements can be an excellent way of increasing your K2 uptake for both bone health and cardiovascular health too.

The Prime Fifty product range is specifically formulated for the over 50s, capitalising on the benefits of both vitamin K1 and K2, as both bone health and cardiovascular health tend to decrease with age.

Our Strong Bones supplements feature a tailored blend of nutrients, including both vitamin K1 and K2. 

Also, our brand-new Total Health ‘3 in 1’ supplement pack contains a high quality, modern multi-nutrient formulation, using both vitamin K1 and K2 at optimal levels, plus an additional 30 healthy ageing ingredients.
