Bone Up on Vitamin K

When it comes to bones, calcium always grabs the spotlight. But there’s another important nutrient working hard behind the scenes to support bone structure and formation.*

Bone Up on Bone Health

Vitamin K

Yes, calcium is crucial. But it takes an array of nutrients to properly support bone health, including vitamin K.*

The term “vitamin K” actually refers to a family of three fat-soluble compounds, K1 (aka phytometadione, phytonadione or phylloquinone), K2 (menaquinone) and K3 (menadione).

What does vitamin K do?

Within the body, vitamin K supports bone health by allowing bone-building osteoblast cells to bind calcium to bones. Without adequate levels of vitamin K, your bones can’t use calcium efficiently or effectively.*

Vitamin K also supports healthy blood vessels, as well as coagulation factors within the blood which help it clot when necessary – to keep that paper cut from bleeding profusely.*

How can I get more vitamin K?

The best dietary sources of vitamin K include leafy green veggies such as kale, collard greens, turnip greens and spinach. Vitamin K supplements also provide a convenient way to support your diet – but be sure to talk to your doctor before taking a vitamin K supplement, especially if you’re taking any medications – those who take blood thinners should not take vitamin K.

      Hi Sue,
      Thanks for your comment! Unfortunately, we can’t give out any medical advice… you’d have to ask a physician, pharmacist or other healthcare professional.

    Atelvia is correct spelling

      Thomas, thanks for your question! MK-7 is a type of vitamin K2 – it stands for Menaquione-7, which is found in fermented foods such as natto. MK-7 is said to be highly absorbable, which is why it’s a preferred form of vitamin K.

    Sorry, but those of us who take blood thinners cannot take Vit. K because it is an anti-coagulant (which blocks the blood thinners) and should be advertised as such!

    I take Bone Up by Jarrow, will vit.k be safe to take along with it ?I have Osteo, but I am improving. P.T.L.

      Hi Lil,
      Bone Up is a great product – it actually already includes natural vitamin K2 as MK-7, the preferred form!

    Thanks for this good info; If you bleed too easily; taking a while to stop or heal this is a good thing to take. I just found out that I have Von-Willebrand’s disease; inherited from a parent. I’ve been taking Vit K with Vit D liquid; just had two teeth pulled and I am doing FINE. I didn’t bleed much; and healed within a few days. I am now going to add K2 as MK-7 or Bone Up….thanks for the great info!!!
