Learn About Vitamin K – Including Beneficial Foods with Vitamin K

March 25, 2019

We all have different needs for food, vitamins, rest, exercise,

stress tolerance, or ability to handle toxins.

When we talk about important vitamins and minerals, oftentimes vitamins like B, C, and D tend to get the most attention. Yet, the body needs more than two dozen vitamins and minerals every day to function optimally. While there are certainly some which are more critical to important bodily functions than others, the roles of many less frequently discussed vitamins are largely overlooked.

In particular, vitamin K is a vitamin that tends to go under the radar. The reason it’s so underrated may stem from the fact that vitamin K deficiencies are relatively rare. With that said, taking in anything lower than an optimal amount of vitamin K could impair your health in the long run and might even contribute to a higher risk of developing heart disease. [1]

Below, discover just how important vitamin K is in keeping you healthy and what you can do to prevent a deficiency in this essential nutrient.

The Role of Vitamin K

Although its role is understated compared to that of other vitamins, and while it is seldom discussed, vitamin K also supports many crucial functions throughout the body. For one, this vitamin is necessary for proper blood clotting. For another, it contributes to calcium accumulation within the bones alongside vitamin D. While vitamin D is responsible for improving the absorption from the calcium we take in via diet, it can also take calcium from the bones as needed when dietary calcium is inadequate.

Role of Vitamin K

Vitamin K tends to be underrated since a deficiency of this vitamin is rare. However, it does play an important role in: 

  • Bone health
  • Cognitive health
  • Heart health
  • Blood clotting
  • Protects against hypercalcemia

This is where vitamin K comes in: the nutrient can activate osteocalcin to promote the accumulation of calcium in bones and teeth to prevent against loss. In fact, the NHS shows a 30% reduction in hip fractures in women who take 110 micrograms of vitamin K or more per day, and women who ate one serving of leafy greens per day (a rich source of vitamin K) had a 50% reduction in hip fractures compared with those who consumed one serving per week. [2]

Additionally, vitamin K prevents calcium buildup in the kidneys and blood vessels. It can also protect against hypercalcemia, a condition in which the blood’s calcium levels are above normal. This presents serious health hazards like excessive calcium; too much of the nutrient can weaken bones. It may also lead to kidney stones and interfere with organ functionality, including that of the heart and brain. [3]

Vitamin K Deficiency

A vitamin K deficiency, although rare, can have serious implications. Deficiencies in this vitamin have been linked to blood vessel calcification, in which calcium builds up in the arteries causing them to become stiffer. This poses a significant risk for cardiovascular health. Vitamin K deficiency can also prevent the body from producing proteins needed to help the blood clot. When this happens, the risk of excessive bleeding increases.

A vitamin K deficiency is most likely to occur in infants and adults who take medications or have medical conditions which inhibit absorption. The RDI for K2 is 120 micrograms in males and 90 micrograms in females. This may be difficult to achieve through diet alone and, for this reason, it’s recommended to take K2 with D3 to promote proper calcium levels within the body.

Foods with Vitamin K

Foods with vitamin K include leafy greens and even some garnishing, Some fruits and cruciferous vegetables are foods with vitamin K

Vitamin K1 is found mostly in dietary sources and is converted into K2 within the body. Vegetable sources of vitamin K include:

  • Leafy greens:
    • Kale
    • Spinach
    • Mustard greens
    • Others
  • Leeks and cruciferous vegetables:
    • Broccoli
    • Cauliflower
    • Brussels sprouts
    • Others
  • Even certain types of garnishing and herbs can be used for vitamin K intake:
    • Capers
    • Parsley
    • black peppercorns
    • Others
  • Fruit sources include:
    • Blueberries
    • Kiwi
