The Benefits of Vitamin K for Heart Health

Vitamin K is not a nutrient that many people know or even think about. However, this fat-soluble essential vitamin plays a critical role in your heart health, bone health, and blood vessel function.1 ‡

There are two categories of vitamin K:2

  • Vitamin K1 (Phylloquinone): Found primarily in plants like leafy greens, this form of vitamin K is used by the liver to support blood vessel function.9 ‡
  • Vitamin K2 (Menaquinone): Vitamin K2 consists of several different forms (for example, MK-4 or MK-7). It is primarily found in animal foods or fermented products.9

Vitamin K, especially K2, can help send calcium to your hard tissues — like bone and teeth — instead of soft tissues like your arteries. As a result, it may help support calcium metabolism in your arteries.8 ‡

Vitamin K also acts as a cofactor along with vitamin D for building these hard tissues. So not only does it help with calcium metabolism in your arteries, but vitamin K may also help with the vital task of strengthening bone and
teeth.3 ‡

Recent studies into the benefits of vitamin K for heart health reveal how this essential nutrient supports your heart:

  • Vitamin K may support vascular elasticity.4 5 ‡
  • Vitamin K may also help maintain cytokine balance, an important factor in vascular health.6 ‡

What Are the Best Sources of Vitamin K?

Our dietary intake of vitamin K1 is in general 10 times higher than K2. The good news is our bodies can convert vitamin K1 to vitamin K2. However, your body likely doesn't make enough, so getting it through diet or supplementation is often necessary.8 9

The best sources of vitamin K include:7 8

  • Leafy greens including kale, mustard greens, swiss chard, spinach, and collard greens
  • Cruciferous vegetables including broccoli and Brussels sprouts
  • Lean proteins including natto, pork chops, beef, egg yolk and chicken
  • Organ meats including liver and kidney
  • Dairy including whole milk and hard and soft cheeses such as blue cheese, edam, Jarlsberg
  • Fruits including prunes, kiwi, avocado, blackberries, blueberries, and pomegranate
  • Nuts and legumes including green beans, green peas, soybeans, and sprouted mung beans

While K1 is relatively easy to get from your diet, K2 is more challenging, especially if you limit your intake of animal products. And while natto, a fermented soy product, is one of the best sources of vitamin K2, the texture or taste is an acquired preference for many.9

Supplements do not replace optimal food choices, but they may help you reach ideal daily requirements for vitamin K2.10

The Benefits of Omega-3s for Heart Health

There are several forms of omega-3 fatty acids, but EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are especially supportive for heart health. These two fatty acids are found primarily in fish. While your body can make small amounts of EPA and DHA from other sources, it's a small amount, so food or supplements are needed to get enough.21

Research shows that omega-3 fatty acids may benefit heart health in a variety of ways. One of their functions is to help the body properly transport and metabolize lipids. An extensive review of more than 80 studies found that, on average, omega-3 supplementation effectively promoted healthy lipid metabolism.23 ‡

What Are the Best Sources of Omega-3 Fatty Acids?

The 3 main categories of omega-3 fatty acids are alpha-linolenic acid (ALA), EPA, and DHA. Your body cannot make essential fatty acids and must get this nutrient from your diet.11

Your body can convert ALA into EPA and DHA, but not in the amounts required to meet recommended daily amounts. Along with your diet, one of the best ways to get enough omega-3 fatty acids is from supplements.25

The best sources of omega-3 fatty acids include:25

  • Fish and seafood including salmon, mackerel, tuna, sardines, herring, and other cold-water fatty fish
  • Nuts and seeds including walnuts, chia seeds, and flaxseeds
  • Plant oils including soybean oil, canola oil, and flaxseed oil
  • Fortified foods including milk and dairy milk alternatives, eggs, yogurt, and juice

To support your dietary choices, omega-3 fatty acid supplements may ensure you get the recommended daily amount of this essential fatty acid. As always, discuss any supplements with your healthcare practitioner since they may interact differently with medications and health conditions.25
