Vitamin K2

In the world of nutrition, some vitamins steal the spotlight more than others. Vitamin C for immunity, vitamin D for bone health – these are the usual suspects. But lurking in the shadows, yet equally crucial, is vitamin K2. Often overlooked, this unsung hero plays a pivotal role in our overall health and well-being.

Understanding Vitamin K2

Let’s start with the basics. Vitamin K2, a lesser-known sibling of Vitamin K, is a fat-soluble vitamin. Its primary function? Regulating where calcium ends up in the body. In essence, it acts as a traffic cop, directing calcium to where it’s needed most – like your bones and teeth – and away from where it shouldn’t be, such as your arteries.

Health Benefits of Vitamin K2

1. Bone Health:

Vitamin K2 works hand in hand with Vitamin D and calcium to keep your bones strong and healthy. By ensuring that calcium is properly deposited in bones, it helps prevent osteoporosis and fractures.

2. Heart Health:

By preventing calcium buildup in arteries, vitamin K2 reduces the risk of arterial calcification, which is a leading cause of heart disease.

3. Dental Health:

Strong teeth need more than just brushing. Vitamin K2 assists in the proper mineralization of teeth, promoting dental health and preventing decay.

4. Cancer Prevention:

Some studies suggest that vitamin K2 may play a role in preventing certain types of cancer, including prostate and liver cancer, though more research is needed in this area.

Food Sources of Vitamin K2

Here are some food and natural sources of vitamin K2:

1. Fermented Foods:

Fermented foods are excellent sources of vitamin K2 as they undergo a fermentation process that increases the vitamin’s bioavailability. Examples include natto, a traditional Japanese dish made from fermented soybeans, and fermented dairy products like cheese and yoghourt.

2. Animal Products:

Animal products are rich in vitamin K2, particularly those derived from grass-fed animals. This includes liver, egg yolks, and meat from animals like beef, pork, and chicken.

3. Fatty Fish:

Certain fatty fish contain moderate amounts of vitamin K2. Opt for varieties like salmon, mackerel, and sardines to boost your intake.

4. Cheese:

Cheese, especially hard and aged varieties like Gouda, Swiss, and cheddar, is a good source of vitamin K2. The fermentation and aging process contribute to higher levels of this nutrient.

5. Egg Yolks:

Egg yolks contain vitamin K2, making them a convenient and versatile option for increasing your intake. Choose pasture-raised or free-range eggs for added nutritional benefits.

6. Chicken Liver:

Chicken liver is not only a good source of protein but also provides a healthy dose of vitamin K2. Incorporate it into your diet through dishes like pâté or stir-fries.

7. Natto:

Natto, a traditional Japanese food made from fermented soybeans, is one of the richest sources of vitamin K2. While its strong flavor may not appeal to everyone, it’s worth trying for its nutritional benefits.

Incorporating these foods into your diet can help ensure an adequate intake of vitamin K2, supporting various aspects of your health, including bone, heart, and dental health.

Signs and Symptoms of Deficiency

Unfortunately, many people are deficient in vitamin K2 without even realising it. Some common signs and symptoms include:

• Easy bruising or excessive bleeding
• Poor dental health, such as frequent cavities or tooth decay
• Weak or brittle bones
• Cardiovascular issues, like arterial calcification or heart disease

Ways to Determine Deficiency

If you suspect you may be deficient in vitamin K2, there are a few ways to confirm:

1. Blood Tests:

A simple blood test can measure your levels of vitamin K2. However, it’s important to note that this isn’t always standard practice in routine blood work, so you may need to request it specifically.

2. Symptom Assessment:

Take note of any symptoms you may be experiencing, especially those related to bone, heart, or dental health. While not conclusive on their own, they can provide valuable insight into your overall vitamin K2 status.

3. Dietary Evaluation:

Since vitamin K2 is primarily found in animal products and fermented foods, evaluating your diet can also offer clues. If you don’t consume many of these foods, you may be at higher risk of deficiency.

In conclusion, while vitamin K2 may not be as well-known as some other vitamins, its importance to our health cannot be overstated. From bone and heart health to cancer prevention, it plays a crucial role in numerous bodily functions. By understanding its significance, recognizing the signs of deficiency, and taking steps to ensure an adequate intake, we can unlock the full potential of this vital nutrient and safeguard our well-being for years to come.
