Bone health: calcium and vitamin K2

The health of our bones is crucial to our overall well-being and quality of life. An important aspect of bone health is the adequate supply of various nutrients, especially calcium and vitamin K2. In this article, we'll take a closer look at the role of these two nutrients and explain how they can help maintain strong and healthy bones.

The importance of calcium for bone health

Calcium is a mineral component of our bone structure. About 99% of the calcium present in the human body is found in the teeth and bones. The rest is needed to enable important functions such as muscle contractions, blood clotting or nerve signals.

To maintain optimal bone health, an adequate amount of calcium must be consumed daily. The recommended daily requirement varies depending on age and gender:

– Children ages 1 to 3 need about 700 mg daily
– Children ages 4 to 8 need about 1000 mg daily
– Adolescents aged 9 and over and adults under 50 need around 1000 mg daily
– Women over 50 and men over 70 should increase their intake to around 1200 mg

There are various sources of calcium that can be included in the diet. The most well-known are dairy products such as milk, cheese and yogurt. However, other foods also contain calcium, for example dark green leafy vegetables such as broccoli or kale.

Vitamin K2 and its role in bone health

Vitamin K2 is an essential fat-soluble vitamin that plays an important role in the health of our bones. It helps calcium to be properly distributed and deposited in the right areas.

Vitamin K2 activates a protein called osteocalcin, which is responsible for incorporating calcium into bones. Without sufficient amounts of vitamin K2, incorrect deposition of calcium can occur - either too little is incorporated into the bones or it is deposited in the wrong places in the body.

Vitamin K2 deficiency has been linked to an increased risk of osteoporosis (bone loss) and cardiovascular disease. Adequate intake of vitamin K2 is therefore crucial for strong and healthy bones and general good heart health.

Sources of vitamin K2

The main source of vitamin K2 is fermentation by bacteria in the digestive tract of certain animal or plant species. However, this does not necessarily mean that all foods that contain vitamin K2 have plenty of it.

Some of the best natural sources of vitamin K2 are fermented foods such as natto (a traditional Japanese dish made from fermented soybeans), sauerkraut and other fermented vegetables, as well as some types of cheese and egg yolks.

The amount of vitamin K2 in these foods can vary depending on the fermentation process. It should be noted that plant sources such as natto often have a higher concentration than animal products.

Can you get enough calcium through diet alone?

Getting the recommended amount of calcium solely through diet can be challenging for many people. Some people may have difficulty with lactose or avoid eating certain food groups, such as dairy products or dark green leafy vegetables.

In such cases, nutritional supplements can help meet the needs. They can come in tablet or powder form and contain various forms of calcium compounds. However, it is advisable to consult a doctor or qualified professional before taking any dietary supplements.

Frequently asked questions

1) How much calcium do children need for healthy bones?

For children ages 4 to 8, it is recommended to consume about 1000 mg of calcium per day to maintain healthy bones.

2) Which foods contain a lot of vitamin K2?

Some of the best natural sources of vitamin K2 are fermented foods such as natto, sauerkraut and other fermented vegetables, as well as some types of cheese and egg yolks.

3) Can you get enough calcium through diet alone?

For many people, it can be difficult to get enough calcium through diet alone. In such cases, nutritional supplements can help meet the needs. However, it is advisable to consult a doctor or qualified professional before taking any dietary supplements.

Conclusion

Calcium and vitamin K2 together play a crucial role in maintaining strong and healthy bone health. A balanced diet with sufficient calcium and vitamin K2 intake is important for people of all ages. For people who find it difficult to get enough of these nutrients in their diet, supplemental measures in consultation with a healthcare professional may be a good option.

Regularly checking blood calcium and vitamin K2 levels can also be helpful to ensure you are meeting recommended levels. By doing our own part to strengthen our bones, we can maintain or improve our health and quality of life.
