Vitamins D3 and K2: a synergistic combination for young and old

Vitamins D3 and K2 are individually very important and useful vitamins, but together they reinforce each other and work synergistically. A strong combination that is good for young and old.

Vitamin D

Vitamin D is one of the best known vitamins. It has many positive effects on general health, due to its important role in various processes throughout the body. Especially during the winter months, it is very useful to supply vitamin D with a supplement. The short, dark days mean that less vitamin D is produced in the body. But also on sunny days, such as in summer, it is wise to take vitamin D supplements. It is good for bones, teeth, muscles, the immune system and the absorption of calcium. A shortage can quickly lead to reduced resistance.

Vitamin K

Unlike vitamin D, vitamin K is less well known. Vitamin K, like vitamin D, is a fat-soluble vitamin. There are several forms of vitamin K, including vitamin K1 (filoquinone) and vitamin K2 (menaquinone). Vitamin K1 is mainly found in green leafy vegetables. Vitamin K2 is produced by natural good bacteria and is thus found in natto (soy dish from Japan), meat and dairy products such as hard cheeses.

Vitamin K is mainly known for its necessary function in blood clotting. This is its primary function; vitamin K1 is used in the liver to activate blood clotting. However, vitamin K1 is difficult to absorb.

Vitamin K2, or menaquinone, is gaining popularity. Its effects in various health areas have been confirmed by several scientific studies. In addition, vitamin K2 or menaquinone is much more absorbable than vitamin K1, and it also stays in the body much longer. Unlike vitamin K1, which is transported in the body to the liver, vitamin K2 is also available to other tissues such as bones.

Vitamins D3 and K2: strong together

Vitamins K2 and D3 together contribute to maintaining healthy bones. Vitamin D supports the absorption of calcium from food and therefore improves the calcium level in the blood. So they play a huge role in calcium metabolism.

Important supplement for children

Kind en Gezin recommends that all children from birth up to and including the age of 6 receive 400 IU (International Units) of vitamin D daily. Vitamin D is needed at an early age for normal growth and the development of bones and teeth. In addition, it supports the functioning of the immune system in children.

Especially young children need extra support for their development and bone structure.
