Is it necessary to provide infants with D3 K2 supplements? D3 and K2 play crucial roles in the development of a child. Insufficient levels of D3 and K2 can lead to various health issues such as delayed growth, weakened immune system, impacting bone health, and height.

Understanding the Roles of Vitamin D3 and K2 in Infants
For a long time, many have been aware of the importance of supplementing D3 K2 for infants. So, what are the actual roles of these two vitamins for infants?
The Role of Vitamin D3 in Infant Development
Vitamin D3 is crucial for the growth of children. Thanks to this vitamin, a child's body will absorb the necessary calcium from their food. Therefore, vitamin D3 plays a vital role in the development of bones and teeth. Insufficient supplementation of vitamin in infants can lead to rickets, a condition affecting the growth and development of bones in young children.

The Role of Vitamin K2 in Infant Development
Why do experts often recommend supplementing D3 K2 for infants together? Scientific studies have clearly shown that vitamin K2 plays a crucial role in the body.

Scientists have pointed out that supplementing vitamin K2 will reduce the risk of cardiovascular events as the child grows. Additionally, it plays a vital role in the nervous system. Thanks to K2, children are ensured better growth and cognitive development in the brain. Researchers have found a relationship between body weight and vitamin K, linking K2 to the metabolism of fat and glucose. As a result, K2 has the ability to reduce the risk of obesity, helping to control body weight more effectively.

When vitamin D3 transports calcium from the intestine to the blood, vitamin K2 then plays a role in continuing to transport calcium into the baby's bones.
