it was unclear if benefit was confined to people with lower baseline vitamin D status. Additionally, high-quality case-control and/or cohort studies indicated that vitamin D deficiency is a factor associated with an increased risk of future asthma attacks in school-aged children. Further research ...

D status as “deficient” when serum hydroxyvitamin D (25[OH]D) was lower than 20 ng/mL, and “insufficient” when serum 25(OH)D was 20 ng/mL to 29 ng/mL. Now, the Society “no longer endorses specific 25(OH)D levels to define vitamin D sufficiency, insufficiency, and deficiency....
There is consensus that daily intake of 400 IU of vitamin D can prevent nutritional rickets in infants and children1. However, the skeletal effects of vitamin D deficiency in adults and older adults (aged >65 years), and the potential extra-skeletal effects of vitamin D are more controversial...
Vitamin K, a fat soluble vitamin, is a necessary cofactor for the activation of coagulation factors II, VII, IX, X, and protein C and S. In neonatal period, vitamin K deficiency may lead to Vitamin K Deficiency Bleeding (VKDB). We present the case of a 2
Objectives: We aimed to assess the prevalence of vitamin D deficiency in children (0–18 years old) in a tertiary hospital in Romania between August 2019 and January 2024 and to investigate the role of adequate supplementation in this vulnerable population. Methods: The serum 25(OH)D levels ...
There are various factors that contribute to the development of their deficiency, which might result in or exacerbate various diseases. These nutrients can also interact with vitamin D metabolism and activity. This review discusses the main aspects of zinc, magnesium and vitamin K metabolism and ...
Severe vitamin D deficiency with a 25(OH)D concentration below <30 nmol/L (or 12 ng/ml) dramatically increases the risk of excess mortality, infections, and many other diseases, and should be avoided whenever possible. The data on a benefit for mortality and prevention of infections, ...
