Vitamin K is one of the fat-soluble vitamins with two natural types, phylloquinone (K1) and menaquinone (K2), and one synthetic form named menadione (vitamin K3). Vitamin K plays key roles in different physiological functions such as blood coagulation, bone metabolism, and the regulation of ...
Vitamin K is divided into K1 (phylloquinone) and K2 (menaquinone), which have the similar functions but different characteristics depending on their bioavailability and bioactivity1. Vitamin K2, the main storage form of vitamin K in animals, is subdivided into homologues depending on the length of...
Vitamin K is a family of 2-methyl-1,4-naphthoquinone derivatives that includes the naturally occurring menaquinones and phylloquinone. In mammals, the primary function of vitamin K is to act as a cofactor for the enzyme gamma-glutamyl carboxylase (GGCX)1. About 70% of vitamin K absorbed from...
Upon binding vitamin D, the VDR functions as a transcription factor, regulating the activity of over 1,000 different genes.[14] This “genomic” action of vitamin D tends to be slower-acting, requiring the synthesis of new mRNA and proteins to take effect. Vitamin D also works through “...
Vitamins and minerals are organic materials that your body needs to perform its normal functions. You typically get these nutrients from the food that you eat, especially whole, unprocessed foods like fruits andvegetables. Multivitamins are dietary supplements that have a number of vitamins and minera...

Folic acid, along with vitamins B6 and B12, helps metabolize homocysteine and convert it into other substances, thereby reducing its harmful effects on blood vessels. Cancer Prevention: Some studies suggest that adequate intake of folic acid may reduce the risk of certain types of cancer, ...
Vitamin A is an anti-oxidant which has been presumed to act as an anti-infective vitamin in many studies. This study aimed to evaluate the association between vitamin A supplementation and c-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), a
a bound co-factor of photosystem I (PSI)1,4. Eukaryotes also use menaquinones for various functions. In animals, they are necessary co-factors of blood clotting reactions4, but also function as electron carriers in mitochondrial respiration, or lipid metabolism under microaerophilic conditions3,5...
