The fat soluble vitamins are a great tool to help metabolism and improve overall health. However their oral usage is sometimes hindered by their requirements for ingestion of fat. In the case of vitamin K2 (MK-4) the fat requirement can be large (35g+) and thus inconvenient to implement while on the go or when restricting fat intake for various purposes.
This study claims that taurine improves the oral bioavailability of all fat-soluble vitamins and especially vitamins A and K.
"...In the literature taurine is characterized as a non-specific growth or blood clotting factor, an antioxidant, a membrane protector, or a regulator of calcium ion homeostasis, just as vitamins A, D, E, F, and K are similarly characterized. On the basis of recent finding concerning the relationship between taurine and the aldehyde of vitamin A-retinal (Petrosian and Haroutounian, 1988, 1998; Petrosian et al., 1996), as well as on the basis of data from the literature, we now suggest a hypothesis that taurine promotes the bioavailability of the lipid soluble vitamins A, D, E, K, and F, probably by forming different types of water soluble, easily hydrolyzable complexes. It is quite possible that the ability of taurine to convert lipids and lipid soluble substances into a water soluble state is the key to understanding the unusually wide diversity of biological phenomena associated with taurine."
If somebody can get the article and PM it to me I can post more detailed info such as suggested dosages, etc.
Perhaps it can allow the excretion of fats.
