Several factors affecting vitamin D and its active form absorption and storage

  • acidity of stomach (not significant effect)
  • cytopathic effects of viruses
  • cytopathic effects of bacteria

where the last two reasons can be some reasons which may explain why vitamin D should be administered with bread; to make a surface covering around out vitamin D molecules. Probably, the fibers also work in some short of transport media. They can also partially explain why big dose of vitamin D does not last long time in the normostenic body.

Summary of procedures in administrating vitamin D orally

  • with bread (carbohydrates; fibers) - possible protection, better transportation and more to absorbtion
  • with oils (fat metabolism could help in destroying extra free radicals; but I see no other sense in administrating vitamin D with fish oils)
  • daily (not weekly)

Why does the lipid-soluble vitamin D not last in the body long time?
