To continue from yesterday’s post, it’s only fitting to explain the other source of vitamins. Water soluable vitamns are the second half of water soluable vitamins, specifically vitamin B and C. There is an additional “water solubilized vitamin”, vitamin E that is naturally fat soluable, but through manufacturing, vitamin E can become a water solubilized vitamin as well.
Water soluable vitamins are absorbed in the small intestine, transported via the portal system, easily oxidized by heat or light and are not stored in the body’s tissues or organs. It’s important to note that B vitamins contain nitrogen.
