Supplemental synthetic hormone D (aka "Vitamin" D) does RUIN your blood vessels completely!

One of the greatest culprits, which does cause low Potassium levels are insane high supplemental, synthetic “Vitamin” D dosages, which do have a devastating affect on your liver's ability to make proper levels of Ceruloplasmin (the KEY! enzyme that makes Copper bio-available!) and therefor low Ceruloplasmin levels (=low bound/bio-available Copper) further have devastating effects on your blood vessels because it is essential to have proper levels of Copper-dependent Lysyl Oxidase working to bring collagen and elastin to those blood vessels.
