This is concerning your quest with Calcium.
Have you ever investigated Vitamin K?

''Vitamin K participates in the conversion of 10-12 glutamic acid
residues in precursor coagulation proteins (eg, prothrombin
precursor) to their active forms (eg, prothrombin) by the addition of
carbon dioxide (carboxylation; see Fig. 3-2). This addition increases
the affinity of glutamic acid residues for calcium, which is
essential for coagulation and the modulation of calcium uptake in
bone.''

arteries.''
