With mitral valve prolapse should one take just magnesium or calcium magnesium? and how much?

Prolapse: There is no great reason to take extra electrolyte unless for specific reason.

Copper?: In years past theory held mpv attendant with copper deficiency. I have not seen any follow up. I think we should be perspective to note if women with joint hypermobility syndrome (jhs) & looser ligmentous tissue have an higher incidence of mpv. The brighton scale is criteria for diagnosis jhs & includes being able to lock knees & touch palms to floor & oppose thumb to radial aspect of forearm.
