There are 7 dhatus in our body namely rasa,rakata,mamsa,meda,asthi,Maja and Shukra among which like u said
calcium so its due to asthi,sodium and pottasium due to rasa,iron due to rakta or blood,b6 or
b12 due to mamsa,omega 3 and loss of vitamin C leads to meda loss then Majja and Shukra leads to loss of hair,endurance and ojas too. But you need to tell what all deficiencies have you got after getting your lab tests done properly. And what youre suffering from? If you want to strengthen your body and dhatus then you may take medicines in ayurveda such as dhatupushtikara churna 2gms daily for 7 days or atibala churna for 5 days.
