Hi wlelcome - I understand your concern . For
vitamin D deficceincy you have to conmsume more amount of this.. All animal foods like2 pcs eggs, fish 100gm,some sea foods, chicken ,lean meat etc atre helpful.. also take some morning or light level of sunlight which is the one of the best source of vitamin D to make strrenthen bones/cartiledges. etc.. Avoid Ultra violet rays but best wuality sullight good. also all green s green leav\fy vegetables,soya, all legumes are also helpful. cod
liver oil also good.
