Good morning ma'am.
Post viral infection including SARS-CoV2 you might experience some weakness, joint pain, easy fatigue for around 2 weeks , during which you can take some multivitamin supplements.
However its advisable to take natural sources of vitamins like fruits. Also you should include adequate protein in your diet to enhance your immunity.
As far as Becosule z is concerned it has side effects too , though less frequently like,
.Headache
Mild transient diarrhea
Congestive heart failure
Rashes, skin irritation
Cramps
Frequent urination
Chest pain
Muscle weakness
Transitory exanthema (skin eruption)
Dizziness.
So I would advice to avoid consuming of your own for more than 2 weeks.
Also its not required untill otherwise proven by lab test or asked by a practioner.
Stay safe , healthy and happy
Regards
