I am a researcher, thus I can suggest this curement.
For coronavirus curement, simple cough, severe bronchitis or pneumonia I can suggest you try using these ingredients. This curement was developed by me.
I suggest using this:
a) 30, 000IU vitamin D per day (notice here the dosage is 30, 000IU and not 3000IU) for three days (in case symptoms persist, take for another two days).
b) 600mg Magnesium Citrate per day
Probably you will see amazing results, since already in two different occasions, it eliminated cough in 2 days and on another occasion it eliminated cough in three days.
Use this curement completely on your own responsibility or inform your doctor as to supervise supplementation.
