This is Dr. Brownstein's Covid protocol for vitamins, for someone with a significant covid exposure

or beginning to have symptoms: 

Vitamin D3 50,000IU once daily for 4 days then reduce dose to 10,000IU daily

Vitamin A 100,000IU once daily for 4 days then reduce dose to 10,000IU daily

Vitamin C 1,000mg every hour until bowel tolerance (until loose stools develop) for 4 days.

Quercetin 500mg daily

Zinc 50 to 75mg daily (take with food)

Natto-kinase supplement twice daily for about 3-4 weeks.

25mg/day of Liquid Lugol's Iodine for 4 days.

If you start feeling flu-like or have cold symptoms, then get tested and isolate. 

I would pick up the nebulizer and H2O2 and saline solution to have on hand in case of infection.

Sincerely,

Dr. Ola
