I don’t know if it qualifies as a cure but in my experience if one has symptoms of “common cold”(or flu) one day and takes a measured megadose of vitamin D3 the symptoms will be gone in 8 to 10 hours. If one takes a daily D3 supplement of, say, 125 mcg or in the summer gets sunshine on skin every day which practice I have followed for 18 years, one is unlikely to get any cold of flu syptoms in the first place. I did get the CCP flu in early March 2020 and treated it the same way, 3500 mcg (determined by body weight) and approximately 9-10 hours later it was clear.
Yup. My “Covid cocktail” consists of 5,000 iu of Vitamin D3, 50mg of Zinc, and 250mg of Quercitin. I have 100 tabs of 12mg of Ivermectin in reserve.
