I encountered a new prescription for influenza in runet recently. It suggested taking high doses of vitamin C at the first sign of flu symptoms: 2 mg for the first two days, followed by 1 mg for the next two days, and finally 0.5 mg for three days. I followed this process several times whenever I became ill, but found it generally useless; I still fell ill just as I would without vitamin C.

I bought this supplement out of curiosity, following a new treatment plan for influenza and respiratory infections. At the first sign of illness, I took 500 mg of Ester-C every two hours, along with zinc and vitamin D3. Remarkably, by the next day, my throat felt better, and I avoided antibiotics. By the third day, I was completely well! This approach truly worked for me and was far faster than any medicine I have taken before.
