Maybe it’s just me but when I start to come down with a viral infection I run, not walk, to my bottle Vit-C+RoseHips and take 2000 MG, and then 1000 Mg every 4 hrs. I have not had flu or even a cold in I can’t remember when. It knocks a cold or virus before it can take hold. I also take Vit-D3.
Del-immune V works even better than vitamin C.
Its the stuff that saved Russia when Chernoble melted.
Its made from lysed lactobacillus bulgaris.
