You might want to try this remedy; take 3000 mg of Vitamin C along with one 400 I. U. softgel of Vitamin E.
I'm an R.N. And had not heard of this before until a friend of mine in healthcare mentioned a couple of years ago. Apparently Vitamin E has a synergistic effect on Vitamin C. 3000 mg of Vitamin might sound like a lot; but remember C is water soluble, so what your body doesn't use, you'll pee the rest out. Granted Vitamin E is not water soluble, but I only take this concoction when I begin to feel sick. I'll take it as soon as the symptoms begin, then when I go to bed, when I wake up the next morning, and usually one more dose several hours later. I typically don't need to take it more than that as my symptoms disappear and whatever it was that was starting never culminated into a cold or anything else. You can buy Vitamin C where each tablet is 1000 mg; so you only need to take three of them. They're large and granted Vitamin C is kind of bitter, even if they're flavored tablets and the larger ones tend to be more expensive; but I prefer to do that as opposed to taking several of the smaller ones that are a smaller dose per tablet.
Anyone I've mentioned this to by the way, has eventually gotten back with me telling me that this worked for them.
I've only recently returned to nursing full-time as I had been a FT CSI while working PT as an R.N. For 13 years... So I'm still in the process of building up my immunity level. Most people in healthcare, after working full-time for 6 months, will have never been sicker those first 6 months, and then suddenly, it seems you just don't get anything. In the meantime, I'll stick with C & E regimen. It's worked every time without fail so there has to be something to it. I've been using it for about two years now since my friend told me about it.
Thanks for reading, and I hope this works for anyone else who may try it.
