"Where do You know about this ? Am just curious... how you discovered this
I would try it, pls tell me the source and where to buy such pure Vit C in Europe I found only acid ascorbic with lemon flavor 1/ 2 KG powder thatís is the purest I found .."
I don't know if the original poster is following this thread, but I can answer for me. My daughter suggested a Vitamin C flush, so I looked it up online. The first link I clicked on said exactly the same thing the opening post did, so either they work for the company that sells that kind or they were so excited by the results they copied and pasted much of the document.
Here's the link to the pdf. They have a phone number at the end to call if you're outside the U.S. It's a few years old, so I hope the number is still correct. https://beyondhealth.com/media/wysiwyg/kadro/articles/vitc-flush.pdf
I just took my 2nd dose of the flush. The vitamin C I'm using is not buffered, but is not bothering me. If you're interested in that (and it is a whole lot less money than the Beyond Health brand), it is NutriVita and I got it from Amazon.com The important thing seems to be that the vitamin C is "L-ascorbic acid".
