I decided to try supplementing Vit A after reading about its anti-viral proprieties. I take a multi which already contains 5000UI. I seem to be getting a strong reaction. I've taking an additional 25,00UI two days in a row and each time, about an hour later I have strong flu like symptoms and terrible inflammation which is quite surprising. I'm in two minds if this is a good thing or not. It might be an immune activation or an actual reaction. Anyone else experience something similar?
