Has anybody else done grape seed extract..it is more portent than vitamin C and I've been doing it for the last 2 years and I'm not as sick as I usually am! Wondering if other people have tried the same for allergies and asthma. I still get sinus infections and allergy issues but nothing like I used to. Anybody else try this? For me at least, it's helping me out…I used to have so many sick days from work, now not as much!
