We take vitamins regularly too. We eat a lot of green and orange vegetables and fruit. Not picky eaters either. The more defenses I have the better I feel about it. I don't trust any one defense for any disorder or disease.Does everyone on here get the flu shot? I didn't. I've been taking vitamins religiously, thinking if I get sick it will help me fight it off. DH got the flu shot almost 3 weeks ago and has been fighting flu symptoms since. I know it doesn't mean he got it from the shot. He's on antibiotics, inhaler and Robitussin now.
