Was posting about this elsewhere, and thought I would mention it here. My DH tried this product and loved it. He felt it cut short an impending cold. He is around a lot of sick people lately and started taking it when he got symptoms. It has a different active ingredient than Airborne, and studies in Germany have shown positive results in regard to bronchitis and other conditions. (Study info per ConsumerLab.com, an independent site I subscribe to that evaluates vitamins and other supplements to determine if they contain the ingredients they claim, how well they absorb, any possible interactions, etc.)
