Zinc lozenges might help with colds, but it depends on how much zinc you take and what type of zinc it is. Taking more than 75 mg a day works, while less doesn't, and acetate zinc works better than other kinds.

Taking zinc lozenges (like a special candy) right when you start feeling a cold can help you feel better. Using about 80-100 mg per day works best, and taking more than that doesn't give extra benefit.
