Should you take Zinc for colds or COVID? (The latest Science)

Dr Susan Oliver and Julie the dog look at zinc and separate the hype from the science. They look at the latest meta-analysis investigating zinc for the prevention and treatment of respiratory tract infections (RTIs), including colds and flu. They also discuss the various roles zinc plays in the human body, signs you could be zinc deficient, foods high in zinc, and zinc supplements. Finally, they look at zinc and COVID.
