Taking zinc tablets or syrups at the first sign of a cold may shorten its duration or even prevent it. This finding comes from a meta-analysis led by Dr. Meenu Singh at the Post Graduate Institute of Medical Education and Research in Chandigarh, India.
Key Facts on Colds
Adults experience colds 2-4 times a year, while children get them about 10 times. Cold viruses spread easily through coughing, sneezing, and contact with surfaces like door handles.
Researchers propose zinc as a potential solution. It strengthens the immune system, blocking viruses from the nasal passages and preventing bacterial multiplication, which reduces infection severity.
Study Insights
The review analyzed 15 trials with 1,360 participants. Those taking zinc at symptom onset had milder symptoms and recovered faster.
Further research is needed on optimal dosing and long-term effects. High zinc doses can be toxic—consult a doctor before use.
