Question 1

Does elderberry really help with colds and flu?

Accepted Answer

Yes. A 2019 meta-analysis in Complementary Therapies in Medicine found elderberry supplementation substantially reduced upper respiratory symptoms. It works by boosting cytokine production and preventing viral entry into cells. Take elderberry syrup or lozenges at the first sign of symptoms.

Question 2

How much zinc should I take for a cold?

Accepted Answer

Zinc lozenges (13-23mg of elemental zinc) taken every 2-3 hours within the first 24 hours of cold symptoms can shorten cold duration by 1-2 days, according to a Cochrane Review. Don't exceed 40mg per day, and avoid zinc nasal sprays (risk of smell loss).

Question 3

Does vitamin C prevent colds?

Accepted Answer

Regular vitamin C supplementation (200mg+/day) doesn't prevent colds in the general population but may reduce duration by 8% in adults. However, in people under physical stress (marathon runners, soldiers), it can reduce cold incidence by 50%, per Cochrane data.
