Perhaps there’s a reason your mother touted the benefits of vitamin C whenever you felt like you were coming down with something. According to Dr. Silvia Robalino, a board-certified internal medicine doctor at HCA Florida Mercy Hospital, “We experience inflammatory responses in our body when we have a common cold because the immune system is typically attacked by a virus,” adding that vitamin C is vital to proper immune cell function and the overall health of the immune system (via Health).
Vitamin C has been linked to reducing the length of a cold, per a 2013 study. Although there’s not much by way of data to support the claims of a cough stopping because of vitamin C, there is a 2021 study published in Frontiers in Immunology that talks about the use of citrus juice to help combat inflammation in the body.
However, Dr. Taz Bhatia, a professor of integrative medicine at Emory University, had something different to say about orange juice, per Prevention. “It [orange juice] contains citric acid, which irritates the lining of your already-inflamed throat,” explained the doctor. This is why TikTok trends can be riskier than you realize: There’s always more than meets the eye when it comes to such viral health hacks. But what about the other ingredients?
