Why does zinc shorten cold duration
Sources:
Zinc can help shorten the duration of a cold by supporting the immune system. According to , studies have shown that taking approximately 90 milligrams of zinc acetate daily can lead to a three times faster recovery rate from colds compared to those not supplementing with zinc. This is because zinc likely plays a role in inhibiting the replication of rhinoviruses (the viruses that cause the common cold) and can enhance immune cell function 1. However, it's essential to use the correct dosage, as insufficient amounts (less than 75 milligrams) may not be effective. It's also recommended to take zinc with food to avoid gastric distress 2. As with any supplement, consulting with a healthcare professional before starting zinc is advised.
