Supplements to shorten cold

To shorten the duration of a cold, several supplements can be effective:

1. Zinc: Taking 100 milligrams of zinc daily can significantly impact the likelihood of getting or shortening a cold. It's recommended to take zinc with food to avoid gastric distress 1.

2. Vitamin C: Higher doses of vitamin C, around 2 grams per day, can reduce the duration of a cold. In adults, it can shorten the cold by 21%, whereas in children it can decrease it by up to 26%. Prophylactic (preventive) and therapeutic (treatment after symptoms start) vitamin C supplements combined are more effective than therapeutic doses alone 2.

3. Echinacea: Although some people believe in its benefits, scientific support is weak, and excessive use might inhibit the immune system. Echinacea might be reserved for short-term use during high-risk periods or initial cold symptoms, but not for continuous long-term use 1.

These recommendations are based on scientific studies discussed by experts like Andrew Huberman and Rhonda Patrick. Always consult with a healthcare professional before starting any new supplement regimen.
