Vitamin C to stop colds. Your grandma swore by it. Let’s check the receipts.
VERDICT: SKIP IT ❌ (as a cold stopper)
• A Cochrane review (29 trial comparisons, 11,306 people): taking vitamin C regularly did not lower the chance of catching a cold in the general population.
• Exception: in 5 trials (598 marathon runners, skiers and soldiers under heavy physical stress), colds were about halved.
• Taking it regularly may shorten colds a little (about 8% in adults); low confidence it matters much. Starting it after symptoms showed no consistent effect.
• NIH: adults need 75 mg (women) to 90 mg (men) a day; upper limit 2,000 mg (too much can cause diarrhea, nausea, cramps).
🛒 Do this instead: get it from food (citrus, peppers, kiwi, broccoli).
👉 Our pick (better alternative): ARM & HAMMER Simply Saline Daily Care Nasal Spray, 4.5 oz (affiliate) https://www.amazon.com/dp/B0013UU9WK?tag=donia0b5-20
Why saline? It’s a simple drug-free rinse for a dry or stuffy nose during cold season. It won’t prevent or cure a cold. We don’t link vitamin C pills.
