High-dose oral Vit C effective on prevention or reducing symptoms of upper respiratory viral infections

Oral Vit C has been reported to reduce viral infections or improve the symptoms or shorten the disease duration like cold or flu. In a 30-day training camp, a group of 1444 young and healthy military recruits in Korea, 695 subjects received high dose oral Vit C (6000 mg daily) and 749 subjects did not receive Vit C. The Vit C group showed a 0.8 times lower risk of getting common cold than the control group[1]. In an earlier study, a group of 463 students between 18 and 32 years of age were divided into 2 groups, the Vit C group of 252 students, when they reported upper respiratory viral infection signs and symptoms, were given 1000 mg of Vit C hourly for the first 6 hours and then followed by 1000 mg 3 times daily. The Control group, when they showed signs and symptoms, were given pain relievers and decongestants. The authors concluded that the symptoms decreased by 85% with the mega-dose Vit C[2].

This is a story about a Wuhan family‘s fight against Covid-19 with Vit C that I personally interviewed and verified. The video attracted 300K views in ~7 days and Youtube took it down.
