Vitamin C for COVID-19
7th treatment shown to reduce risk in September 2020
 
*, now known with p = 0.000000087 from 70 studies, recognized in 11 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
4,000+ studies for 60+ treatments. c19early.org
Long COVID trial comparing L-arginine + vitamin C with multivitamin treatment (vitamin B1, B2, B6, B12, nicotinamide, folic acid, pantothenic acid), showing significant improvement in symptoms with L-arginine + vitamin C treatment.
This is the 49th of 70 COVID-19 controlled studies for vitamin C, which collectively show efficacy with p=0.000000087 (1 in 11 million).
21 studies are RCTs, which show efficacy with p=0.0012.
relative recovery, 41.4% better, RR 0.59, p < 0.001, treatment mean 8.15 (±1.3) n=869, control mean 13.9 (±2.3) n=521, relative symptom score.
relative recovery, 67.5% better, RR 0.33, p < 0.001, treatment 869, control 521, relative Borg score.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
Izzo et al., 19 Jul 2022, prospective, Italy, peer-reviewed, 21 authors, this trial compares with another treatment - results may be better when compared to placebo, this trial uses multiple treatments in the treatment arm (combined with L-arginine) - results of individual treatments may vary, LINCOLN trial.
