Dietary Intake and Supplement Use of Vitamins C and E and Upper Respiratory Tract Infection

Abstract

The present study is the first observational study to suggest that intake of vitamin C from food is sufficient to lower the risk of URTI among women. In addition, it appears that supplement use of vitamin E and vitamin C may reduce the risk of URTI among men, who overall had a lower intake of vitamin C from food than women.

An invitro study of synergetic effect of Vitamin C on antimicrobial activity of antibiotics against isolated from respiratory samples

“…11 Vitamin C supplementation is also widely given during respiratory tract infections by various clinicians. 12 Vitamin C supplements reduces the duration and symptoms of the upper respiratory infections in regular supplementation trials and in therapeutic trials. 13 The treatments against infections caused by microbial agents are strongly dependent on the sensitivity report from each laboratory.…”

An In Vitro Study of Effect of Water Soluble Vitamin B Complex on Antimicrobial Activity of Antibiotics against Klebsiella species Isolated from Respiratory Samples

“…Vitamins play an important role in conferring immunity, which protects against infection (2,3) . Vitamin B complex includes Thiamine (B 1 ), Riboflavin (B 2 ), Niacin (B 3 ), Pyridoxine (B 6 ), Pantothenic acid (B 5 ), Biotin (B 7 ) and Cyanocobalamine (B 12 ).Various studies analysed the interactions of antimicrobial agents with other drugs, food products, vitamin K, vitamin C and vitamin E (3,4) .…”
