Possible Interaction: Antioxidants and Vitamin A

“Since in … of vitamin A … antioxidant effects that are more potent than those of vitamin E (treatment with which has been ineffective in these diseases), the purpose of … determine whether administration of supplemental vitamin A to premature infants deficient in this vitamin would have an antioxidant effect in vivo.”

“Thus, vitamin A seems to be protected in vivo by other antioxidants and proteins rather than protecting other molecules.”

“In this study, antioxidants on paper combined with vacuum treatment were found to greatly increase the stability of DBS retinol during 120 min of air drying and 30 days of room-temperature storage.”

“Studies have also ascribed a role to vitamin A in up-regulating the antioxidant enzyme functions in the body.”

“Finally, a meta-… administration of antioxidants was associated with an increase in … (95% CI 1.02– –1.11), vitamin A — RR 1.16 (95% CI 1.1–1.24), vitamin E — RR 1.04 (95% … defined adverse effects and no clear benefits with vitamin C or selenium supplements [5].”

“BackgroundOxidative stress plays a role in nonalcoholic fatty liver disease (NAFLD) pathogenesis and may increase consumption of vitamin A for antioxidant purposes.”

“ Retinol at 10 and 20 μM increased free radical production, oxidative damage and antioxidant enzyme activity in A549 cells.”

“We investigated associations of dietary intakes of retinol and antioxidant vitamins with colorectal cancer risk in 816 incident cases of histologically confirmed colorectal cancer and 815 controls randomly selected for the Fukuoka colorectal cancer study in Japan.”

“ Vitamin A concentrations are lower in BPD infants which may result in a reduction of the antioxidant protection.”

“Therefore, it is very important to add antioxidants during Vitamin A production.”
