Title:
Role of Antioxidants in Oxidative Stress Induced by High Intake of Alcohol
Abstract
Although there are genetic differences in the metabolism of alcohol, large amounts of alcohol intake can cause hangovers and, in severe cases, death due to acute alcohol poisoning. Once alcohol enters the body, it is metabolized mainly in the liver, where it is broken down into the highly hepatotoxic acetaldehyde. It is thought that excessive alcohol intake causes insufficient metabolism in the body, and the acetaldehyde induces oxidative stress, resulting in hangovers and organ damage. Therefore, we examined the effects of large amounts of alcohol on the body using SUPALIV, an antioxidant formula consisting of coenzyme Q10, vitamin C, vitamin B2, niacin, L-cystine, succinic acid, fumaric acid, and L-glutamine. Mice (C57BL/6, male, 6 weeks old) were intraperitoneally administered 5.6 g/kg of ethanol, and blood acetaldehyde and oxidative stress were measured. The results showed that acetaldehyde in the blood increased at 2 hours after ethanol administration and was hardly detectable at 24 hours. However, oxidative stress remained high even after 72 hours of ethanol administration, and antioxidant capacity was low. In contrast, SUPALIV-treated group suppressed blood acetaldehyde and the rising oxidative stress without reducing antioxidant capacity. In the mouse acute alcohol intoxication experiment in which 6.4 g/kg of ethanol was administered intraperitoneally, all mice in the Control group, to which nothing was administered, died after 12 hours. However, in the group that received SUPALIV (60 mg/kg) orally three times, 30 minutes before ethanol administration and every 12 hours after ethanol administration, the survival rate was 100%. These results suggest that heavy alcohol intake increases oxidative stress in the body, and that this oxidative stress may be a factor in acute poisoning deaths. In contrast, the antioxidant compound SUPALIV suppressed acute poisoning deaths by speeding up the metabolism of alcohol and suppressing elevated oxidative stress. In conclusion, heavy and prolonged alcohol intake causes significant oxidative stress in the body, which may lead to aging and disease. Therefore, countermeasures against oxidative stress caused by alcohol intake are important, and SUPALIV was shown to have the potential to reduce this risk.
