According to research, vitamin C and E – given separately – improve insulin sensitivity, i.e. the body´s ability to respond to the action of the hormone insulin in decreasing blood sugars. This is due to their inhibitory effect on inflammation, which is a key factor in insulin sensitivity. Based on these findings, the present study investigated the combined effect of vitamin C and E on insulin activity. 13 elderly men with increased blood sugars levels (a common feature of insulin resistance) were administered vitamin E (1000 mg/day) and vitamin C (1000 UI/day) for 4 weeks. The results showed that the combined administration of vitamin C and E lowered inflammation and improved insulin action. More details can be found in the study.
