Taking high doses of vitamin C and E

They studied a group of wild voles and found those given high doses of vitamins C and E had their lifespan reduced by a quarter.
 
Antioxidants, such as vitamin C and E, nu skin product are often marketed as anti-ageing supplements that work by slowing down cellular ageing.
 
"When we began our research we expected voles' lifespans would be boosted by the vitamin supplements in a similar way to the mice we had tested previously so we were surprised to see that was not the case nuskin," Professor Colin Selman from Glasgow University said.
 
"Our findings suggest major differences exist in the effects of high doses of antioxidants on oxidative damage and lifespan across species."
 
Louis Roller, an honorary associate professor at Monash University, nuskin group told MSN humans don't need vitamin supplements unless they have received medical advice that they have a deficiency.
 
"Most deficiencies are rare in this country because we have a generally good diet," Associate Professor Roller said.
 
"Vitamins do not give energy or stamina or increase your focus, like some ads say. One orange is the equivalent of all you need of vitamin C in one day."
 
Women need just 4mg a day and women need 3mg of vitamin E each day, but tablets containing up to a hundred times this amount are available in health food shops.
 
Associate Professor Roller said it makes sense why scientists used to think that high doses of vitamins would undo oxidative stress that speeds up ageing nu skin hk, however studies have shown they don't work and if anything can reduce life spans.
 
"It's a multi-billion dollar industry and they spend a lot of money on false advertising," he said.
