Vitamins Reduce the Benefits of Your Workout

Free radicals create oxidative stress on a cellular level and have long been considered a major culprit of the aging process. Since antioxidants clean up those free roaming bits of "reactive oxygen compounds," one would think vitamins loaded with free radicals would help folks live longer. However, last Spring, researchers found that taking high doses of vitamins may decrease life span rather than lengthen it.

Now a new study has found that taking moderate doses of vitamins E and C interferes with the benefits of exercise, specifically the increase of metabolism and diabetes prevention through insulin sensitivity.

It seems the antioxidants found in vitamins C and E are too efficient at mopping up free radicals, and our muscles need a little bit of cellular damage caused by oxidative stress to jump-start their natural defense systems. Researchers wholeheartedly believe more research should be done in this area, and that we should not worry about getting too much of these vitamins in our diet naturally; it is supplements that should possibly be avoided.

This is so confusing. I only take vitamins for calcium because I'm vegetarian and sometimes vegan, but now I'm worried.

Actually KatieDyl, some vitamins actually ARE toxic in very high doses, so you have to be very careful with those mega-supplement doses. I try to get most of my antioxidants from food sources and then I pop a multi to sort of cover any missed things. But this study makes me wonder about things like that resveratrol pill that concentrates 20 bottles' worth of wine into a sounds good, but in reality, it's not a good idea.

oh my goodness! these scientists and their studies should get together and make up their minds. should we be taking vitamins or not? as much as i try to eat healthy i know i don't get 100% of what i need from my diet, and with a new study coming out every week i'm confused and i have a headache...maybe it's my vitamins

I completely believe this. It seems like this country is vitamin obsessed (probably from guilt of bad eating). A lot of vitamins are water soluable so you're literally peeing your money away! One good multi is all anyone needs.

I know, tls! That's why lately I feel like we should just look at cultures that have people who live to be 100+ and adopt their habits. :D

Another example of a "wow, so I've been doing it wrong this whole time...maybe?" study. These things are confusing.
