the medical community has been warning us against using supplements for years.
Vitamins and Supplements May Lead to Earlier Death
People taking vitamins or supplements are more likely to die over a given period than people not taking them, a new study from Finland says, adding weight to recent findings from the U.S. along those lines.
In the new study, researchers gathered data on nearly 1,800 people between the ages of 62 and 74 who were participating in a prospective, population health study of the residents of one town in Finland.
Over a 10-year period, 59 of the 221 people (26.6 percent) taking a vitamin or supplement died, whereas 281 of the 1,553 people (18.1 percent) of the nonusers died.
After the researchers took into account other factors that can affect a person's risk of dying — such as age, gender and smoking — they found that people taking vitamins or supplements were 50 to 70 percent more likely to die over the course of the study than those not taking them, said study researcher Dr. Tomi-Pekka Tuomainen, of the University of Eastern Finland.
The findings are in line with a recent study from University of Minnesota researchers, who looked at 38,000 women who were around age 62 at the study's start, and found a slight increase in mortality among those taking vitamins or supplements. They found, for example, that 40.8 percent of 13,000 women taking a daily multivitamin died over the 19-year study, whereas 39.8 percent of the 10,000 women who hadn't taken a daily multivitamin had died.
Both studies showed an association, not a cause-and-effect link.
The Minnesota study had prompted ideas that supplement users were a "self -selected" group, Tuomainen told MyHealthNewsDaily. It could be that people who take supplements tend to have more health problems than nonusers to start with, or are more likely than nonusers to have close relatives with health problems (which could mean they are at greater risk for developing later problems themselves).
But the new study suggests that those hypotheses may not explain the increased death risk, Tuomainen said. He and his co-authors adjusted their analysis to account for people who reported pre-existing diseases and a family history of the "major killer" diseases, he said.
The adjustment brought down the increased risk of dying seen among the supplement users, but did not make it disappear, he said.
Part of the reason behind the link may be that taking vitamins or supplements that include more iron or copper than the body needs are harmful for health, Tuomainen said. These metals are pro-oxidants, and may trigger the type of stress in the body (oxidative stress) that is associated with chronic diseases, though more work is needed to show this.
The findings are published today (March 12) in the journal Archives of Internal Medicine.

My opinion is that most supplements are worthless, not all, but most. The literature strongly supports the idea that they're worthless, and quite a bit of new research is suggesting that some, particularly the megadosed ones may actually be harmful.
You just can't isolate single nutrients and put them in pill firm at 1000% of how much you should get and think that you're going to get the same results as eating a well balanced diet full of whole grains, legumes and tons of fruit and veges.
Complete crap. That study is flawed..2% over 13000 people over 19 years? Please.

Although dietary supplements are commonly taken to prevent chronic disease, the long-term health consequences of many compounds are unknown.
We assessed the use of vitamin and mineral supplements in relation to total mortality in 38,772 older women in the Iowa Women's Health Study; mean age was 61.6 years at baseline in 1986. Supplement use was self-reported in 1986, 1997, and 2004. Through December 31, 2008, a total of 15,594 deaths (40.2%) were identified through the State Health Registry of Iowa and the National Death Index.
In multivariable adjusted proportional hazards regression models, the use of multivitamins (hazard ratio, 1.06; 95% CI, 1.02-1.10; absolute risk increase, 2.4%), vitamin B(6) (1.10; 1.01-1.21; 4.1%), folic acid (1.15; 1.00-1.32; 5.9%), iron (1.10; 1.03-1.17; 3.9%), magnesium (1.08; 1.01-1.15; 3.6%), zinc (1.08; 1.01-1.15; 3.0%), and copper (1.45; 1.20-1.75; 18.0%) were associated with increased risk of total mortality when compared with corresponding nonuse. Use of calcium was inversely related (hazard ratio, 0.91; 95% confidence interval, 0.88-0.94; absolute risk reduction, 3.8%). Findings for iron and calcium were replicated in separate, shorter-term analyses (10-year, 6-year, and 4-year follow-up), each with approximately 15% of the original participants having died, starting in 1986, 1997, and 2004.
In older women, several commonly used dietary vitamin and mineral supplements may be associated with increased total mortality risk; this association is strongest with supplemental iron. In contrast to the findings of many studies, calcium is associated with decreased risk.
Multivitamin use and risk of prostate cancer in the National Institutes of Health-AARP Diet and Health Study.

Multivitamin supplements are used by millions of Americans because of their potential health benefits, but the relationship between multivitamin use and prostate cancer is unclear.
We prospectively investigated the association between multivitamin use and risk of prostate cancer (localized, advanced, and fatal) in 295,344 men enrolled in the National Institutes of Health (NIH)-AARP Diet and Health Study who were cancer free at enrollment in 1995 and 1996. During 5 years of follow-up, 10,241 participants were diagnosed with incident prostate cancer, including 8765 localized and 1476 advanced cancers. In a separate mortality analysis with 6 years of follow-up, 179 cases of fatal prostate cancer were ascertained. Multivitamin use was assessed at baseline as part of a self-administered, mailed food-frequency questionnaire. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated by use of Cox proportional hazards regression, adjusted for established or suspected prostate cancer risk factors.
No association was observed between multivitamin use and risk of localized prostate cancer. However, we found an increased risk of advanced and fatal prostate cancers (RR = 1.32, 95% CI = 1.04 to 1.67 and RR = 1.98, 95% CI = 1.07 to 3.66, respectively) among men reporting excessive use of multivitamins (more than seven times per week) when compared with never users. The incidence rates per 100,000 person-years for advanced and fatal prostate cancers for those who took a multivitamin more than seven times per week were 143.8 and 18.9, respectively, compared with 113.4 and 11.4 in never users. The positive associations with excessive multivitamin use were strongest in men with a family history of prostate cancer or who took individual micronutrient supplements, including selenium, beta-carotene, or zinc.
These results suggest that regular multivitamin use is not associated with the risk of early or localized prostate cancer. The possibility that men taking high levels of multivitamins along with other supplements have increased risk of advanced and fatal prostate cancers is of concern and merits further evaluation.
These studies always crack me up. I get your point, taking supplements doesn't make up for other life choices, like exercise and diet, but taking a study with such a small number of people and make assumptions and not correcting for the externalities does allow for any solid conclusions.
For the record, I agree most of the supplements are worthless, and some actually do harm people. For example, the article you referenced about prostate cancer; research is linking chemical vitamin E to increased incidences of prostate cancer. From what I understand, the chemical version of the vitamin actually displaces the vitamin obtained from food sources and causes damage to the prostate. So, I don't take that.
But, just because someone makes a blanket statement that supplements are bad for you, doesn't mean I'm going to stop taking vit d, fish oil, or my organic green source multi. That would just be alarmist, and stupid.
Horse crap...... The difference in death rate between the women who took them and didn`t is too small to attribute any conclusion. Old people die..... that's what they do.
I supplement my sex life with porn! Does this mean i should be buying funeral insurance?
"The Minnesota study had prompted ideas that supplement users were a "self -selected" group, Tuomainen told MyHealthNewsDaily.

This along with mega doses of certain vitamins or minerals might carry more weight than is suggested in this article. I'd like to see a similar study of only high risk individuals, seperated by critical illness.
I take half the recommended dose of opti-men, just as insurance (among other things). I also believe you can get most of your nutrients through food, though overfarming has reduced the nutrient content of a lot of foods...

I'm not suggesting that folks come to a conclusion based off of this one study, but there is a trend recently where the research is suggesting that not only are most supps worthless, but the megadosed ones can actually be counterproductive.
Btw, I take fish oil and ironmag cycle support. So, I'm not anti supp, just trying to be the best consumer I can.
I also take fish oil, acetyl l-carnitine and milk thistle.
Will be starting NAC after I read this study...it's already on the way...

Yeah, this study is just a very small piece of the puzzle.
I always avoid iron in my sups. My multi is iron free.

First of all..... you are accepting data generated by the Elite Medical Cartels, a group that stands by their assertion that mustard gas and radiation is the best cure for all cancer...all of which have a vested interest in maintaining poor health in humans.
Second.... studies cited are of adults in the later part of their lives not taking into consideration just what damage they had done to their bodies earlier in their lives.
Third... its not the supplements that are the culprits here, but most of our common food chain, which is the true poison, or close to it.
Forth... Multi-Vitamins have no real nutritional value, due to the nature for which they are produced and the ability of the body to absorb them.
Fifth... where as it is true that there are the good and the bad in the supplement arena, most supplements used in the right ways have benefits just about every person on the planet can benefit from. Why do you think they want to ban or severely control supplements!
When I was lifting I lived on supplements and did away with the crap we call food.... supplements are basically concentrations of nutrients found in our food.
I work in the medical field and if it wasn't for clinical trials, medications, surgeries etc, we'd see a lifespan in the 50's for americans. Western medicine, with all of it's problems is far superior to any other form of medicine and the numbers back it up.
I agree with some of what you said, i just don't share your conspiracy theory attitude towards medicine. are there problems? of course, but I don't place any more trust in supplement companies that stand to get rich off of their products than I do for the pharmaceutical comps.
I just watched the trailer for the movie "forks over Knives" and where as it had some interesting info in it, it hints at a very un healthy concept as well. Vegetarianism. We humans are not animals nor were we designed to eat plants only. We are meat eaters, plain and simple.
The lack of meat in our diets can cause major problems with human health. It did mine. I did vegan for 3 years because I was living with a vegan woman who cooked only vegan. I lost so much muscle mass it was pathetic. I believe its harder on men then women but it is detrimental to both genders.
A vegan diet can be very unhealthy though, especially in those that aren't really strict about what they eat. But, the literature is very clear that vegetarians have the best bio profiles. The lowest BP, cholesterol, triglycerides, cardiovascular disease and the lowest rates of obesity and diabetes. I actually did my masters thesis on vegetarianism and heart disease. I literally have 20 studies showing the positive effect on cardiovascular health. I can share them if you want.
what happens is that people stop eating meat, but don't put together a good vege diet. for instance, i could live off of french fries and soda and be vegetarian but very unhealthy. Nobody is going to argue that someone who eats tons of legumes, whole grains, and fruits and veges is going to be unhealthy.
And, there are many cultures that eat very little meat and are the healthiest out there. Japan is a great example.
Am I a vegetarian? no, I love meat and cheese too much. But, I rarely eat red meat, pork, processed meats, dairy, and a moderate amount of eggs and cheese.
I'm also not trying to argue that people should be vegetarian by any means, I think there are many ways to eat and be healthy. I think that meat and cheese can definitely be part of a healthy lifestyle, but in moderation, particularly processed meats.
Now from an economical standpoint vegetarianism is much more efficient. In the amount of land it takes to raise enough beef to feed one person for a year, that same amount of land can grow enough vegetables to feed 20 people.

Acording to the AMA in JAMA 80% of the advancements in medicine and better health has been due to the creation of adequate sewer systems. Medicine had nothing to do with that. Its a big fraud. If you would like to get into this I have a good data base of facts to back up my statement.
In America alone, over a million are killed in hospitals each year,or by going to doctors....
And don't even get me started on big pharma..... witch doctors have become their corner drugs dealers
As I said...its a scam... and a very lethal scam at that!!!
Blood pressure meds are a great example of the benefits of western medicine and medications. A ton of my patients would be in worse shape if it weren't for their Bp meds, or theyd be dead. Blood thinners are another great example. Cardiac bypass and stents are great examples of the surgeries that are keeping folks alive. Hip replacements are great examples of a surgery that gives patients their life back. Are you suggesting these guys just take supps for their health problems?
