Why big studies say supplements don't work
People who use supplements have a less healthy lifestyle. Taking a supplement makes people feel invulnerable, and as a result they eat less healthily and exercise less. Psychologists at the Southern Taiwan University discovered why, in large-scale epidemiological studies, supplements often have little or no positive health effects.
Many supplements show interesting effects in laboratory studies, but in big studies they don't seem to make their users healthier. Ginkgo biloba is a good example: it strengthens bones, boosts sex drive, deactivates estradiol [J Steroid Biochem Mol Biol. 2006 Aug;100(4-5):167-76.],
extends lifespan, delays muscle aging and inhibits cortisol. And there are many smaller studies in which ginkgo has been shown to delay mental aging and to protect against dementia.
Nevertheless, when epidemiologists monitor large groups of people for an extended period, they often can't show convincingly that ginkgo reduces the likelihood of dementia. [Cochrane Database Syst Rev. 2009 Jan 21;(1): CD003120.] A recent review concluded that ginkgo is safe and does have a positive effect; but that the effect is so modest that it's not clear whether it really helps. [BMC Geriatr. 2010 Mar 17; 10:14.]
The Taiwanese turned to psychology in their search for an explanation of the absence of clear positive epidemiological effects of supplements, and performed two psychological experiments.
The first experiment involved 82 subjects, aged between 18 and 46. They all had to take a pill. Some subjects were told that they were getting a multi-vitamin preparation, and the others were told that they were getting a fake pill with no active ingredients.
Afterwards the researchers asked the subjects how vulnerable or invulnerable they felt. They discovered that the subjects who thought they had been given vitamins and minerals were more likely to believe that they wouldn't easily fall ill. According to the researchers, supplements give people ‘illusory invulnerability'.
When the researchers let their subjects choose between a healthy meal of organic products or a buffet with obviously calorie-rich food full of sugar and trans fats, the subjects who thought they'd taken vitamins chose the unhealthy buffet more often.
For their second experiment, the Taiwanese used 68 students, who were also given a pill. Some were told that it contained nothing and the others were told that it contained vitamins and minerals. After taking the pill the subjects had to walk, but were allowed to decide for themselves how far they went and for how long. The researchers observed that the subjects that thought they'd taken vitamins and minerals walked less far.
The table below summarizes the findings.
"People who rely on dietary supplements for health protection may pay a hidden price: the curse of licensed self-indulgence", the Taiwanese conclude. "Policy interventions that remind individuals to monitor the licensing effect may help translate the increased use of dietary supplements into improved public health."

I don't think I buy that. How do we know the people in the study are representative of people who actually take supplements of their own accord? The study supposedly looks at the psychology of those who take supplements but the participants in the study aren't necessarily supplement takers in the real world. I think people who take supplements are more concerned about their health than those who don't. I can't imagine some fat country boy who eats fried chicken and beer every night is likely to give two shits about taking any supplements.
I think there are those, in the real world, that eat unhealthy diets and sit on the couch all day then take a cheap no name brand of multivitamin believing it to be a silver bullet that got them covered. People must be willing to educate themselves... sorry for the soapbox response.

One study vs. almost everybody on this board seeing results from supplements...hmmmm.....
people on the board are pushing themselves toward better health and or a better body aka they are motivated.

It's the "Diet Soda Syndrome". You know, the people who order the bucket of KFC for themselves with a diet Coke. People *want* to indulge themselves, and to many, a supplement is simply something that allows more leeway to indulge. In larger study populations, especially uncontrolled ones, this has a 'damping' effect on the data which definitely tends to hide beneficial results. People trend toward 'normal', neither over or under healthy.
"I ate healthy so I don't have to walk as far to be back to average."
vs
"I ate unhealthy so I have to walk farther to be back to average."

I'll disagree with you there. I walk into my bodybuilder supplement shop and I see a wall of whey, another wall of gainers, and one wall that's half creatine, glutamine, and whatever's the rage at the time (N.O. boosters currently), which leaves half a wall for vitamins, coq-10, zma, hmb, omegas, etc.
But, if you walk into a drugstore like CVS or Walgreens, there's a whole aisle, both sides, dedicated to those same things that get only half a wall in a place like GNC. I think the general public is more interested in taking something that is supposed to improve health than actually improving their health. I mean, the vitamin section was larger than the painkiller section in the CVS I was in 2 weeks ago, and the Coq-10 was cheaper at CVS than the Vitamin Shoppe I checked out in NYC.
We tend to think that a lot of these supps are directed toward fitness geeks, but I think Joe Average is probably by far a larger consumer, and Joe Average takes his supps and believes he has more room to indulge, and so he does. It's the Joe Average types that are the noise drowning out the response signal from people who truly do care about their health *and* understand diet and nutrition.



TRue^

as i said in another thread and pissed people off....supplements are truly overrated..all research done on them is for commercial purposes...the supplements are not going to do the job for you and if you think they are helping it is because it is all in your head and you are probably working out harder ...supplements are only helping you in psyching yourselves up ..well you can do that without supplements, you can get a partner and motivate each other it works better. and another thing is that nobody talks about long term effects ( years) of using supplements because such a study is very hard to do it takes years.
i am 50 years old and back when i was 26 or so i worked out with a guy who does compete and we worked out really good until he started his steroid cycles and started to work harder...i did not take any roids but i stepped up my workout just to keep up with him.and guess what? i almost ( i say almost) got the same gains that he did ..i rest my case.
as a rule of thumb eat properly and use the minimum amount of supplements if you really need it, that is your body can tell you what you need..listen to your body


i dont buy that crap. just because u take a multi doesnt make me feel invulnerable. thats bogus
