No criticism
have there been no criticisms of multivitamins i also agree with the preceding statement
- I heard that vitamin supplements are not very efficient, according to a med student here in Norway... can anyone come with a statement to the efficiency of most over the counter multivitamins, preferably comparing them to other vitamin supplements. cKaL 18:14, 23 March 2007 (UTC)
'time release' niacin?
what is mean by "time release niacin, especially old versions over one hour" ? —The preceding unsigned comment was added by Substantiate (talk • contribs) 02:55, 20 March 2007 (UTC).
- Niacin is typically marketed in several forms, from pure, "instant release" niacin () to various degrees of time release. also see this discussion The old slow("sustained") time release tablets, over 1 hour, are the type most frequently associated with problems, especially with alcoholics and advanced liver disease. New, "extended" or "intermediate release" forms (e.g. Enduracin and Niaspan), under one hour have been offered in the US to optimize the flushing and slow release side effects to improve compliance for HDL and dyslipidemia improvements.--TheNautilus 04:34, 2 April 2007 (UTC)
Needs studies
This page should link to large, long-term, randomized, placebo-controlled, double-blind studies of the effect of specific commercially available multivitamin supplements on objective measures of intelligence, strength, endurance, disease, scholastic achievement, etc.
Multivitamin (with iron) use & prostate cancer
The current article looks like someone has naively swallowed all the advertising hype. These articles http://news.bbc.co.uk/1/hi/health/6657795.stm http://jnci.oxfordjournals.org/cgi/reprint/99/10/754 http://jnci.oxfordjournals.org/cgi/reprint/99/10/742 , on the other hand, show that using multivitamins increases the risk of death from cancer, because there is a narrow margin between a good dose or a harmful dose of vitamins. I used to think I was doing myself good from taking a multivitamin, but after carefully studying the second article I now no longer take any vitamin pills but just eat a varied diet. 80.2.221.47 20:16, 1 August 2007 (UTC)
- Just to clarify.. the second article actually concludes that "These results suggest that regular multivitamin use is not associated with the risk of early or localized prostate cancer." It says that overuse (more than 7 times a week) can lead to higher risk of fatal prostate cancer. But many people use multiple supplements together, which could lead to a total of more than 7 supplements a week.

- I have previously discussed this some. This test was largely conducted with the 80s-90s era formulas before Centrum Silver became a commonplace "mainstream" iron-free mulitvitamin/multimineral supplement with other mainstream brands following over the last dozen (or fewer) years. Typical daily multivitamin formulas then had 16-30 mg iron, commonly 18 mg Fe, for a single daily dosage. The "More than seven times a week" category might be loosely interpreted as usually twice a day. As I showed previously, any (excess) iron was already considered a big no-no in prostate cancer. One tab with iron might be one too many for certain people. If you go to your drugstore and look at the current "50+ seniors'" and "male" multivitamin versions, they typically leave out the iron (0 mg) or cut it to about 4-9 mg Fe if they put any iron in at all. The "(fertile) female" formulas will typically still have 16-18 mg.--TheNautilus 11:05, 16 November 2007 (UTC)
- I am moving the NCI study edit here as redundant (A&E) & narrow with undue weight on multivitamin formula issues that are also already dated, e.g. the Theragran-M formula listed in the study used 27 mg iron per tablet(!), implying 54 mg iron per day or more for prostate cancer victims(!!!), before Thergaran-M formula's market shift ~2002 to 18 mg with the "Advanced formula".--TheNautilus (talk) 10:21, 5 March 2008 (UTC)
