Is There Any Benefit in Taking A Multivitamin?

February 12, 2009

Go to fullsize imageI used to take one multivitamin pill per day.  I know of others who take tons of vitamins because they make them feel “better”. Or just a habit difficult to change. Or better still, relatives in the US send us with big bottles of these Vitamins as presents.  But are they USEFUL? 

Ever since, I already doubted the usefullness of these vitamins UNLESS one is not eating properly or is very choosy with food that predisposes one to deficiency of certain vitamins that we usually get from food.  But for people that have problems of the Opposite, that is… controlling the intake, I suggest you might as well spend your money on something else that’s healthy and has important benefit on ones health.

The latest issue of the Archives onf Internal Medicine published this recent study looking at the effectiveness of taking multivitamins.


Background  Millions of postmenopausal women use multivitamins, often believing that supplements prevent chronic diseases such as cancer and cardiovascular disease (CVD). Therefore, we decided to examine associations between multivitamin use and risk of cancer, CVD, and mortality in postmenopausal women.

Methods  The study included 161 808 participants from the Women’s Health Initiative clinical trials (N = 68 132 in 3 overlapping trials of hormone therapy, dietary modification, and calcium and vitamin D supplements) or an observational study (N = 93 676). Detailed data were collected on multivitamin use at baseline and follow-up time points. Study enrollment occurred between 1993 and 1998; the women were followed up for a median of 8.0 years in the clinical trials and 7.9 years in the observational study. Disease end points were collected through 2005.

We documented cancers of the breast (invasive), colon/rectum, endometrium, kidney, bladder, stomach, ovary, and lung; CVD (myocardial infarction, stroke, and venous thromboembolism); and total mortality.

Results  A total of 41.5% of the participants used multivitamins. After a median of 8.0 years of follow-up in the clinical trial cohort and 7.9 years in the observational study cohort, 9619 cases of breast, colorectal, endometrial, renal, bladder, stomach, lung, or ovarian cancer; 8751 CVD events; and 9865 deaths were reported. Multivariate-adjusted analyses revealed no association of multivitamin use with risk of cancer (hazard ratio [HR], 0.98, and 95% confidence interval [CI], 0.91-1.05 for breast cancer; HR, 0.99, and 95% CI, 0.88-1.11 for colorectal cancer; HR, 1.05, and 95% CI, 0.90-1.21 for endometrial cancer; HR, 1.0, and 95% CI, 0.88-1.13 for lung cancer; and HR, 1.07, and 95% CI, 0.88-1.29 for ovarian cancer); CVD (HR, 0.96, and 95% CI, 0.89-1.03 for myocardial infarction; HR, 0.99, and 95% CI, 0.91-1.07 for stroke; and HR, 1.05, and 95% CI, 0.85-1.29 for venous thromboembolism); or mortality (HR, 1.02, and 95% CI, 0.97-1.07).

Conclusion  After a median follow-up of 8.0 and 7.9 years in the clinical trial and observational study cohorts, respectively, the Women’s Health Initiative study provided convincing evidence that multivitamin use has little or no influence on the risk of common cancers, CVD, or total mortality in postmenopausal women.


In short … wanna live long?  Live a healthy lifestyle.  There are other ways to better living not simple taking of pills as a shortcut or better still … lets take a walk and think again.

Pills or exercise?  I know your answers…keep it to yourselves.  You choose … it’s your life!

    I think this is a good and timely advice Doctor. Given the spiralling cost of medicines in this economic downturn, this is one that can get off the list.
