Family Nutrition: What’s the deal with Multivitamins?

This is definitely one of my top ten questions from clients and frankly it’s a hard question because there isn’t a generic answer.  The internet and such stores as the Vitamin Shoppe and GNC continue to place a lot of focus on vitamins and minerals and some of my clients swear by their regimen.  I’ve even had some clients tell me they can tell a difference within hours of taking certain supplementations.   Since this is a subject I try to tame my responses too, I was very glad to see the article “Multivitamins, So Many Types, So Many Labels” by Melinda Beck in the Wall Street Journal published June 21, 2001. 

Did you know that the multivitamin is the number one dietary supplement producing $4.8 billion back in 2008 and that one third of American’s take multivitamins religiously?  As Melinda points out there are many different varieties of multivitamins yet there is no specific formulation that specifies what a multivitamin should look like.  This becomes confusing especially when looking at wide ranges of ages and co-morbidities.  A multivitamin can be a mixture of any vitamins and minerals and the only specification is that it has to list ingredients on the label.  What’s more, 10 of 38 multivitamins tested by ConsumerLab showed that ingredient listings didn’t jive with actual amounts in the bottle.   Price was also not a factor as some of the multivitamins that sell for ten cents a day performed better than vitamins that sell for fifty cents a day.

There have been many studies on the use of multivitamins.  Some cited in this column show associated benefits, some show insufficient evidence that multivitamins decrease death from cancer or cardiovascular disease. 

At the end of the day, there are definite populations that require an increased vitamin or mineral consumption.  Pregnant woman, infants, elderly, or specific chronic conditions require an increase in specific vitamins and minerals and if you are not able to get the recommended amount from food, this is when supplementation should occur.  As far as a generic multivitamin I’m not completely sold it is a necessity.  I  agree it should be recommended when an individual has poor eating habits or does not eat enough whole fresh foods, but for the most part if you are eating well rounded meals, my request will be to review labs and make individual recommendations from there. 

I’ll close with a comment from Dr. Coates, of the NIH, who says based on the best evidence, "If you are taking multivitamins, there is no reason to stop, and if you are not taking them, there is no reason to start. You are unlikely to harm yourself, whatever you're doing." Pretty compelling isn’t it? 



Always choose whole foods first as a source of vitamins and minerals

I take supplements for Vitamin D, B12, and folate which I am deficient in. I really try to focus on eating a lot of fresh vitamins and minerals to obtain the rest of the minerals and vitamins I need,

Miraculous Misconceptions: Raspberry Ketones

The interwebs are abuzz about the supposedly “miraculous” Raspberry Ketone supplements. Raspberry Ketone popularity started with Dr. Oz's show in February 2012, when he nicknamed it a “miracle weight loss drug.” Some even credit Raspberry Ketones with stimulating hair growth, but for our purposes here, let’s talk about weight loss. Raspberry Ketones are derived from red raspberries. Proponents claim that the supplement will stimulate your metabolism causing weight loss. However, there are no reliable studies to prove this.   Specifically there is no scientific evidence to show how it alters metabolism to promote weight loss. There is also no scientific evidence to determine a proper dosage. If you find a study that claims otherwise, check the funding source. Most likely, that study was funded by a company who produces or funds raspberry ketone products. As far as I know, no major pharmaceutical companies are investing in Raspberry Ketone research. And it is my opinion ...

Body Image

Becca and I recently started a BRAVE  Ed Group for our Eating Disorder Patients. The goal is to provide education about the Eating Disorder recovery process in a group format to decrease feelings of isolation and offer an opportunity for all to share positive affirmations, approaches etc. Last week we talked about Body Image. We completed an activity in The Body Image Workbook for Teens by Julia V Taylor PhD which was very insightful. In this activity all the different body parts were labelled and you were supposed to jot down your first thought. Once completed you then determined if the initial thought was a judgement or truth statement. This sounds a lot easier than it really is. In the last week I've really been thinking about this.  Negative body image is often the first symptom that precipitates the action to make a change to your body. If the action, reducing calories or over exercising for example, becomes compulsive and irrational this exacerbates the negative bo...
