switching to centrum chewables

on 10/16/08 3:41 am
ok, im switching from flinstones to centrum chewables... i just got them this morning & when i was looking around would have much rather gotten the ones that I could swallow whole but wasnt sure if I would absorb them as well so I didnt... anyways, my question is how many a day do i take? My nut had me taking 2 a day of the flinstones but after hearing everything on here i figured it cant hurt to switch to an adult vitamin and if its a chewable it should absorb just fine, right? so i guess im a little confused as to why she wanted us to take the flinstones if we could get the same thing in adult vitamins. I didnt even know they had the chewables. since its not a kids vitamin, is one a day enough? Or is the requirement different for bariatric patients? thanks!

My surgeon just has me take one of the Centrum per day (but I double up and take two a day for a few days if I am feeling run down or preparing for or recovering from surgery (or illness).

I have no idea why some surgeons suggest Flintstones since those are made for the needs of children not adults (perhaps the surgeons just don't know about the chewable Centrum...?)

The American Society for Metabolic and Bariatric Surgeon's recommend a dose twice the normal adult dose, per day.

So in this case, 2 per day.

Have a great one.

I also take 2 centrums a day. Seems to work just fine so far.

I was taking Centrum Adult Chewables for a while, 1 a day. Now I just take one Centrum Performance Tablet every day (in addition to my iron, extra vitamin C, B-12 and calcium).

Amy , why is it you take Iron ?                       Isn`t Iron in the Centrum vit?

on 10/16/08 12:41 pm - Danvers, MA
My labs have indicated that I am anemic, so I take iron because I'm anemic. There's apparently not enough iron in the Centrum to deal with my anemia, and/or the calcium that is also present in the Centrum is minimizing the iron absorption.

My Nutritionist at Barix (Mary) told me that it was okay to take the "Flinstone's Complete Chewable Multi-Vitamin" (2 per day), but she did also say that I could take "Centrum Complete Chewable Multi-Vitamin" too (1 per day).  I think it's a matter of choice due to taste.  I prefer the children's, because I find the adult chewables disgusting.

My surgeon and bariatric coordinator suggested 2 childrens chewables a day, not Flintstones, because they have more iron.  I take 2 Active Kids daily.

Before surgery, I asked my nut and doctor repeatedly if I should take 2 of the Centrum chewables and they said 1 is fine (because I see a lot of people on this forum that take 2 mv's).   My doc said only 20% of my intestines were bypassed and I don't have THAT much malabsorption to have to take 2 mv's and 1 would do (vs someone who had the DS and had much more bypassed than a RNY'er).   And personally, I hated the taste of the Centrum chewables (and still do but have gotten used to it)!!  I take a chewable 500mg Vitamin C right after it (tastes like OJ) to help with the iron absorption and also for my immune health.   Helps take that nasty taste out of my mouth too.   I've talked to other patients 1+ out that are taking 1 centrum a day and their labs are fine. 

There's also Centrum Silver chewables you can take (which I've heard tastes a lot better), but it doesn't have iron it and you'd have to take a separate iron supplement.

Hit goal weight of 140 at 13 months out from RNY!! 130 pounds GONE!

I take the centrum silver chewables "orange" flavor, they are pretty good, I also take a separate iron chewable from Bariatric Advantage "passion fruit" flavor.  I'm not quite 4 months out and havn't had any labs yet, so I don't know where my levels are. 

Lost 20lbs before surgery...

Well, I don't know what's "best", but I've been taking 2 Centrum Chewable vitamins a day for the past 11 months!   (Of course, that's along with all my other vits and minerals: calcium, iron, vit D and B12).

I use the Centrum Chewables.  TWO per day. 

We do not have a normal digestive system any longer so we must take double the RDA after gastric bypass.  Not only are we malabsorbing the supplements we take to some extent, we're also malaborbing the nutrients we'd normally get from food if we had a regular digestive tract.

I take centrum Chewables. I'm another victim of the nuts saying that a childrens vitamin is enough. Flintstones are meant for tiny bodies that are in good health. Do as much research as you can on this, and be an advocate because we can't always rely on the "professionals".

AMAZING how many people are still taking children's vitamins (flinstones in particular) given all the facts that have been posted on here about them in the last 2 weeks.

Since I'm almost out of NatureMade Liquid Gell multis, I just bought chewable centrum as well.  As others have said, the suggested dose for RNY patients is double the regular suggested adult dose.  I, personally, apply this to EVERY suppliment I'm taking now. 

BTW, centrum only has 18g Iron per pill.  So if you take 2 that's 32g.  The absolute lowest dose I have ever seen suggested for menstrating women is 30g daily.  Most of those who are serious about their vitamin intake are taking more.  I'm taking a total 77g of iron daily.

I know alot of people talk aout flinstones but my kids take them if you look at the back of them they have  the same as the chewable centrum,I take the centrum . I am just curious if any one looked at  the flinstones or is it word of mouth people judge  them?Truth is the flinstones say 1/2 for younger children and 1 for adults. Not trying to be mean but  I see a lot of people get rude about  the  flinstones  but have no clue what they are talking about ?
on 10/16/08 3:49 pm - Medford, MA
You're exactly correct.

There really isn't very much difference between a chewable Flinstones' multivitamin and a Centrum Chewables multivitamin.  Just a few micronutrients like molybdenum and manganese, maybe chromium, none of which even have well-defined deficiency states.  Someone tell me please when a post-op RNYer staggered into her doctor's office only to be immediately hospitalized for having a chromium deficiency!

Multivitamins are also chockful of what I'd call "crapware": potassium, phosphorus, calcium, magnesium, chloride, boron, nickle and silica, just to name a few items that are useless components of a multivitamin supplement, either because they're macronutrients which a multivitamin can't contain enough of OR because they are macronutrients which are virtually impossible to be deficient in OR they're junk which has no known role in human nutrition.  But they make the list of ingredients longer and more impressive-sounding.

Centrum has more of EVERY nutrient except Vitamin C. In some cases double.  So it would take 2 Flinstones to equal 1 Centrum.  The suggested dose for post RNY patients is 2 Centrum.  To even come close, you'd have to take 4 Flinstones.  Even then there are things in Centrum that are not in Flinstones.  I haven't researched the importance of each and every one of them.  All that I've seen is that it doesn't have things like Zinc and Magnesium.  I know that a Magnesium deficiency has been linked to things like migraines, fibromaylgia, allergies, and asthma.

It's up to the individual what they choose to take.  I just do not understand why they would choose to take it.  Of course I don't pick my vitamins based on taste, but instead on my nutritional needs.

If you felt like I was being rude then I completely apologise because that was not my intention.  I just do not get why anyone would take Flinstones.  That's my opinion.  I am not a medical professional and do not claim to be.  I simply read labels and am still trying to make sure my own vitamins are where they should be.

Look at your jar of flintstones and the centrum compare the two , if you look they are the same  and the dose says one for adult . I am not sure why so many people  judge them ? Truth is they taste better ? My kids take them I am asking my nut  if i can .
