One of the most important commitments you can make to yourself when you undergo bariatric surgery is a lifelong commitment to taking recommended vitamin and mineral supplements. Unfortunately, you will be unable to rely on meeting your nutritional needs through diet alone once you have surgery – regardless of which procedure you choose.
Quality of Supplements
Ingredients in dietary supplements come from all over the world; many from China, India, and third-world countries where controls on processing may be inferior to those in the U.S. or Europe. Manufacturers may choose from a variety of sources, forms and grades of nutrients. Accepted standards for most nutrients follow the guidelines set out by the Unites States Pharmacopoeia (USP) and National Formulary (NF) and exist for more than 2,000 ingredients. If distributors choose to specify that they are using certified ingredients, these designators may appear on labels or may be omitted due to space limitations. If information is not supplied on the label, it becomes the responsibility of the consumer to obtain it.
Form and Delivery Method
The form and delivery method of these nutrients also make a difference in bioavailability and even toxicity levels. Without education on which form of vitamin or mineral you need, there can be vital differences in their functions; niacin, vitamin E, calcium, iron, selenium, and thiamine are just a few examples that can be found in a multivitamin that may not exist in the preferred form. Therefore, reading the daily value cannot be taken at face value as you may not absorb close to what the label claims you receive from the product.
Regardless of the delivery method – chewable tablets, liquids, hard-coated tablets, or gelatin capsules – the quality of nutrients and other ingredients are significant.
- Hard-coated tablets pose the greatest challenge to bariatric surgery patients as they typically break apart with stomach acid and churning. Some capsules are acceptable as they break apart with moisture and heat.
- Chewable products that are broken apart by chewing and liquids can also be ideal choices if the ingredients are appropriate and they are not sweetened with excessive amounts of sugar.
Unfortunately, one cannot rely on simply taking a multivitamin to achieve the desired results in preventing micronutrient deficiencies after bariatric surgery. While the majority of vitamin and mineral requirements can be met with the right multivitamins, you will need to focus additionally on calcium, vitamin B12, vitamin D, and potentially iron in addition to that in the multi formula (primarily for menstruating women).
to prevent bone resorption after surgery. If one is not supplementing a bariatric multivitamin formula containing at least 1000 IU vitamin D3, a maintenance dose should be taken and vitamin D-25-OH levels monitored routinely to ensure levels are not exceeding the normal limits.
More than likely, one who has bariatric surgery will face abnormalities in the area of micronutrients at some point following surgery. Therefore, it is crucial that treatment be aggressive to correct deficiencies along with lifelong screening to prevent bone loss, irreversible damage, and preventable complications.
Common Questions Post-Surgery:
- Are some vitamins better than no vitamins? Yes, of course.
- Are bariatric formulated vitamins worth the money? Yes, vitamin deficiencies after bariatric surgery can usually be prevented by taking high quality supplements as specifically directed by your surgeon, dietitian or nurse.
As outlined before, as a post bariatric surgery patient, you want to choose high quality supplements that will meet your needs. I’m quite often asked how much the supplements will cost and if bariatric formulated vitamins are necessary. Many years ago, we did not know as many details on the specific absorption of micronutrients after bariatric surgery and there were very few options for supplements; therefore, it was not uncommon for patients to be advised to take twice the recommended adult dose of Flintstones vitamins.
The field of bariatric surgery has advanced greatly over the past decade, and so have the quality and quantity of vitamin options for bariatric surgery patients. As detailed previously, the specific combination of supplements (multi- vitamin, iron, calcium, B12, etc.) will vary per individual; however, all post bariatric surgery regimens begin with a high quality multi-vitamin. The chart on the next page does not encompass all options available; it does compare several high quality, cost-efficient bariatric-formulated multi-vitamin options with a standard adult multi- vitamin (Centrum) and a children’s chewable (Flintstone’s Complete).
Vitamin deficiencies after bariatric surgery can be quite troublesome to correct, so don’t choose poorly based solely on cost.
