Week 7 Post Bariatric Surgery Instructions

Medically Reviewed by Katelyn J. Mock, US-Registered Dietician (R.D.)

Remember to take your recommended bariatric vitamins and minerals daily.

After bariatric surgery, your new stomach isn’t able to produce the same amount of gastric enzymes it could before to help you digest and absorb the nutrients in your food.

Week 7 Post Bariatric Surgery

You are also eating significantly fewer nutrients daily and need the extra vitamins and minerals to support your normal body functioning and aid with weight loss.

It is important to have your labs checked by your primary doctor at least once a year to make sure everything is within acceptable levels.

Daily Nutrient Dosage

Below are the guidelines by the American Society for Metabolic and Bariatric Surgery (ASMBS) for the amount of each nutrient that is recommended in your supplement.

Daily essential nutrient supplements

Separate taking your calcium from your iron-containing vitamin as they compete for the same absorption sites.
Take iron separately from calcium and avoid taking with acid-reducing medications.

Sample Bariatric Multivitamin Regimen

Below is an example of how you can organize your vitamin/mineral regimen:

Breakfast: Take a multivitamin, additional Iron, and sublingual B12

Lunch: 500 mg of Calcium + Vitamin D

Dinner: 500 mg Calcium + Vitamin D (if you haven’t already taken 3,000 IU)

Bedtime: 500 mg of Calcium + any remaining Vitamin D

If you notice that you have nausea with taking the iron supplement, try moving any iron-containing medications to before your bedtime snack.

Tip of the week: A pillbox can help keep you organized with what vitamins and minerals you need to be taking throughout the day, along with any other prescribed or over-the-counter medications you take regularly.
