Bariatric Multivitamins

You have had weight loss surgery, and now the vitamin aisle looks like a maze. Iron level, capsule or chewable, and extras like probiotics all change what suits you. This page walks through the main kinds of bariatric multivitamin so you can match one to your needs, and talk it over with your care team.

Standard iron capsules (18 mg)

Some people do not need a high dose of iron. The 18 mg capsule is described as standard-dose iron for patients who do not need a high dose. It still covers all the essential nutrients in one capsule a day. If your care team has told you your iron is fine, this is the lower-iron option in the range.

High iron capsules (45 mg)

The 45 mg iron capsule is the core formula here. It is made for bariatric surgery patients, one capsule per day, and it is described as meeting ASMBS 2016 rules for nutrients after weight loss surgery. It suits anyone whose plan calls for more iron. The same formula also comes in a 90 count bottle, which is a three month supply and means fewer reorders.

Iron free capsules

Some people take iron on its own, or find iron hard to tolerate. The iron free version gives 21 key vitamins and minerals in one small capsule, once a day. It lets you manage iron separately, in whatever amount your care team sets.

Chewables

Swallowing capsules is not everyone's preference, especially in the early weeks after surgery. The citrus chewable has 45 mg of iron and is described as a good fit if you prefer chewing to swallowing. It is a 30 count pack, so one a day for a month.

Multivitamins with probiotics or prenatal support

Two capsules add something extra. One puts five probiotic strains into the daily multivitamin, so there is nothing more to take. The other is made for mothers who have had weight loss surgery. It has 60 mg of iron, probiotics and 24 key vitamins and minerals, in one vegetarian capsule a day. Both come in 60 count bottles.

Biotin on its own

Biotin is not a multivitamin, but it often sits beside one. This capsule has 5 mg of biotin and is described as small and easy to swallow. The retailer notes biotin plays a role in the metabolism of protein, fat and carbs, and may help support healthy hair and nails. Treat it as an add-on, not a replacement.

How to choose

• Iron level first. The range runs from iron free, to 18 mg, to 45 mg, with 60 mg in the prenatal. Pick the one your care team's advice points to.
• Format. Small capsules suit most people. Chewables suit those who would rather chew.
• Extras. Probiotics and prenatal support are built into specific products. Only pay for them if you want them.
• Bottle size. A 90 count bottle lasts three months. A 30 count bottle is easier to try first.
• Check the label. Read the full supplement facts before you buy.

Questions people ask

Do I need a bariatric multivitamin, or will a regular one do?

These products are made for bariatric patients and one is described as meeting ASMBS 2016 rules. Ask your surgeon or dietitian what they want you to take.

Can I take biotin with a multivitamin?

Many people do, as the biotin capsule is sold as a separate add-on. Check the label of your multivitamin and ask your care team if unsure.

What if iron upsets me?

The iron free capsule is described as a good fit if you are sensitive to iron or take it separately. Talk to your care team before changing your iron intake.

How many do I take a day?

The capsules are described as one per day. Follow the directions on your bottle and your care team's advice.
