Vitamin and Mineral Supplements After Gastric Band and Balloon Insertion

After your band or balloon

After your surgery you will need to take a complete multivitamin and mineral supplement every day for life (or for as long as you have a gastric band or balloon). Some multivitamins and minerals can be prescribed by your GP. Alternatively you can purchase some over the counter from pharmacies and supermarkets.

How much should I take?

Follow the instructions on the particular products packaging. However the dose for the majority of multivitamins and minerals is one capsule each day.

Why do I need to take a multivitamin and mineral every day?

After your surgery, you will begin to eat less than you did before. In the long term this can result in an inadequate intake of vitamins and minerals. Taking a daily multivitamin and mineral may help to supplement your intake and reduce the risk of deficiencies.

When should I start taking a multivitamin and mineral?

Start as soon as possible after your band insertion or balloon. If possible, take your supplement just before or after food as this may reduce side effects such as nausea.


If you are planning a pregnancy you will need to ensure that your vitamin and mineral is suitable. During pregnancy you will need to avoid any supplements containing Vitamin A (in the form of retinol). Pregnancy specific multivitamins and minerals are suitable or any that contain Vitamin A in the form of beta carotene. Please speak to your Dietitian if you need advice.
