Vitamins & Nutrition

Weight loss surgery decreases the body’s ability to absorb vitamins and nutrients and/or restricts the amount of food you can consume. This can result in malnutrition, or vitamin and mineral deficiencies, that can be damaging to your health.

Vitamins and minerals are needed after surgery so the body can heal properly. Note: All patients should take daily vitamins for a lifetime to avoid nutritional deficiencies.

Chewable, liquid or crushed forms of vitamins are preferred for the first 6 weeks during the liquid and soft diet phase.

Transition to tablets or capsules is appropriate at that point.

Gummy vitamins should be avoided due to added sugars and insufficient vitamin contents.

Vitamin Patches are not recommended due to unclear effectiveness.

Your vitamin levels should be checked beginning at 6 weeks and then periodically to ensure proper supplementation and avoid deficiencies.

Over the counter multivitamin must be complete and should contain iron. Should contain at least 200% Daily Value for most contents. Specialized Bariatric Multivitamins may prevent the need for additional vitamin D or B supplementation.

Calcium citrate is the preferred form due to better absorption. Calcium should include vitamin D. Individual dose should be 500-600 mg taken 2-3 times per day. Should not be taken with iron (whether contained in multivitamin or additional iron supplement) due to absorption problems.

Vitamin D
You may need additional vitamin D 3000-5000 IU per day if instructed to do so.

Vitamin B-12
You may need additional vitamin B-12. Options include 1000 mcg sublingual daily, 500 mcg nasal spray weekly, 1000 mcg injection monthly.

Vitamin B-1 (Thiamin)
A B-complex vitamin 50 mg daily may be recommended.

Additional iron may be needed particularly for menstruating females or for patients with anemia. Should not be taken with calcium due to absorption problems.
