The Best Bariatric Multivitamins

A Guide to Choosing the Best Bariatric Multivitamins

Bariatric surgery procedures restrict food intake and reduce the amount of nutrients the body can absorb. This makes it essential for bariatric patients to take specialized multivitamins to prevent nutritional deficiencies. Selecting a high-quality bariatric multivitamin is so important for maintaining health after surgery. This article provides a complete guide to choosing the best bariatric multivitamin.

Things to Look for in a Bariatric Multivitamin

When selecting a bariatric multivitamin, there are several key features to look for:

  • High potency - Bariatric multivitamins contain higher amounts of certain vitamins and minerals compared to standard multivitamins. Look for a formula with increased levels of iron, calcium, vitamin B12, folic acid, and other nutrients.

  • Proper formulations - The vitamins and minerals need to be in forms that are readily absorbed by the altered GI tract post-surgery. Forms like chelated minerals, methylated B vitamins, and emulsified fat-soluble vitamins have enhanced absorption.

  • Minimal additives - Avoid multivitamins with unnecessary fillers like sugar, starch, artificial flavors, or binders. These can interfere with absorption. Go for a clean formula.

  • Small pills - Pills should be small and easy to swallow. Bariatric patients often have difficulty swallowing larger pills. Chewable is also a good form of bariatric multivitamin.

Recommended Nutrients and Doses for Bariatric Patients

Specialized bariatric multivitamins are highly recommended after bariatric surgery because patients have an increased risk for developing certain vitamin and mineral deficiencies. Selecting a high-quality bariatric multivitamin formula with increased levels of the key nutrients prone to deficiency is an important component of follow-up care.

Here is a list of common nutritional deficiencies after bariatric surgery with a brief explanation of each:

Vitamin/Mineral Recommended Daily Value Importance for Bariatric Patients

Biotin (Vitamin B7) 600 mcg Also known as the beauty vitamin, biotin is essential for better hair, skin, and nails and supports metabolic processes, which is essential after weight loss surgery.
B Vitamins (Vitamins B1, B2, B5, B6) 12 to 20 mg Critical for healthy skin, hair, muscles, nervous system, and brain function. Essential in the process of converting carbohydrates into energy.
Vitamin A (from Beta Carotene & Vitamin A Acetate) 3,300 mcg Used to form and maintain healthy teeth, bones, skin, and soft tissue.
Vitamin D (Calciferol) 75 mcg, 3,000 IU The sunshine nutrient. A lack of vitamin D can cause bone deficiencies and other diseases. Required in high doses after bariatric surgery and is best absorbed with calcium.
Chromium (as Chromium Picolinate) 100 mcg Helps maintain healthy blood glucose levels and converts glucose into energy, essential for patients with diabetes.
Vitamin E (as D-alpha tocopheryl succinate) 40.2 mg An essential nutrient in wound healing, aids in the production of red blood cells and assists vitamin K in the healing of wounds and scars.
Iron (from Ferrous Fumarate) 45 mg Common vitamin deficiency after bariatric surgery and the most probable reason for post-bariatric anemia, iron is essential in producing red blood cells and making amino acids.
Niacin (Vitamin B3) 40 mg Helps maintain healthy skin, nerves, and brain and plays a vital role in lowering cholesterol levels.
Copper (from Copper Gluconate) 2 mg Aids in metabolizing iron and supporting your immunity.
Folic Acid (L-Methylfolate Calcium) 800 mcg An essential nutrient in the production of DNA and vital for women of childbearing age as a lack of folate can result in birth defects.
Selenium (Selenium Amino Acid Chelate) 100 mcg Helps fight oxidative stress that could result in chronic health conditions such as heart disease and cancer. Low selenium levels in post-bariatric patients could result in cardiomyopathy.
Molybdenum (as Molybdenum Amino Acid Chelate) 75 mcg Helps break down unhealthy toxins in the body.
Zinc (Zinc Oxide and Zinc Amino Acid Chelate) 16 mg Critical to the support of a healthy immune system and optimal metabolic control.
Vitamin C (L-ascorbic acid) 130 mg The immunity mineral, vitamin C bolsters the immune system and plays a vital role in wound healing and the regeneration of antioxidants.
Vitamin K (Phytanadione) 120 mcg An essential nutrient in the blood clotting process and assists wound healing after bariatric surgery.
Iodine (as Potassium Iodide) 150 mcg Essential to thyroid control by regulating your metabolism for weight and energy control. Iodine also promotes skin repair and slows down the appearance of aging.

(Note: The recommended daily values are general recommendations. Bariatric patients should consult with their healthcare provider for personalized recommendations.)

When searching for the best bariatric multivitamins, compare nutrient amounts to find one that best fits your needs. Also consider pill form (chew, capsule, etc) and costs.

Additional Vitamin Tips for Bariatric Patients

  • Take your bariatric multivitamins and supplements exactly as instructed by your post-surgery care team. They will provide directions on dosage, timing, and which nutrients need separate supplementation. Consistency is key - set reminders if needed.
  • Get regular bloodwork to monitor your nutritional status and catch any deficiencies early before complications arise. Testing key nutrients like iron, B12, folate, calcium, vitamin D, and protein helps your team adjust supplementation as needed.
  • Consider monthly vitamin B12 injections for better absorption compared to oral doses. Intramuscular injections bypass the digestive tract's role in absorption. High-dose vitamin D3 supplementation is also recommended for optimal bone health.
  • Chew vitamins thoroughly or allow tablets to fully dissolve under the tongue for better breakdown and absorption. Taking on an empty stomach may also aid absorption.


Selecting the right bariatric multivitamin tailored to your needs and following medical advice is so important for maintaining health and preventing deficiencies after bariatric surgery. Look for a high-potency formula with increased levels of key nutrients. Be aware of deficiency symptoms and follow up with your care team regularly. Taking quality bariatric vitamin supplements can help ensure you get the most benefit from your bariatric procedure.

Frequently Asked Questions

Why do I need a special bariatric multivitamin?

Bariatric surgery reduces the amount of food and nutrients your body absorbs. Standard multivitamins won't provide the higher doses you need post-surgery. Bariatric formulas have increased vitamins/minerals and forms to prevent deficiencies.

When should I start taking bariatric supplements after surgery?

Most experts recommend starting a complete bariatric multivitamin and additional key supplements (calcium, vitamin D, B12, etc) 2 weeks after surgery as tolerated. Follow your surgeon's instructions.

How long do I need to take bariatric supplements?

You will likely need to take specialized bariatric vitamin and mineral supplements for at least 18-24 months after surgery. Some people require lifetime supplementation depending on their needs.

Can I just take a standard OTC multivitamin?

OTC regular multivitamins do not contain the right nutrients at the increased doses needed after bariatric surgery. They can lead to deficiencies over time. Stick to specific bariatric formulations.

What's the difference between capsules, chewables, and liquids?

Chewables, liquids, and melts may offer better absorption for some. Capsules are more convenient. Choose whichever type you can reliably take daily.

How do I know if a supplement is high quality?

Look for independent testing, cGMP certification, solid company reputation, good customer reviews, and recommendations from your bariatric team.
