What vitamins can you not stop taking after bariatric surgery?

Have you already had surgery? Then there are vitamins you cannot leave out of your routine if you want to feel good and strong.

What vitamins can you not stop taking after bariatric surgery?

Bariatric surgery transforms your life… but also your way of absorbing nutrients. And no matter how healthy you eat, after a procedure like gastric sleeve or bypass, the body no longer retains essential vitamins and minerals the same way.

Therefore, taking specific supplements is not optional, it is part of the treatment. Here we explain which are the most important and what happens if you skip them.

The 5 vitamins and minerals you must take

1. Vitamin B12

Essential for the nervous system, energy, and red blood cell formation. Most operated patients do not absorb it well through traditional oral means, which is why it is recommended in sublingual, liquid, or high-potency capsule form.

• Common deficiency: fatigue, tingling, memory loss.

• Suggested dose: 500 to 1,000 mcg per day (as per medical advice).

2. Iron

Surgery reduces iron absorption, especially in menstruating women. A chelated form or with vitamin C is recommended to improve absorption.

• Common deficiency: anemia, paleness, weakness.

• Tip: Avoid taking it with calcium (they compete for absorption).

3. Vitamin D

Key to absorbing calcium and keeping your bones strong. Many people already have a deficiency before surgery, and this can worsen afterwards.

• Benefits: strong bones, immunity, mood.

• Recommendation: combined with calcium and in adequate doses.

4. Calcium

The lack of calcium post-surgery can lead to bone demineralization. It is better to take it in the form of calcium citrate, which is easier to absorb.

• Common deficiency: bone pain, loss of bone mass, weakness.

• Tip: divide the dose throughout the day.

5. Bariatric multivitamin

Not just any multivitamin works. You need one designed especially for bariatric patients, with high doses of micronutrients in easily absorbable forms (like those from Bariatric Fusion).

• They include: A, E, K, zinc, biotin, thiamine, folic acid, and more.

• Recommended forms: chewables, powder, or small capsules.

What happens if you stop taking them?

Skipping your vitamins may seem "not that serious" at first, but over time it can lead to invisible deficiencies that end up in:

• Chronic fatigue

• Severe hair loss

• Anemia

• Muscle pain

• Fractures due to loss of bone density

• Neurological problems

👉 If you are already feeling any of these symptoms, the best thing is to review your supplementation plan with a professional.

And how long should I take them?

All your life.
Your new digestive system will not absorb the same way again. That's why consistency with your supplements is what will make the difference between feeling good or living with unnecessary discomfort.

Bariatric surgery is a profound change. But taking care of yourself doesn't end in the operating room. Your consistency with supplements is what will allow you to:

✅ Recover better
✅ Maintain your energy
✅ Take care of your hair, skin, and bones
✅ Prevent medical emergencies
