We offer the best nutritional supplements for our patients and their individual needs

Every human being has the genetic potential to live a healthy life. Whether we also use our full health potential depends on various factors: our lifestyle, diet and environment. We want to offer the best nutritional supplements for our patients and their individual needs. 

At Bariatric Advantage, we closely follow the latest international guidelines and scientific publications to provide you with the best solution.

Since deficiencies are not only dependent on the type of surgery, but may differ individually as well, we offer a complete specific multivitamin in the right dosage, which prevents or replenishes most deficiencies. In case of particular individual needs, supplementation of separate products may offer a solution.

Curious about how we do it?

Optimal absorption

  • The best ingredients in the right form
  • Without discomfort

Much more than a standard nutritional supplement

"In addition to product quality, an important factor is bioavailability. When we take a substance, such as a vitamin or mineral, it has to travel through the body to where it is needed. Along the way, some of the original amount may be lost, for example because of stomach acid or because the intestines cannot absorb it all. Our job is to find the form of the substance that gets the most of it to where it is needed. " Mieke Van Den Driessche, VP of Global Science/R&D at Metagenics.
