Why extra vitamins?

This is why..

After your surgery, there are many changes in your body. You consume very little food and thus very few nutrients, while at the same time your body urgently needs this to continue functioning properly. That is why it is important that you complement your diet with extra vitamins, minerals and calcium supplements.

Your surgery
Sleeve or gastric band

After placing a sleeve, your stomach size is permanently reduced. The surgeon removes a large part of the stomach in length. The stomach (normally 1.5 liters) becomes a kind of tube with a much smaller volume. Your digestive tract remains intact. You are faster full after eating a small amount of food. During the day you consume less food and therefore fewer vitamins and minerals.

If you have a gastric band, your stomach is not permanently reduced. There’s a band around your stomach so that the upper portion becomes the size of a tangerine. This makes you feel satisfied and you eat less, so you no longer receive all the essential substances.

Gastric bypass

With this operation, your stomach is reduced and there is a so-called front stomach. This front stomach is directly connected to the second half of the small intestine. The biggest part of the stomach and the duodenum become ineffective. This means you are quickly full and eat less. This also means that you ingest fewer vitamins and minerals.

It is therefore important that you supplement your daily diet with the WLS Forte that is specially developed for people with a gastric bypass. With one capsule or chewable vitamin WLS Forte per day, your body is well supported.


A Biliopancreatic Diversion/Scopinaro Procedure (BPD) or Duodenal Switch (DS) is a heavy intervention which has major consequences for the intake of nutrients. In these operations, your stomach is reduced and the surgeon makes a kind of diversion. A large part of the small intestine no longer works. Moreover, you are more quickly full as a result of your smaller stomach. Supplementation with a multivitamin – especially vitamin B12, iron and vitamins A, D, E and K – is important.

With a single capsule of WLS Maximum per day, you can sufficiently supplement your diet with vitamins and minerals.
