Fructaid® contains the enzyme glucose isomerase which helps the body digest fructose by promoting its conversion into glucose, that is easily absorbed in the small intestine.


Fructaid® is available as easy-to-swallow capsules. Within a few minutes, the capsules dissolve in the stomach and release glucose isomerase pellets which mix with the food pulp, while the glucose isomerase is still protected from gastric acid by a coating.*

Converts Fructose into Glucose

When the pellets enter the small intestine their coating dissolves and releases the enzyme in order to convert fructose present in the food pulp into easily absorbable glucose.*


The glucose isomerase enzyme is not absorbed from the small intestine and does not affect the body.*

No undesirable effects

Fructaid® only affects the food pulp, making it easier digestable through the conversion of fructose into glucose.*


Fructaid® is lactose-free, gluten-free, does not contain any material from animal origin, and hence suitable for vegans and vegetarians.

No Animal Ingredients

In a nutshell, Fructaid® is a microbial-based enzyme that turns fructose into glucose (grape sugar). No animal material is used in its manufacturing process.

Patent protected Fructaid® is protected by US patent number 8,460,911.
