The Mold Question

Q: Are your enzymes grown on aspergillus and is there any aspergillus or mold in the enzyme product? 

A:  First, let's get the wording correct.  

Enzymes are not "grown on" Aspergillus, they are secreted from different strains of fungi which include Aspergillus niger, Aspergillus oryzae, and Trichoderma reseei.  

Fungi release enzymes from their bodies so as to break down whatever they use for growth.  

Think of the fungi as sponges and enzymes would be the liquid being released. The enzymes we and every other enzyme company use are highly purified and do not contain any of the fungal material associated with mold allergies.  

After 10 -12 different purification procedures, all that is left is pure enzyme protein. There are no spores or harmful mold present.

Some say that taking enzymes causes them to react negatively and they also have mold allergies, therefore, the enzymes must have aggravated or caused their allergic reaction.  This is not necessarily the case. Enzymes are unique proteins and anyone can develop an allergy or react to any protein.

If you take an enzyme and you have some type of allergic response, it may be that you are specifically allergic to one or more of the enzyme proteins in that product.  You may be able to tolerate other types of enzymes.

We have many customers who have mold allergies and are allergic to Aspergillus but can take enzymes with no problems.  We have had other customers with no mold allergies who have reacted to certain enzyme products yet tolerate other fungal enzymes.

Keep in mind that most enzyme companies obtain enzymes from the same sources. The differences in products come from which enzymes and at what activity levels are used.
