reviews

Great! I can now eat things I couldn't eat before. I am impressed, thank you!

Maria

I don't have to cook for myself separately anymore. I can eat what my husband and daughter eat. I love the Quatrase. Thanks!

Natalie

After 3 years of not being able to eat everything, my 10 year old daughter was able to eat her first piece of cake! She is so happy! Great product.

Tara

It's so nice that I can eat outside the house again. Seriously an amazing product!

Jelle

This product works very well. It is wonderful how I can enjoy my food again without any worries.

Hilde

I am very satisfied with these lactase drops! I can drink milk products again and even make probiotics lactose free without being affected by it. The taste of the products does not change. It becomes a little bit sweeter without losing the original taste, which is ideal for the products with no lactose free alternative!

Ann

My four year old daughter is all smiles! After day five, she could eat and drink anything! Croissants, ice cream, yogurt drink, and we can cook anything we want. A really top-notch product! The first box is almost finished and we are going to order new ones right away. Excellent product.

I think I have found "THE" product. After much reading and searching, I ended up with Fibractase. I immediately tested it and so far I have no problems.
