what are digestive enzymes?

Digestive enzymes play an essential role in breaking down and digesting nutrients, such as complex carbohydrates (sugars). These specific enzymes ensure that complex carbohydrates are broken down into simpler sugars that the body can digest more effectively. If these complex sugars are not broken down, it can lead to side effects such as gas formation and fermentation, which can be quite discomforting.

why choose Quatrase?

Quatrase contains a blend of various digestive enzymes that assist in the digestion of different hard-to-digest carbohydrates. For example, lactase helps in the digestion of lactose, and the enzyme alpha-galactosidase aids in the digestion of complex carbohydrates (fructans and galactans).

Unique blend of highly dosed digestive enzymes
