I’ve been told that it’s not necessary to protect enzymes from stomach acid, is that right?
No. Many enzymes are sensitive to stomach acid and lose activity when held at a pH below 2.5 for an hour or more (typical time spent in the stomach). Lactase, for example, can lose 25% or more of its activity under these conditions, lipase even more. So protection from stomach acid is important and the gel-matrix formula used to Acid-Proof® ENZALASE® (patent pending) is a vital requirement to get full potency (declared enzyme activity units) through into the small intestine.
