It is better to drink enzymes after meals. Enzymes are the products of fermentation of fruits and vegetables by microorganisms. If enzymes are consumed before meals, the stomach acid will increase, causing the appetite to rise and making the body fat. Moreover, if consumed before meals, some people may feel uncomfortable because of the contact between enzymes and stomach acid in the body. However, if consumed after meals, enzymes can help promote intestinal peristalsis, which is more conducive to digestion and reduce the symptoms caused by indigestion. Drinking enzymes after meals has a positive effect on human digestion and weight loss. However, long-term consumption of enzymes is not recommended. Although enzymes have positive effects on the human body, long-term consumption of enzymes will make the human intestinal tract dependent on them.
