There is no authoritative information on when to eat enzymes, before or after meals can be eaten. Enzymes can provide nutrients for the body, should not be consumed in excess, and are prohibited for those who are allergic to enzyme ingredients. As a processed food, enzymes contain vitamins, polysaccharides, oligosaccharides, proteins, peptides and other nutrients. Eating enzymes before meals can increase satiety and help suppress appetite, which is suitable for people who want to lose weight. If you take enzymes after meals, you can also replenish the body with the nutrients it needs. Enzymes are made from fermentation using animals, plants, fungi and other substances as raw materials, so people who are allergic to enzyme ingredients should not consume enzymes to avoid rashes, itching, vomiting and other uncomfortable symptoms all over the body. It is also not recommended that the general population consume too much enzyme, which may cause abdominal pain, diarrhea and other digestive discomfort. There is no specific rule on when to eat enzymes, before or after meals can be eaten, the specific time to judge their own preferences.
