Digestive enzymes are objectively important for good digestion, though the effect of an enzyme supplement depends on the ingredients it contains and whether it is appropriate for your digestive issue. If you have digestive symptoms due to an enzyme deficiency or intolerance, supplementing with the particular enzyme responsible for the nutrient you are malabsorbing can improve symptoms.   “Not all enzyme formulas are created equally and may be targeting different foods,” Dr. Pashinsky says, “so having an understanding of the product, and the expectations one should have from it, is key.”
