Buying Guide: What to Look for in a Digestive Enzyme Supplement
Enzyme Diversity and pH Range
Not all digestive enzymes work the same way. The human digestive tract has varying pH levels from the acidic stomach to the more alkaline small intestine. A supplement with enzymes active across a broad pH range can support digestion at every stage. Integrative Therapeutics Similase includes microbial enzymes that remain effective from pH 2.0 to 9.0, covering the entire digestive journey. This broad activity ensures that carbohydrates, proteins, fats, and fibers are broken down efficiently regardless of where they are in the gut. For a deeper look at how enzymes function, check out our complete guide on how digestive enzymes work.
Vegan and Allergen Friendly Formula
Many digestive enzyme supplements are derived from animal sources like pancreatin or pepsin. For those following a vegan or plant-based lifestyle, that is not ideal. Integrative Therapeutics Similase is entirely vegan, using microbial enzymes cultivated from fungi and bacteria. It also contains no dairy, artificial colors, flavors, or preservatives. This makes it a clean option for individuals with multiple food sensitivities.
