Live Enzymes vs Dried Enzymes: What's the Difference?
The Basics of Enzyme Activity
Enzymes are proteins that catalyse specific biochemical reactions. Their effectiveness depends on their three-dimensional structure remaining intact. When enzymes are exposed to excessive heat, harsh chemicals, or prolonged storage in unfavourable conditions, they can denature, losing their functional shape and their ability to catalyse reactions.
How Dried Enzyme Supplements Are Made
Most enzyme supplements on the market use enzymes that have been extracted, purified, and then spray-dried or freeze-dried into a powder. This process can reduce enzyme activity. Some products compensate by adding higher initial concentrations, but the fundamental issue remains: the enzymes are no longer in their native, active state.
What Makes a "Live" Enzyme Different
A live enzyme supplement maintains enzymes in a metabolically active state within their fermentation matrix. Rather than extracting and drying the enzymes, the entire fermented substrate is preserved. This approach keeps the enzymes in the environment where they were produced, maintaining their structural integrity and catalytic activity.
Why It Matters in the Gut
The equine digestive tract is a dynamic environment with varying pH levels, temperatures, and transit times. Enzymes that arrive in an already-active state can begin working immediately upon contact with their substrate. Dried enzymes may need to rehydrate and refold before they become functional.
Measuring the Difference
Enzyme activity is measured in units per kilogram (U/kg). This measurement reflects how much substrate an enzyme can process in a given time under standardised conditions. When comparing supplements, the U/kg figure is more meaningful than the total weight of enzyme powder.
