Enzyme Science Enzyme Defense Pro is a systemic enzyme formula designed for immune support and daily wellness — combining enteric-coated protease enzymes with Vitamin D3, L-Lysine, and Calcium for a comprehensive immune and anti-viral enzyme defence formula. 60 capsules.Systemic proteolytic enzymes (taken away from food on an empty stomach) absorb into the bloodstream where they perform immune-modulating and anti-inflammatory functions — breaking down immune complexes and fibrin accumulation, reducing the inflammatory protein load that taxes the immune system. L-Lysine competes with L-Arginine for cellular uptake, reducing the amino acid environment that viral replication (particularly herpes family viruses) requires. Vitamin D3 supports over 200 immune-relevant gene expressions and T-regulatory cell function. Calcium supports cellular signalling in immune responses. Enzyme Science is a professional-grade enzyme supplement brand using proprietary Thera-blend™ technology — formulating enzymes that remain active across the full pH range of the digestive and systemic environments. Available at Beauty Riche with same-day shipping.
