Non GMO The Enzyme Experts Most Advanced Formerly ViraStop 2X Therapeutic #1 Selling Enzyme Brand Most Advanced Immune System Support Extra Strength Proteolytic Enzymes Supports Systemic Health Dietary Supplement Vegan & Kosher Kosher Parve The immune system is constantly faced with the challenge of protecting the body from environmental threats. Nearly all threats contain a protein component that the immune system must identify and break down. Enzymes that break down protein (proteolytic) can support this immune process. When the immune system is functioning optimally, systemic health is enhanced. Enzyme Defense Extra Strength is two times the potency of Enzyme Defense. The formula has an enzyme blend that provides support to purify the body and assist in removing proteins that do not belong in the bloodstream. This allows the immune system to focus on areas of need. Additional enzymes are included to break down excess mucus and promote healthy circulation. Enzyme Defense Extra Strength is not an "immune stimulator," rather a supporter of healthy immune function. Thera-blend is an exclusive process that combines multiple strains of enzymes that work in specific pH levels, resulting in superior performance in the body.
