Perque Repair Guard is a physician-grade antioxidant and tissue repair supplement formulated to support the body's natural healing processes — particularly the antioxidant protection, collagen synthesis, and cellular repair mechanisms required during injury recovery, post-surgical healing, and chronic inflammation management. 180 tablets.Quercetin provides broad-spectrum antioxidant and anti-inflammatory flavonoid activity — stabilizing mast cells to reduce histamine release, inhibiting the NF-κB inflammatory pathway, and providing powerful free radical scavenging. Vitamin C (mineral ascorbate) is the essential cofactor for collagen synthesis and tissue repair — required by prolyl and lysyl hydroxylase enzymes that cross-link collagen fibers. Bromelain (pineapple enzyme) reduces post-surgical and post-injury inflammation and supports tissue debridement. Alpha Lipoic Acid regenerates vitamins C and E after antioxidant use. Bioflavonoids amplify Vitamin C's antioxidant activity. Perque is a physician-grade clinical nutrition brand founded by integrative medicine pioneer Dr. Russell Jaffe, M.D., Ph.D., known for using only the highest-bioavailability nutrient forms (fully reduced, fully reacted) and rigorous quality standards.
