What is Doctor’s Best Curcumin C3 Complex? Doctor’s Best Curcumin C3 Complex is a potent antioxidant that protects cells and tissues by fighting free radicals. It is also proven to support healthy joint function. Curcumin C3 Complex contains a standardized extract of Curcuma longa root and supplies 95% total curcuminoids, including curcumin, bisdemethoxy curcumin and demethoxy curcumin. As curcumin is difficult to absorb we add, BioPerine, an extract of Black Pepper fruit that contains 95-98% piperine, as a natural bioenhancer. How does it work? Extensive research over the past quarter-century suggests that curcumin can help counter toxins and influence cell survival through other means. Due to the potent radical-scavenging activity of the curcumins, cultured human skin cells subjected to free radical attack fared better when curcumin or a mixture of the three major curcumins was administered. Furthermore, the three curcumins combined had a greater effect than an equal amount of curcumin, which has led some scientists to claim a synergistic effect from the combination. Why should I take Doctor’s Best Curcumin C3 Complex? The numerous beneficial effects attributed to turmeric root are related to the antioxidant properties of the curcumins it contains. This antioxidant activity can neutralize free radicals that threaten the integrity of cellular structures. Free radicals can cause “oxidative stress,” a process that can trigger cell damage. And oxidative stress is thought to play a role in a variety of diseases. Curcumin C3 Complex has over 50 scientific studies to validate its effectiveness.
