Curcumin, the main active ingredient found in turmeric (Curcuma longa), offers a wide range of beneficial pharmacological activities, including antioxidant, anti-inflammatory, and anti-cancer properties.However, its potential therapeutic benefits have been severely limited by its poor water solubility, which leads to very low oral bioavailability and rapid metabolism in the human body.Curcumin's hydrophobic nature causes its molecules to agglomerate in the body, resulting in minimal absorption in the gut, with most of it being excreted unabsorbed.Even when larger amounts of curcuminoids are provided through dietary supplements, ensuring adequate bioavailability remains a challenge.Traditional methods, like combining curcumin with piperine, have shown increased blood concentration, but this effect was short-lived, dropping quickly after only one hour.Why use cyclodextrin complexes?

Significantly Enhanced Bioavailability and Absorption: Cyclodextrins are naturally occurring oligosaccharides with a donut-shaped, three-dimensional structure featuring an inner hydrophobic cavity capable of encapsulating lipophilic molecules like curcumin. Their hydrophilic exterior ensures compatibility in aqueous systems, leading to molecular dispersions that greatly enhance curcumin's bioavailability. This allows a much larger number of curcumin molecules to be transported to the epithelial cell membrane in the upper intestinal tract for absorption.Human clinical studies have demonstrated that a cyclodextrin-based curcumin formulation was about 40 times more efficiently absorbed than pure curcumin extract and some leading commercial products.One clinical study found curcumin uptake to be at least 4.6 times higher than the next-best commercial curcumin formulation
