Abstract :
Curcumin, the primary polyphenolic compound from Curcuma longa (turmeric), alongside desmethoxycurcumin
and bisdemethoxycurcumin, exhibits potent anti-inflammatory, antioxidant, antibacterial, anticancer, and neuroprotective
effects. However, its therapeutic utility is hindered by poor aqueous solubility, chemical instability, rapid metabolism, and
low oral bioavailability (<1%). Nanotechnology addresses these limitations through advanced nanocarriers—including
liposomes, nano emulsions, polymeric micelles, dendrimers, polymeric nanoparticles, solid lipid nanoparticles, and
nanostructured lipid carriers—which enhance solubility, stability, gastrointestinal absorption, and site-specific drug release,
often achieving 20-50 fold bioavailability improvements. Gut microbiota profoundly modulates curcumin's
pharmacokinetics and efficacy in neurodegenerative diseases, cardiovascular disorders, cancer, and diabetic complications
by generating bioactive metabolites. Preclinical and clinical evidence supports curcumin's synergy with conventional
therapies, reducing adverse effects, while bioenhancers like piperine and structural analogs further optimize outcomes. This
review elucidates curcumin's tautomeric behaviour, metabolic pathways, microbiome interactions, and nanodelivery
strategies, emphasizing translational challenges such as scalability and safety. Harnessing nanotechnology and microbiome
modulation holds transformative promise for precision medicine applications.

Curcumin, the primary polyphenolic compound from Curcuma longa (turmeric), alongside desmethoxycurcumin
and bisdemethoxycurcumin, exhibits potent anti-inflammatory, antioxidant, antibacterial, anticancer, and neuroprotective
effects. However, its therapeutic utility is hindered by poor aqueous solubility, chemical instability, rapid metabolism, and
low oral bioavailability (<1%). Nanotechnology addresses these limitations through advanced nanocarriers—including
liposomes, nano emulsions, polymeric micelles, dendrimers, polymeric nanoparticles, solid lipid nanoparticles, and
nanostructured lipid carriers—which enhance solubility, stability, gastrointestinal absorption, and site-specific drug release,
often achieving 20-50 fold bioavailability improvements. Gut microbiota profoundly modulates curcumin's
pharmacokinetics and efficacy in neurodegenerative diseases, cardiovascular disorders, cancer, and diabetic complications
by generating bioactive metabolites. Preclinical and clinical evidence supports curcumin's synergy with conventional
therapies, reducing adverse effects, while bioenhancers like piperine and structural analogs further optimize outcomes. This
review elucidates curcumin's tautomeric behaviour, metabolic pathways, microbiome interactions, and nanodelivery
strategies, emphasizing translational challenges such as scalability and safety. Harnessing nanotechnology and microbiome
modulation holds transformative promise for precision medicine applications.
