Recent Advances in Lycopene Delivery Systems: Pharmaceutical, Nutraceutical, and Clinical Perspectives

Lycopene, a naturally occurring carotenoid found in tomatoes and other red-pigmented fruits, demonstrates strong antioxidant activity and therapeutic potential in cancer, cardiovascular disease, and inflammatory disorders. However, its clinical use is limited by poor solubility, instability, and low systemic absorption.

To overcome these limitations, various advanced drug delivery systems, including nanoemulsions, lipid-based carriers, hydrogels, and self-emulsifying systems, have been developed. Additionally, extraction techniques such as ultrasound-assisted and supercritical fluid extraction enhance lycopene recovery from natural matrices. Nanoformulations further optimize pharmacokinetics by improving solubility, stability, and targeted delivery.

These delivery strategies significantly enhance lycopene's absorption, bioavailability, and antioxidant activity while enabling sustained and targeted release. Preclinical and clinical findings support their efficacy in conditions such as prostate cancer, cardiovascular disease, and skin disorders.

The evidence highlights that optimized nanoformulations address lycopene's physicochemical limitations and broaden its translational potential. However, most data derived from preclinical studies, and limited clinical trials restricts definitive conclusions. Standardization in formulation, dosing, and evaluation remains as unexplored areas.

Lycopene-based delivery systems show strong promise for therapeutic and nutraceutical applications. Future directions include harmonized protocols, long-term safety studies, and large-scale clinical validation to bridge the gap between bench and bedside.
