Fucoxanthin, a Functional Food Ingredient: Challenges in Bioavailability.

Area of Science:

• Nutritional Science
• Marine Biotechnology
• Pharmacology

Background:

• Fucoxanthin, a xanthophyll carotenoid from brown seaweeds, exhibits significant bioactivity.
• Potential health applications include anti-cancer, anti-diabetic, and anti-obesity effects.
• Poor bioavailability and gastrointestinal instability limit fucoxanthin's therapeutic use.

Purpose of the Study:

• To review the challenges in fucoxanthin absorption.
• To explore the role of micro- and nano-encapsulation in enhancing fucoxanthin bioavailability.
• To highlight encapsulation as a strategy to overcome fucoxanthin's limitations.

Main Methods:

• Review of scientific literature on fucoxanthin bioavailability and encapsulation.
• Analysis of lipid-based encapsulation systems (liposomes, nano-structured lipid carriers).
• Evaluation of studies demonstrating enhanced fucoxanthin solubility and absorption.

Main Results:

• Encapsulation significantly improves fucoxanthin solubility and bioavailability, with reported increases from 25% to 61.2%.
• Lipid-based systems effectively protect fucoxanthin from degradation in the gastrointestinal tract.
• Micro- and nano-encapsulation are key strategies for enhancing intestinal absorption.

Conclusions:

• Encapsulation is a viable approach to overcome fucoxanthin's poor bioavailability and instability.
• Enhanced fucoxanthin delivery through encapsulation can unlock its full therapeutic potential.
• Further research into optimized encapsulation techniques is warranted for pharmaceutical applications.
