Innovative drug delivery systems enhance omega-3 and omega-6 fatty acids oral administration. These advanced methods improve stability, absorption, and clinical efficacy for essential fatty acids.
Area of Science:
- Nutritional Science
- Pharmacology
- Biotechnology
Background:
- Omega-3 and omega-6 fatty acids are vital for health, used in treating cardiovascular diseases, inflammation, and metabolic disorders.
- Oral administration of these polyunsaturated fatty acids is hindered by low solubility, oxidation, and poor bioavailability.
- Current delivery methods limit the full therapeutic potential of essential fatty acids.
Purpose of the Study:
- To review recent advancements in oral drug delivery systems for omega-3 and omega-6 fatty acids.
- To analyze how novel technologies improve the stability, absorption, and clinical performance of these essential fatty acids.
- To discuss natural sources, extraction, purification, and metabolism challenges of omega-3 and omega-6.
Main Methods:
- Comprehensive literature search (2015-2025) in PubMed, Scopus, and Web of Science.
- Narrative review focusing on innovative delivery technologies.
- Comparative analysis of conventional versus modern delivery strategies.
Main Results:
- Nanoemulsions, liposomes, microencapsulation, and solid lipid nanoparticles (SLNs/NLCs) show promise in enhancing fatty acid delivery.
- These systems improve stability, bioavailability, and therapeutic outcomes compared to conventional methods.
- Emerging approaches offer optimized utilization of omega-3 and omega-6 in the body.
Conclusions:
- Advanced oral delivery systems can overcome limitations of essential fatty acids.
- These technologies have the potential to revolutionize fatty acid administration in medicine and nutrition.
- Future research and regulatory considerations are crucial for widespread adoption.
