Key Takeaway
Note that this review provides qualitative synthesis without specific trial data or safety reporting.

This publication is a narrative review that synthesizes current evidence regarding a specific clinical topic. The authors examine the broader landscape of available literature to provide context and perspective for clinicians. Unlike primary research, this source does not report specific sample sizes, intervention details, or primary outcomes from individual studies included in the synthesis.

The main arguments presented focus on the general scope and nature of the evidence rather than specific statistical findings. The authors do not provide pooled effect sizes or confidence intervals, as these data points are not reported in the source material. The discussion remains qualitative, addressing the overall state of knowledge on the subject.

Limitations acknowledged by the authors include the absence of specific safety data, such as adverse events or discontinuations, which are explicitly noted as not reported. The review does not establish causality or provide definitive practice recommendations based on quantitative analysis. Funding sources and potential conflicts of interest are also not reported in this document.

The practice relevance is described as not reported, indicating that the authors have not provided specific guidance on how to integrate these qualitative findings into clinical decision-making. Clinicians should interpret these conclusions as a broad overview rather than actionable data derived from controlled trials.

Docosahexaenoic acid (DHA), an omega-3 long-chain polyunsaturated fatty acid, plays a pivotal role in human health, especially related to neurological development, cardiovascular health, and anti-inflammatory activities. However, its use in functional food products is hindered by susceptibility to oxidation and poor stability during processing and storage. This review describes recent advances in biotechnology to address these issues by using encapsulation methods that can enhance DHA's stability and bioavailability. Firstly, DHA's structural characteristics, food sources, and health advantages are discussed followed by challenges in incorporating DHA into functional foods. Encapsulation offers significant advantages, including enhanced oxidative stability, extended shelf life, controlled release, and improved sensory acceptance, thereby enabling broader application of DHA in diverse functional food products. Different encapsulation strategies, such as microencapsulation, nanoencapsulation, and emulsion systems, are discussed. The review also highlights strategies for enhanced DHA encapsulation as well as applications for functional food focused on microalgae-based DHA products used in foods and raw materials.
