TLDR High DHA levels delay wound healing and worsen skin repair quality.
The study found that increased levels of docosahexaenoic acid (DHA) in mice, both endogenously produced in FAT-1 transgenic mice and supplemented with DHA-rich fish oil, slowed the resolution of inflammation and impaired the quality of healed skin tissue. This was evidenced by prolonged inflammation, increased inflammatory markers like TNF-α, and altered collagen fiber organization. Despite DHA's known anti-inflammatory properties, its elevated levels led to delayed wound healing and poor tissue quality, suggesting a need for caution in DHA supplementation, especially when tissue repair is critical. The study included 8-16 mice per group, providing a robust sample size for these findings.
