Omega-3 fatty acids have been investigated as an adjunctive therapy for Sickle Cell Anemia (SCA), primarily due to their anti-inflammatory and membrane-stabilizing properties. Several small-scale clinical studies and pilot trials have evaluated the effect of omega-3 supplementation (usually EPA and DHA from fish oil) on SCA patients. The proposed mechanism is that omega-3s may decrease the frequency of vaso-occlusive crises by improving erythrocyte membrane flexibility, reducing blood viscosity, and modulating inflammatory cytokines involved in sickling episodes.

A few randomized controlled trials (RCTs) have reported that omega-3 supplementation can reduce the frequency of pain crises and hospitalization in children and adults with SCA. For example, a double-blind RCT published in Blood (2014) found a statistically significant reduction in painful episodes among children receiving omega-3 supplementation compared to placebo. However, these studies tend to have small sample sizes and some methodological limitations.

Despite these promising findings, the overall quality of evidence is moderate to low, and omega-3s are not universally recommended in clinical guidelines for SCA management. More large-scale, high-quality clinical trials are needed to confirm efficacy and determine optimal dosing. Thus, while there is scientific rationale and some preliminary evidence for the use of omega-3 fatty acids in Sickle Cell Anemia, current support remains modest.
