Review reveals sex-specific limits in alpha-linolenic acid conversion to longer-chain fatty acids in adults, suggesting dietary intake of preformed omega-3s is critical.

Key Points

To evaluate human alpha-linolenic acid metabolism, conversion capacity to long-chain polyunsaturated fatty acids, and sex-specific metabolic differences.
Synthesized findings from human trials employing stable isotope tracers to trace fatty acid elongation and desaturation pathways.
Assessed metabolic partitioning toward beta-oxidation and carbon recycling under varying dietary alpha-linolenic acid intakes.
Conversion of alpha-linolenic acid to eicosapentaenoic acid is limited in men, with subsequent transformation to docosahexaenoic acid remaining extremely low.
Women utilize a lower proportion of alpha-linolenic acid for beta-oxidation and achieve higher fractional conversion to long-chain polyunsaturated fatty acids than men, likely mediated by estrogen.
