Analyzed variants (SNPs)

rs1535 FADS2 Population frequency: 35.0%
Genotype Impact What it means
AA (Normal) Normal Efficient omega-3 conversion from plant sources (ALA to EPA/DHA).
AG (Carrier) Low impact Moderate omega-3 conversion. Mix of plant and marine omega-3 sources recommended.
GG (Variant) Moderate Poor omega-3 conversion. Direct sources (fatty fish, fish oil) recommended over plant sources.
