Interaction rules involving Omega-3
PairSeverityMechanismAction
Fish oil (EPA/DHA) × WarfarinModerateEPA and DHA displace arachidonic acid and reduce thromboxane production, which prolongs bleeding time on top of warfarin.Doses up to 2 g combined EPA+DHA are usually tolerated; higher doses need prescriber awareness and INR check.Source
Fish oil (EPA/DHA) × Direct anticoagulantMildOmega-3 fatty acids have mild platelet-inhibiting effects that add to anticoagulant action.Keep doses moderate and flag any new bruising to your prescriber.Source
Vitamin D3 softgel × Fish oil (EPA/DHA)SynergyBoth are fat-soluble and require dietary fat for micelle formation and lymphatic absorption. Taken with fat, each improves the other’s uptake.Take vitamin D3 and fish oil in the same meal that contains at least 10-15 g of fat.Source
