It might seem surprising, but even vegan omega supplements can sometimes have a slightly “fishy” taste or smell. This is actually normal and doesn’t mean the product contains fish or has gone bad.
Why it happens:
Vegan omegas are typically sourced from algae—the same original source that fish get their omega-3s from. Because of this, the natural compounds (like DHA and EPA) can carry a mild marine-like scent or taste. Another cause for this is that omega-3 fatty acids are delicate and can oxidize when exposed to air, light, or heat. This can slightly intensify the smell or taste over time, especially after opening.
Tips to minimize taste:
Take capsules with food
Store in the refrigerator or another cool dark place
Avoid leaving the bottle open for extended periods
