About this food

Fish oil is a common member of Condiments & Oils. Sodium varies hugely across condiments and oils - soy sauce and sauces are sodium-dense while most plant oils are nearly sodium-free. Swapping salty sauces for oils is a practical sodium trick. This helps when choosing similar foods.

Nutrient insight

Fish oil's phosphorus (<1%) is worth noting - especially with Processed additive (highest absorption) as the source, since absorption differs a lot.
