Fish Oil

A marine source of concentrated omega-3 fatty acids extracted from oily fish.

Definition

Fish oil is a dietary supplement derived from fatty fish tissues, rich in omega-3 polyunsaturated fatty acids, particularly EPA and DHA.

How it works

Fish oil comes from species like salmon, mackerel, and sardines that accumulate omega-3 fats through their diet. These fish are not actually producing omega-3s themselves, but rather concentrating them from smaller organisms in the food chain. Fish oil supplements are processed to extract and concentrate these beneficial fats, making them a convenient way to increase omega-3 intake without eating large quantities of fish. The oil is typically available in liquid, capsule, or soft gel forms for easy consumption.

Role

Supports cardiovascular health, reduces inflammation, and promotes brain function through EPA and DHA content.

Examples

  • Salmon oil
  • Cod liver oil
  • Sardine oil
  • Mackerel oil

Recommendations

Choose molecularly distilled fish oil to minimize contaminants. Aim for 1-3 grams of combined EPA/DHA daily, taken with meals to enhance absorption. Store in a cool, dark place to prevent oxidation.

Key takeaway

Fish oil is an efficient way to obtain high-quality omega-3 fatty acids, though sustainable sourcing and freshness matter significantly.
