What it is

Omega-3 is a group of essential fatty acids, which are healthy fats that the body cannot make on its own. Fish oil supplements specifically provide two important types called EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These are the active components that provide the nutritional benefits.

Why it's used

These supplements are primarily used to support heart health and brain function. They are often taken to help manage inflammation in the body or to support cognitive health. Because the body cannot produce these fats, they must be obtained through diet or supplements.

How it compares to Vegan Omega-3

While both provide essential fats, they differ in their source and how the body uses them.

How it's made

The process begins by taking raw fish oil, which is extracted from the fatty tissues of fish. This oil is then refined to remove impurities and pollutants. To make the supplement more effective, the oil undergoes a process called concentration, where the EPA and DHA are separated and increased in strength. Finally, the liquid oil is sealed into soft gel capsules for easy swallowing.

What it typically costs

This supplement is generally mid-range in price. This is because the cost depends on the quality of the fish sourcing and the complexity of the refining process required to ensure the oil is pure and concentrated.
