What is the principal Omega-3 fatty acid called?

The principal Omega-3 fatty acid is indeed Alpha Linolenic Acid (ALA). ALA is considered essential because the body cannot synthesize it and must obtain it through diet. It plays a crucial role in maintaining cellular health and contributes to various bodily functions, including heart health, anti-inflammatory processes, and cognitive function.

Other Omega-3 fatty acids such as Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA) are also important but are typically derived from ALA. These two are often found in marine sources and are recognized for their specific benefits related to brain health, cardiovascular function, and reducing inflammation.

Linoleic Acid, while an important fatty acid, is classified as an Omega-6 fatty acid rather than an Omega-3, highlighting the distinct biochemical pathways and roles that these fatty acids play in the body. Thus, among the choices provided, ALA stands out as the primary Omega-3 fatty acid essential for human health.
