What Are Omega-3s?
Omega-3 fatty acids are essential fats that play important roles in brain function, heart health, inflammation regulation, nervous system function, and overall cellular health. Because the body cannot efficiently produce them on its own, they must come from food or supplementation.
The three main forms of omega-3s are:
EPA (eicosapentaenoic acid)
DHA (docosahexaenoic acid)
ALA (alpha-linolenic acid)
EPA and DHA are the forms most commonly associated with research-backed health benefits and are primarily found in fatty fish and fish oil supplements.

Eye health
Mood regulation
Healthy inflammation balance
Recovery and overall wellness
Healthy aging
How Omega-3s Work in the Body
Omega-3 fatty acids become incorporated into cell membranes throughout the body, especially in the brain and nervous system.
DHA is a major structural component of the brain and retina, while EPA is often studied for its role in inflammatory signaling and cardiovascular support. Omega-3s also influence cellular communication and nervous system function.
Emerging research continues to explore omega-3s in relation to cognition, mood, and long-term brain health.
Who May Benefit From Omega-3s
Omega-3 supplementation may be useful for:
People who rarely consume fatty fish
Individuals focused on brain and heart health
Athletes and active individuals
Women supporting hormone and overall wellness
Individuals wanting additional nutritional support for healthy inflammation balance
Older adults focused on healthy aging
