Overview

In plain language

Omega-3 fatty acids are essential fats that support cardiovascular, brain, and joint health. They reduce inflammation and improve heart rhythm stability in older adults.

Found in fish oil and plant sources like flaxseed, omega-3s (EPA and DHA) play key roles in heart and brain function. They help regulate triglycerides, reduce joint inflammation, and support mood balance. Regular intake is associated with lower risk of heart disease and cognitive decline. For seniors, omega-3 supplementation provides foundational support for cardiovascular and mental well-being.
