What is Omega-3?

Omega-3 fatty acids are a type of polyunsaturated fat that are essential for human health. They play a crucial role in brain function, normal growth and development, and inflammation reduction. The body cannot produce omega-3 fatty acids on its own, so they must be obtained through diet.

Benefits of Omega-3

  • Heart Health: Reduces the risk of heart disease by lowering blood pressure, reducing triglycerides, and decreasing the risk of arrhythmias.

  • Brain Health: Supports cognitive function and reduces the risk of Alzheimer's disease and other dementias.

  • Inflammation: Helps reduce inflammation, which can contribute to chronic diseases.

  • Mental Health: May alleviate symptoms of depression and anxiety.

  • Eye Health: Essential for maintaining good vision and preventing age-related macular degeneration.
