Key Points

  • Vitamin D is needed by virtually every cell in the body, and is essential for hundreds of processes each and every day. It acts as a protector and regulator of all cell types, tissues, and organs, it is able to enhance the functioning of each system of the body to help keep us healthy. A deficit in vitamin D can lead to impairment or disease in each of these systems – from brittle bones to heart disease, cancer and dementia.
  • Omega-3 fatty acids, such as DHA and EPA, are essential to our health. Higher omega-3s have been associated with improved cognitive function and cardiovascular health, lower risk of dementia, lower risk of cancer, longer life, and a reduced relative risk for death from any cause, including COVID-19. They are beneficial for normal vision, anti-aging, skin health, maternal health, immune system, brain health, heart health, normal liver function, joints and muscles, and more.
  • Use the following infographics to share evidence-based information about vitamin D and omega-3s, and other nutrients, for better health

Vitamin D and omega-3 fatty acids can both influence many aspects of our health.  Yet, nearly 90% of US adults are not getting enough vitamin D to have the recommended vitamin D level of 40-60 ng/ml (100-150 nmol/L).

In terms of omega-3 fatty acids, the typical diet for most individuals, up to 80-90% in some countries, does not provide enough omega-3s EPA and DHA to provide the known health benefits associated with a higher omega-3 status.

It is important to know your levels of both!
