Omega-3 deficiency is the lack of essential nutrients, EPA and DHA, which are found in every cell in our body. These essential nutrients cannot be made or stored, so we must get them from our diets or through supplementation. The National Institute of Health (NIH) recommends 3-5 servings of fish weekly as a minimum to provide the total body benefits of these healthy fats. Since omega-3s are found in every cell in your body, omega-3 deficiency can impact overall and long-term health in many different ways. Consult with a healthcare professional for more information on omega-3 deficiency.
