    Carlson Norweigian Cod Liver Oil is a rich source of omega-3 fatty acids, which support heart health, promote optimal cholesterol levels, and enhance mental health through its ability to help protect against dementia and other age-related cognitive problems, and it targets depression, inattentiveness, and hyperactivity [1, 2]. Cod liver oil also an excellent source of vitamin D, which supports optimal mental performance, enhances immune system function, strengthens muscles and bones, helps protect skin cells from UV damage, and has anti-cancer properties [3-8]. Furthermore, cod liver oil supports healthy blood sugar levels and targets inflammation [8, 9]. It also contains vitamin A that promotes wound healing [8-10]. Cod fish usually contains more vitamin E than other warm water fish and this particular vitamin boosts the immune system and overall health [11].

    Overall health [1-10]; Enhanced immune system, heart, brain, skin, bone, muscle health [1-11]
    Cod liver oil contains large amounts of omega-3 fatty acids, which are healthy triglycerides that help lower unhealthy triglyceride and LDL (bad) cholesterol levels [1]. The omega-3 fatty acids in cod liver oil also contain cannabinoids that have anti-inflammatory properties [10]. The vitamin A in cod liver oil appears to accelerate the epithelial (tissue-related) and vascular (e.g., blood flow) components of the healing process, thereby improving wound healing [8-10]. Furthermore, cod liver oil contains docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) which protects cells in the brain from different types of damage, including tissue damage that can lead to dementia or other age-related cognitive issues, due to their antioxidant, vasodilating, anti-inflammatory, and anti-arrhythmic properties [2]. Cod liver oil is a good source of vitamin E and it supports skin, vision, cardiovascular, cognitive, and joint health, as well as the immune system [11].
