Cod liver oil has traditionally been consumed as part of the diet, in particular, by people living in northern coastal areas of Norway. It was crucial to survival, especially the cold, dark and stormy conditions. Northern Europeans used cod liver oil to protect them from the cold. It was also said to relieve such complaints as rheumatism, aching joints, and stiff muscles. At the beginning of the 20th century, scientists established that cod liver oil was antirachitic, and so mothers would give it to their children. Modern scientific studies lend credence to the historical views.

It turns out cod liver oil is a nutrient-rich wholefood. Unadulterated cod liver oil is a time-honored source of vitamins A, D3, and long-chain omega-3 fatty acids, especially docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). The dose of vitamin A in cod liver oil is moderate and the quality of vitamin A is excellent. Vitamin A is essential for bone growth, night vision, cellular growth, health of the endothelial cells (cells lining the body’s interior surface), regulation of cell growth and division, testicular and ovarian function, and immune system health (by stimulating the production and activity of white blood cells). Vitamin D is a unique nutrient that acts as a hormone with a range of physiological functions. It exerts its activity by binding to cellular vitamin D receptors. Cells of the immune system, especially those of the intestine, have abundant vitamin D receptors. Vitamin D therefore has an impact on the immune system, playing an important role in regulating the immune system. It also plays important roles in bone health, mineral homeostasis, cell growth, muscle function, nervous system function, skin function, control of the renin-angiotensin system, control of insulin secretion, regulation of apoptosis, and controlling infections. High doses of vitamin D monotherapy needs precaution for potential adverse effects and should be substituted with a natural source of vitamin D in combination with synergistic vitamin A and omega-3 fatty acids, such as cod liver oil.

DHA and EPA are particularly important nutritional components. While most “traditional” omega-3 sources on the market contain little DHA, Rosita’s EVCLO contains a high proportion of DHA and excellent levels of EPA. Both DHA and EPA are concentrated in the phospholipids of cell membranes throughout the human body, but especially in the grey matter of the brain, heart, retina, and testes. These fatty acids have also been shown to have hypo-lipidemic, anti-inflammatory, anti-thrombotic, vasodilatory, and anti-arrhythmic properties.
