Best Cod Liver Oil Supplement: Nordic Naturals vs. Carlson vs. Rosita vs. Garden of Life?

    Cod liver oil contains vitamin A, a vital nutrient for immune system function, cellular growth, eye health, and reproduction. It's also rich in omega-3 fatty acids, which decrease blood clot formation and reduce inflammation in the body. There are many brands of cod liver oil available on the market, such as Nordic Naturals, Carlson, Rosita, and Garden of Life. But which makes the best cod liver oil supplement? We reviewed these four brands to help you find the best cod liver oil.

What is Cod Liver Oil?

Cod liver oil is an incredibly nutritious type of fish oil supplement. It’s very convenient and contains a great combination of omega-3 fatty acids, vitamin A and vitamin D. The exact concentration of nutrients in cod liver oil depends on the species of cod, or Gadus, the oil comes from.

Cod liver was first used in medicine in 1789, to treat rheumatism, followed by rickets in 1824. By the 1930s, it was frequently given to children to help prevent rickets and other conditions caused by vitamin D deficiency.

Other fish oils are extracted from the tissue of deep sea cold water fish, including tuna, trout, mackerel, herring, salmon, and cod. Cod liver oil comes only from the livers of cod. It contains less omega-3 fatty acids than regular fish oils, but more vitamins A and D.
