The Real Reason Why You Should Take Cod Liver Oil

Learn about the amazing benefits of cod liver oil, a superfood rich in omega-3 fatty acids, vitamin A, and vitamin D.

In this video, we’re going to talk about the health benefits of cod liver oil. Cod liver oil is an excellent source of omega-3 fatty acids, EPA and DHA. EPA has potent anti-inflammatory properties, while DHA supports cognitive function. Cod liver oil is also rich in vitamin A and vitamin D.

Don’t confuse cod liver oil with fish oil! You would need 12,000 mg of fish oil to equal just one tablespoon of cod liver oil.

You can not get vitamin A from fruits and vegetables. Beta-carotene is only a precursor to vitamin A, not the active form. Cod liver oil contains retinol, the active form of vitamin A.

The most common autoimmune disease is Hashimoto’s hypothyroidism. There’s a significant link between vitamin A deficiency and hypothyroidism.

There are vitamin A receptors inside of your white blood cells, so it’s crucial for immunity! Vitamin A also helps to regulate iodine.

Vitamin A supports the mucus membranes of your mouth, sinuses, throat, and lungs, so it’s critical in preventing infections. It also supports the roots of the microvilli on the inside of your intestinal tract.

Vitamin A supports the health of your retina. If you’re deficient in retinol (the active form of vitamin A), you can go blind.

Cod liver oil is also a good source of vitamin D. Without vitamin D, you can't pull calcium and magnesium into the body.

Beans, legumes, grains, and cereals are very high in phytic acid, which increases the need for vitamin D. If your diet is high in these foods, it’s easy to become deficient in vitamin D.

      @@denisemaples6519 Cod liver oil is high in EPA and DHA omega-3 fatty acids, vitamins A and D, and some vitamin E.

      Krill oil contains EPA and DHA omega-3s, phospholipids, and the antioxidant astaxanthin, but lacks the vitamins A and D found in cod liver oil.

      I think the omega-3 in krill oil is more easily absorbed by the body. Also krill oil is supposed to be less likely contaminated by mercury.

    00:00 🎣 Cod liver oil is a superfood rich in omega-3 (EPA, DHA). Omega-6 from seed oils competes with omega-3 absorption.
    00:54 🌞 Cod liver oil is a valuable source of vitamin D and A, surpassing benefits of fish, sardines, or salmon oil.
    01:47 🦷 Grass-fed butter with cod liver oil is recommended for skeletal development, especially in children and pregnant women.
    02:31 🐟 Cod liver oil is preferable over algae for omega-3, providing essential vitamins A and D, vital for children. Fruits/vegetables don’t offer true vitamin A.
    03:37 👁 Vitamin A deficiency links to autoimmune diseases. Vitamin A regulates iodine, supports mucous membranes, preventing infections.
    04:30 🌿 Cod liver oil, an excellent source of vitamin A, crucial for retinal health, is a preferable alternative for those who dislike liver.
    04:57 💪 Vitamin D in cod liver oil is essential for calcium/magnesium absorption, crucial for diets high in phytic acid.
    05:26 🚑 Cod liver oil is a superfood, combining active forms of vitamin D, A, and omega-3 fatty acids, benefiting the immune system and reducing inflammation.

I tried to show empathy for his veganism and even donated hundreds of dollars to help motivate him towards true learning of the importance of animal protein, but I got shunned. 😐 He even went so far as to hate on Dr. Berg for teaching us true health! 😂 Well, around March 9th of that year, I had enough and put my full focus on Healthy Keto, and I feel so much better! Much appreciated. Have a wonderful day, everyone! 🙂

      I would also recommend cutting out whole milks/whole diary products (lactose dense products). Long story short, to a certain extent EVERY adult is lactose intolerant. I thought just cuz I didn’t get cramps I was just fine. Little did I know that breaking lactose is very demanding of the human body and can cause brain fog.
