To ensure I get enough Vitamin A and D, I take a Halibut Liver Oil capsule daily.
Halibut liver oil contains more vitamin A and more vitamin D per unit weight than any other common food.
In addition, it contains 7 percent each of the essential omega-3 fatty acids EPA and DHA, and small amounts of vitamin K.
Cod liver oil works about the same, but with halibut liver oil, the capsules are smaller, and you don't get any aftertaste.
The fat-soluble vitamins in fish liver oils are best absorbed with a meal that contains fat. Absorption of vitamin A, D and K is inhibited by some medications including antibiotics, antacids, steroids, laxatives, mineral oil and some cholesterol lowering medications.
