Cod liver oil

Cod liver oil is another great supplement, but some simply can’t adjust to the taste. However, you’ll never know unless you try, so if you’re not a fish fan, you might want to consider taking cod liver oil. First, it’s a great source of vitamin D, as you get as much as 450 IU per teaspoon, which equals 56% of the DV.

In fact, many doctors used it to treat vitamin D deficiency, and it also has a rich history of being used against rickets, psoriasis, and tuberculosis. Another great thing about cod liver oil is that it contains rich amounts of vitamin A, with 150% of the daily recommended value in only one teaspoon.

However, be careful: taking vitamin A in higher quantities could be toxic. The safest upper limit of vitamin A is 3,000 mcg, and only one teaspoon of cod liver oil has 1,350 mcg of vitamin A. Be careful not to exceed the upper limit of vitamin A!

Another great reason why you should take cod liver oil is that it has plenty of omega-3 fatty acids, which are great when it comes to reducing inflammation in the body and protecting your heart health. Besides fatty fish, cod liver oil is another wonderful source of these fatty acids.
