I have used these cod liver oil softgels for years and have always liked them. The Vitamin Shoppe also has excellent customer service, and quickly replaced an order that had been lost in shipping without any hassle.

You should not take modern cod liver oil unless you at least are taking high doses of vitamin D. This product contains 2000 IUs of vitamin A but ONLY 250 IUs of vitamin D and this is a problem.

[According to the life extension website]: A study published in year 2004 showed that cod liver oil and a multivitamin slightly reduced mean number of respiratory infections in children, but the total number of doctor visits for these infections was slightly higher in the cod liver oil/multivitamin group (68 versus 61). The 1930s study demonstrated far superior benefits with cod liver oil.

One difference between these studies is that cod liver oil in the 1930s study had more vitamin D. The other issue is that children in the 2004 study received 3,500 IU of preformed vitamin A (not beta-carotene) and only 700 IU of vitamin D.

Given what we now know, a more appropriate dose should have been 500-1,000 IU of vitamin A (instead of 3,500 IU used in the 2004 study) and 2,000-3,000 IU of vitamin D3 (as opposed to 700 IU used in the 2004 study).
Excess Vitamin A Can Thwart Vitamin D

Vitamins A and D compete for each other's function in the body. Preformed vitamin A, found in excess amount in many commercial supplements, can thwart vitamin D's protective effects. This is not an issue with beta-carotene, as it converts to vitamin A in the body only on demand.

Consumption of excess preformed vitamin A, as found in commercial multivitamins and modern cod liver oil, may cause bone toxicity in those with inadequate vitamin D status. One study showed that women with the highest intake of preformed vitamin A had 2.1 times more hip fractures. A meta-analysis found that people who took preformed vitamin A supplements had a 16% increase in overall mortality, perhaps through antagonism of vitamin D.
