Should I worry about Vitamin A levels in your Cod Liver Oil?
There is some concern that cod liver oil has high levels of vitamin A. This concern stems from the fact that almost all cod liver oil products on the market are supplemented with added vitamin A (natural or synthetic). This is because many cod liver oil products are not made from cod livers! Many brands use fish body oil from species such as pollock or haddock as a less expensive source of oil, and then add vitamin A and D to mimic cod liver oil. This practice is allowed because the international production of cod liver oil is regulated by only one rule—the final product must match the specific EPA ratio (EPA to DHA) found in cod liver oil. These practices are not applicable, however, to the Nordic Naturals brand, and never have been. We have always used 100% Arctic Cod Livers in our CLO formulas, which have consequently always had low, healthy levels of naturally-occurring, fat-soluble vitamin A. We have never used fish body oils or any synthetic additives of any kind in our CLO. Nordic Naturals CLO typically averages 650-1500 IU of vitamin A per serving, which falls in the low range compared to other manufacturers’ products that can contain more than 4500 IU. The recommended daily allowance of vitamin A for adults (as established by the US Institute of Medicine of the National Academy of Science) is 3,000 IU for men and 2,300 IU for women.http://www.nordicnaturals.com/en/Gen...ublic/FAQs/264
That's really interesting. I hadn't heard it.. can't you just read the label (ingredients) ... I mean if it says "cod liver oil" on it, compared to pollock, haddock, etc. then you'd know. It would be helpful to list the brands that are deceptive in this manner, so people would know which to avoid.
If you have any other info about this, or other links, I'd like to read them (esp. any links not
from the site trying to sell its own product of course. Every company seems to have its say on why their
product is always the best.)
The one I used prior to pregnancy and during was TwinLab I purchased at local health food store.. I didn't research it or anything, I just found it locally because it was convenient. After birth I switched to Carlsons which I ordered online because Twinlab used to come in glass bottle and changed to plastic and I didn't like that. Carlsons comes in a colored glass bottle, its also refrigerated, and I've been using it since.. it had a lot of good reviews from people online. I have never tried Nordic - I noticed the container is purple is it glass or plastic, and does it come (and are you supposed to store) refrigerated?
I never would have imagined there would be brands of "cod liver oil" that actually contained other
fish oils (no cod livers) with added vit. A and D. I do read labels pretty good, but that is just plain strange.
