AAP Increases Vitamin D Recommendation

We take Green Pastures' high vitamin cod liver oil (CLO) daily. We each get about 5750IU (115% adult RDA) of vitamin A and 575IU (140% adult RDA) of vitamin D in our morning's 1/2 teaspoon. Soon we will start taking a fermented CLO which will provide a similar amount of vitamins in about 1/4 teaspoon. This CLO is closer to traditional fish/fish liver "supplements."
Upon looking back at the Weston A. Price Associations recommendations, I think I will increase my dosage. Hmm...glad I looked at that just now.

You may have seen my fridge post with the rotting fish - I mean fermented fish sauce. I've still not filtered or tried it. This is what people from Rome to Thailand used as a salty condiment (and still do all over Asia). Norsemen had barrels of fermented cod livers to eat from.
The American Academy of Pediatrics has even realized the importance of plenty of vitamin D and increased the recommendation for babies and children to 400IU (from 200IU).

Vitamin D helps build strong bones through the regulation of calcium absorption and use. It works synergistically with vitamin A, and consuming the the two vitamins in a 1:10 (D:A) ratio seems to prevent the body from absorbing or storing too much of these fat-soluble vitamins.

It should also be noted that the FDA allows many substances to be labeled as the same vitamin that are not really the same: The form of vitamin A that our bodies uses is retinol; this is the form found in CLO and other animal foods including liver. Beta-carotene is often label as vitamin A in foods and supplements, but only about 25% of the beta-carotene we eat is converted to retinol which the body can use - and that's on a good day. You see, the body needs fats to convert beta-carotene to retinol, so it is important to consume things like carrots and greens with fat such as cream, butter, or lard. Too much beta-carotene can be toxic.
We make vitamin D when we are exposed to UVB rays from the sun, but most of us don't spend much time in the sun, and when we do, we often cover up and worse yet - slather ourselves with sunscreen (which is made of toxic chemicals) to block the sun's rays, and "synthetic D₂ has been linked to hyperactivity, coronary heart disease and other allergic reactions." -WAPF

So, it may taste a little fishy, but it's well worth the effort.
