Obviously n=1 does not a study make but I take a very high dose of vitamin A with FCLO (10ml) and shellfish, liver, etc. (I also take butter oil and a vitamin k2 supplement) My vitamin D levels consistently run between 65-75. When I drop the FCLO the only thing that happens is I start getting keratosis pilaris bumps on my skin... no matter how many colorful veggies I eat. I just really don't think this is a huge deal in people who are eating like we do. Many of the people on these forums who are reporting their blood tests are annually to bi-annually getting blood tests and are seeing good or at least rising levels of D. The average joe on the street is D deficient, mineral deficient, DHA deficient, etc.

I really don't understand the controversy.

Have you read all of the WAPF positions on Vitamin A, D, and K2? Especially Chris Masterjohn's articles?

(EDIT: removed comment regarding the quote at end of your posting - thought it was written by you)

So far I read one link by a group of doctors that likely think saturated fat is bad for us as well.

I will respond more once I can actually read the studies referred to in that ONE article you have posted.

EDIT:

part way through reading, here is an excerpt from the study that shows red flags over how you are interpreting it. In short, people were asked if they had smoked X cigs any time of their life, but only whether they took supplements in the past 30 days was considered. Furthermore, they DID NOT MEASURE dietary vitamin A intake, only supplemental. Which, by the way, we would guess that most supplemental forms are via B-Carotene...

Participants were asked whether they had smoked at least 100 cigarettes in life and whether they smoked currently to identify current and former smokers. For those who had smoked at least 100 cigarettes, number of cigarettes smoked per day, years of smoking habit, and years of quitting smoking were further queried. ... Participants were asked whether they had taken any vitamins or minerals in the past month and labels of supplements in the household were recorded. Those who took any forms of vitamin A and/or b-carotene supplements were identified as vitamin A/bcarotene supplement users. Dietary intake data for vitaminA were not used in this analysis because the single 24-h recall method used in NHANES III is unable to provide accurate estimates of usual dietary vitamin A intake due to its high day-to-day variability

it seems to me that the A to D ratio is important.
but know one really knows what it should be, either in the diet or in the body.
(& whether D means all the "D's" or just D3?).

Paul Jaminet suggests in his book that the maximum healthy ratio of A to D (from all sources; sun, food, supps) is no more than 3 IU to 1 IU.

Now, it would also seem that quite a few people on Paleo Hacks supplement with Vitamin D.
So as an example if we estimate someone's total Vitamin D intake as 4,000 IU per day, that would mean they could (safely?) intake up to 12,000 IU Vitamin A per day.

Also note that this is 12,000 IU of the animal form of Vitamin A (retinol) which equals 4 mg retinol.
It will equate to more than 4 mg in non-animal forms, ie. using the Linus Pauling Institute as a reference;
4 mg Vitamin A Retinol equates to;
.... 8 mg supplemental beta-carotene, or
.... 48 mg dietary beta-carotene, or
.... 96 mg dietary alpha-carotene, or
.... 96 mg dietary beta-cryptoxanthin

Another piece of info i read at vitamindcouncil is that "Vitamin A protects against vitamin D toxicity and visa versa but we don't know why".

My n=1: The lower left corner of my lip was dry/chapped/flaking all through the winter and spring, but it cleared up when I went on a two week trip without my supplements. I reintroduced supplements one at a time, and I found that when I reintroduced the Fermented Cod Liver Oil, my lower left lip swiftly became dry/chapped/flaky again, clearing up once more a few days after stopping the FCLO. I was taking the FCLO with butter oil and Vitamin D, but I'm persuaded that for me, my regular diet appears to have sufficient Vitamin A and the FCLO supplementary Vitamin A is harmful. If anyone has any possible accounting of the science behind this, however, I'm all ears--I can't figure it out.

Nobody in modern society is getting TOO much Vitamin A.

It just doesn't happen. It's like omega-3s. Nobody is getting too many omega-3s.

And I don't believe for a second that beta carotene can correct any sort of Vit A deficiency. Beta carotene is pretty useless as a source of Vitamin A and BC itself functions more as a plant antioxidant than animalform retinol. In addition, high serum levels of Vit A =/= adequate levels of Vitamin A in the body.
