Not sure why lanolin wouldn't be OK with you.. by: Kerri Knox, RN- The Immune Queen!
So, as far as I know there is no difference and I think that you are simply 'overthinking' it a bit. If you think about how humans get our vitamin d, we get the oil on our skin irradiated and it absorbs through the skin.
That is the same way that sheep get theirs and that is all that the lanolin is- irradiated oil from the skin of the sheep. One of the reasons that dogs lick themselves and monkeys groom each other is to ingest the Vitamin D that was created on the fur from sunlight.
The Vitamin D from lanolin is bioidentical to what we make from the sun- as is fish. I wouldn't worry about where it comes from as long as it's D3...

Supplement Purity and Safety by: Lauren M.P.
Thanks for your comments.
I'm pregnant and have been taking 7000 mg of vitamin D3 a day, at the advice of my midwife-nurse practitioner. I have been D-deficient, having levels of half of what they should be, thus the high dose. I know there's controversy surrounding dosage and amounts of D, but after doing some reading I decided to trust the midwife that the gains are worth this high dose (and that it is not dangerous.)
What I'm actually concerned about now is purity. I've been taking cod-liver oil derived gel capsules of the Bluebonnet brand. When I recently realized that the D vitamin I'm taking is derived from cod-liver oil, I became concerned, since COD is known to be one of the (big) fish that is relatively high in mercury (and presumably this concentrates in the fish fat?) I'm concerned also with PCBs. The fetus is getting an extremely high dose, concentrated and potent, of whatever is in these capsules every day-- including any heavy metals and possibly toxic derivatives from the 'cleansing' process (I was alerted to this possibility by more website reading). Perhaps taking this many pills a day is just too much of a risk? I've included below my note a quote from a scientific paper that indicates that 'purification' from fish oil eliminates some percentage of the PCB and mercury, but certainly not all of it.
I would certainly appreciate your thoughts!
Also, I wonder if there is a benefit to choosing Lanolin-derived D to avoid the fish-contamination concerns. . . or are there independent concerns with large mammals?
Many thanks, Lauren
?Five types of oil derived from various Baltic fish were purified. Reduction in the PCDD/Fs content was 77.0-93.6% on average, whereas in the dioxin-like polychlorinated biphenyls (dl-PCBs)-it was 42.7-50.5% on average, with insignificant changes in the total amount of EPA and DHA content. Furthermore, a significant reduction in the content of arsenic was noted (by about 62% on average), with insignificant changes in the content of organochlorine pesticides (OCPs), and marker polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), cadmium, lead, and mercury. Purification provided fish oil having standardized parameters that allow for its use as feed additives, whilst retaining its favorable fatty acid content.?

Many Concerns by: Kerri Knox, RN- The Immune Queen!
Hi Lauren,
First of all, your concern about the 'high dosage' is unfounded. If you were deficient before and you are pregnant, you may not even be taking enough to relieve your deficiency! 7000 IU's is about the 50,000 IU's per week 'standard' dose given to anyone with deficiency, but some people, depending upon the severity of their deficiency, could need up to 3 times that dose to relieve their deficiency!
So, not saying that you need more, just saying that your characterization of 7000 IU's as a 'high dose' is incorrect. And if you take a look at the chart on my Vitamin D and Breastfeeding page, women need to take 6400 IU's per day to even meet their baby's minimum needs during breastfeeding.
So, I would say that 7000 IU's is merely a maintenance dose for the average pregnant or breastfeeding woman. But be sure to get regular levels to make sure what YOUR particular needs are and that they are being met appropriately.
Next, I have no thoughts on fish oil derived Vitamin D. If you are concerned, the only possible way to know whether yours are contaminated or not is to call the manufacturer and ask for an independent testing report.
I only use lanolin based supplements and have had ZERO problems despite having clients who have INTENSE sensitivities and problems with heavy metals. And 99% of all Vitamin D supplements on the market are from lanolin. You have to try very hard to find one from fish.
Another option is an Vitamin D3 From Algae, the only vegan supplement that I can recommend.
The ONLY real problems that I get are people who take oil based supplements and have a reaction to the oil that has gone rancid. Therefore I ONLY recommend 'dry' or no oil supplements.
The other problem that people have is when they become magnesium depleted from the vitamin d. These two problems cause 99% of the problems that I see from vitamin d and being pregnant, you should be particularly concerned about magnesium deficiency as that is the MAIN reason that women get toxemia of pregnancy (preclampsia and eclampsia).
So, do please read my page on Magnesium and Vitamin D to see why the magnesium issue is so important...
Keep it up. Seems like you're on the right track..

Thank you, Kerri, for your detailed and careful response to all my questions about dosing/purity of D-supplements and thanks, particularly, for alerting me that I should be taking magnesium!
