Does anyone worry about...

[~Quse~]

the fact that CLO is heated to extremely high temperatures to get out the heavy metals and toxins?

[xenabyte]

I actually avoid CLO anyway, but ICK! If that's 'standard proceedure' for all CLOs, then they are highly toxic to your system...might be lead/mercury free, but it would be full of free radicals formed from the high heat treatment....

I'd definitely check individual processing for each company to be sure!

I just take Chia Seeds, as they are vegan, no contaminants and supply the same thing, plus are in a 'natural state' and are a 'whole food' complex that is synergistically complete and easily absorbed...

There are updates on the WAPF site. They recommend very few brands of CLO now.

But even Blue Ice is subjected to 180 degree celsius heat.

nordic naturals

we use nordic naturals clo, and if my research serves me correctly, it is a great source, not only price wise, but in terms of distillation, etc....anyone hear otherwise?

[bigknitwit]

bumping this thread - this is bothering me and I'm curious as to what other people think about it.

[cobluegirl]

Oh Jane!!!!!!

[Gale Force]

So are there any chemists here who know how oil is molecularly distilled?

We use Nordic Naturals as well.

Here is a link to an interview with Nordic Naturals that may shed some light on this...

We use a molecular distillation process for our cod liver oil, but we keep the integrity of the oil and the naturally occurring levels of EPA -- which is the eicosapentaenoic acid that helps with inflammation -- and the DHA -- which is the docosahexaenoic acid that helps nervous system, brain health and synaptic firing. At their natural levels, they will be the most effective. However, molecular distillation does do something to the levels of vitamins A and D.

Basically, we lose about 50 percent of the vitamin D in the distillation process and about 5 percent of the vitamin A. That doesn't sound like much, but what you are assuring is the amount of vitamin A and D in our cod liver oil only occurs in the fish. We don't augment it with synthetic vitamins A or D. What you are getting in one teaspoon of our cod liver oil is the highest level you would see in any cod liver oil of DHA and EPA. It is 700 milligrams of DHA. It is 450 milligrams of EPA, and the vitamin D ranges anywhere from around 10 to 40 IU, which doesn't necessarily come up to your 100 percent level of intake, but it does affect brain health and mood. The vitamin A can range anywhere from about 990 IU to 1,950 IU. This comes close to 40 percent of a recommended daily allowance.

We do have a process that utilizes steam. If you're talking about our fish oil products, we are using cod and anchovies. These anchovies are saltier, which can lead to a fish odor, but we do use some processes that are unique. We filter the oil in a way that removes particulate matter, and we use a stripping steam process that is all-natural with no chemicals, to help eliminate odor. The only vitamins we're adding are the naturally-occurring vitamin E and in some cases ascorbic acid, vitamin C and rosemary extract, which is a natural stabilizer. This ensures our product a three-year shelf life.

I would assume that if the EPA and DHA remain that this process is not a high heat molecular distillation. Not sure if I am correct or not. I have always found this company to be superior in their process to any other. In the second quote he talks about the steam process to reduce odor that only applies to fish oil not he CLO.

Wlderness Family Naturals' CLO (which they are currently out of) does not sound like it is heated..."Our Cod Liver Oil is produced from cod that is caught in the cold, northern waters off of Norway. This oil has never been hydrolyzed, fractionated or molecularly distilled. It is simply a natural cod liver oil, purified by filtering through diatomaceous earth. This oil is independently tested to ensure the absence of detectable levels of mercury and other heavy metals, PAH’s, PCB’s and dioxins."

Because it isn't distilled, it isn't high vitamin like Blue Ice, but it sounds like great quality to me.

[elelvee]

Why would distillation give it high vitamins? I think high vitamins comes from the separation of the oil. The high vitamin is the heavier oil in the lower part of the barrel, and vice versa.

[kbchavez]

I could be wrong, but I thought the distillation process made the oil more concentrated than naturally occurring oil... even the richer heavier oil that sinks to the bottom of the barrel. But I may be making an assumption that's wrong... anyone have any information? I should go read that article on CLO production that is on the WAP website.

[kbchavez]

Well, here's a quote from the CLO article at WAP:

"The deodorization step is a new technology and replaces molecular distillation that many mills formerly used to fully clean the oil.

In molecular distillation, the oil is heated under a vacuum to about 190oC by direct heat on a hot surface. The volatile compounds are distilled from the oil.

The newer deodorization process heats the oil to 170-180oC by flushing steam through it. The steam removes the volatile compounds and carries them out. As the heat is indirect and the temperature lower than distillation, there is less likelihood of damage to the polyunsaturated fatty acids. The new deodorization process is more efficient in removing compounds that impart flavor and odor to the oil--which is why the process is called "deodorization." This, according to the industry, is a real advantage because "the oil is of better sensoric quality than before."

To summarize, the benefits of deodorizing (compared to molecular distillation) include a lower peroxide value, better flavor and odor, and a cleaner product. The disadvantages include a much lower natural vitamin A content and virtually no vitamin D."

So I was wrong about distillation making it high vitamin... it's about the smell apparently. The author goes on to say that he doesn't think it's necessary to deodorize at all and that Garden of Life doesn't. And Wilderness Family naturals doesn't either. So for those of you concerned about the heat, these would seem like good (though not quite as good tasting) options.

[kbchavez]

I forgot to add this part...

The high vitamin oil has natural vitamins added back in after the deodorization process. It isn't the heavy oil from the bottom of the barrel (or if it is, it still loses a lot of vitamins in the deodorization process that need to be added back in afterwards).
