I've recently upped my krill-oil dosage to 4 capsules a day and was astonished to find that my irises are lightening up at a far more rapid rate than before(previously , I experienced some amount of iris-lightening in the first 3 years, with the effect happening at a very, very slow rate in the last 5 years of doing this diet).Anyway, has anyone else noticed iris-lightening as a result of taking krill oil or blue ice cod liver oil? It does seem possible that, even though I've been on a raw diet for so long, that I needed still more omega-3s than is usually available in raw foods.

Are there any raw varieties of this remarkable product available on the market?
What brand do you use or recommend?

I thought that Fermented CLO would be the best Omega-3 supplement. From this article (http://kellythekitchenkop.com/2009/09/dave-wetzel-fermented-cod-liver-oil.html) it seems that Dave Wetzel is not a huge fan of Krill oil and he obviously knows something about fish oils:
What About Fish and Krill Oils?
Fish oil and krill oil, sold as supplements to provide omega-3 fatty acids, are by-products of the fish and krill meal industries. They are produced in large factories humming with the noise of conveyer belts, grinders, separators, extractors and dryers. We provide two descriptions of fish oil manufacture and one of krill oil manufacture, and let our readers decide whether or not they want to consume these products. Remember that omega-3 fatty acids are very fragile and highly subject to damage when exposed to heat and oxygen.
KRILL OIL MANUFACTURE: Frozen Antarctic krill are crushed and the lipids and proteins are extracted using acetone. Following extraction, the krill proteins and lipids are filtered through an organic solvent-resistant filter under reduced pressure to enable physical separation of lipids and proteins. Excess acetone is evaporated and water is separated from the oil. The oil is subjected to additional filtration and purification to remove impurities and is packaged in a modified nitrogen-containing atmosphere and stored. The notifier provides product specifications for krill oil, including specifications for fatty acids, total phospholipids, esterified astaxanthin, saturated fatty acids, and trans-fat (<0.1 percent). Specifications also include limits on residual acetone (<10 milligrams per kilogram (mg/kg), lead (<0.1 mg/kg), mercury (<0.1 mg/kg), arsenic (<0.1 mg/kg), cadmium (<0.1 mg/kg), pesticides, and microbiological contaminants”

I tried the fermented stuff, hated it.
"because it is a lacto-fermented product, it can leave a slight sting on the back of the throat, which some find bothersome." I eat a little lacto-fermented cabbage every week, it never leaves a sting.
Slight sting my arse. How about a corrosive burning sensation, like a stop only worse, and taste even worse than the foul stuff that was forced on me in childhood.
I find it really hard to believe that tough guys like Vikings and Roman soldiers would insist on this stuff.

Tyler, you seem to be monitoring the shade quite often. Do you check in the mirror every day or make pictures?
If would be interesting to keep a track record with an album of pics taken under similar lightening conditions.
On a side note: I noticed my grandparents changed their eyes to blue in their late years. I know this because I have a early color picture with them and the eyes were much darker.

Isn't that stuff messing with whales?

We use the Blue Ice raw fermented cod liver oil. It tastes disgusting, I won't lie. We chase it with food, so I don't know if it burns.
We use 1 teaspoon of the cod liver oil most days.
I haven't noticed a change in our eye color. Perhaps I wouldn't notice even if it did occur.
What I have noticed is that my family has golden skin color compared to just about everyone else I see. Other peoples' skin seems to be very pinkish red to me. Until I changed our diets I didn't really pay attention to these kinds of indications of health. Now I think that other people's skin looks inflamed and mottled (poor perfusion) compared to my family. We have good skin strength in the sun (tanning, not burning), and our skin tone is of an even color. I think this is due to the vitamin A (beta carotene) of the cod liver oil, as well as having better nutrition in general.

was astonished to find that my irises are lightening up at a far more rapid rate than before
lucky guy you are... iris color would be absolutely the last thing I would worry about. i'd be very happy to be in optimal health with irises of any color.

OK, so far we seem to have identified raw eggs, raw adrenals and krill oil as foods that lighten the irises. What are the common denominators? I think eggs and adrenals both have cysteine and eggs and krill oil both have A and D3.

i'm confused... wasn't there a recent thread on omega-3 intake and nose bleeds?... or is that only above some optimal level?

My father in law wants to know if iris-lightening is a good thing or a bad thing.

I suspect that it's good sign, because it appears to come from high levels of nutrients, but I don't know if it produces any real health benefits.

My understanding is that the Mercola krill oil product is cold-extracted, and is reasonably high-quality.

My camera isn't working right now and I'm too lazy to get it fixed(besides, I presume I would need additional special lighting). I do check in the mirror every day which is why I was astonished to find such a rapid change.

I doubt there are any common denominators. I'm sure that a darkened iris might be due to multiple health-issues with the darkened colour merely a side-effect. That is, my irises darkened further when I consumed any raw/pasteurised dairy but I don't think that raw dairy directly caused a reduction in omega-3 levels, for example.
-

Well, as I understand it, krill are in huge numbers in the oceans and whales are in such small numbers(due unfortunately to human predation) that it's not an issue.
-

Well, I noticed something surprising. Even though I'm taking 4 (1g?)capsules of krill oil a day, a recent cut on my forefinger stopped bleeding remarkably quickly. Perhaps it requires 10g or more for nosebleeds to occur.
-
My father in law wants to know if iris-lightening is a good thing or a bad thing.
Well, I can only go by my own experience.As I gradually discovered that raw dairy was harmful to me, I'd noticed that my irises had become slightly lighter in shade on the edges in the first couple of months of rawpalaeo, and that they had become much darker when I started consuming raw dairy. Similiarly, my iris-colour lightened as I increased in health in the first 3 years of the diet(though, admittedly, until recently the change was very minimal). So, I think it does have some bearing on health, but not necessarily 100%.

The level at which excessive bleeding starts seems to vary between individuals.

Tyler, how long did it take for the 4 capsules a day of krill oil to noticeably lighten your irises?

Mercola apparently currently uses an Aker Biomarine krill oil product. Aker reportedly cooks the krill and then extracts the oil with ethanol. The only version of krill oil that reportedly is not cooked and doesn't use ethanol, acetone, or hexane solvent is Cyvex's KriaXanthin, which is sold under the NSI and Meridian brands at Vitacost and Amazon.com, respectively. KriaXanthin also happens to be the cheapest version of krill oil I've seen, which may be due to the fact that they don't process their krill oil as much. The limited processing also means it has very low concentrations of EPA and DHA versus other brands, but it's still cheaper per mg of EPA/DHA.
Mercola's brand is the most expensive I've seen, and I've noticed in general when looking at this products that he tends to charge more for them than other sellers, possibly because of a combination of his small volumes and because he can charge more for the Mercola name.

Aker Biomarine’s Krill Fisheries Receives Marine Stewardship Council Certification http://www.aquapreneur.com/2010/05/26/aker-biomarines-krill-fisheries-receives-marine-stewardship-council-certification/
“The Board notes that the production and manufacturing process of Superba oil presented by the applicant is substantially equivalent with that of the NKO oil’s. Mainly, the methods differ from each other only as regards the extraction of the oil, where Aker Biomarine uses extraction with ethanol from krill meal cooked and dried on the vessel, while NKO oil is extracted with acetone from frozen raw krill.
However the difference in the manufacturing process has no substantial impact on the composition of the end product, i.e. the oil, and both methods are acceptable as regards food safety.” http://www.stockhouse.com/Bullboards/MessageDetail.aspx?s=NTB&t=LIST&m=27746653&l=0&pd=0&r=0

Most interesting. Mercola claimed the krill-oil was cold-extracted, so if the above is correct, I am none too pleased. Thanks for taking the trouble of doing the research involved.
As regards the iris-lightening, that took c. 2 months for it to be really noticeable. Maybe it wasn't all that badly heated?
-
You're welcome. Your results and those reported by Dr. Eades re: krill oil are sufficiently interesting that I decided to give it a try and researched it to see what to buy. Here's what I found on the temperatures Aker uses, though it's second-hand info:
"In some preferred embodiments, freshly caught krill is first subjected to a protein denaturation step. The present invention is not limited to any particular method of protein denaturation. In some embodiments, the denaturation is accomplished by application of chemicals, heat, or combinations thereof. In some embodiments, freshly caught krill is wet pressed to obtain oil and meal. In some embodiments, the meal is then heated to a temperature of about 50° C. to about 100° C. for about 20 minutes to about an hour, preferably about 40 minutes to denature the proteins." http://www.faqs.org/patents/app/20080274203
-
Well, it's an important lesson never to buy from Mercola ever again. I've always loathed the guy.
-
Well, it's possible the info could be wrong, but if you loathe him then there doesn't seem much point in buying from him.
-
do you really think all those 'Doctors' give a crap about our well being? it is all about money. however their good intentions might have been in the beginning, all of it has been replaced by money and more money.
all of them are the same, Mercola, Graham, Campbell, etc., they tell us things we want to hear and sell us things we want to buy.
-
To recap, be careful about krill oil brands where it's claimed that they're "cold-extracted". That doesn't guarantee that the process is a natural one. All but one of the cold-extracted brands that I've seen use "cold-extracted" to mean that toxic solvents like ethanol or acetone are used. For example, acetone is used by Neptune Technologies in their NKO krill oil (see http://www.stockhouse.com/Bullboards/MessageDetail.aspx?s=NTB&t=LIST&m=27746653&l=0&pd=0&r=0 and http://www.efsa.europa.eu/EFSA/efsa_locale-1178620753812_1211902333142.htm) There are even rumors that one or more manufacturers may use hexane.
The only brand I've seen it claimed is processed without solvents or heat is Cyvex's KriaXanthin. KriaXanthin is about half as potent as the most potent brands (and less than half the cost), which makes sense, because the harsh extremes solvent and heat processing are not used to extract every bit of phospholipids. I don't get the sense that the krill oil industry is heavily regulated, so there's no guarantee that the claims about KriaXanthin are true, but at least the claims of natural processing are made.
I just received my first order of KriaXanthin and will give it a try. The equivalent of TD's 4 doses /day of Mercola's brand of Aker krill oil is 7 doses of KriaXanthin. However, I also take raw fermented CLO and vitamin D3, so I think I'll try 4 doses /day of the KriaXanthin for now.
-
7 doses? Ok, I'll get that next time.
*Just looked at 1 of the Kriaxanthin links and saw "75% off" being promoted. Sounds too good to be true! ;)
-
Yeah, my math worked out to 7 KriaXanthin servings (softgels) having about equal doses of omega 3's as 4 of Mercola's Aker krill oil servings. The krill oil industry is fairly new, so I wonder what other bad news we'll learn about it in the future, but your results do intrigue me.
Peter of Hyperlipid has suggested in the past that the vitamin A and D in CLO might reduce the potential for negative side effects from omega 3 overdose via ordinary fish (or presumably krill) oil. Peter didn't have a source at hand at the time, though. I would think that vitamin K2 would also offset some risks like nosebleeds and easy bruising. Have you gotten any such symptoms from your krill oil intake?
-
No, nothing like that - not even when I consumed 8 of the mercola krill-oil tablets a day at one point.
-
I think you stopped taking CLO once you started taking krill oil, yes? My guess all along has been that the concerns of Peat and Peskin about omega 3's are way overblown (one clue is that the foods they recommend instead of omega-3-rich foods include substandard, non-Paleo, non-raw foods). It doesn't make much sense that a nutrient that was rich in one of the original staple foods of hominins--brains--would be toxic to humans at relatively low doses. I think Peat and Peskin probably haven't thought much about the role of brains in the history of the human diet.
I don't rule out, however, Peter's and KGH's concerns about overdoses of omega 3's potentially causing problems if not offset by vitamins A and D3 and I suspect that nose bleeds are an early indicator of overdosing, as they are the only symptom I've ever gotten from high dose omega 3 intake. Plus, I was eating cooked and carby foods at the time, including nightshades (which Dr. Cordain recently published a 3-part article on the dangers of) and squashes, which I have since learned have negative effects on me. Since going raw Paleo I have been able to consume large quantities of omega 3's without getting the nose bleeds, which used to be mostly limited to my left nostril. So I suspect that either my left nostril had a weakness that has healed or I am less susceptible now to problems from high omega 3 intake--possibly in part because of the CLO I take, as Peter suggested, but possibly also due to the RPD that you and I are eating.
-
Well, I stopped taking the raw clo from Blue Ice around last year, I think. Didn't feel the need as it doesn't have much omega-3s in it.
