Johnyvee, thanks for a great contribution.

You mentioned krill oil instead of cod liver, and it sounds like you have put some investigation into that.

Wondering if you have an opinion on the skate liver oil by these guys:
http://www.greenpasture.org/public/Produ...eLiverOil/

I`m not familiar with that producer specifically, but in general I would recommend krill oil over fish oil, provided it`s from Antarctic krill, meets international fishing standards and hexane has not been used in the extraction of the krill oil. Basically avoid the cheapest supplements! I also like to break one capsule open and smell the content, or smell the fish oil. If it`s too rancid, I`m sceptical of taking it. You can`t do that with products that have lemon oil etc etc to mask any smell. The Astaxanthin in krill oil should protect it from lipid oxidation.
I`m to lazy to write down all the reasons for krill oil being superior at the moment, but I agree with the following points from Dr. Mercola`s site listed below.
https://articles.mercola.com/sites/artic...h-oil.aspx

Higher potency

Studies have shown that krill oil may be 48 times more potent than fish oil. This means you need far less of it than fish oil, as confirmed by a 2011 study published in the journal Lipids.1
Researchers gave subjects less than 63 percent as much krill-based EPA/DHA as the fish oil group, yet both groups showed equivalent blood levels — meaning the krill was more potent.

Contains phospholipids

Fatty acids are water soluble, but they can't be transported in their free form in your blood — they require "packaging" into lipoprotein vehicles. In krill oil, the omega-3 fat is attached to phospholipids, which means your body can readily absorb it.
In fish oil, the omega-3s are attached to triglycerides that must be broken down in your gut to its base fatty acids of DHA and EPA. About 80 to 85 percent is simply eliminated in your intestine. Studies confirm krill oil is absorbed 10 to 15 times better than fish oil.
It's also able to efficiently cross your blood-brain barrier to reach important brain structures.
Phospholipids are also one of the principal compounds in high-density lipoproteins (HDL), which you want more of, and by allowing your cells to maintain structural integrity, phospholipids help your cells function properly.

Contains phosphatidylcholine

When you consume fish oil, your liver has to attach it to phosphatidylcholine in order for it to be utilized by your body. Krill oil already contains phosphatidylcholine, which is another reason for its superior bioavailability.
Phosphatidylcholine is composed partly of choline, the precursor for the vital neurotransmitter acetylcholine, which sends nerve signals to your brain, and for trimethylglycine, which protects your liver.
Choline is important to brain development, learning and memory. In fact, choline plays a vital role in fetal and infant brain development, so it's particularly important if you are pregnant or nursing.

Resists oxidation

Fish oil is quite prone to oxidation, and oxidation leads to the formation of free radicals. Consuming free radicals further increases your need for antioxidants.
Fish oil is very low in antioxidants whereas krill oil contains astaxanthin — probably the most potent antioxidant in nature — which is why krill oil is so stable and resistant to oxidation.
(According to industry expert Rudi Moerck, Ph.D. the vast majority of fish oil being sold is actually rancid before you even open the bottle, because it doesn't have this protective antioxidant.)
Independent Oxygen Radical Absorbance Capacity (ORAC) evaluations have established that krill oil (courtesy of the astaxanthin) has over 300 times the antioxidant power of vitamin A and vitamin E; 47 times that of lutein; over 34 times the antioxidant power of CoQ10.

Contaminant-free

Fish are very prone to mercury and other heavy metal contamination, courtesy of widespread water pollution. Antarctic krill is not prone to this contamination.
Not only are they harvested from cleaner waters, but since krill is at the bottom of the food chain, it feeds on phytoplankton and not over other contaminated fish.

Environmentally sustainable

Krill is far more sustainable than fish because it's the largest biomass in the world, making krill harvesting one of the most sustainable practices on the planet. Harvesting of krill is also carefully regulated, and only 1 to 2 percent of the total krill biomass is harvested each year.
The krill population is monitored by The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). The Marine Stewardship Council (MSC) certifies that harvesting is done in compliance with strict sustainability criteria to avoid overfishing.
