anti-litigation hat on.. I'm not a doctor yet
but midwife definitely try krill oil. In fact, I think I shall remind myself to buy some krill oil, I'm sure everyone could benefit at a low dose regularly. I bought some for someone once, quite a few years ago, cost loads but think was only just being made available at that time.
izzy I would say... go with the supplements you think are of the higher quality possibly not the holland&barrett ones though please HB dont sue me
I think with most of these things, cold processing is good (preserves as much of the good stuff..) and not using nasty gases and things in the processing of the supplement.
In terms of dosage I reckon it's probably pretty safe- unless you are pregnant (vitamin A) or have any bleeding disorders, or take any other drugs that can affect coagulation, because it can inhibit platelet aggregation.
It directly affects the liver and arachidonic acid (among many other things) but aa is used in the formation of prostaglandins, and leucotriene and thromboxanes.. it inhibits the COXetc enzyme pathways before they've begun, if you like, and how aspiring works as an antiinflammatory is directly on the COX enzyme, so it's a very advance pre-anti inflammatory..
and does loadsa other great things too
So I think anything between 1 and 3g a day would be safe
I doubt you'd see an enormous benefit in upping to 3g, maybe go middle of the road and have 1.5g a day for a time, then down it to 1g..
I only say this because there have been studies in long term fish oil supplementation that show high doses (sort of 2,3g a day) can be harmful- if we take krill oil to be a far superior fish oil, it could be that it could potentially cause some of the same effects as having too much fish oil supplementation. Obvs the body has to process and metabolise excesses of anything we take in.. and of course all these benefits really depend on co-actions in the body anyway, coenzymes and other substances and also our baseline diet
Krill oil benefits are reported at low doses such as 300g. while krill oil is probably very very safe, much more so than regular supplementation, I'd still say probably stick to 1-1.5g
when I can't sleep later, I might research carbon valencies in krill oil and come up with some marvellous reason why a certain dosage is just right because of how many bonds it can make and therefore how easily it could cause oxidative damage, and so on and so forth.. or I could google it.. but have to get a train now, don't want to go all the way to paddington (it's snowing, and I am very late)
