Olympian Labs is one of my preferred companies. This krill oil has very good specifications. Good ratio between DHA, EPA and Astaxanthin. I take two softgels per day: one in the morning and one in the evening. Krill oil is never cheap and this one is not an exception. That's why I often buy California Gold Nutrition's oil, which is a better deal. When it is on sale, I buy this one.
I have taken this & Source Naturals brand Krill Oil. The Krill oil itself comes from the same company in Canada (Neptune) but who cares, buy from the manufacturers you like. For me, I "perceive" a difference in eye health; sounds strange, but that's what it seems like. I wear glasses and was on the verge of 'upping' the prescription on it, but now I don't think there will be a need for that.
