You can use oil instead of capsules, which might be better anyways. Capsules might have a longer shelf life but you cannot tell if is is bad inless you break some open to check. Dose is usually alot lower in a capsule so you would have to take quite a few more depending on brand, which is not cheaper in long run. Tho not all oils are equal that is forsure. You can get a lemon or different flavour to mask the fishy tatse and with little to no after taste if you find that a problem. And always always look for a brand that actually publishes independant lab testing, and check it! Sometimes this info is available on the website for certain brands. I agree about the Krill Oil.

Here is a pretty good link of what you should look for when selecting an oil for omegas it is pretty informative...
