Flax seed oil is a much tastier alternative to fish oil, in my opinion! Rob and I joke sometimes when we drink it, "ooh, a mild, nutty flavor", so says the bottle! Really, it isn't that bad at all. Pure liquid is much cheaper than capsules. Mix it in with smoothies and you will never know the difference. It is very heart healthy, too, as it helps to keeps fats moving in the bloodstream, so they can't stop and take up house in your arteries! There is also research that it can help lose weight, as an anti-fat. I haven't read too much about that, though. A couple of Tbs a day will keep you moving! We call it Flaxative in our house.
Oh, about the Vitamin C...be careful what you mix it with. I take Alpha Lipoic Acid. It is one of the most powerful antioxidants on the market these days, and it is supposed to help with insulin resistance. It is also a Vitamin C and E recycler, so I don't know if that could cause damage or not! I don't know if there are any other recyclers on the shelves or not.
