I have heard that putting it in a glass of grapejuice or orange juice might mask some of the taste.
I used the Health From The Sun brand "Omega 3 flax oil" and it was very grassy tasting, it was nasty. When it came time to order more, I sprung for the extra $2 per bottle and got the "Liquid Gold" by the same maker. Taking my flax oil is now so much better. Very little taste at all. The difference between the 2 from the same brand was incredible, and well worth the extra $2 IMO. I've never tried the NOW brand, but if tastes like the first one I tried, you'd be very happy with the other one I mentioned.
