We take it straight off the spoon (liquid form). Our favorite is from Kirkman Labs and is flavored lemon/lime. My boys love it (ask for seconds at least so I divide up their doses among their helpings) and even my mom, who is very squeamish about the thought of CLO takes it without a problem.
I take mine off the spoon and chase it with a bit of juice. I think the most important thing is to wash it down completely with some other liquid so it doesn't just sit in the back of your throat. Maybe mix it with the juice. Or yogurt?
We take Green Pasture's unflavored right off the spoon. I chase it with a slice or orange or a bit of OJ, my husband just swallows it, and my 15 month old points at it again as if to say, "More, please!"
My kids and I both take it off a spoon. I pour a glass of apple juice, everyone holds their own little cup, then we drink it off the spoon, and before swallowing drink a sip of apple juice while holding breath and swallow. Can't taste a thing. My 2 and 4 year old love it, they think it's fun lol.
I mix mine with a couple ounces of milk or juice. It doesn't taste bad at all, but I can't stand the smell. Way too fishy. Once I find my big bag of empty capsules I plan to put it in them. That's the only way I can get DD to take it, she runs and hides if I try to give her the liquid. DS will take it in juice or milk, but I have to pinch his nose for him.
