Magnesium Taurate vs. Kids Calm

[worriedmommy]

I've read a lot of posts saying that Magnesium Taurate is more effective for tics than Kids Calm. My dd (6) has been taking Kids Calm since Feb, and honestly I didn't think it was doing any good. I stopped it about a week ago, and since then I've noticed a definite increase in irritability and tics. So, I am putting her back on it. My question is whether it would be better to have her on Magnesium Taurate? If so, does anyone have any advice on what brand & dosage? She is 6, weighs 49 lbs and does not swallow pills.
