I bought Floradix Liquid Calcium-Magnesium w/ Zinc for my 8 year old ADHD boy. He loves it. After taking this, I can see some improvement in his behavior. Of course, not this one alone, he's also taking Liquid Fish Oil, Liquid Vitamin B6 and zinc.
I purchased this product for my 4 year old son with hyperactivity as part of his supplemental routine. He is very particular about tastes and textures, so I was unsure how he would respond. He loved it - especially the "juicy taste" and I had no problem getting him to take it! The only reason I gave it a less than "loved it" rating was the cost.
