“My six-year-old son used to be agitated and hyperactive. He was losing hair on the back of his head, had night sweats, and would chew his hands. All these symptoms were due to a lack of calcium, but calcium supplements had no effect. Then a friend recommended Amkey's calcium supplement - Pearl Strength Plus. After one week, my son was sleeping better and no longer suffered from night sweats. He also stopped chewing his hands and clothes, and is no longer hyperactive. I am really thankful for Amkey's products.”
