Hi. I m hoping you can help me. I just bought from a Naturopath here in New Zealand a product called Colo2 zone. It s a dietary supplement of Magnesium Oxides (= Magnesium as a propietary blend of Magnesium Oxide and Magnesium hydroxide). I was given it for my 34-month-old grandson who has been experiencing chronic constipation for around 2-3 months (going only once every 5-6 days and even that only with the help of Movicol, twice daily). I really wanted to get him something that was more natural and could be used for a reasonably long period and then weaned off. The Naturopath assured me that 1/4 - 1/2 teaspoon of this would do the trick, with the added benefit of improving the muscle tone in his rectum, and he assured me that it was safe in that dosage to give to a child that young. But I ve come across a website that says it shouldn t be given to a child under 6 years old because it hasn t been tested in children that young for safety and effectiveness. I really want to help my grandson but I d hate to introduce him to something that might be harmful to him. Do you have an opinion on this please?
