Spatone is a low dose iron supplement and research has shown that people with high iron stores will absorb little iron from Spatone. Spatone is thus a safe, effective iron supplement which provides iron for those requiring it, but should not cause iron overload in those with adequate iron stores.
In order to cause acute iron toxicity in young children it is probable that the content of over 50 Spatone sachets would need to be drunk at once. Poisoning from excessive consumption is therefore unlikely.
You can safely take up to three sachets during the last trimester of your pregnancy to keep your iron levels topped up.
