Neurio-good for children who are lactose intolerant to diary products. https://neurio.com.au/#content-1, page-13

Oh my god... Lactoferrin contains no lactose because it is not lactose, it is a protein. Saying lactoferrin contains no lactose is like saying that oil contains no water. Lactose intolerance is caused by the lack of lactase enzyme to digest lactose, which is a disaccharide found naturally occuring in milk. Lactoferrin will not help anyone who are lactose intolerant if the milk itself, not the lactoferrin, but the milk itself, still contain the naturally occuring milk sugar. So saying that lactoferrin would help with lactose intolerance is absolutely not true. So stop. Lactoferrin and lactose intolerance is a separate thing.
