Look at the ingredients first. Many brands of lactoferrin on the market have only the word lactoferrin in their names. What else does the name contain? Or TM logo, in fact, just applied for a registered trademark or is submitting an application, and then look at the ingredients list, there is no lactoferrin component at all. Or some products are labeled with whey protein, but whey protein is not pure added lactoferrin, and only contains 0. 1%-0.3% lactoferrin. In fact, the lactoferrin that children drink can be said to be minimal. Therefore, it depends on the ingredient list and the ingredient list clearly marked with lactoferrin, and the product name should be formulated with lactoferrin.
