Product naming
The real name of lactoferrin products is usually "xx brand lactoferrin mixed milk powder", such as "witsbb lactoferrin mixed milk powder". And those who are called "xx brand lactoferrin solid drinks" are probably scratching their edges, not real lactoferrin.
Trademark trap
Some merchants will deliberately play with trademarks, such as applying for the trademark of "XX Milk Iron" and then naming the product "XX Milk Iron? Protein powder "or" XX milk iron R standard protein powder ". It sounds tall, but it may actually be just ordinary protein powder.
national standard
Real lactoferrin products must be marked with "GB 14880-20 12 National Food Safety Standards for the Use of Edible Nutritional Fortifiers". This standard stipulates how much lactoferrin should be contained per 100mg, which is the key to judge whether lactoferrin is true or false.
