The Globe and Mail reports in its Thursday edition that there's nothing like mother's milk. The Globe's Hannah Alper writes that for years, infant formula makers have tried to replicate its health benefits. A Canadian entrepreneur may have brought them closer. Toronto native Laura Katz, 34, is the founder of Helaina, a New York-based start-up whose mission is to create, scale and commercialize lactoferrin, an immune-supporting protein found in human milk. Now, after seven years of building her company, Ms. Katz's moment has arrived. Last month, Nestle announced a multiyear partnership with Helaina to buy the ingredient and work together to advance infant nutrition. Helaina's mandate is to "bring human bioactive proteins to every baby and adult in the world," Ms. Katz said. Lactoferrin helps support immune function, iron metabolism and the gut. Supplemental versions of the protein until now came from cows, whose milk produces one-10th of the amount of lactoferrin found in human breast milk. Using a process called precision fermentation, Helaina creates lactoferrin proteins "bioidentical" to those found in breast milk. The company has for the first time made this kind of lactoferrin available at commercial scale.
