A dairyman from New Jersey, a government laboratory and a packet of powder.

Lactaid is an American brand of lactose-free milk and dairy foods, sold alongside lactase dietary supplements. Its story begins with a dairy family. The brand’s own website, in a version archived in January 2026, says Lactaid was founded by Alan E. Kligerman, a third-generation dairyman who got his start delivering milk to customers in Atlantic City. The company says he studied dairy science at Cornell and founded the brand in 1974.

The technical side of the story runs through a government laboratory. In the US Department of Agriculture’s 1992 Yearbook of Agriculture, published as New Crops, New Uses, New Markets, the chemist Virginia H. Holsinger of the Eastern Regional Research Center of the Agricultural Research Service in Philadelphia wrote a chapter called “The Lactaid Story”. It describes how her team tested the lactase enzymes then available and treated pasteurized milk with an enzyme taken from a yeast, finding that the main change in flavour was a sweeter taste.

A New Jersey company picked up the work. Holsinger’s chapter says the SugarLo Company of Pleasantville, New Jersey, which she calls the progenitor of Lactaid Inc., contacted the research service after the laboratory published its results in October 1974. SugarLo obtained an exclusive licence for a yeast lactase made by Gist-Brocades of Delft, in the Netherlands, and filed a petition for the enzyme to be affirmed as Generally Recognized as Safe, which the chapter says was granted.

The product reached shoppers in a do-it-yourself form. According to the USDA chapter, SugarLo sold the enzyme in single-dose packets of powder, which a customer stirred into a quart of milk and left in the refrigerator. The powder was phased out in 1981 in favour of a sterile liquid that the chapter describes as much easier to use.

Wikipedia’s article on the dairy company HP Hood, citing The Wall Street Journal of 20 April 1993, says Kligerman introduced the Lactaid brand of lactase supplements in 1977, and, citing The New York Times of 5 May 1982, that he began to license the brand to dairies in 1982. The Lemelson-MIT Program, in its profile of Holsinger, says her research formed the basis of Kligerman’s Lactaid milk and supplements business, which launched in the mid-1980s.

SugarLo, Lactaid Inc., McNeil, HP Hood and Kenvue.

The liquid enzyme made ready-treated milk possible, Holsinger’s chapter says, and it explains the factory method: in a milk processing plant the sterile lactase was added to milk that had already been pasteurized, held for a day, pasteurized again and then packaged for retail sale. By the time of the 1992 yearbook, she wrote, the treated milk was sold as nonfat, lowfat, chocolate and calcium-fortified milk, and Lactaid Inc. had also developed cottage cheese and a pasteurized process American cheese. The company began marketing lactase capsules to health professionals in 1985, the chapter says, and later sold tablets made with lactase from the fungus Aspergillus oryzae.

A dairy took the milk to market. Wikipedia’s HP Hood article, citing the trade magazine New England Business of February 1987, says Hood brought Lactaid-branded milk to the New England market in 1984.

The brand then moved to Johnson & Johnson. Wikipedia’s HP Hood article, citing The Wall Street Journal of April 1993, says that in early 1991 Kligerman licensed the Lactaid brand to McNeil, a subsidiary of Johnson & Johnson. The Lemelson-MIT Program says Johnson & Johnson bought Lactaid Inc. in 1991 and that the brand went on to operate as a unit of J&J’s McNeil Nutritionals division.

Production stayed with Hood. The same Wikipedia article, citing the trade magazine Dairy Foods of December 2001, says Hood became the official supplier of Lactaid milk for the East Coast in 1991 under McNeil’s supervision, and that in 2001 it renegotiated its contract with McNeil to supply Lactaid milk for the whole United States.

Johnson & Johnson later separated its consumer business. Wikipedia’s article on Kenvue says the new consumer health company took that name in September 2022, held its initial public offering in May 2023 and completed its separation from Johnson & Johnson in July 2023. Kenvue has owned the Lactaid brand since that separation; the Lactaid website, as archived in January 2026, is published by Kenvue Brands LLC of Fort Washington, Pennsylvania, and Wikipedia lists McNeil Nutritionals, part of Kenvue, as the business that markets Lactaid.

A further change was announced in 2025. The Associated Press, in a report carried by WRAL on 3 November 2025, said Kimberly-Clark had agreed to buy Kenvue in a cash-and-stock deal that still needed the approval of both companies’ shareholders. Tissue Online North America reported on 6 October 2026 that the purchase remained on track to close in the fourth quarter of 2026, subject to regulatory approvals.

Design and documentation.

Eggs and fluid milk are among the plainest things in a grocery basket, and that plainness shapes how their packaging works. An egg carton has to protect a fragile product, stack in a chilled case and still tell a shopper at a glance what kind of eggs sit inside, so its lid, its colour and the words printed on it do most of the brand’s work. A milk jug or carton has a similar job: it has to be recognised quickly on a crowded shelf, often by a cap colour or a band of type, before anyone reads the small print.

Because the products inside can look alike from one name to the next, the brands in this group lean on labels, logos, carton shapes and advertising to set themselves apart. Some of the names belong to farmer-owned cooperatives, some to family companies and some to much larger food groups, and the name on the front does not always say which.

Each guide separates what independent sources record from what the company says about itself — its founding story, its owners over time, where its eggs or milk are packed and how its packaging has changed — and marks plainly what rests only on the company’s own word.

LactAid, Lactaid, LACTAID and a three-part promise on the carton.

The name itself has changed shape. Wikipedia’s article on McNeil Consumer Healthcare says Kligerman originally called his lactase supplement “LactAid”, with a capital A in the middle, and notes that the capitalisation changed to Lactaid when the brand was licensed to McNeil in 1991. The same article, citing The Wall Street Journal of April 1993, says Johnson & Johnson spent heavily on new packaging and advertising for the brand during the 1990s.

On its own website the brand now sets its name in capital letters. The Lactaid site, in its January 2026 archived version, writes the name as LACTAID® throughout, and its home page carries the line “Real Milk. Real Delicious. Lactose-Free.” The site’s about page uses the headings “We Take Our Milk Seriously” and “Real Milk, No Lactose”, and describes the product as real dairy milk in which a lactase enzyme breaks down the lactose.

The range has grown well beyond the carton of milk that Holsinger described in 1992. The archived website lists milk, ice cream, cottage cheese and sour cream among its products, along with creamers, eggnog and the lactase supplements that started the business. Wikipedia’s HP Hood article lists Lactaid as a brand of McNeil Nutritionals that Hood produces.

The brand’s founding story is also part of its presentation. The about page tells the account of Kligerman as a third-generation dairyman on a milk route in Atlantic City and gives 1974 as the founding year, the same year that, according to Holsinger’s USDA chapter, the Eastern Regional Research Center published the enzyme results that brought SugarLo to its door. The Lemelson-MIT Program describes the result as a transfer of government research into Kligerman’s business, and Holsinger’s own chapter closes by crediting the exchange of information between the research service and Lactaid Inc. for a range of lactose-modified dairy foods.

For a design guide, Lactaid shows how a grocery brand can carry a scientific process in plain, friendly packaging language, with a capitalised name and a short three-part line doing the work. Compare Tylenol, another McNeil brand now owned by Kenvue, and Fairlife, another American milk brand. For this guide we use dairy blue, deep navy, sky and milk white with a rounded sans, an unofficial interpretation; no product or logo is reproduced.
