Horlicks is a sweet malted milk hot drink powder developed by founders James and William Horlick. It was first sold as "Horlick's Infant and Invalids Food", soon adding "aged and travellers" to their label. In the early 20th century, it was sold as a powdered meal replacement drink mix.
It was then marketed as a nutritional supplement and manufactured by GlaxoSmithKline (Consumer Healthcare) in Australia, Bangladesh, Hong Kong, India, Jamaica, Malaysia, New Zealand, South Africa, Sri Lanka, and the United Kingdom. It was previously in Kenya in the 2010s but was discontinued due to low sales. It is now produced by the Anglo-Dutch company Unilever through its Indian division. Horlicks in the UK is currently owned by Aimia Foods.
On 3 December 2018, Unilever announced they were buying Horlicks Indian business for US$3.8 billion. The Horlicks UK business had already been sold in 2017 to Aimia Foods, a UK-based subsidiary of Cott Corporation.
In Britain, Horlicks is commonly consumed as a drink near bedtime, and is marketed as an evening drink; in contrast, it has been marketed as a breakfast drink in India.
