Ensure is the brand name of a family of liquid nutritional supplements manufactured by Abbott Laboratories.[1] The beverages are meant to be administered orally, or through nasogastric tubes, directly to the recipient's stomach.
Recipients are either individuals unable to eat or experiencing undesirable weight loss, through age, infirmity or disease, or individuals like captives who are on a hunger strike, who are undergoing involuntary force-feeding.
Hunger strikers at the Guantanamo Bay detention camps are force-fed Ensure via gavage.[2][3][4]
In 2009 Abbott Laboratories sold over $1 billion of its liquid nutritional supplements, Ensure, and the related pediatric product, PediaSure.[1]
