Soylent is a nutritional drink, intended to cover all human nutritional requirements for an adult so that it may serve as main or sole food. Its creator, software engineer Rob Rhinehart, researched nutritional requirements and developed the formula by self-experimentation based on his own research online, with textbooks, and through scientific journals.[1][2]

A commercial version of Soylent has been financed by a crowdfunding campaign on Tilt and venture capital which raised funds in excess of US$3,500,000.[3][4] The funding paid for additional research and modification of the formula. The first shipments of U.S. orders began in the first week of May 2014.[5] In January 2015, Soylent received $20 million in Series A round funding, led by Andreessen Horowitz.[6]


As of May 2013, Soylent had been tested by Rhinehart himself and by a handful of volunteers as well as individuals recreating the substance independently at home.[2][7] Modifications to the ingredient list have occurred. Though versions of the product could be made at home using non-typical food items, Soylent manufactured by the Soylent company utilizes ingredients generally recognized as safe[8] by the United States FDA.

Version Changes Date
Soylent 1.0 First full version. Ingredients were finalized in January 2014[9], and shipments began in April[10](vegan) and May[11] (regular) of 2014. Early 2014
Soylent 1.1 The sucralose was decreased, giving it a more neutral flavor, and it added new digestive enzymes.[12] October 2, 2014[13]
Soylent 1.2 Omega-3 from fish sources was replaced with omega-3 from algae, making the drink suitable for vegans and the enzymes added in Soylent 1.1 were removed.[14] November 10, 2014[15]
Soylent 1.3 Dipotassium phosphate was added and shipping box sizes were reduced.[16] December 11, 2014[17]
Soylent 1.4 Fats were incorporated into the powder which eliminated the need for the oil bottles, resulting in less packaging required in the shipping boxes and isomaltulose was added.[18] February 25, 2015[19]


The product's name is an inside joke based on Harry Harrison's 1966 science fiction novel Make Room! Make Room! in which the food product derives from soya and lentils. Although it's commonly associated with its 1973 film adaptation Soylent Green in which the eponymous food supplement is made from human remains.[20]


In April 2013, Rhinehart said he was spending US$154.62 per month on Soylent, yielding a diet of 11,000 kilojoules (2,600 kcal) per day[21] while a diet of medical food such as Jevity would cost US$456 per month for 8,400 kilojoules (2,000 kcal).[22] For comparison, a family of four in the United States can purchase enough food to eat at home for approximately US$584 per month[23] which is slightly less per person than Rhinehart's base Soylent cost.

Soylent 1.0, shipped commercially since May 2014, was supplied in quantities of 7, 14, or 28 bags, with 7 bags stated to be enough for "21+" meals.[24] As of February 2015 it was available only in the US, at $85 for 7 bags, reducing the price for larger quantities or a monthly subscription.[25][26]

Reviews on the taste of Soylent vary widely. Negative reviews have called it a "punishingly boring, joyless product", "like someone wrung out a dishtowel into a glass ",[32] "purposefully bland", "and compared the taste to "homemade nontoxic Play-Doh".[33][34] Others were "pleasantly surprised" with the "rich, creamy, and strangely satisfying" flavor,[34] or likened it to that of a vanilla milkshake with the texture of pancake batter.[35]
