Future food firm Soylent has issued a total recall on its food bars after reports that they were giving some consumers upset stomachs.
The food bars, launched last month and designed to give 12.5 per cent of the total nutrients needed for a day, have now been withdrawn from sale and the company is offering a full refund.
"A small number of our customers have experienced gastrointestinal issues after consuming Soylent Bars," the company said in a statement.
"As a precautionary measure, we are halting all Soylent Bar purchases and shipments and are advising our customers to discard any remaining bars in their possession. We are deeply sorry if any customer had any negative experiences after eating a Soylent Bar."
