It's been a tough few weeks for Soylent. After recalling its new food bars for giving customers vomiting and diarrhea, the startup ended up pulling its famous meal-substitute powder from shelves as well. The company said a handful of powder customers were reporting similar gastrointestinal issues to those causes by the bars. The problem was affecting less than 0.1 percent of all customers, but the complaints were obviously severe enough to halt all sales of two of the company's four product lines.
At the time, Soylent noted that its tests came back negative for food pathogens, toxins or outside contamination, and also said that it only affected the most recent iteration of its powder. "This possible connection allows us to narrow the field considerably given there are only a few ingredients that are specific to only our bars and Powder 1.6," it said. Well, the culprit has been found: algae.
