The makers of<unk> claim it contains the nutrients necessary for a healthy lifestyle. Some people have experienced gastrointestinal problems from consumption of<unk>  particularly flatulence. Lead and cadmium content On August 13, 2015, As You Sow filed a notice of intent to pursue a lawsuit against the makers of<unk>  claiming that<unk> was in breach of California's Proposition 65 for not adequately labelling its product given the levels of lead and cadmium present in the drink. Although<unk> contains levels of lead and cadmium far below the national safety levels set by the FDA, it does contain 12 to 25 times the level of lead and 4 times the level of cadmium permitted in California without additional labeling. A lawyer who has worked on settlements of Proposition 65 suits described the case as "alarmist", as the levels are well below FDA limits of what is allowed in food products. However, as<unk> is marketed as a complete meal replacement, many customers consume the drinks three times a day, equating to 36 to 75 times the lead and 12 times the level of cadmium without the Prop 65 label.<unk> s website displays the Proposition 65 warning required by California.<unk> Nutrition, Inc. published the position that the levels of heavy metal content in<unk> "are in no way toxic, and<unk> remains completely safe and nutritious".<unk> Nutrition, Inc. also published an infographic and spreadsheet based on an FDA study of heavy metal content in common foods, comparing two selected example meals to servings of<unk> with a similar amount of caloric intake. Both of the company's chosen comparison meals include high levels of cadmium and arsenic, along with levels of lead similar to those of<unk>  although one of them includes tuna and the other includes salmon, providing over 97% of the arsenic in each proposed meal, with spinach providing 74% of the cadmium in the higher-cadmium meal and fruit cocktail providing 71% of the lead in the higher-lead meal. Product recalls In 2016, the company announced it would halt sales of the<unk> Bar due to reports of gastrointestinal illness, including nausea, vomiting, and diarrhea. The company asked customers to discard any unconsumed bars and said it would offer full refunds. On October 21, 2016, the company triggered a product recall. On October 27, 2016, the company also halted sales of<unk> Powder. The company said tests on the bar had not shown contamination but also said that some powder users had reported stomach-related symptoms from consuming the powder. The company initially suspected soy or sucralose intolerance. However, on November 7, 2016,<unk> instead blamed algal flour for making people sick and said it planned to remove algal flour from future formulations of the powders and bars, which it did in the next formulation version 1.7 introduced on December 15, 2016. The drink-based products use algal oil, not algal flour, so were deemed to be safe for users.
