A few weeks after she started taking a supplement she bought on TikTok, Tamara Bundy woke up feeling awful. She had bought moringa capsules from a brand called Rosabella after the influencers on her feed claimed they would help with inflammation, bloating, weight loss, and “overall wellbeing,” she says. But suddenly she was bedridden and vomiting with cramps so bad they felt like labor pains. Bundy assumed it must have been something she ate — until she saw someone post on TikTok that Rosabella moringa capsules had been recalled owing to possible salmonella contamination and wondered whether her daily vitamin habit could be to blame.
