Anvisa, Brazil's National Health Surveillance Agency, has announced the suspension and recall of two dietary supplements produced by Santo Mato Farma LTDA, specifically Calm Days and Libi Now. The agency's decision affects all batches of these products, which are sold in capsule form. The suspension was enacted because the supplements were manufactured and distributed without the necessary stability studies, which are essential for confirming that the product maintains its safety, composition, and quality throughout its shelf life.
