"Cerebelly" is a brand of pre-made baby food that differentiates itself by offering 16 key brain-supporting nutrients to aid a baby's growth in the critical first three years of life. It was founded by neurosurgeon Teresa Purzner, who also holds a PhD in Developmental Neurobiology. The brand's food is tested for over 400 contaminants like heavy metals, chemicals, plastics, pesticides, and other toxins. However, it's worth noting that there are mixed reviews about the brand. Some customers have expressed dissatisfaction with their purchases, and there have been several complaints lodged against the company. As with any product, it's recommended to do thorough research and consider multiple sources of information before making a decision.
