California Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, requires businesses to warn consumers if their products contain harmful levels of chemicals, including heavy metals, known to cause cancer, birth defects, or reproductive harm. It is the strictest regulation in the U.S. currently applied to baby food, setting rigorous daily allowable limits of consumption for heavy metals naturally found in the earth in order to protect health.

'mcg' is short for micrograms. One microgram is one-millionth of a gram. Micrograms are often used to measure tiny amounts of substances, like vitamins, medications, or contaminants in food and water. For reference, Cerebelly pouches have a net weight of 113 grams, which is equivalent to 113 million micrograms.

'ppb' stands for parts per billion. One part per billion means one unit of a substance per billion units of the total, often used to measure extremely small concentrations in substances like air, water, or food. For perspective, one ppb is equivalent to about one drop of water in an Olympic-sized swimming pool. This level of precision helps monitor trace elements, including contaminants or nutrients, to ensure safety and quality standards.

A 'lot' is a batch of product produced. Lot numbers are unique identifiers assigned to specific batches during the manufacturing or packaging process. They help track and trace items from production to sale. Lot numbers are essential for traceability, quality control, inventory management, and regulatory compliance. Lot numbers are typically printed on product packaging to ensure product safety and quality throughout the supply chain.

'non-detect' is used to indicate that the analytical results fall below the Limit of Quantification (LOQ) used in testing. When test results indicate 'non-detect' it does not mean that there is absolutely zero present. It means that it cannot be quantitatively measured or identified within the sample because the amount present is below the sensitivity threshold used in testing. LOQs represent the lowest concentration that something can be quantitatively measured with acceptable precision and accuracy. For instance, if an LOQ testing threshold measures the presence of an element up to a sensitivity level of 6 parts-per-billion, than a level of 3 parts-per-billion would show up as 'non-detect' in that analysis because it wouldn’t be able to be confirmed or measured with acceptable precision and accuracy.
