Heavy metals are naturally occurring metals in the environment with high density (hence 'heavy'). Plant-based products bear heavy metals in plants that come from the soil. Else products are monitored for heavy metals to ensure the level is within the allowed levels for food. Our product is also certified as Clean Label (check out our certification!), and, as part of the Clean Label’s Purity Award certification process, all heavy metals levels were analyzed and confirmed to be below the maximal allowed levels in baby food.
