Renal physiology changes a great deal in early childhood, and urine biomarker reference ranges are very different for infants, toddlers, kids, and teenagers. Their nutrient needs and recommended daily intake are also quite different.
Because of this, we don’t recommend that any children under age 13 use our test, and we don’t recommend that children age 13 - 18 use our tests without explicit parental consent.
Finally, because nutrient supplementation hasn’t been as well studied in children we recommend against supplements such as Vessel fuel for kiddos. Using Vessel results to help guide dietary nutrient changes through whole foods is often very helpful to promote the wellness of our children.
