We use clinoptilolite zeolite, a naturally occurring volcanic mineral that's been used in water filtration for decades, at a gentle daily amount (50mg per serving), not a high "cleanse protocol" dose. The bigger thing parents should know: raw zeolite mined from the ground can carry contaminants, which is exactly why every Zoyava batch is third-party tested for heavy metals, microbials, and potency before it ships (we'll email you the Certificate of Analysis if you ask). It's made in a GMP certified, FDA registered facility and formulated in the USA. As with any new supplement, if your child has a medical condition or takes medication, check with your pediatrician first.
