Chanca piedra, a small Amazonian herb whose name translates to "stone breaker," has been used in South American herbal tradition for centuries to support kidney and urinary tract wellness.* Stonexyl builds its formula around a clinically studied 450 mg dose of chanca piedra and adds Crataeva nurvala, a traditional Ayurvedic herb, along with nutrients and BioPerine for absorption.

What's inside

• 450 mg chanca piedra, standardized 4:1 extract, the amount used in clinical studies
• Crataeva nurvala, traditionally used to support healthy urinary flow*
• Nutrients that are often low when kidney wellness is a concern*
• BioPerine black pepper extract to support bioavailability
• Non-GMO, vegan, third-party tested, made in a GMP-certified facility in the USA, 180 capsules

How to use

Take as directed on the label with plenty of water. One bottle of 180 capsules provides a three-month supply. Anyone with a diagnosed kidney condition or taking prescription medication should speak with their doctor before use.*

Why we carry it

Chanca piedra products vary wildly in potency, and many give no dose at all. Stonexyl states a 450 mg standardized dose, matches it to the research, and backs it with third-party testing. The three-month bottle also means customers can stay consistent without reordering, which matters for a supplement meant to be taken over time.*
