I have been loyally using your Kidney Support for years and my numbers have remained the same. I stopped ordering late in 2025 when the price went up to $47.00 a bottle, quite an increase. I did reorder recently when a 30% discount was offored although I only ordered 2 bottles. With deep discounts I will order again but not at $47.00 a bottle.

Thank you for sharing this, Ray. We appreciate your long-time trust in Quantum Kidney Support and are glad it’s been consistent for you over the years. We understand the price can be a factor, so it’s great you were able to take advantage of the 30% promotion. That’s often the best time to stock up.
