Alkali Citrate Science


Alkali citrate helps prevent kidney stones.  

Anyone who’s suffered from a kidney stone knows that they don’t ever want another one. Alkali citrate for kidney stones is key to preventing this painful condition, although there are some pervasive myths about how it works and where to find it.

Not all citrates are the same. While many claim that drinking alkali citrate-rich lemon juice and water will help prevent stones, the citrate that you can get from citric acid (such as lemon juice, citrus fruit, etc.) actually isn’t enough to prevent the formation of kidney stones. In fact, you’d have to drink several quarts of lemonade per day to get the right amount of citrus citrate to be preventive. Moreover, citrus fruits are relatively low in pH and don’t support healthy kidney chemistry. Alkali citrate, however, is the powerful component that is known to prevent kidney stone formation along with other key nutrients and ingredients.


The science of alkali citrate & Moonstone. 

Alkali citrate helps prevent kidney stone formation by reducing the ability of calcium in the urine to bind with oxalate. Specifically formulated by kidney stone specialists—including nephrologists and urologists—Stone Stopper by Moonstone™ contains clinically significant amounts of alkali citrate that increases urine citrate and urine pH in the body. This works because increased urine citrate helps prevent calcium stones, while increased urine pH helps dissolve and prevent uric acid stones and cystine stones. *1 Although citrate from lemon juice and citrus beverages may raise urine citrate, these drinks are missing the other key nutrients that help prevent stone formation. For citrate to enter the urine and act to prevent kidney stones, it must be ingested accompanied by sodium, potassium, or magnesium—and this is exactly what Stone Stopper by Moonstone™ provides. Ultimately, lemon juice and other beverages cannot realistically supply what the body needs to prevent kidney stones. Stone Stopper by Moonstone™’s higher net citrate content provides more “net base”, also known as alkali, which is essential to preventing kidney stone formation. **2


Painful stones can affect anyone.

Nephrologist and internationally recognized kidney stone expert David Goldfarb MD—a founder of Stone Stopper by Moonstone™—can relate to the unbearable pain of passing kidney stones, because he’s had three of his own. Dr. Goldfarb had his first stone in his late 20s, and he remembers it as if it were yesterday. “I was walking down the street, and I was suddenly struck by this tremendous pain. It felt like a large chef’s knife had been stuck in my back,” Dr. Goldfarb says. “And I was doubled over, soaked through my clothes sweating.” A dramatic day in the ER followed. But once the stone passed, Dr. Goldfarb says that he—like most people—forgot about it. Very few people take steps to prevent a repeat attack, but most kidney stone sufferers will form another stone within 5-10 years. 

“Most people who pass relatively small stones in the emergency room—as I did—typically don’t follow a healthy diet and don’t drink enough water,” Dr. Goldfarb says. “And that’s why kidney stones are so prevalent.” After his second attack, Dr. Goldfarb, who is now the director of a leading kidney stone clinic, began researching how to prevent stone formation using a natural approach. He wanted to find a preventive solution without relying on distasteful horse-sized prescription pills, a restrictive diet that’s difficult for people to follow, or drinking gallons of water or lemonade per day. With an expert team of doctors and health care professionals coming together, Stone Stopper by Moonstone™ was formulated.
