Moonstone is the first patented formula to provide daily support for kidney health. It contains clinically significant amounts of alkali citrate to increase urine citrate levels and pH. It is one of the easiest and most efficient ways to increase your alkali citrate intake, improve hydration and increase urine volumes.

Moonstone should be used by anyone interested in increasing their alkali citrate intake, improving hydration, and increasing urine volumes.

Moonstone tastes like a refreshing, fruit-flavored drink. It is currently available in Lemon Lime, Cranberry Raspberry, Tropical and Wild Berry flavors.

Moonstone works best when taken as part of a daily regimen, which includes healthy eating, proper water intake and exercise. 1-2 servings of Moonstone per day is the suggested daily amount. You could also divide 1 serving into 2 and drink half a serving twice a day.

To promote kidney health, Moonstone should be consumed daily. Your body needs time to reflect the benefits, like exercise. You cannot work out once and see immediate results; there is a level of continuous commitment needed.

Everyone’s body works differently, but in general there are no negative effects associated with alkali citrate.

Moonstone is available over-the-counter (OTC) and does not require a prescription. Any health-related questions or if you are taking medications, please discuss with your physician.

Moonstone was designed by world leaders in kidney stone prevention as well as beverage industry experts. It is produced at FDA-approved facilities using the highest quality controls and quality assurance protocols.

For best effect and hydration, Moonstone’s ready-to-mix powder should be mixed with 16 oz of still or sparkling water.

One indicator that Moonstone is working is increased urine pH. Urine test strips can be used to compare urine pH levels before versus after drinking Moonstone. Your physician can also order checks of your daily urine citrate excretion levels and imaging tests such as x-rays and ultrasound to check for kidney stones.

Urine pH can range from an extremely unhealthy low of 4.5 to a high of 8.5. The average urine pH is about 6.0.  If your urine sample is lower than 6.0, this could indicate an environment conducive to the formation of kidney stones.

Moonstone is formulated with alkali citrates. Studies have demonstrated that alkali citrates help prevent the formation and recurrence of calcium-based kidney stones, uric acid kidney stones, and cystine kidney stones. Alkali citrates can also dissolve uric acid and cystine stones in some circumstances.

Yes, but check with your physician first. Moonstone may be a good alternative if you have trouble tolerating potassium citrate, but it is not intended to be used in conjunction with it. There are people who take both, but we recommend you check with your physician before making changes to your prescription routine.

Moonstone’s unique combination of alkali citrate salts work by increasing urine citrate and pH to levels that help inhibit stone formation. Alkali citrate supplementation has been shown to reduce growth and recurrence of calcium-based stones, uric acid stones, and cystine stones. Alkali citrate binds with calcium, which helps prevent the calcium from binding with other molecules to form kidney stones. Drinking Moonstone also helps you to stay well hydrated, which is essential to good kidney health.

Alkali citrate is closely related to citric acid, but doesn’t have the acid content. That is why it is “alkali” (high pH), the opposite of acid (low pH). Alkali citrate increases urine pH, which is protective of kidney function, in addition to its known beneficial effect on kidney stone prevention. Alkali citrate is important because it binds to calcium, inhibiting calcium oxalate precipitation.

Lemonade and citrus fruits such as oranges, lemons and limes are weak sources of citrate (citric acid). You would have to consume a lot of lemon juice or eat a large amount of citrus fruits to get enough citrate to change urine chemistry. Moonstone contains effective amounts of alkali citrate. The citrate content of most fruits and vegetables contains both alkali citrate and citric acid, however, only alkali citrate will be excreted in the urine and raise urine citrate and pH levels. Moonstone was designed to optimize alkali citrate levels better than fruits, vegetables, or lemonade, in order to maximize kidney health.

One packet of Moonstone contains 30 milliequivalents (mEq) of alkali citrate from citrate salts plus 25 milliequivalents (mEq) of citrate from citric acid.

Moonstone would benefit anyone with a history of kidney stones, or anyone concerned with maintaining kidney health. Moonstone is appropriate for patients who wish to promote kidney health without the use of prescription medications. Moonstone may also be a suitable alternative for patients who have low tolerance for/low compliance with potassium citrate pills.

Moonstone contains a patented blend of citrate salts from potassium and magnesium as well as sodium. This blend makes it safe for over-the-counter use without the need for a prescription. Moonstone is considered a low sodium product, only 4% of daily value, and the sodium comes from sodium citrate (alkali citrate salt) and not sodium chloride (table salt). The amount of sodium in this formula has been kept to minimum levels because sodium can increase the amount of calcium in the urine as well as increase blood pressure. The citrate salt is less likely to have this effect.

Moonstone may be an effective alternative for patients with high potassium levels for whom potassium citrate is contraindicated. It may also be effective for those who find potassium citrate tablets too large or difficult to swallow, and for those who have unwanted/intolerable side effects from potassium citrate such as gastric upset. One packet of Moonstone contains 30 milliequivalents of alkali citrate; this is equivalent to the amount of citrate found in two potassium citrate tablets. Both Moonstone and potassium citrate pills are effective at raising urinary citrate and pH.

Moonstone contains clinically significant amounts of citrate-as-alkali to increase urine citrate and pH, which is known to make the kidneys less hospitable to the formation of kidney stones, namely: calcium oxalate, calcium phosphate, cystine and uric acid stones. However, clinical studies are needed to determine the precise efficacy of Moonstone beverages.

Moonstone is ideal for diabetics, since it uses allulose, a rare non-absorbable sugar that occurs naturally in raisins, figs and other foods. Allulose tastes similar to sugar but has virtually no calories. With a glycemic index of zero, allulose has no impact on blood glucose.

Patients following low-carb or higher protein diets tend to have more acid in their urine, which increases the kidney’s reabsorption of citrate, reducing the amount of available citrate in the urine. Patients who consume large amounts of high-sodium foods will likely have more calcium in their urine. Both scenarios are conducive to kidney stone formation, and those patients may benefit from the addition of dietary alkali citrate such as Moonstone.

The potassium content of a serving of Moonstone is less than that of a banana and should not be a problem for people with stages 3 or 4 CKD.  A banana has 12 mEq of potassium. 1 packet of Moonstone has 5.3 mEq of potassium. Potassium comes from all fruits and vegetables, as well as from animal protein. It is nearly impossible to eat a diet that has NO potassium. That is why some people with CKD have to take sodium polystyrene sulfonate (Kayexalate), Lokelma or Veltassa. People with kidney disease also need alkali (also known as base), like citrate, because of metabolic acidosis.  Alkali MUST include a cation (a positively charged molecule) such as sodium or potassium. The risk of high blood potassium or high blood pressure is a lot LESS when the potassium or sodium is given as “potassium citrate” or “sodium citrate” than if it’s given as “potassium chloride” or “sodium chloride” (salt) even with advanced CKD.  Moonstone’s patented formula uses potassium citrate, making it a safer option for CKD patients.  For any health-related questions or if you are taking medications, please discuss with your physician.
