hydroxycitrate dosage for kidney stones
Most kidney stones with a diameter of less than 5 millimeters, and about half of all stones between 5 and 10 millimeters, pass out of the body on their own. Metrics Abstract Alkali supplements are used to treat calcium kidney stones owing to their ability to increase urine citrate excretion which lowers stone risk by inhibiting crystallization and complexing calcium. Researchers at the University of Houston sought to determine whether or not hydroxycitrate (HCA) was an effective inhibitor of calcium oxalate crystal growth. HCA was also tested in human subjects, as seven people took the supplement for three days, allowing researchers to determine that HCA is excreted through urine, a requirement for the supplement to work as a treatment. Hydroxycitrate is a structural analog of citrate, widely available as an over-the-counter supplement for weight reduction.

How can it not? If we make these assumption of honesty and skill, the marked downward skew from alkali is just too large to be by chance. The reason is that calcium phosphate supersaturation requires divalent phosphate be present, and the pKa for the second proton is about 6.8.
