Severity
Info
Evidence
moderate
Timing
Together, no conflict.
How it works
Potassium citrate alkalinises urine, which reduces renal calcium excretion and may support calcium balance.
High dietary potassium is associated with better bone density in observational studies. The mechanism is likely the alkalinising effect on urine pH, which reduces the amount of calcium the kidneys excrete.
What to do
Take together without concern. No separation needed. Potassium citrate is the preferred form if supporting calcium balance.
