| name | Calcium Citrate |
| classification | Dietary Supplement, Calcium Supplement |
| pharmacokinetics | Calcium citrate is readily absorbed from the gastrointestinal tract, especially in the presence of adequate stomach acid. Peak plasma calcium levels are generally reached within 1-3 hours after oral administration. The absorption of calcium citrate can be affected by factors such as the presence of other food components and the amount of stomach acid present. The absorbed calcium is primarily excreted through the kidneys. |
| suggested dosage | | general | The recommended dosage of calcium citrate varies based on individual needs and the presence of any underlying conditions. Consult a healthcare professional for personalized recommendations. | | example dosage | A common dosage range is 250-500 mg of elemental calcium per dose, 2-3 times daily. The exact amount of calcium citrate needed will vary with the specific product used. | | weight and age considerations | In a healthy 25-year-old male weighing 70 kg, a dosage of 600 mg calcium citrate per day (or 1500 mg per day with calcium citrate powder or supplements that provide a lower dose of elemental calcium) may be appropriate if dietary intake is low. This is a general guideline and should be reviewed with a healthcare professional. | | important note | Always follow the instructions provided on the specific calcium citrate product's label or consult a healthcare professional before adjusting the dosage. |
