Potassium and Calcium: study protocols
10 study groups took Potassium together with Calcium. These are the doses the studies gave. They are not a recommendation.
Dose per serving from research: Potassium
9 study groups in 5 studies say how much Potassium participants took a day.
These are the doses the studies gave. They are not a recommendation.
Most common: 50 mmol to 100 mmol, 67% of 9 study groups.
| Daily dose | Study groups |
|---|---|
| 10 mmol or less | 1 |
| 10 mmol to 25 mmol | 0 |
| 25 mmol to 50 mmol | 2 |
| 50 mmol to 100 mmol | 6 |
Dose per serving from research: Calcium
5 study groups in 3 studies say how much Calcium participants took a day.
These are the doses the studies gave. They are not a recommendation.
Most common: 500 mg to 1 g, 100% of 5 study groups.
| Daily dose | Study groups |
|---|---|
| 500 mg to 1 g | 5 |
Commonly used together
8 of 10 study groups took Potassium and Calcium with something else, but nothing that 3 or more different studies gave.
