| Water intake (mL) | 10 ± 2.4 | 9.7 ± 1.8 | 10 ± 1.7 | 10 ± 1.6 | 10 ± 1.3 | 7.9 ± 0.9 |
| Urine excretion (mL/24 h) | 3.4 ± 0.9 | 2.3 ± 0.4 | 3.8 ± 0.7 | 3.7 ± 0.7 | 3.3 ± 0.4 | 3.5 ± 0.6 |

Cnnm2+/+ and Cnnm2+/− mice were kept in metabolic cages exposed at low (0.02%), normal (0.21%) and high (0.48%) (w/w) Mg2+ diets for 14 days. The last 48 h, mice were kept in metabolic cages for the collection of urine and faeces. Values represent the latter 24 h (mean ± SEM). M male, F female.
