Type of study modelExperimental method [subject (age/weight), treatment dosage, duration of treatment]Major activityMechanism of actionReference

In vivo studyHigh fat diet (HFD) male Wistar rats (200–220 g), DSW 1,000 hardness, ad libitum, 4 weeksIncreased the level of HDL-C.ND.[19]

In vivo studyCholesterol-fed diet (CFD) male New Zealand white rabbits (1500–2000 g) fed diet containing 3.75, 37.5, and 75 mg/kg of Mg, DSW 1410 hardness, 8 weeks Improved plasma total cholesterol (TC), triglyceride (TG), and LDL-C levels.
Improved the protein expression of AMPK phosphorylation, ACC phosphorylation, and HMGCR.[6]

In vivo studyHigh cholesterol diet (HCD) ICR mice (7 weeks), reverse osmosis (RO DSW) (44.6 hardness), electrodialysis (ED DSW) (4685.9 hardness) and 10% (v/v) dilution with ddH2O 10% DSW (544.2 hardness), ad libitum, 8 weeksReduced the level of TG, TC, and non-high-density lipoprotein cholesterol (non-HDL-C) levels in the serum and liver of animal models, respectively.Increase in daily faecal lipid of TG and TC and bile acid outputs.
[20]
HFD Hamster (5 weeks), DSW 300, 900, 1500 hardness, ad libitum, 6 weeksIncrease in daily faecal lipid of TG and TC and bile acid outputs.
Upregulated hepatic low-density-lipoprotein receptor (LDL receptor) and cholesterol-7a-hydroxylase (CYP7A1) gene expressions.

Type of study modelMale hyperlipidemia rabbits (1.8–2.0 g), DSW 1200 hardness, 150 ml/d, ad libitum, 12 weeksReduced plasma TC and plasma LDL cholesterol level.
Increased plasma HDL cholesterol.

In vivo studyMale Wistar rats (90 g), DSW containing 200, 600, and 1000 mg/L of Mg, ad libitum, 4 weeksAttenuated plasma TC.ND.[22, 23]

Clinical studyHypercholesterolemic individuals (23 men and 19 women), DSW (1410 hardness), supplemented 1050 mL daily, 6 weeks Decreased serum TC and low-density lipoprotein cholesterol (LDL-C).
Decreased lipid peroxidation in hypercholesterolemic subjects.[4]

Clinical studyCFD and hyperlipemia male Japanese rabbits, DSW hardness of 28, 300, and 1200, 150 ml/d, ad libitum, 4 weeksReduced TC and LDL-C levels in hyperlipemia rabbits.
Prevented increase of TC and LDL-C levels in CFD rabbits.
