Effects of alkaline reduced water (ARW) on the scavenging of reactive oxygen species (ROS) and diabetes were recently reported. However, no studies have yet been investigated on general drinking effects. In this study, we examined 100 patients hospitalized for senile disease treatment and recuperation. All examines received the ARW for 2 months. WBC level was decreased from $6.34pm1.9( imes10^9/L)$ to $5.66pm1.7( imes10^9/L)$. SGPT level was decreased from 27.47$pm$14 Ut to 23.95$pm$8.8 U/L. Cholesterol level was increased from 167.9$pm$32 mg/dl to 176.21$pm$42 mg/dl within normal range. However, the levels of potassium, adiponectin, SGOT and blood pressure showed no significant difference. The levels of growth hormone and homocysteine and mini-mental state examination also showed no significant difference. We suppose that the slight blood parameter trends indicate an improved physical condition induced by the ARW. Furthermore, we could found no harmful effect of the ARW in this study.
