TL;DR
Drinking water with added hydrogen gas can reduce the development of artery-clogging disease in mice genetically prone to such conditions.
Key Finding
Mice that drank hydrogen-enriched water developed significantly fewer atherosclerotic lesions in their arteries and showed reduced oxidative stress in aortic tissue compared to controls.
Summary
Researchers gave mice genetically engineered to develop atherosclerosis (a buildup of plaque in arteries) hydrogen-enriched water to drink for four months. The mice that drank hydrogen water developed significantly fewer atherosclerotic lesions in their arteries compared to control mice, and their aortic tissue showed lower levels of oxidative stress (cellular damage from unstable molecules). This suggests hydrogen water may help prevent artery disease by reducing harmful oxidative stress.
Practical Takeaway
This early-stage animal study suggests hydrogen water may help prevent atherosclerosis by reducing oxidative stress, but the findings are limited to mice with a genetic predisposition to the disease. Human clinical trials would be needed to determine whether these results apply to people. The study does not provide evidence that hydrogen water would prevent or treat atherosclerosis in humans.
Abstract
Oxidative stress is implicated in atherogenesis; however most clinical trials with dietary antioxidants failed to show marked success in preventing atherosclerotic diseases. We have found that hydrogen (dihydrogen; H(2)) acts as an effective antioxidant to reduce oxidative stress [I. Ohsawa, M. Ishikawa, K. Takahashi, M. Watanabe, K. Nishimaki, K. Yamagata, K. Katsura, Y. Katayama, S, Asoh, S. Ohta, Hydrogen acts as a therapeutic antioxidant by selectively reducing cytotoxic oxygen radicals, Nat. Med. 13 (2007) 688-694]. Here, we investigated whether drinking H(2)-dissolved water at a saturated level (H(2)-water) ad libitum prevents arteriosclerosis using an apolipoprotein E knockout mouse (apoE(-/-)), a model of the spontaneous development of atherosclerosis. ApoE(-/-) mice drank H(2)-water ad libitum from 2 to 6 month old throughout the whole period. Atherosclerotic lesions were significantly reduced by ad libitum drinking of H(2)-water (p=0.0069) as judged by Oil-Red-O staining series of sections of aorta. The oxidative stress level of aorta was decreased. Accumulation of macrophages in atherosclerotic lesions was confirmed. Thus, consumption of H(2)-dissolved water has the potential to prevent arteriosclerosis.
