Drinking Refined Deep-Sea Water: Impact on Gut Ecosystem & Intestinal Health

Drinking Refined Deep-Sea Water: Impact on Gut Ecosystem &  Intestinal Health

News Release, International Society of Microbiota, France – April 6, 2022

World health trends are focusing on a balanced food and beverage intake for healthy life. Refined deep-sea water (RDSW), obtained from deep-sea water collected offshore in Muroto (Japan), is mineral-rich drinking water. 

Knowing that drinking RDSW improves human gut health, Takeuchi et al, analyzed the effect of drinking RDSW on the gut ecosystem to understand this effect.
In a randomized double-blind controlled trial, ninety-eight healthy adults were divided into two groups: RDSW or mineral water (control).
  1. The participants consumed 1 L of either water type daily for 12 weeks.
  2. A self-administered questionnaire and stool and urine samples were collected through the intervention.
The following results were determined: fecal biomarkers of secretory immunoglobulin A (sIgA), five putrefactive products, and nine short-chain-fatty-acids (SCFAs) as the primary outcomes; and three urinary isoflavones and the questionnaire as secondary outcomes.

In conclusion, drinking RDSW was found to improve the intestinal environment by increasing fecal SCFAs and urinary isoflavones, which leads to broad beneficial effects in human.
