Unique Plant-Based Magnesium Option
Tsuno Rice Fine Chemicals Co., Ltd. Unveiled findings from a human study indicating that its Rice Magnesium product offers gradual and sustained magnesium absorption. Conducted in Wakayama, Japan, the study highlights potential benefits in areas such as sleep maintenance and muscle fatigue management.
Rice Magnesium is derived from Japanese rice bran and developed through extensive research. It is composed of magnesium phosphate and is distinct from other mineral-derived magnesium products on the market.
The study involved 10 healthy adults who consumed four different magnesium supplements, each containing 300 mg of magnesium. Results showed that Rice Magnesium had a superior absorption profile, maintaining elevated blood magnesium levels for several hours.
Magnesium is an essential mineral involved in various physiological functions, including sleep support, stress management, and muscle conditioning. Insufficient intake can increase the risk of lifestyle-related health issues.
In 2025, Japan’s Ministry of Health, Labour and Welfare recommended a daily intake of 330–380 mg for adult men and 270–290 mg for adult women. However, the ministry’s 2024 National Health and Nutrition Survey indicates that many Japanese people are not meeting these levels. The U.S. National Institutes of Health also reports that many Americans fall short in magnesium intake.
Potential Applications and Market Expansion
Rice Magnesium’s absorption characteristics make it suitable for use in magnesium-fortified foods and natural supplements. It has already been adopted in markets like Taiwan, South Korea, and Europe, with potential for expansion to the United States.
According to the study, Rice Magnesium could help in supporting sleep quality, managing muscle fatigue during exercise, and aiding in bowel regularity. Tsuno Rice Fine Chemicals aims to expand the product’s reach in Japan and internationally.
The magnesium supplement market is growing globally, with a variety of ingredients being selected for specific health needs and product applications. Rice Magnesium, with its unique absorption profile, is poised to capture a significant market share.
Established in 1947, Tsuno Group Co., Ltd. Focuses on the advanced utilization of rice bran. The company also produces rice bran oil and extracts functional ingredients for various industries, including pharmaceuticals and food additives.
