We became one of the 17 pioneer manufacturers in Japan—just one of three in Tokyo—to be certified under The Japanese Institute for Health Food Standard’s Good Manufacturing Practice (GMP) program for dietary supplements as of June 2014. GMP is a regime aimed to ensure consistent quality by preventing human error, contamination and quality deterioration throughout the entire manufacturing process.

The safety of WOL products has been confirmed, not only by Japanese healthcare institutions but also the Tokyo Metropolitan Institute of Public Health, and they can be safely taken by people of all ages, including those who are pregnant and lactating, to compliment their diet for better health.
