Leep Inc. (Headquarters: Minato-ku, Tokyo) is pleased to announce that its supplement brand "Nature In" has obtained the global anti-doping certification program "Informed Choice" for its product "Nature In Creatine."

Informed Choice is a third-party certification system operated with the aim of quality control for sports supplements and reducing the risk of contamination with prohibited substances. With this certification, Nature In has further strengthened the quality control system for its creatine products, creating an environment where athletes and general sports enthusiasts can choose with greater peace of mind.

■ Background
In recent years, the creatine supplement market has been rapidly expanding, while price competition has also intensified. Nature In, based on the philosophy that price and quality are not mutually exclusive but can coexist, has been investing not only in price but also in quality assurance. Obtaining the Informed Choice certification is one of these initiatives.

■ Objective Quality Assurance through Third-Party Certification
Creatine is widely distributed with overseas raw materials, making it impossible to judge quality solely by the country of origin of the raw materials. Furthermore, manufacturing bases and quality control systems are areas that are difficult for consumers to grasp. Nature In believes it is important not only to claim safety itself but also to provide objective standards that customers can choose with confidence, and thus obtained the third-party certification, Informed Choice.

■ About Informed Choice
Informed Choice is an anti-doping certification program operated by LGC Group, a UK quality assurance organization. To obtain certification, the following items must be met:

- Quality audit of manufacturing facilities
- Verification of manufacturing processes
- Regular testing for prohibited substances

Only products that meet strict standards are permitted to use the certification mark and are widely recognized by professional athletes, sports teams, and training facilities worldwide.

■ Commitment to Ease of Use
Nature In believes that there is value in being able to use products continuously every day, and therefore pays attention to ease of use as follows:

- Adoption of an easy-to-open and close zipper
- Inclusion of a measuring spoon
- Price design that allows for continuation despite large capacity
