PREPD Hydration is backed by over 20 years of collaborative medical research between Flinders and Yale Universities. The original clinical research devised a better oral rehydration solution (ORS) to treat severe dehydration arising from diseases like cholera and rotavirus for people living in developing countries.

Traditional World Health Organisation (WHO) ORSs only trigger fluid absorption in the small intestine, and fail to trigger the absorption capacity of the large intestine (up to 5L per day). The Prepd Hydration research team identified a unique resistant starch, which was able to promote absorption of fluid in the large intestine whilst maintaining optimal absorption in the small intestine. This new formulation was able to improve hydration by 39% when compared with the WHO recommended ORS (Ramakrishna et al 2000).

Using the same unique patent-pending resistant starch, PREPD was adapted from this ground-breaking medical research (Binder et al 2014) to boost hydration and meet the fluid loss needs of athletes. While their founders still pursue the goal to reduce severe dehydration in developing countries, they also share our vision to pioneer a new frontier in sports hydration and performance.


While carb-loading has been a popular approach for athletes to meet energy requirements in endurance sports, until now there has been no equivalent for hydration. After all, the human body can’t store water in reserve. However, using the unique resistant starch in PREPD, we can prime the body to be able to boost hydration and increase fluid absorption.

The PREPD two-step system has been specifically developed to boost the body’s hydration effectiveness before, during and after intense exertion.


01> PRIME: PREPD Prime is a pre-workout hydration enhancer consumed 6-18 hours before training and competition. PRIME is designed to deliver an optimal dose of our unique resistant starch to prepare the gut to be able to use its full hydration potential. This helps you start better hydrated and absorb fluid more effectively when you need to perform.


02> RECOVER: PREPD Recover is a post-workout rehydration enhancer consumed immediately after training and competition. RECOVER is hypotonic (low in sugar) and has an optimal blend of electrolytes to rapidly replenish fluids and salts. In addition, added resistant starch provides a rehydration boost in the 24 hours following exertion.
