hmm I need to find the original study
In a trial completed at Arkansas State University, researchers examined whether co-ingestion of D-pinitol with creatine affects whole body creatine retention. The results show that D-Pinitol increases whole body creatine retention to the same extent as high levels of carbohydrate or carbohydrate and protein, making this a suitable and very optimistic compound for sports application.
The effects of Pinitol have been described by noted experts such as Dr. Daniel Gwartney, M.D. Writing in Ironman magazine, Gwartney points out that "... of all the proposed so-called insulin mimickers and insulin co-factors, pinitol is the one with the most promise." The effectiveness of Pinitol has been known by top US experts for some time, and it has been awarded two U.S. Patents (#5,550,166 and #5,827,896).
D-pinitol will increase creatine uptake to the same extent as large doses of carbohydrate, but without the extra calories and sugar. This will lead to faster muscle growth, greater strength and an increase in power output. It will also mean better health and care of your pancreas and secretion of insulin in safe and effective doses instead of overdosing.
