D-Pinitol is widely used in the pharmaceutical and nutraceutical industries due to its insulin-mimetic properties, making it beneficial in managing type 2 diabetes. It helps lower blood glucose levels by enhancing glucose uptake in cells, similar to insulin. It is also studied for its anti-inflammatory and antioxidant effects, supporting its use in dietary supplements aimed at metabolic health.

In sports nutrition, D-Pinitol is included in supplements to improve muscle recovery and support protein synthesis, potentially enhancing exercise performance and lean mass gains. Additionally, it has shown promise in improving fertility in men with metabolic disorders by supporting hormonal balance and sperm quality.

Agriculturally, D-Pinitol acts as a natural osmoprotectant in plants, helping them withstand drought and salinity stress. This property is being explored in crop science to develop more resilient plant varieties. It is also used in research as a reference compound in studies involving inositol metabolism and signal transduction pathways.
