7-20This article discusses preliminary research indicating that the ketosis-inducing supplement 1,3-butanediol (BD) shows promise for neuroprotection. A study in rats found that BD administration improved neuronal health and signaling in the hippocampus, with key benefits observed to be distinct from those achieved through mere calorie restriction. While these findings are promising, they are preliminary and require further investigation to determine clinical significance in humans.
The Neuroprotective Promise of 1,3-Butanediol (BD)
- 1,3-butanediol (BD) is a supplement that induces ketosis by converting to β-hydroxybutyrate (βHB) in the liver, offering an alternative to strict ketogenic diets.
- A study by Cigliano et al. found that BD treatment in rats led to significant improvements in inflammation and oxidative stress markers in the hippocampus.
- BD promoted neuronal health and neural signaling, increasing critical proteins for neuronal growth (BDNF) and synaptic function (synaptophysin, synaptotagmin).
Unique Benefits Beyond Calorie Restriction
- The study design included pair-fed control groups, enabling researchers to differentiate BD's specific effects from those attributable to caloric restriction.
- BD uniquely reduced markers of endoplasmic reticulum (ER) stress in treated animals compared to both ad-libitum and pair-fed controls.
- Increases in BDNF and synaptic function proteins were observed exclusively in BD-treated animals, indicating benefits beyond lower energy intake.
Preliminary Findings and Future Directions
- The research is based on preclinical animal studies and is considered very preliminary, lacking functional assessments of cognitive improvement.
- The study did not compare BD treatment directly against a true ketogenic diet, and the achieved ketosis levels were lower than diet-induced ketosis.
- Despite limitations, the findings provide proof-of-principle that ketosis-inducing supplements may offer unique neuroprotective benefits, potentially serving as an alternative for individuals unable to adhere to strict ketogenic diets.
- 1,3-butanediol holds FDA GRAS status, and small clinical trials are currently exploring its efficacy for blood glucose management and alcohol use disorder.
