In the Summer 2024 edition of the research magazine of Parkinson’s UK, I was surprised to see page 14: parkinsons.org.uk/sites/def...
"Clinical trial results showing potential for Symprove"
"Covid-19 hugely delayed this research but the initial results have now been shared."
"The results suggest that Symprove alters gut bacteria, changing levels of certain bacteria that might have an overall beneficial effect. Symprove also seems to be helping Parkinson’s drugs to work more quickly (achieving quicker ‘time-to-ON’) and therefore helping with movement symptoms. There is also evidence to suggest an improvement in non-motor symptoms, especially in anxiety, fatigue, constipation and sleep"
"We are waiting on the publication of the full results and will be working to understand what’s next. The results from this study offer more evidence for probiotic use in Parkinson’s."
The only published results I can find are from April 2024: Effects of a four-strain probiotic on inflammatory markers in Parkinson’s disease: a multicentre randomised controlled trial (the SymPD study) neurology.org/doi/10.1212/W...
This paper also refers to "Preliminary results from the SymPD trial suggest that this four-strain probiotic can enrich the gut microbiota with bacteria having anti-inflammatory properties, reduce ‘time to on’, and non-motor symptoms burden in patients with PD and constipation."
But when will they publish the full results and why does it take so long?!
