Conclusion: Subgroup analysis suggests the need to investigate any relative contributions of geographical differences on PCOS phenotypes. These findings may provide the basis for the development of strategies and best practices toward a standardized definition of PCOM and a more accurate ultrasonographic evaluation of PCOS.

Conclusion: The results of this systematic review and meta-analysis suggest that PEA is an effective and well-tolerated treatment for chronic pain. Further study is warranted to determine the optimal dosing and administration parameters of PEA for analgesic effects in the context of chronic pain.
PubMed 36986081 ↗Conclusion: In people without diabetes, adding dairy or plant protein to a carbohydrate-containing meal elicits physiologically significant reductions in glucose AUC and increases insulin AUC. Animal protein may slightly reduce the glucose AUC and may increase the insulin AUC. In people with T2DM, protein may not have such large and consistent effects. Further research is needed to determine if the effects of protein differ by health status and protein source. This study was registered at PROSPERO as CRD42022322090.
PubMed 39019167 ↗Conclusion: Furthermore, both rehabilitation strategies and PEA-LUT administration have been associated with improvements in symptoms of brain fog. Future studies should explore combinations of interventions and include longer follow-up periods to assess the long-term effects of these treatments.

“Try supplementing with PEA”
“PEA (Phenylethylamine) - 500mg weekly or biweekly”
“PEA most likely does a real number on your heart considering it increases blood pressure and causes vasoconstriction”
“I plan to try various other things to alleviate this next time, i.e CDP Choline to upregulate dopamine receptors, Tyrosine/PEA and maybe grapefruit juice for metabolism reduction.”
