Plasma Endocannabinoids Are Independently Associated With the Metabolic Function of White Adipose Tissue

J Clin Endocrinol MetabPublished Mechanistic study

Authors' conclusion

EC levels of the NAE family independently follow plasma NEFA metabolism, whereas 2-MAG closely follow the spillover of triglyceride-rich lipoprotein intravascular lipolytic products. Whether these associations are causal requires further investigation.
