Berberine

Cholesterol and triglycerides is the main area connected here, and any felt benefit should be read together with the human evidence base.

The 56.0 score includes research signals from patient or disease contexts. General supplement evidence is not repeated enough, so the B tier remains conservative.

Representative tier calculated from paper evidence that passed the collection audit.

Key Evidence #1
Public scholarly dataCitation signal: 343
observational

Findings indicate that BBR, in addition to upregulating the LDLR, inhibits lipid synthesis in human hepatocytes through the activation of AMPK, which could account for the strong reduction of plasma TGs observed with this drug in clinical trials.

Key Evidence #2
Public scholarly dataCitation signal: 316
observational

It is demonstrated in a randomized controlled trial that effects of berberine, a plant alkaloid known to lower blood glucose, may be explained by the inhibition of Ruminococcus bromii mediated biotransformation of the bile acid deoxycholic acid.

Key Evidence #3
Public scholarly dataCitation signal: 287
review

Examples in the pharmacokinetics field, obesity, hyperlipidaemia, diabetes, cancer, inflammatory disease conditions, etc are used to show the link between the gut microbiota and the polypharmacology of berberine.

It is shown that the gut microbiota converts BBR into its absorbable form of dihydroberberine (dhBBR), which has an intestinal absorption rate 5-fold that of BBR in animals.

Investigation of the anti-colitis activity and potential mechanism of oxyberberine (OBB), a novel gut microbiota metabolite of BBR, in DSS-induced colitis mice revealed that OBB effectively improved D SS-induced experimental colitis, at least partly through ma

A deeper understanding of berberine's effectiveness is delves into by integrating network pharmacology and molecular docking techniques in the context of treating inflammatory diseases, providing guidance and reference for berberine's subsequent revelation of
