Berberine and Cinnamon Extract: what the published research says

PubMed indexes 3 records that name Berberine and Cinnamon Extract together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Berberine and Cinnamon Extract. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

3 studies naming Berberine and Cinnamon Extract.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Role of Fenugreek, Cinnamon, Curcuma longa, Berberine and Momordica charantia in Type 2 Diabetes Mellitus Treatment: A Review.

Pharmaceuticals (Basel, Switzerland) · 2023 · PMID 37111272

Review

“Among these, fenugreek, cinnamon, Curcuma longa, berberine, and Momordica charantia have demonstrated different degrees of hypoglycemic activity in clinical studies and animal models. Therefore, the aim of this review is to synthesize the mechanisms of action of five medicinal plants, as well as the experimental and clinical evidence of their hypoglycemic activity from the published literature.”

Cortez-Navarrete et al. · From the abstract

Names both Berberine and Cinnamon Extract in its title.

Effects of cinnamon granules on pharmacokinetics of berberine in Rhizoma Coptidis granules in healthy male volunteers.

Journal of Huazhong University of Science and Technology. Medical sciences = Hua zhong ke ji da xue xue bao. Yi xue Ying De wen ban = Huazhong keji daxue xuebao. Yixue Yingdewen ban · 2011 · PMID 21671182

Human subjects

“The C(max), T(max), t(1/2) and CLz/F of berberine in Rhizoma Coptidis granules were 360.883 μg/L, 2.0 h, 3.882 h, 119.320 L·h(-1)·kg(-1) respectively, and those of berberine in JTW were 396.124 μg/L, 1.5 h, 4.727 h, 57.709 L·h(-1)·kg(-1) respectively. It was suggested that Rhizoma Coptidis granules combined with Cinnamon granules could increase the plasma concentration of berberine, promote berberine absorption and lengthen the detention time of berberine in healthy male…”

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Berberine, Cinnamon Extract, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
