A review published in Toxicology Reports examined decades of data on how foods, herbs and bioactive compounds influence glucagon-like peptide-1 (GLP-1), the hormone targeted by medications such as Ozempic and Mounjaro. Researchers analyzed studies on teas, spices, amino acids, plant polyphenols and fermented foods to see which compounds consistently affected GLP-1 release or activity.
GLP-1 is produced in the gut and helps signal fullness to the brain, stimulate insulin release, reduce blood sugar after meals and slow digestion. The review found that while no natural substance works as powerfully as prescription medications, some ingredients repeatedly triggered increases in GLP-1 release or improved the body’s sensitivity to it.
What they found
The most researched natural GLP-1 supporters include berberine, cinnamon extract, ginger and gingerol, green tea and post-fermented tea compounds, curcumin from turmeric, wheat protein found in fiber-rich breads, and quercetin-rich plant foods such as onions, apples, berries, cherries, grapes, kale and spinach. The mechanisms varied, from activating bitter taste receptors in the gut to stimulating pathways like AMPK and ERK that regulate hormone secretion, but many pointed toward the same outcome: increased GLP-1 activity.
Why these natural GLP-1 supporters matter
Researchers emphasized that exploring natural GLP-1 modulators is not about replacing medication but about giving people more options. Reasons include accessibility, as GLP-1 medications are not affordable or available to everyone; tolerance, as some people experience nausea, diarrhea or appetite suppression that feels too intense; preference for a nutrition-forward or natural-first approach; and personalization, allowing for more tailored metabolic care. The research aims to support people who want metabolic improvements but may not want, need, or tolerate a prescription.
The takeaway
Emerging research shows that compounds such as berberine, cinnamon, ginger, curcumin and green tea can meaningfully support the same metabolic pathways influenced by GLP-1, including appetite regulation, satiety and healthy blood sugar balance. For anyone exploring natural metabolic support, these ingredients can be powerful additions to a well-rounded lifestyle, especially when paired with thoughtful nutrition and movement.
