A new scientific review has examined whether natural foods and plant compounds can support the body’s own GLP-1 activity, the same hormone system targeted by medications like Ozempic and Mounjaro. The findings suggest that certain ingredients found in grocery stores and kitchens may play a supporting role in appetite regulation, blood sugar balance, and metabolic health.
What the research says
The review, published in Toxicology Reports, analyzed decades of data on how foods, herbs, and bioactive compounds influence glucagon-like peptide-1 (GLP-1). This hormone is produced in the gut and helps signal fullness to the brain, stimulate insulin release, lower blood sugar after meals, and slow digestion to keep a person satisfied longer.
Scientists combed through studies on teas, spices, amino acids, plant polyphenols, and fermented foods. They looked for compounds that consistently triggered GLP-1 release or improved the body’s sensitivity to it. While nothing worked as powerfully as prescription medications, several ingredients repeatedly showed measurable effects.
Top natural GLP-1 supporters
The most researched natural GLP-1 supporters included:
- Berberine
- Cinnamon extract
- Ginger and gingerol
- Green tea and post-fermented tea compounds
- Curcumin from turmeric
- Wheat protein, found in fiber-rich breads
- Quercetin-rich plant foods such as onions, apples, berries, cherries, grapes, kale and spinach
The mechanisms varied. Some compounds activated bitter taste receptors in the gut. Others stimulated pathways like AMPK and ERK that regulate hormone secretion. But many pointed toward the same outcome: increased GLP-1 activity.
Why it matters
Researchers emphasized that exploring natural GLP-1 modulators is not about replacing medication. It is about giving people more options. Reasons to care include accessibility, since GLP-1 medications are not affordable or available to everyone; tolerance, because some people experience nausea, diarrhea, or appetite suppression that feels too intense; preference, as many individuals favor a nutrition-forward or natural-first approach; and personalization, since having multiple tools allows for more tailored metabolic care.
The review ultimately aims to find ways to support people who want metabolic improvements but may not want, need, or tolerate a prescription.
The study was published in Toxicology Reports and is available through ScienceDirect.
